docker 构建 https 私有仓库 Registry

1.安装docker

# docker install docker

2.拉取仓库镜像

# docker pull registry

3.生成认证certificate

# mkdir ~/certs
# openssl req -newkey rsa:4096 -nodes -sha256 -keyout /root/certs/domain.key  -x509 -days 365 -out /root/certs/domain.crt

4.复制认证到docker

# mkdir /etc/docker/certs.d/mydockerhub.com:5000
# cp /root/certs/domain.crt  /etc/docker/certs.d/mydockerhub.com:5000/ca.crt

5.复制认证到本机

# cat /root/certs/domain.crt >> /etc/pki/tls/certs/ca-bundle.crt 

7.启动仓库镜像

# docker run -d -p 5000:5000 --privileged=true -v /root/docker/registry:/var/lib/registry -v /root/certs/:/root/certs  -e REGISTRY_HTTP_TLS_CERTIFICATE=/root/cer
ts/domain.crt -e REGISTRY_HTTP_TLS_KEY=/root/certs/domain.key registry

8.创建一个镜像

docker run -it --name=nginx centos /bin/bash
yum install epel-release.noarch -y
yum install nginx -y
docker commit 7ab4d6b6a438 dingyingsi/nginx  //7ab4d6b6a438为容器id
docker tag dingyingsi/nginx mydockerhub.com:5000/nginx:latest //给当前镜像打标签

9.修改当前主机名：

vi /etc/hosts
192.168.184.166 mydockerhub.com

10.推送镜像到https私有仓库

docker push mydockerhub.com:5000/nginx

11.删除本地镜像并重新从https私有仓库拉取镜像

docker rmi mydockerhub.com:5000/nginx
docker pull mydockerhub.com:5000/nginx

 12.添加http basic authentication

docker run --entrypoint htpasswd  registry:2 -Bbn testuser testpassword > /root/auth/htpasswd

13.停止仓库

docker stop  2a4c76559e18
docker start 2a4c76559e18

14.启动http basic authentication仓库

docker run -d 
--name registry 
-p 5000:5000 
--restart=always 
--privileged=true 
-v /root/docker/registry:/var/lib/registry 
-e "REGISTRY_AUTH=htpasswd" 
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" 
-v /root/auth:/root/auth 
-e "REGISTRY_AUTH_HTPASSWD_PATH=/root/auth/htpasswd" 
-v /root/certs/:/root/certs 
-e REGISTRY_HTTP_TLS_CERTIFICATE=/root/certs/domain.crt 
-e REGISTRY_HTTP_TLS_KEY=/root/certs/domain.key 
registry

15.登录仓库

docker login mydockerhub.com:5000
username:testuser
password:testpassword

16.其他服务器用这个私有仓库，直接复制docker的仓库服务器下的/etc/docker/cert.d/下的mydockerhub.com:5000/ca.cert目录和文件，到自己的/etc/docker/cert.d/目录下即可。
