If you do not have a Docker ID, head over to https://hub.docker.com to create one. Username (dangerwolf): dangerwolf Password: Login Succeeded 依次输入用户名和密码后(每次输入均以回车键确认)可完成登录。 ## 给image打tag ~~~ docker tag 135ef118c2b9 dangerwolf/showdoc:latest ~~~ ``` docker tag [imageId] [imageName] ``` tag后面的参数依次为镜像ID、用户名或者组织名、仓库名和版本。 ## 提交image ~~~ docker push dangerwolf/showdoc ~~~ # 常用的管理工具 ## Kitematic 官方推荐的一款管理工具 ~~~ https://kitematic.com/ ~~~
