`aws ecs execute-command` 导致 `TargetNotConnectedException` `执行命令因内部错误而失败`

Question

我正在运行将 ECS 集群上的 Docker 图像 shell 放入其中，并运行一些简单的测试。然而，当我运行这个：

aws ecs execute-command  \
  --cluster MyEcsCluster \
  --task $ECS_TASK_ARN \
  --container MainContainer \
  --command "/bin/bash" \
  --interactive

我收到错误：

The Session Manager plugin was installed successfully. Use the AWS CLI to start a session.


An error occurred (TargetNotConnectedException) when calling the ExecuteCommand operation: The execute command failed due to an internal error. Try again later.

我可以确认任务+容器+代理都是运行ning:

aws ecs describe-tasks \
  --cluster MyEcsCluster \
  --tasks $ECS_TASK_ARN \
  | jq '.'

      "containers": [
        {
          "containerArn": "<redacted>",
          "taskArn": "<redacted>",
          "name": "MainContainer",
          "image": "confluentinc/cp-kafkacat",
          "runtimeId": "<redacted>",
          "lastStatus": "RUNNING",
          "networkBindings": [],
          "networkInterfaces": [
            {
              "attachmentId": "<redacted>",
              "privateIpv4Address": "<redacted>"
            }
          ],
          "healthStatus": "UNKNOWN",
          "managedAgents": [
            {
              "lastStartedAt": "2021-09-20T16:26:44.540000-05:00",
              "name": "ExecuteCommandAgent",
              "lastStatus": "RUNNING"
            }
          ],
          "cpu": "0",
          "memory": "4096"
        }
      ],

我正在使用 CDK Typescript 代码定义 ECS 集群和任务定义：

    new Cluster(stack, `MyEcsCluster`, {
        vpc,
        clusterName: `MyEcsCluster`,
    })

    const taskDefinition = new FargateTaskDefinition(stack, TestTaskDefinition`, {
        family: `TestTaskDefinition`,
        cpu: 512,
        memoryLimitMiB: 4096,
    })
    taskDefinition.addContainer("MainContainer", {
        image: ContainerImage.fromRegistry("confluentinc/cp-kafkacat"),
        command: ["tail", "-F", "/dev/null"],
        memoryLimitMiB: 4096,
        // Some internet searches suggested setting this flag. This didn't seem to help.
        readonlyRootFilesystem: false,
    })
