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 tag使用镜像tag重命名

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
chenyangdeMacBook-Pro:~ chenyang$ docker tag hello-world:latest hello-world:v2
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

使用docker push 推送镜像到daocloud.io

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$

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]
