start-lifecycle-policy-preview

Description

Starts a preview of a lifecycle policy for the specified repository. This allows you to see the results before associating the lifecycle policy with the repository.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  start-lifecycle-policy-preview
[--registry-id <value>]
--repository-name <value>
[--lifecycle-policy-text <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--registry-id (string)

The Amazon Web Services account ID associated with the registry that contains the repository. If you do not specify a registry, the default registry is assumed.

--repository-name (string)

The name of the repository to be evaluated.

--lifecycle-policy-text (string)

The policy to be evaluated against. If you do not specify a policy, the current policy for the repository is used.

--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 lifecycle policy preview

The following start-lifecycle-policy-preview example creates a lifecycle policy preview defined by a JSON file for the specified repository.

aws ecr start-lifecycle-policy-preview \
    --repository-name "project-a/amazon-ecs-sample" \
    --lifecycle-policy-text "file://policy.json"

Contents of policy.json:

{
   "rules": [
       {
           "rulePriority": 1,
           "description": "Expire images older than 14 days",
           "selection": {
               "tagStatus": "untagged",
               "countType": "sinceImagePushed",
               "countUnit": "days",
               "countNumber": 14
           },
           "action": {
               "type": "expire"
           }
       }
   ]
}

Output:

{
   "registryId": "012345678910",
   "repositoryName": "project-a/amazon-ecs-sample",
   "lifecyclePolicyText": "{\n    \"rules\": [\n        {\n            \"rulePriority\": 1,\n            \"description\": \"Expire images older than 14 days\",\n            \"selection\": {\n                \"tagStatus\": \"untagged\",\n                \"countType\": \"sinceImagePushed\",\n                \"countUnit\": \"days\",\n                \"countNumber\": 14\n            },\n            \"action\": {\n                \"type\": \"expire\"\n            }\n        }\n    ]\n}\n",
   "status": "IN_PROGRESS"
}
