Docker运维与实战（一）-Docker的前世今生

1、登录远端仓库

$ docker login 10.12.1.202:8088
Username: zhangzhixiang
Password: 
Login Succeeded

2、打标签

$ docker tag hello-world daocloud.io/oascloud/hello-world:v1
chenyangdeMacBook-Pro:~ chenyang$ docker images
REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE
hello-world                    latest              fce289e99eb9        9 weeks ago         1.84 kB
hello-world                    v1                  fce289e99eb9        9 weeks ago         1.84 kB
hello-world                    v2                  fce289e99eb9        9 weeks ago         1.84 kB

3、推送镜像到远端仓库

$ docker push daocloud.io/oascloud/hello-world:v1
The push refers to a repository [daocloud.io/zter/hello-world]
