如何检查 Amazon ECS 资源是否正在使用活动任务定义？

解决方法

使用 AWS 命令行界面 (AWS CLI) 确定 Amazon ECS 资源是否使用特定的活动任务定义。然后，使用输出查找并停用不必要的活动任务定义。最佳做法是在删除任务定义之前验证任务定义的状态。

**注意：**如果在运行 AWS CLI 命令时收到错误，请参阅 AWS CLI 错误故障排除。此外，请确保您使用的是最新版本的 AWS CLI。

打开 AWS CLI，然后运行导出命令以设置 region_name 和 task_definition_family 环境占位符。将 example_ 值替换为您的 AWS 区域和任务定义系列的名称：

echo "Listing all task definitions that are in use by ECS resources in your Region $region_name"

for cluster_name in $(aws ecs list-clusters --region $region_name --output json | jq -r '.clusterArns[] | split("/") | .[1]')
do

  for service_name in $(aws ecs list-services --cluster $cluster_name --region $region_name --output json | jq -r '.serviceArns[] | split("/") | .[2]')
  do
    taskdef_arn=$(aws ecs describe-services --cluster $cluster_name --services $service_name --region $region_name --output json | jq -r '.services[].taskDefinition')
    echo "Service Name: $service_name | Task Definition: $taskdef_arn | Cluster: $cluster_name"
  done

  for task_id in $(aws ecs list-tasks --cluster $cluster_name --region $region_name --family $task_definition_family --output json | jq -r '.taskArns[] | split("/") | .[2]')
     do

     result=$(aws ecs describe-tasks --tasks $task_id --cluster $cluster_name --region $region_name --output json)

     task_definition=$(echo $result | jq -r '.tasks[].taskDefinitionArn')

     task_group=$(echo $result | jq -r '.tasks[].group')

     echo "Task ID: $task_id | Group: $task_group | Task Definition: $task_definition | Cluster: $cluster_name"

    done

done

以下示例输出显示了正在使用的任务定义列表：

**可选：**要列出特定区域正在使用的所有任务定义，请从 list-tasks API 调用中删除 --family 选项。使用分页选项列出某个区域的 AWS 账户中的大量任务定义。
