简介:docker容器化可以使得环境相对独立,减少污染。在遇到关机重启时,重新启动显得很鸡肋,特别是必须开机自启动的程序,添加必要的参数使得每次重启后可以开始使用容器非常有必要。
历史攻略:
centos7.6:安装docker
win10:安装docker和测试安装redis
Ubuntu:安装docker + 设置开机启动
设置开机启动docker:
systemctl enable docker
设置容器自动重启
1、创建容器时设置
docker run -itd --restart=always --name 容器名 使用的镜像:版本
docker 容器的重启策略:
--restart具体参数值详细信息:
no: 默认策略,容器退出时不重启容器;
on-failure: 在容器非正常退出时(退出状态非0)才重新启动容器;
on-failure:3 在容器非正常退出时重启容器,最多重启3次;
always: 无论退出状态是如何,都重启容器;
unless-stopped: 在容器退出时总是重启容器,
但是不考虑在 Docker 守护进程启动时就已经停止了的容器。
2、修改已有容器,通过update设置文章来源:https://www.toymoban.com/news/detail-511693.html
如果创建时未指定 --restart=always,可通过update 命令设置
docker update --restart=always 容器ID(或者容器名)
