4.Docker常用命令
查看docker镜像
docker images
查看节点信息
docker node ls
查看已存在的容器
docker ps
运行镜像
docker run -d -P 8000:80 nginx
把镜像制作成容器并映射端口（物理:docker）
docker run -itd -p 82:80 --name 容器名 镜像名 /bin/bash
进入已存在的docker容器
docker exec -i -t 容器名 /bin/bash
后台运行docker：
进入docker后按快捷键Ctrl + P + Q 即可后台运行
删除docker CONTAINER （docker ps 查看）
docker rm $CONTAINER ID
修改docker tag
docker tag IMAGEID(镜像id) REPOSITORY:TAG（仓库：标签） #例子 docker tag ca1b6b825289 registry.cn-hangzhou.aliyuncs.com/xxxxxxx:v1.0
在Docker Swarm集群中，在删除Docker集群节点后，集群中该节点仍然存在，但是状态显示为Down， 需要在Swarm的Manager节点执行以下命令， 删除已经移除的Worker节点：
[root@centos7-Master ~]# docker node rm --force 4ukr7ghj4iuvb89gu0g5ok1d
5.启动时故障排错
查看服务ID
sudo docker service ls
查看服务状态详细信息
sudo docker service ps --no-trunc jrcg61useki27zobod1ftozzw
查看docker日志信息
sudo docker service logs jrcg61useki27zobod1ftozzw
6.docker备份恢复容器
备份docker 容器
docker export -o update.tar 容器ID
导入备份的docker容器
docker import - update < update.tar
导入后作为镜像存在
然后从镜像启动容器
docker run -itd -p 82:80 --name 容器名 镜像名 /bin/bash
7.docker备份恢复镜
1）查看镜像ID
docker images
2）备份镜像
docker save -o web.tar 镜像ID
3）恢复镜像
docker load -i web.tar
4）作为容器运行镜像
docker run -d -p 8000:80 镜像名
5）查看运行的容器
docker ps -a
