在啟動是指定自動重啟

docker run  --restart=always

修改docker預設配置檔案

# 新增上下面這行
"live-restore": true

docker server配置檔案/etc/docker/daemon.json參考

[[email protected] ~]# cat  /etc/docker/daemon.json 
{
  "registry-mirrors": ["https://registry.docker-cn.com"],
  "graph": "/opt/mydocker", # 修改資料的存放目錄到/opt/mydocker/，原/var/lib/docker/
  "insecure-registries": ["10.0.0.100:5000"],
  "live-restore": true
}
 

重啟生效，只對在此之後啟動的容器生效

[[email protected] ~]# systemctl restart  docker.service
