安装docker

yum install docker

 

启动docker

systemctl start docker

 

拉取registry镜像

docker pull registry

 

创建仓库配置文件/etc/docker/registry/config.yml，文件内容如下：

version: 0.1log:  fields:    service: registrystorage:  delete:    enabled: true  cache:    blobdescriptor: inmemory  filesystem:    rootdirectory: /var/lib/registryhttp:  addr: :5000  headers:    X-Content-Type-Options: [nosniff]health:  storagedriver:    enabled: true    interval: 10s    threshold: 3

 

启动registry

docker run -d --name registry -p 5000:5000 -v /var/lib/registry:/var/lib/registry -v /etc/docker/registry/config.yml:/etc/docker/registry/config.yml registry

 

执行docker pull或者docker push的时候可能会提示以下错误：

server gave HTTP response to HTTPS client

原因是客户端采用https，而docker registry未采用https服务所致

解决方法：

修改docker客户端的systemd文件

centos系统：/usr/lib/systemd/system/docker.serviceubuntu系统：/lib/systemd/system/docker.service

 

找到ExecStart这行，增加这段内容：

--insecure-registry 1.2.3.4:5000

其中，1.2.3.4是docker仓库地址

重启启动docker服务

systemctl daemon-reloadsystemctl restart docker
