k8s之harbor私有镜像仓库部署

　　一、安装docker-compose
　　下载地址：https://github.com/docker/compose/releases
　　文件下载下来是个二进制文件，加x权限放到/usr/bin目录下 [root@node4 harbor]# ls docker-compose-Linux-x86_64  harbor  harbor-offline-installer-v2.3.1.tgz [root@node4 harbor]# cp docker-compose-Linux-x86_64 /usr/bin/docker-compose [root@node4 harbor]# chmod +x /usr/bin/docker-compose二、安装harbor
　　下载地址：https://github.com/goharbor/harbor/releases
　　解压安装包，修改harbor.yml.tmpl文件并重命名成harbor.yml，这是harbor的配置文件，执行安装之前要改好，我这里只改了主机名和禁用了https [root@node4 harbor]# ls common     docker-compose.yml    harbor.yml           install.sh  prepare common.sh  harbor.v2.3.1.tar.gz  harbor.yml.tmpl.bak  LICENSE  [root@node4 harbor]# cat harbor.yml |grep hostname # The IP address or hostname to access admin UI and registry service. hostname: node4
　　在执行./install安装之前，确保docker处于运行状态。install完成后，默认使用80端口即访问。
　　三、harbor启动与停止
　　启动 ，启动时要进入harbor的安装目录 docker-compose up -d
　　停止 docker-compose stop四、docker登录harbor
　　http方式，需要修改/etc/dcoker/daemon.json {   ＂insecure-registries＂: [＂node4＂] }
　　登录 [root@node4 ~]# docker login  192.168.21.34 Authenticating with existing credentials... Stored credentials invalid or expired Username (admin):  Password:  WARNING! Your password will be stored unencrypted in /root/.docker/config.json. Configure a credential helper to remove this warning. See https://docs.docker.com/engine/reference/commandline/login/#credentials-store  Login Succeeded五、上传镜像到仓库
　　先pull一个nginx:1.15到本地，打tag，上传 [root@node4 ~]# docker pull nginx:1.15 1.15: Pulling from library/nginx 743f2d6c1f65: Pull complete  6bfc4ec4420a: Pull complete  688a776db95f: Pull complete  Digest: sha256:23b4dcdf0d34d4a129755fc6f52e1c6e23bb34ea011b315d87e193033bcd1b68 Status: Downloaded newer image for nginx:1.15 docker.io/library/nginx:1.15 [root@node4 ~]# docker tag nginx:1.15 192.168.21.34/release/nginx:v1.15 [root@node4 ~]# docker push 192.168.21.34/release/nginx:v1.15  The push refers to repository [192.168.21.34/release/nginx] 332fa54c5886: Pushed  6ba094226eea: Pushed  6270adb5794c: Pushed  v1.15: digest: sha256:e770165fef9e36b990882a4083d8ccf5e29e469a8609bb6b2e3b47d9510e2c8d size: 94 8
