docker构建私有仓库并设置仓库用户和密码

一、docker构建私有仓库

#搭建私有镜像仓库
[root@docker_test opt]# docker pull registry
Using default tag: latest
latest: Pulling from library/registry
Get https://registry-1.docker.io/v2/library/registry/manifests/sha256:b1165286043f2745f45ea637873d61939bff6d9a59f76539d6228abf79f87774: net/http: TLS handshake timeout

#查看镜像
[root@docker_test opt]# docker images
