2.docker-镜像命令

目录

2.查看前5个

3.拉取镜像,没有tag就是最新版本

4.查看镜像/容器/数据卷所占空间

5.删除镜像

6.镜像分层

7.虚悬镜像

8.如果build时出现CACHED失败

---

1.列出本机的镜像

docker images -aq

2.查看前5个

docker search --limit5 redis

3.拉取镜像,没有tag就是最新版本

docker pull redis:[tag]

4.查看镜像/容器/数据卷所占空间

docker system df

5.删除镜像

单个删除 docker rmi -f  镜像ID

多个删除 docker rmi -f 镜像名称1:tag 镜像名称2:tag

全部删除 docker rmi -f $(docker images -qa)

6.镜像分层

docker commit -d="描述" -a="作者" 容器id 镜像名称:版本

7.虚悬镜像

查看  docker image ls -f dangling=true

删除 docker image prune

8.如果build时出现CACHED失败
