根据运行状况检查重启不健康的Docker容器 [英] Restarting an unhealthy docker container based on healthcheck

问题描述

我正在使用 Docker 17.09.0-ce 版本，并且我看到容器被标记为不健康。是否可以选择重新启动容器而不是使容器保持不正常状态？

I am using Docker version 17.09.0-ce, and I see that containers are marked as unhealthy. Is there an option to get the container restart instead of keeping the container as unhealthy?

推荐答案

重新启动不健康容器功能已在原始PR（ https://github.com/moby/moby/pull/22719 ） ，但经过讨论后被删除，并认为稍后将作为RestartPolicy的增强。

Restarting of unhealty container feature was in the original PR (https://github.com/moby/moby/pull/22719), but was removed after a discussion and considered to be done later as enhancement of RestartPolicy.

此刻，您可以使用以下解决方法自动重启不健康的容器： https://hub.docker.com/r/willfarrell/autoheal/

At this moment you can use this workaround to automatically restarting unhealty containers: https://hub.docker.com/r/willfarrell/autoheal/

以下是示例撰写文件：

version: '2'
services:
  autoheal:
    restart: always
    image: willfarrell/autoheal
    environment:
      - AUTOHEAL_CONTAINER_LABEL=all
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

只需对此执行 docker-compose up -d
