设置容器自动重启方法
创建容器的时候设置自动重启
- 创建容器命令：docker run -d --name=容器名称 -p 宿主机端口号:容器端口号 -v 宿主机目录:容器目录
--restart=always镜像名称
--restart参数详解： no //默认参数，容器退出时不重启 on-failure //容器非正常退出则重启容器（退出状态非0则表示非正常退出） on-failure:2 //容器非正常退出时重启容器，最多重启2次（次数自己配置） always //只要容器退出都自动重启容器，不限制退出状态 unless-stopped //在容器退出时总是重启容器，排除在Docker进程启动时就已经停止运行的容器- 创建容器命令：docker run -d --name=容器名称 -p 宿主机端口号:容器端口号 -v 宿主机目录:容器目录
修改已有容器设置
- 创建容器命令：docker run -d --name=容器名称 -p 宿主机端口号:容器端口号 -v 宿主机目录:容器目录 镜像名称
修改容器配置命令：
docker update --restart=always 容器名称/容器ID*为了方便，一般使用容器名称C:\Users\Shinelon>docker update --restart=always mynginx mynginx
查询容器重启策略的方法
使用
docker inspect mynginx命令查询容器详细信息，然后找到HostConfig下的RestartPolicy就可以看到容器的重启策略C:\Users\Shinelon>docker inspect mynginx [ { "Id": "63e104fde8b195f24b11728e55034cd6173fad8ee60053daac9bbcbe671a9fc3",
