How to start a docker container automatically after booting

When using docker run to start the container, use the --restart parameter to set:

docker run -m 512m --memory-swap 1G -it -p 6379:6379 --restart=always --name redis -d redis

--restart The specific parameter value details are as follows:

no - 容器退出时，不重启容器
on-failure - 只有在非0状态退出时才从新启动容器
always - 无论退出状态是如何，都重启容器

You can also specify the maximum number of times Docker will try to restart the container when using the on-failure policy.

By default, Docker will try to restart the container forever.

sudo docker run --restart=on-failure:10 redis

If --restart=always is not specified when creating, you can use the update command

docker update --restart=always xxx
