今天尝试下载docker镜像时候提示
1Error response from daemon: pull access denied for gitea, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
大概意思就是不登录，不让下载镜像，或是你的镜像文件名不对。 好吧，注册一个吧。
1.访问DockerHub注册账户 2.本地登陆账户
1docker login -u用户名 -p
3.ok，请注意你的密码貌似是明文保存在本地的。
