怎么实现Docker私有仓库Registry 搭建

怎么实现Docker私有仓库Registry 搭建，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

#==>域名或主机名

signdomain=a.b.cn

#==>生成SSL证书

mkdir ~/certs

openssl req -nodes -subj "/C=CN/ST=ZheJiang/L=HangZhou/CN=$signdomain" -newkey rsa:4096 -keyout ~/certs/$signdomain.key -out ~/certs/$signdomain.csr

openssl x509 -req -days 3650 -in ~/certs/$signdomain.csr -signkey ~/certs/$signdomain.key -out ~/certs/$signdomain.crt

#==>运行docker registry v2

docker run -d -p 5000:5000 --restart=always --name registry \  -v ~/certs:/certs \  -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/$signdomain.crt \  -e REGISTRY_HTTP_TLS_KEY=/certs/$signdomain.key \  registry:2

#==>尝试 push 镜像

docker tag ubuntu a.b.cn:5000/ubuntu

docker push a.b.cn:5000/ubuntu

#==>出现如下错误:

The push refers to a repository [a.b.cn:5000/ubuntu] (len: 1)

unable to ping registry endpoint https://a.b.cn:5000/v0/

v2 ping attempt failed with error: Get https://a.b.cn:5000/v2/: x509: certificate signed by unknown authority

v1 ping attempt failed with error: Get https://a.b.cn:5000/v1/_ping: x509: certificate signed by unknown authority

#==>错误是由于没有权威认证的自签名证书引起，在将crt复制docker Damon 的节点上如下目录（以当前节点示例，其它节点类似 scp 过去）：

mkdir /etc/docker/certs.d/$signdomain:5000

cp ~/certs/$signdomain.crt /etc/docker/certs.d/$signdomain:5000/ca.crt

#==>验证 pull 和 push

docker pull a.b.cn:5000/ubuntu

整体：

#导入registry v2 镜像包sudo docker load < registry.2.tar#设置registry所在主机域名或主机名signdomain=docker-1#设置registry认证文件目录sudo mkdir ~/certs#openssl生成认证文件sudo openssl req -nodes -subj "/C=CN/ST=ZheJiang/L=HangZhou/CN=$signdomain" -newkey rsa:4096 -keyout ~/certs/$signdomain.key -out ~/certs/$signdomain.csrsudo openssl x509 -req -days 3650 -in ~/certs/$signdomain.csr -signkey ~/certs/$signdomain.key -out ~/certs/$signdomain.crt#运行registry容器sudo docker run -d -p 5000:5000 --name registry -v ~/certs:/certs -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/$signdomain.crt -e REGISTRY_HTTP_TLS_KEY=/certs/$signdomain.key registry:2#将crt文件复制到各docker Damon所在主机的/etc/docker/cert.d/$signdomain:5000目录(不存在先新建)sudo mkdir /etc/docker/certs.d/sudo mkdir /etc/docker/certs.d/$signdomain:5000sudo cp ~/certs/$signdomain.crt /etc/docker/certs.d/$signdomain:5000/ca.crt#测试registry服务sudo docker tag registry:2 docker-1:5000/registry:2sudo docker push docker-1:5000/registry:2
