与 Amazon SDK或StartLifecyclePolicyPreview一起使用 CLI

以下代码示例演示如何使用 StartLifecyclePolicyPreview

操作示例是大型程序的代码摘录,必须在上下文中运行。在以下代码示例中,您可以查看此操作的上下文:

CLI
Amazon CLI

创建生命周期策略预览

以下start-lifecycle-policy-preview示例为指定存储库创建由JSON文件定义的生命周期策略预览。

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

policy.json 的内容:

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

输出:

{ "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" }
