delete-service

Description

Deletes a specified service within a cluster. You can delete a service if you have no running tasks in it and the desired task count is zero. If the service is actively maintaining tasks, you can’t delete it, and you must update the service to a desired task count of zero. For more information, see UpdateService .

Note

When you delete a service, if there are still running tasks that require cleanup, the service status moves from ACTIVE to DRAINING , and the service is no longer visible in the console or in the ListServices API operation. After all tasks have transitioned to either STOPPING or STOPPED status, the service status moves from DRAINING to INACTIVE . Services in the DRAINING or INACTIVE status can still be viewed with the DescribeServices API operation. However, in the future, INACTIVE services may be cleaned up and purged from Amazon ECS record keeping, and DescribeServices calls on those services return a ServiceNotFoundException error.

Warning

If you attempt to create a new service with the same name as an existing service in either ACTIVE or DRAINING status, you receive an error.

Synopsis

  delete-service
[--cluster <value>]
--service <value>
[--force | --no-force]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--cluster (string)

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the service to delete. If you do not specify a cluster, the default cluster is assumed.

--service (string)

The name of the service to delete.

--force | --no-force (boolean)

If true , allows you to delete a service even if it wasn’t scaled down to zero tasks. It’s only necessary to use this if the service uses the REPLICA scheduling strategy.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples

To delete a service

The following ecs delete-service example deletes the specified service from a cluster. You can include the --force parameter to delete a service even if it has not been scaled to zero tasks.

aws ecs delete-service --cluster MyCluster --service MyService1 --force

For more information, see Deleting a Service in the Amazon ECS Developer Guide.

Output

service -> (structure)

The full description of the deleted service.

serviceArn -> (string)

The ARN that identifies the service. For more information about the ARN format, see Amazon Resource Name (ARN) in the Amazon ECS Developer Guide .

serviceName -> (string)

The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster. However, you can have similarly named services in multiple clusters within a Region or across multiple Regions.

clusterArn -> (string)

The Amazon Resource Name (ARN) of the cluster that hosts the service.

loadBalancers -> (list)

A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.

(structure)

The load balancer configuration to use with a service or task set.

For specific notes and restrictions regarding the use of load balancers with services and task sets, see the CreateService and CreateTaskSet actions.

When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.

We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.

A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .

targetGroupArn -> (string)

The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you’re using a Classic Load Balancer, omit the target group ARN.

For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .

For services using the CODE_DEPLOY deployment controller, you’re required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .

Warning

If your service’s task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

loadBalancerName -> (string)

The name of the load balancer to associate with the Amazon ECS service or task set.

A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

containerName -> (string)

The name of the container (as it appears in a container definition) to associate with the load balancer.

containerPort -> (integer)

The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they’re launched on must allow ingress traffic on the hostPort of the port mapping.

serviceRegistries -> (list)

The details for the service discovery registries to assign to this service. For more information, see Service Discovery .

(structure)

The details for the service registry.

Each service may be associated with one service registry. Multiple service registries for each service are not supported.

When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.

registryArn -> (string)

The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .

port -> (integer)

The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

containerName -> (string)

The container name value to be used for your service discovery service. It’s already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can’t specify both.

containerPort -> (integer)

The port value to be used for your service discovery service. It’s already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can’t specify both.

status -> (string)

The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .

desiredCount -> (integer)

The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .

runningCount -> (integer)

The number of tasks in the cluster that are in the RUNNING state.

pendingCount -> (integer)

The number of tasks in the cluster that are in the PENDING state.

launchType -> (string)

The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.

capacityProviderStrategy -> (list)

The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.

(structure)

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.

A capacity provider strategy may contain a maximum of 6 capacity providers.

capacityProvider -> (string)

The short name of the capacity provider.

weight -> (integer)

The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can’t be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.

An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that’s run using capacityProviderA , four tasks would use capacityProviderB .

base -> (integer)

The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

platformVersion -> (string)

The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn’t specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .

platformFamily -> (string)

The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.

All tasks that run as part of this service must use the same platformFamily value as the service (for example, LINUX ).

taskDefinition -> (string)

The task definition to use for tasks in the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .

deploymentConfiguration -> (structure)

Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

deploymentCircuitBreaker -> (structure)

Note

The deployment circuit breaker can only be used for services using the rolling update (ECS ) deployment type.

The deployment circuit breaker determines whether a service deployment will fail if the service can’t reach a steady state. If deployment circuit breaker is enabled, a service deployment will transition to a failed state and stop launching new tasks. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

enable -> (boolean)

Determines whether to use the deployment circuit breaker logic for the service.

rollback -> (boolean)

Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

maximumPercent -> (integer)

If a service is using the rolling update (ECS ) deployment type, the maximumPercent parameter represents an upper limit on the number of your service’s tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.

