一: 查看本地镜像
- 命令： docker image list
bash
[root@localhost ~]# docker image list

[root@localhost ~]# 二: 搜索官方镜像
由于国外网站访问不了，我们这里是在国内镜像站搜索镜像
- 命令：docker search 镜像站域名/镜像名
bash
[root@localhost ~]# docker search docker.1ms.run/centos7

[root@localhost ~]# 三: 按星级搜索镜像
按星级搜索镜像，实际上就是在搜索镜像命令的基础上面加上 -f stars=数字 即可
bash
# 这里我们搜索stars大于10的镜像
[root@localhost ~]# docker search docker.1ms.run/centos7 -f stars=10

[root@localhost ~]# 四: 拉取镜像
- 命令：docker pull 镜像名
- 注意：如果镜像名后面不跟版本号，我们默认拉取的是最新的版本号
bash
[root@localhost ~]# docker pull centos:7
7: Pulling from library/centos
2d473b07cdd5: Already exists
Digest: sha256:be65f488b7764ad3638f236b7b515b3678369a5124c47b8d32916d6487418ea4
Status: Downloaded newer image for centos:7
docker.io/library/centos:7
[root@localhost ~]# 五: 查看镜像详情
查看镜像详细信息，需要通过镜像ID，docker image list 可以看到已经下载的本地镜像ID
- 命令：docker image inspect 镜像ID
bash
[root@localhost ~]# docker image list

],六: 删除镜像
命令：
- 删除镜像：docker rmi 镜像id
- 强制删除：在最后加上 --force
- 删除所有镜像：docker rmi $(docker images -q)
- 查看镜像id： docker images -q
bash
# 删除单个镜像
[root@localhost ~]# docker image list

[root@localhost ~]# 七: 给镜像打tag
给已有的镜像添加一个新的 "标签（tag）"，相当于给镜像起一个 "别名"。
- 命令： docker tag 源镜像名 新起的镜像名
bash
[root@localhost ~]# docker tag centos:5 centos:5.1
[root@localhost ~]# docker image list
