标签(tag)

简介

将一个已经的镜像打标签，此会升成另外一个新的镜像

使用示例

$ docker image ls | grep mysql
mysql                     latest              8d65ec712c69        8 days ago          445MB
$ docker tag mysql mysql-tag
$ docker image ls | grep mysql
mysql-tag                 latest              8d65ec712c69        8 days ago          445MB
mysql                     latest              8d65ec712c69        8 days ago          445MB

把本地镜像标签为远程仓库认可的标准形式，然后推送到远程仓库

$ docker tag friendlyhello hongxingwz/get-started3

$ docker image ls | grep started3
hongxingwz/get-started3   latest              6066a516d5c9        About an hour ago   156MB

$ docker push hongxingwz/get-started3
The push refers to repository [docker.io/hongxingwz/get-started3]