If a service is using either the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.

minimumHealthyPercent -> (integer)

If a service is using the rolling update (ECS ) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service’s tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.

For services that do not use a load balancer, the following should be noted:

  • A service is considered healthy if all essential containers within the tasks in the service pass their health checks.

  • If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.

  • If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.

For services are that do use a load balancer, the following should be noted:

  • If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

  • If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

If a service is using either the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

taskSets -> (list)

Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.

computedDesiredCount -> (integer)

The computed desired count for the task set. This is calculated by multiplying the service’s desiredCount by the task set’s scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.

pendingCount -> (integer)

The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it’s restarted after being in the STOPPED state.

(structure)

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.

A capacity provider strategy may contain a maximum of 6 capacity providers.

capacityProvider -> (string)

The short name of the capacity provider.

weight -> (integer)

The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can’t be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.

An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that’s run using capacityProviderA , four tasks would use capacityProviderB .

base -> (integer)

The IDs of the subnets associated with the task or service. There’s a limit of 16 subnets that can be specified per AwsVpcConfiguration .

Note

All specified subnets must be from the same VPC.

(string)

Details on a load balancer that are used with a task set.

(structure)

The load balancer configuration to use with a service or task set.

For specific notes and restrictions regarding the use of load balancers with services and task sets, see the CreateService and CreateTaskSet actions.

When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.

We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.

A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .

targetGroupArn -> (string)

The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you’re using a Classic Load Balancer, omit the target group ARN.

For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .

For services using the CODE_DEPLOY deployment controller, you’re required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .

Warning

If your service’s task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

loadBalancerName -> (string)

The name of the load balancer to associate with the Amazon ECS service or task set.

A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

containerName -> (string)

The name of the container (as it appears in a container definition) to associate with the load balancer.

containerPort -> (integer)

The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they’re launched on must allow ingress traffic on the hostPort of the port mapping.

serviceRegistries -> (list)

The details for the service discovery registries to assign to this task set. For more information, see Service discovery .

(structure)

The details for the service registry.

Each service may be associated with one service registry. Multiple service registries for each service are not supported.

When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.

registryArn -> (string)

The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .

port -> (integer)

The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

containerName -> (string)

The container name value to be used for your service discovery service. It’s already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can’t specify both.

containerPort -> (integer)

The port value to be used for your service discovery service. It’s already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can’t specify both.

scale -> (structure)

A floating-point percentage of your desired number of tasks to place and keep running in the task set.

value -> (double)

The value, specified as a percent total of a service’s desiredCount , to scale the task set. Accepted values are numbers between 0 and 100.

unit -> (string)

The unit of measure for the scale value.

stabilityStatus -> (string)

The stability status. This indicates whether the task set has reached a steady state. If the following conditions are met, the task set sre in STEADY_STATE :

  • The task runningCount is equal to the computedDesiredCount .

  • The pendingCount is 0 .

  • There are no tasks that are running on container instances in the DRAINING status.

  • All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.

If any of those conditions aren’t met, the stability status returns STABILIZING .

stabilityStatusAt -> (timestamp)

The Unix timestamp for the time when the task set stability status was retrieved.

tags -> (list)

The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

key -> (string)

One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

value -> (string)

The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

deployments -> (list)

The current state of deployments for the service.

(structure)

The details of an Amazon ECS service deployment. This is used only when a service uses the ECS deployment controller type.

id -> (string)

The ID of the deployment.

status -> (string)

The status of the deployment. The following describes each state.

PRIMARY

The most recent deployment of a service.

ACTIVE

A service deployment that still has running tasks, but are in the process of being replaced with a new PRIMARY deployment.

INACTIVE

A deployment that has been completely replaced.

taskDefinition -> (string)

The most recent task definition that was specified for the tasks in the service to use.

desiredCount -> (integer)

The number of tasks in the deployment that are in the PENDING status.

runningCount -> (integer)

The number of tasks in the deployment that are in the RUNNING status.

failedTasks -> (integer)

The number of consecutively failed tasks in the deployment. A task is considered a failure if the service scheduler can’t launch the task, the task doesn’t transition to a RUNNING state, or if it fails any of its defined health checks and is stopped.

Note

Once a service deployment has one or more successfully running tasks, the failed task count resets to zero and stops being evaluated.

createdAt -> (timestamp)

The Unix timestamp for the time when the service deployment was created.

updatedAt -> (timestamp)

The Unix timestamp for the time when the service deployment was last updated.

capacityProviderStrategy -> (list)

The capacity provider strategy that the deployment is using.

(structure)

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.

