拉取镜像

docker pull [OPTION] NAME[:TAG]-a --all-tags=false 下载仓库中所有标记的镜像eggyer@ubuntu:/usr/local$ docker pull ubuntu:14.0414.04: Pulling from library/ubuntu07235cd0e105: Downloading [=====>                                             ] 7.024 MB/65.7 MB751bed4a496a: Download complete 1b389da167c9: Download complete cd4d9b716097: Download complete 2bb47aeaf95f: Download complete d267439203ef: Download complete 

使用–registry-mirror选项

从前面的测试中可以发现,从docker官网拉取镜像过程很慢

1. 修改/etc/default/docker
2. DOCKER_OPTS=”–registry-mirror=http://MIRROR-ADDR”

推送镜像

注意要把推送镜像名改为 用户名/xxx的形式不然会出现You cannot push a “root” repository. Please rename your repository to / (ex: eggyer/ubuntu16.04)
