docker tag 详解

docker tag 命令的使用，以及如何将本地的镜像推送到daocloud.io，这里不用docker hub作实验，是因为，docker hub网速不给力，容易推送失败。

使用docker tag使用镜像ID重命名

chenyangdeMacBook-Pro:~ chenyang$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
hello-world         latest              fce289e99eb9        9 weeks ago         1.84 kB
chenyangdeMacBook-Pro:~ chenyang$ 


chenyangdeMacBook-Pro:~ chenyang$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
hello-world         latest              fce289e99eb9        9 weeks ago         1.84 kB
chenyangdeMacBook-Pro:~ chenyang$ docker tag fce289e99 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

使用docker push 推送镜像到daocloud.io

1. 需要登陆daocloud.io,如果没有账户的，需要去网站上注册一个。

   chenyangdeMacBook-Pro:~ chenyang$ docker login daocloud.io
   Username (chenyang_1010): chenyang_1010
   Password:
   Login Succeeded
   chenyangdeMacBook-Pro:~ chenyang$

2. 打上标签，然后上传

   chenyangdeMacBook-Pro:~ chenyang$ docker tag hello-world daocloud.io/zter/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
   daocloud.io/zter/hello-world v1 fce289e99eb9 9 weeks ago 1.84 kB
   chenyangdeMacBook-Pro:~ chenyang$ docker push daocloud.io/zter/hello-world:v1
   The push refers to a repository [daocloud.io/zter/hello-world]
