设置docker开机自启

systemctl enable docker

设置容器自启

1. 创建容器时设置：

docker run -d --restart=always --name 容器名称 镜像名称
# 例如：
docker  run --restart=always 56f0b18af626

2. 更新已有容器设置：

docker update --restart=always 容器ID
# 例如：
docker  update --restart=always 56f0b18af626

–restart具体参数,详见官方文档说明

Policy	Result
no	Do not automatically restart the container when it exits. This is the default. 默认设置,容器退出时不重启容器。
on-failure[:max-retries]	Restart only if the container exits with a non-zero exit status. Optionally, limit the number of restart retries the Docker daemon attempts. 在容器非正常退出时重启容器，最多重启max-retries次。
always	Always restart the container regardless of the exit status. When you specify always, the Docker daemon will try to restart the container indefinitely. The container will also always start on daemon startup, regardless of the current state of the container. 总是重启容器。
unless-stopped	Always restart the container regardless of the exit status, including on daemon startup, except if the container was put into a stopped state before the Docker daemon was stopped. 总是重启容器，除非在Docker守护程序停止之前容器就处于停止状态。
