在命令协议和容器中使用marathon运行状况检查时的奇怪行为

我不明白为什么下面的请求不能在马拉松中开始健康检查。容器已启动,但状态保持不变 Deploying ```
{
"id": "bridged-webapp",
"cmd": "python3 -m http.server 8080",
"cpus": 0.1,
"mem": 64.0,
"instances": 1,
"container": {
"type": "DOCKER",
"docker": {
"image": "python:3",
"network": "BRIDGE",
"portMappings": [
{
"containerPort": 8080,
"hostPort": 31313,
"servicePort": 9000,
"protocol": "tcp"
}
]
}
},
"healthChecks": [
{
"protocol": "COMMAND",
"command": { "value": "echo 0" },
"maxConsecutiveFailures": 3
}
]
}

当我看马拉松比赛的记录时,它基本上只是说健康检查已经开始了,但仅此而已:

在ui中,作业运行状况为灰色,表示运行状况检查未知。
真正奇怪的是,如果我运行相同的作业,但没有容器,它就可以工作。
有什么想法吗?

更新:原来命令运行状况检查对docker执行器不起作用。。。。一位同事已经为此打开了一个问题:https://github.com/mesosphere/marathon/issues/2140 我们至少会尽快更新文件。
谢谢你发现这个!

看起来在mesos 0.27.0中行为发生了变化。现在 COMMAND 在docker容器内执行。我在任何地方都没看到记录。
