[root@docker03 ~]# docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx
000eee12ec04: Pull complete

3.docker push （上传镜像）

[root@docker03 ~]# docker push nginx

4.docker images （查看本地已有镜像）

[root@docker03 ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest              231d40e811cd        2 weeks ago         126MB

5.docker rmi （删除镜像）

[root@docker03 ~]# docker rmi nginx:latest 
Untagged: nginx:latest
Untagged: nginx@sha256:50cf965a6e08ec5784009d0fccb380fc479826b6e0e65684d9879170a9df8566
Deleted: sha256:231d40e811cd970168fb0c4770f2161aa30b9ba6fe8e68527504df69643aa145

6.docker tag（给镜像打标签)

[root@docker03 ~]# docker tag nginx:latest nginx:v1

7.docker load -i docker_kod.tar.gz (本地镜像导入)

[root@docker03 ~/docker]# ls
docker_kod.tar.gz
[root@docker03 ~/docker]# 
[root@docker03 ~/docker]# docker load -i docker_kod.tar.gz 
b5e11aae8a8e: Loading layer [==================================================>]  202.9MB/202.9MB

8.docker import (导入镜像，images没有镜像名和标签)

[root@docker03 ~/docker]# docker import docker_kod.tar.gz 
[root@docker03 ~/docker]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
<none>              <none>              c1863e2b0717        35 seconds ago      627MB

9.docker save(保存镜像到当前目录)

[root@docker03 ~/docker]# docker save nginx:latest  -o docker_nginx.tar.gz

10.docker inspect nginx:v1 (查看镜像属性)

[root@docker03 ~/docker]# docker inspect nginx:v1 

11.docker image prune（清理无人使用的镜像和拉取到一半的镜像，删除镜像缓存）

[root@docker03 ~/docker]# docker image prune 
WARNING! This will remove all dangling images.
Are you sure you want to continue? [y/N] y
Deleted Images:
deleted: sha256:c1863e2b07171e582113544e6c19660cd3fee7d6f1d89401529f8472732c8e33

[root@22732407347e /]# /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime 

13.删除<none>镜像

[root@docker03 ~]# docker image prune