A capacity provider strategy may contain a maximum of 6 capacity providers.

capacityProvider -> (string)

The short name of the capacity provider.

weight -> (integer)

The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can’t be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.

An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that’s run using capacityProviderA , four tasks would use capacityProviderB .

base -> (integer)

The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

launchType -> (string)

The launch type the tasks in the service are using. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide .

platformVersion -> (string)

The platform version that your tasks in the service run on. A platform version is only specified for tasks using the Fargate launch type. If one isn’t specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .

platformFamily -> (string)

The operating system that your tasks in the service, or tasks are running on. A platform family is specified only for tasks using the Fargate launch type.

All tasks that run as part of this service must use the same platformFamily value as the service, for example, LINUX. .

networkConfiguration -> (structure)

The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.

awsvpcConfiguration -> (structure)

The VPC subnets and security groups that are associated with a task.

Note

All specified subnets and security groups must be from the same VPC.

subnets -> (list)

The IDs of the subnets associated with the task or service. There’s a limit of 16 subnets that can be specified per AwsVpcConfiguration .

Note

All specified subnets must be from the same VPC.

(string)

securityGroups -> (list)

The IDs of the security groups associated with the task or service. If you don’t specify a security group, the default security group for the VPC is used. There’s a limit of 5 security groups that can be specified per AwsVpcConfiguration .

rolloutState -> (string)

Note

The rolloutState of a service is only returned for services that use the rolling update (ECS ) deployment type that aren’t behind a Classic Load Balancer.

The rollout state of the deployment. When a service deployment is started, it begins in an IN_PROGRESS state. When the service reaches a steady state, the deployment transitions to a COMPLETED state. If the service fails to reach a steady state and circuit breaker is enabled, the deployment transitions to a FAILED state. A deployment in FAILED state doesn’t launch any new tasks. For more information, see DeploymentCircuitBreaker .

rolloutStateReason -> (string)

A description of the rollout state of a deployment.

roleArn -> (string)

The ARN of the IAM role that’s associated with the service. It allows the Amazon ECS container agent to register container instances with an Elastic Load Balancing load balancer.

events -> (list)

The event stream for your service. A maximum of 100 of the latest events are displayed.

(structure)

The details for an event that’s associated with a service.

id -> (string)

The ID string for the event.

createdAt -> (timestamp)

The Unix timestamp for the time when the event was triggered.

message -> (string)

The event message.

createdAt -> (timestamp)

The Unix timestamp for the time when the service was created.

placementConstraints -> (list)

The placement constraints for the tasks in the service.

(structure)

An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide .

Note

If you’re using the Fargate launch type, task placement constraints aren’t supported.

type -> (string)

The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.

expression -> (string)

A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can’t specify an expression if the constraint type is distinctInstance . For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .

placementStrategy -> (list)

The placement strategy that determines how tasks for the service are placed.

(structure)

The task placement strategy for a task or service. For more information, see Task placement strategies in the Amazon Elastic Container Service Developer Guide .

type -> (string)

The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that’s specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.

field -> (string)

The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that’s applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.

networkConfiguration -> (structure)

The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.

awsvpcConfiguration -> (structure)

The VPC subnets and security groups that are associated with a task.

Note

All specified subnets and security groups must be from the same VPC.

subnets -> (list)

The IDs of the subnets associated with the task or service. There’s a limit of 16 subnets that can be specified per AwsVpcConfiguration .

Note

All specified subnets must be from the same VPC.

(string)

securityGroups -> (list)

The IDs of the security groups associated with the task or service. If you don’t specify a security group, the default security group for the VPC is used. There’s a limit of 5 security groups that can be specified per AwsVpcConfiguration .

Note

All specified security groups must be from the same VPC.

(string)

assignPublicIp -> (string)

Whether the task’s elastic network interface receives a public IP address. The default value is DISABLED .

healthCheckGracePeriodSeconds -> (integer)

The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started.

schedulingStrategy -> (string)

The scheduling strategy to use for the service. For more information, see Services .

There are two service scheduler strategies available.

  • REPLICA -The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions.

  • DAEMON -The daemon scheduling strategy deploys exactly one task on each active container instance. This task meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It stop tasks that don’t meet the placement constraints.

Note

Fargate tasks don’t support the DAEMON scheduling strategy.

deploymentController -> (structure)

The deployment controller type the service is using. When using the DescribeServices API, this field is omitted if the service uses the ECS deployment controller type.

type -> (string)

The deployment controller type to use.

There are three deployment controller types available:

ECS

The rolling update (ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration .

CODE_DEPLOY

The blue/green (CODE_DEPLOY ) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.

EXTERNAL

The external (EXTERNAL ) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.

tags -> (list)

The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
