docker-registry registry用于保存docker镜像,包括镜像的层次结构和元数据; 用户可以自建registry,也可使用官方的Docker Hub; 分类: sponsor registry :第三方的registry,供客户和docker社区使用; mirror registry:第三方的registry,只让客户使用; vendor registry:由发布docker镜像的供应商提供的registry; private registry:通过设有防火墙和额外的安全层的私有实体提供的registry; 安装: # wget http://mirrors.aliyun.com/repo/Centos-7.repo # wget http://mirrors.163.com/.help/CentOS7-Base-163.repo # yum info docker-registry # yum install docker-registry rpm -ql docker-distribution-2.6.2-2.git48294d9.el7.x86_64 /etc/docker-distribution/registry/config.yml #配置文件 /usr/bin/registry /usr/lib/systemd/system/docker-distribution.service #启动服务 /usr/share/doc/docker-distribution-2.6.2 /usr/share/doc/docker-distribution-2.6.2/AUTHORS /usr/share/doc/docker-distribution-2.6.2/CONTRIBUTING.md /usr/share/doc/docker-distribution-2.6.2/LICENSE /usr/share/doc/docker-distribution-2.6.2/MAINTAINERS /usr/share/doc/docker-distribution-2.6.2/README.md /var/lib/registry #镜像存放路径 # cat /etc/docker-distribution/registry/config.yml version: 0.1 log: fields: service: registry storage: cache: layerinfo: inmemory filesystem: rootdirectory: /var/lib/registry http: addr: :5000 # :5000表示监听本机的5000端口 docker-registry启动: # systemctl start docker-distribution.service # ss -tnl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 5 192.168.122.1:53 *:* LISTEN 0 128 *:22 *:* LISTEN 0 128 127.0.0.1:631 *:* LISTEN 0 128 :::5000 :::* LISTEN 0 128 :::6443 :::* LISTEN 0 128 :::2379 :::* LISTEN 0 128 :::10251 :::* LISTEN 0 128 :::10252 :::* LISTEN 0 128 :::8080 :::* LISTEN 0 128 :::80 :::* 将镜像推送到docker-registry: 在client端: # docker tag docker.io/nginx centos7.cluster.com:5000/nginx:v1.0 # docker push centos7.cluster.com:5000/nginx:v1.0 注:这样推送会报错,Get https://centos7.cluster.com:5000/v1/_ping: ,客户端使用的https协议,而docker-registry使用http 解决方法: # vi /etc/docker/daemon.json { "registry-mirrors": ["https://registry.docker-cn.com"], "insecure-registries": ["centos7.cluster.com:5000"] } 重启docker服务,重新推送镜像。 在docker-registry服务器上查看推送上来的镜像: # ls -l /var/lib/registry
