docker镜像仓库
搭建私有镜像仓库
Docker Hub作为Docker默认官方公共镜像，如果想自己搭建私有镜像仓库，官方也提供registry镜像，使得搭建私有仓库非常简单。
下载registry镜像并启动
[root@docker ~]# docker pull registry
[root@docker ~]# docker run -d -v /opt/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry

测试查看镜像仓库中所有镜像
[root@docker ~]# curl http://192.168.193.128:5000/v2/_catalog
{"repositories":[]}
私有镜像仓库管理
配置私有仓库可信任
[root@docker ~]# cat /etc/docker/daemon.json
{
"registry-mirrors":["https://registry.docker-cn.com"],
"insecure-registries":["192.168.193.128：5000"]
}
[root@docker ~]# systemctl restart docker
打标签
[root@docker ~]# docker tag nginx:1.12 192.168.193.128:5000/nginx:1.12
上传
[root@docker ~]# docker push 192.168.193.128:5000/nginx:1.12
[root@docker ~]# curl http://192.168.193.128:5000/v2/_catalog
{"repositories":["nginx"]}
查看信息
[root@docker ~]# curl http://192.168.193.128:5000/v2/nginx/tags/list
{"name":"nginx","tags":["1.12"]}
下载
[root@docker ~]# docker run -itd --name nginx -p 80:80 192.168.193.128:5000/nginx:1.12

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

Harbor安装与配置
[root@docker ssl]# cd ..
[root@docker harbor]# ls
harbor.v1.8.1.tar.gz harbor.yml install.sh LICENSE prepare ssl
配置harbor.cfg（新版已经改成harbor.yml）
修改配置，协议，证书，管理员密码
示例：
hostname = reg.goldenyin.com
将http:和port:80注释（新版本）
ui_url_protocol = https（新版无此项）
ssl_cert = ./ssl/reg.lvusyy.com.crt（新版本certificate: ./ssl/reg.goldenyin.com.crt）
ssl_cert_key = ./ssl/reg.lvusyy.com.key（新版本private_key: ./ssl/reg.goldenyin.com.key）
harbor_admin_password = harbor12345
[root@docker harbor]# ./prepare （读取配置文件，新版本无需此步骤操作）
将https:和port:443注释取消（新版本）
external_url: https://reg.goldenyin.com:8433（新版本）
[root@docker harbor]# ./install.sh
✔ ----Harbor has been installed and started successfully.----
Now you should be able to visit the admin portal at http://reg.goldenyin.com.
