DeregisterTaskDefinition 搭配 AWSSDK 或 CLI 使用

下列程式碼範例示範如何使用 DeregisterTaskDefinition。

動作範例是大型程式的程式碼摘錄,必須在內容中執行。您可以在下列程式碼範例的內容中看到此動作:

CLI
AWS CLI

取消註冊任務定義

下列 deregister-task-definition 範例會取消註冊預設區域中 curler 任務定義的第一個修訂版。

aws ecs deregister-task-definition --task-definition curler:1

請注意,在結果輸出中,任務定義狀態顯示 INACTIVE:

{ "taskDefinition": { "status": "INACTIVE", "family": "curler", "volumes": [], "taskDefinitionArn": "arn:aws:ecs:us-west-2:123456789012:task-definition/curler:1", "containerDefinitions": [ { "environment": [], "name": "curler", "mountPoints": [], "image": "curl:latest", "cpu": 100, "portMappings": [], "entryPoint": [], "memory": 256, "command": [ "curl -v http://example.com/" ], "essential": true, "volumesFrom": [] } ], "revision": 1 } }
