centos7构建https访问的docker私有仓库

测试在局域网机器上测试的，IP为192.168.22.65，以下内容均可替换成自己的机器IP。
测试docker-ce版本：18.09.3-rc1

1. 安装docker环境，并拉取仓库镜像registry
   ①yum install docker-ce
   ②docker pull registry:latest

2. 利用openssl库生成认证证书
   ①mkdir -p ~/certs
   ②编辑/etc/pki/tls/openssl.cnf文件，在[v3_ca]下方添加：
   subjectAltName = IP:192.168.22.65
   ③openssl req -newkey rsa:4096 -nodes -sha256 -keyout ~/certs/192.168.22.65.key -x509 -days 365 -out ~/certs/192.168.22.65.crt
   ④在生成证书过程中填写Common name时，应输入ip地址或域名
   ⑤若第②步和第④步没有按照要求操作，则pull或push时可能会报错如：x509: cannot validate certificate for because it doesn’t contain any IP SANs

3. 将crt证书复制到docker
   ①mkdir /etc/docker/certs.d/192.168.22.65:5000
   ②cp ~/certs/192.168.22.65.crt /etc/docker/certs.d/192.168.22.65:5000/ca.crt

4. 将crt证书复制到本机系统证书管理文件中
   ①cat ~/certs/192.168.22.65.crt >> /etc/pki/tls/certs/ca-bundle.crt
   ②若没有此步骤，可能在pull或push时会报错如：Get https:///v2/: x509: certificate signed by unknown authority

5. 重启docker
   ①systemctl daemon-reload && systemctl restart docker

6. 添加http basic authentication
   ①docker run --entrypoint htpasswd registry:latest -Bbn username password > /opt/registry-var/auth/htpasswd
   ②命令行中username和password分别是登录registry的用户名和密码

7. 运行registry
   ①docker run -d -p 5000:5000 --restart=always --name registry -v /opt/registry-var/auth/:/auth/ -v /opt/registry-var/:/var/lib/registry/ -v ~/certs:/certs -e "REGISTRY_AUTH=htpasswd" -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" -e "REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd" -e "REGISTRY_HTTP_TLS_CERTIFICATE=/certs/192.168.22.65.crt" -e "REGISTRY_HTTP_TLS_KEY=/certs/192.168.22.65.key" registry:latest

8. 查看已运行的registry容器
   ①docker container ls

9. 登录registry
   ①docker login 192.168.22.65:5000

10. pull或push镜像

11. 用idea连接时填写https://192.168.22.65:5000，并填写用户名和密码。
