create-auto-scaling-configuration

Description

Create an App Runner automatic scaling configuration resource. App Runner requires this resource when you create or update App Runner services and you require non-default auto scaling settings. You can share an auto scaling configuration across multiple services.

Create multiple revisions of a configuration by calling this action multiple times using the same AutoScalingConfigurationName . The call returns incremental AutoScalingConfigurationRevision values. When you create a service and configure an auto scaling configuration resource, the service uses the latest active revision of the auto scaling configuration by default. You can optionally configure the service to use a specific revision.

Configure a higher MinSize to increase the spread of your App Runner service over more Availability Zones in the Amazon Web Services Region. The tradeoff is a higher minimal cost.

Configure a lower MaxSize to control your cost. The tradeoff is lower responsiveness during peak demand.

[--max-concurrency <value>]

Options

--auto-scaling-configuration-name (string)

A name for the auto scaling configuration. When you use it for the first time in an Amazon Web Services Region, App Runner creates revision number 1 of this name. When you use the same name in subsequent calls, App Runner creates incremental revisions of the configuration.

Note

The name DefaultConfiguration is reserved (it’s the configuration that App Runner uses if you don’t provide a custome one). You can’t use it to create a new auto scaling configuration, and you can’t create a revision of it.

When you want to use your own auto scaling configuration for your App Runner service, create a configuration with a different name , and then provide it when you create or update your service.

--max-concurrency (integer)

The maximum number of concurrent requests that you want an instance to process. If the number of concurrent requests exceeds this limit, App Runner scales up your service.

Default: 100

--min-size (integer)

The minimum number of instances that App Runner provisions for your service. The service always has at least MinSize provisioned instances. Some of them actively serve traffic. The rest of them (provisioned and inactive instances) are a cost-effective compute capacity reserve and are ready to be quickly activated. You pay for memory usage of all the provisioned instances. You pay for CPU usage of only the active subset.

App Runner temporarily doubles the number of provisioned instances during deployments, to maintain the same capacity for both old and new code.

Default: 1

--max-size (integer)

The maximum number of instances that your service scales up to. At most MaxSize instances actively serve traffic for your service.

Default: 25

--tags (list)

A list of metadata items that you can associate with your auto scaling configuration resource. A tag is a key-value pair.

(structure)

Describes a tag that is applied to an App Runner resource. A tag is a metadata item consisting of a key-value pair.

Key -> (string)

The key of the tag.

Value -> (string)

The value of the tag.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--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 create a high availability auto scaling configuration

The following create-auto-scaling-configuration example creates an auto scaling configuration optimized for high availability by setting MinSize to 5. With this configuration, App Runner attempts to spread your service instances over the most Availability Zones possible, up to five, depending on the AWS Region.

The call returns an AutoScalingConfiguration object with the other settings set to their defaults. In the example, this is the first call to create a configuration named high-availability. The revision is set to 1, and it’s the latest revision.

aws apprunner create-auto-scaling-configuration \
    --cli-input-json file://input.json

Contents of input.json:

{
    "AutoScalingConfigurationName": "high-availability",
    "MinSize": 5
}

Output:

{
    "AutoScalingConfiguration": {
        "AutoScalingConfigurationArn": "arn:aws:apprunner:us-east-1:123456789012:autoscalingconfiguration/high-availability/1/2f50e7656d7819fead0f59672e68042e",
        "AutoScalingConfigurationName": "high-availability",
        "AutoScalingConfigurationRevision": 1,
        "CreatedAt": "2020-11-03T00:29:17Z",
        "Latest": true,
        "Status": "ACTIVE",
        "MaxConcurrency": 100,
        "MaxSize": 50,
        "MinSize": 5
    }
}

Output

AutoScalingConfiguration -> (structure)

A description of the App Runner auto scaling configuration that’s created by this request.

AutoScalingConfigurationArn -> (string)

The Amazon Resource Name (ARN) of this auto scaling configuration.

AutoScalingConfigurationName -> (string)

The customer-provided auto scaling configuration name. It can be used in multiple revisions of a configuration.

AutoScalingConfigurationRevision -> (integer)

The revision of this auto scaling configuration. It’s unique among all the active configurations ("Status": "ACTIVE" ) that share the same AutoScalingConfigurationName .

Latest -> (boolean)

It’s set to true for the configuration with the highest Revision among all configurations that share the same AutoScalingConfigurationName . It’s set to false otherwise.

Status -> (string)

The current state of the auto scaling configuration. If the status of a configuration revision is INACTIVE , it was deleted and can’t be used. Inactive configuration revisions are permanently removed some time after they are deleted.

MaxConcurrency -> (integer)

The maximum number of concurrent requests that an instance processes. If the number of concurrent requests exceeds this limit, App Runner scales the service up.

MinSize -> (integer)

The minimum number of instances that App Runner provisions for a service. The service always has at least MinSize provisioned instances. Some of them actively serve traffic. The rest of them (provisioned and inactive instances) are a cost-effective compute capacity reserve and are ready to be quickly activated. You pay for memory usage of all the provisioned instances. You pay for CPU usage of only the active subset.

App Runner temporarily doubles the number of provisioned instances during deployments, to maintain the same capacity for both old and new code.

MaxSize -> (integer)

The maximum number of instances that a service scales up to. At most MaxSize instances actively serve traffic for your service.

CreatedAt -> (timestamp)

The time when the auto scaling configuration was created. It’s in Unix time stamp format.

DeletedAt -> (timestamp)

The time when the auto scaling configuration was deleted. It’s in Unix time stamp format.
