describe-auto-scaling-configuration¶

Description¶

Return a full description of an App Runner automatic scaling configuration resource.

Synopsis¶

  describe-auto-scaling-configuration
--auto-scaling-configuration-arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--auto-scaling-configuration-arn (string)

The Amazon Resource Name (ARN) of the App Runner auto scaling configuration that you want a description for.

The ARN can be a full auto scaling configuration ARN, or a partial ARN ending with either ``…/name `` or ``…/name /revision `` . If a revision isn’t specified, the latest active revision is described.

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To describe the latest active revision of an auto scaling configuration

The following describe-auto-scaling-configuration example gets a description of the latest active revision of an App Runner auto scaling configuration. To describe the latest active revision, specify an ARN that ends with the configuration name, without the revision component.

In the example, two revisions exist. Therefore, revision 2 (the latest) is described. The resulting object shows "Latest": true.

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

Contents of input.json:

{
    "AutoScalingConfigurationArn": "arn:aws:apprunner:us-east-1:123456789012:autoscalingconfiguration/high-availability"
}

Output:

{
    "AutoScalingConfiguration": {
        "AutoScalingConfigurationArn": "arn:aws:apprunner:us-east-1:123456789012:autoscalingconfiguration/high-availability/2/e76562f50d78042e819fead0f59672e6",
        "AutoScalingConfigurationName": "high-availability",
        "AutoScalingConfigurationRevision": 2,
        "CreatedAt": "2021-02-25T17:42:59Z",
        "Latest": true,
        "Status": "ACTIVE",
        "MaxConcurrency": 30,
        "MaxSize": 90,
        "MinSize": 5
    }
}

Example 2: To describe a specific revision of an auto scaling configuration

The following describe-auto-scaling-configuration example get a description of a specific revision of an App Runner auto scaling configuration. To describe a specific revision, specify an ARN that includes the revision number.

In the example, several revisions exist and revision 1 is queried. The resulting object shows "Latest": false.

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

Contents of input.json:

{
    "AutoScalingConfigurationArn": "arn:aws:apprunner:us-east-1:123456789012:autoscalingconfiguration/high-availability/1"
}

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": false,
        "Status": "ACTIVE",
        "MaxConcurrency": 100,
        "MaxSize": 50,
        "MinSize": 5
    }
}

Output¶

AutoScalingConfiguration -> (structure)

A full description of the App Runner auto scaling configuration that you specified in 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.
