使用 Amazon CLI 命令为 Amazon CloudFormation 创建 Amazon ECS 资源

下面的教程介绍如何使用 Amazon CLI 通过 Amazon CloudFormation 模板创建 Amazon ECS 资源。

  3. 在创建模板文件后，请使用下面的命令创建堆栈。需要 --capabilities 标志才能按照模板中的指定创建 Amazon ECS 任务执行角色。您还可以指定 --parameters 标志来自定义模板参数。

    aws cloudformation create-stack \
      --stack-name ecs-stack \
      --template-body file://ecs-tutorial-template.yaml \
      --capabilities CAPABILITY_IAM

步骤 2：验证资源创建

为确保正确创建资源，请按照下面的步骤进行操作。您还可以检查 Amazon ECS 控制台。

  1. 运行下面的命令列出 Amazon Web Services 区域中的所有任务定义。

    aws ecs list-task-definitions

    该命令返回任务定义 Amazon 资源名称 (ARN) 的列表。您使用模板创建的任务定义的 ARN 将按下面的格式显示。

    {
    "taskDefinitionArns": [
     .....
        "arn:aws:ecs:aws-region:111122223333:task-definition/task-definition-cfn:1",
     .....   
    ]
}

  2. 运行下面的命令列出 Amazon Web Services 区域中的所有集群。

    aws ecs list-clusters

    该命令返回集群 ARN 列表。您使用模板创建的集群的 ARN 将按下面的格式显示。

    {
    "clusterArns": [
        .....
        "arn:aws:ecs:aws-region:111122223333:cluster/CFNCluster",
        .....
    ]
}

  3. 运行下面的命令列出集群 CFNCluster 中的所有服务。

    aws ecs list-services \
      --cluster CFNCluster

    该命令返回服务 ARN 列表。您使用模板创建的服务的 ARN 将按下面的格式显示。

    {
    "serviceArns": [
        "arn:aws:ecs:aws-region:111122223333:service/CFNCluster/cfn-service"
    ]
}

第 3 步：清除

要清理您创建的资源，请运行下面的命令。

aws cloudformation delete-stack \
      --stack-name ecs-stack

delete-stack 命令启动删除本教程中创建的 Amazon CloudFormation 堆栈，从而删除堆栈中的所有资源。要验证删除，您可以重复 步骤 2：验证资源创建 中的过程。输出中的 ARN 列表将不再包含名为 task-definition-cfn 的任务定义或名为 CFNCLuster 的集群。list-services 调用将失败。
