【问题描述】:
我正在一个 ECS 集群上运行一个 Docker 镜像,以便在其中运行一些简单的测试。但是,当我运行它时:
aws ecs execute-command \
--cluster MyEcsCluster \
--task $ECS_TASK_ARN \
--container MainContainer \
--command "/bin/bash" \
--interactive
我得到错误:
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+代理都在运行:
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": [

"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,
})
