docker - 领事观看重要的领事检查

Question

所以我有一个 consul check 来监视一个容器，并设计为在容器停止时变得至关重要。我想创建一个领事 watch ，它将在检查变得关键或几个关键响应之后运行脚本(例如，如果我的检查发送 5 个关键响应，我希望它运行脚本)。

这是用于我的工作检查的 json，以及我对我的 watch 可能是什么样子的猜测:

{

 // this check works
 "checks": [
    {
        "id": "docker_stuff",
        "name": "curl test",
        "notes": "curls the docker container",
        "script": "/scripts/docker.py",
        "interval": "1s"
    }
 ],

 //this watch doesn't work
 "watches": [
    {
        "Node": "client2",
        "CheckID": "docker-stuff",
        "Name": "docker-stuff-watch",
        "Status": "critical",
        "Status_amt": "5",
        "handler": "/scripts/new-docker.sh",
        "Output": "container relaunched",
    }
 ]

}

我需要对 watch 进行哪些更改才能使其正常工作？

我是否还需要使用领事事件来监视我的健康检查，然后触发运行我的 /scripts/new-docker.sh 的领事监视(事件类型)？脚本？如果是这样，那么我将如何进行领事事件来监视我的健康检查？例如，如果这是我的领事检查、监视和事件，我需要更改什么才能使其正常工作？

{
 "checks": [
    {
        "id": "docker_stuff",
        "name": "curl test",
        "notes": "curls the docker container",
        "script": "/scripts/docker.py",
        "interval": "1s"
    }
 ],
 "watches": [
    {     
        "type": "event", 
        "name": "docker-stuff-watch",
        "handler": "/scripts/new-docker.sh"
    }
 ],
 "events": [
    {
        "Node": "client2",
        "CheckID": "docker-stuff",
        "Name": "docker-stuff-event",
        "Status": "critical",
        "Status_amt": "5",
        "Output": "container relaunched",
    }
 ]
}

Answer 1

What do I need to change in my watch to get it working?

有没有错误？确保您的监视处理程序“/scripts/new-docker.sh”正在使用 Consul 将发送的 STDIN，即使它正在将其丢弃到/dev/null，否则该进程将永远等待它被使用

就像是

while read -r -t 0; do read -r; done
