镜像下载
从镜像仓库下载镜像，不指定仓库的地址将默认从Docker Hub官方仓库下载镜像
不指定镜像的tag将下载默认latest镜像
docker pull [OPTIONS] NAME[:TAG|@DIGEST]
从docker官方镜像仓库下载nginx镜像
[root@docker yum.repos.d]# docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx
e6e142a99202: Pull complete
8c317a037432: Pull complete
af2ddac66ed0: Pull complete
Digest: sha256:72c7191585e9b79cde433c89955547685db00f3a8595a750339549f6acef7702
Status: Downloaded newer image for nginx:latest
从指定的镜像仓库192.168.0.180/pan 下载镜像
[root@docker ~]# docker pull 192.168.0.180/pan/pod
Using default tag: latest
latest: Pulling from pan/pod
5a865e48f2fd: Pull complete

Status: Downloaded newer image for 192.168.0.180/pan/pod:latest
下载碰到的问题：
如果私有仓库未开启https连接，docker默认使用https连接镜像仓库将导致无法下载镜像，编辑文件/etc/docker/daemon.json将私有仓库添加为可信任仓库，没有该文件可手动创建
vi /etc/docker/daemon.json
{
"insecure-registries" : ["192.168.0.180"]
}
如果docker版本太低，此方法无用，则编辑/etc/sysconfig/docker文件，添加可信任仓库
vi /etc/sysconfig/docker
INSECURE_REGISTRY='--insecure-registry 192.168.0.180'
镜像操作
查看本地镜像
[root@docker ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx latest c246cd3dd41d 9 days ago 107MB
192.168.0.180/pan/pod latest be92a7c78132 6 weeks ago 205MB
导出本地镜像
镜像下载到本地后存放在分层文件系统中，实用docker save命令可以将其导入到一个普通文件中
[root@docker ~]# docker save -o /root/nginx-img.tar nginx
[root@docker ~]# file /root/nginx-img.tar
/root/nginx-img.tar: POSIX tar archive
[root@docker ~]# ll -h /root/nginx-img.tar
-rw------- 1 root root 107M Jul 2 23:59 /root/nginx-img.tar
导入本地镜像
将导出的镜像文件导入到本地镜像库
[root@docker ~]# docker load --input nginx-img.tar
