Docker私有仓库Harbor部署与使用
一、harbor介绍
Harbor是一个用于存储和分发Docker镜像的企业级Registry服务器。
由下面几个组件组成:
- proxy:nginx前端代理,主要是分发前端页面ui访问和镜像上传和下载流量
- registry:镜像仓库,负责存储镜像文件
- 核心服务:提供web ui,数据库,token认证,webhook等功能
- 日志服务
- database:用来存储核心服务的一些数据
因为是vmware出品的,所以支持下面几种部署方式
- 在线安装
- 离线安装
- ova安装,这个直接在vcenter上导入就可以了
官方最小配置
- 2个cpu
- 4g内存
- 40g硬盘,因为是存储镜像的所以推荐硬盘大点
二、搭建过程
Install Docker CE
root@localhost:~# apt-get update root@localhost:~# apt-get install apt-transport-https ca-certificates software-properties-common curl root@localhost:~# curl -fsSL https://download.docker.com/linux/ubuntu/gpg |sudo apt-key add - root@localhost:~# apt-key fingerprint 0EBFCD88 root@localhost:~# add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" root@localhost:~# apt-get update root@localhost:~# apt-get install docker-ce
Install Docker-compose
root@localhost:~# curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose root@localhost:~# chmod +x /usr/local/bin/docker-compose #查看版本 root@localhost:~# docker --version Docker version 18.09.0, build 4d60db4 root@localhost:~# docker-compose --version docker-compose version 1.22.0, build f46880fe
Install harbor
root@localhost:~# wget https://storage.googleapis.com/harbor-releases/release-1.6.0/harbor-offline-installer-v1.6.0.tgz root@localhost:~# tar -zxvf harbor-offline-installer-v1.6.0.tgz #编辑配置文件 root@localhost:~# cd harbor/ root@localhost:~/harbor# vim harbor.cfg hostname = 114.112.34.27 project_creation_restriction = adminonly #Python环境 root@localhost:~/harbor# apt-get install python root@localhost:~/harbor# export LC_ALL=C root@localhost:~/harbor# ln -s /usr/bin/python3 /usr/bin/python #安装服务 root@localhost:~/harbor# ./install.sh
看到以下内容,说明安装成功:

配置HTTPS
##如果不做HTTPS,只需将hostname设置为IP,protocol改为HTTP即可,也不必生成CA root@localhost:~/harbor# vi harbor.cfg
#创建目录 root@localhost:~/harbor# mkdir -p /data/cert/ #生成ca证书和签名 root@localhost:~/harbor# openssl genrsa -out /data/cert/ca.key 2048 root@localhost:~/harbor# openssl req -x509 -new -nodes -key /data/cert/ca.key -subj "/CN=test.harbor.com" -days 5000 -out /data/cert/ca.crt #启动服务 root@localhost:~/harbor# ./prepare root@localhost:~/harbor# docker-compose down root@localhost:~/harbor# docker-compose up -d
测试
修改本地host,添加一行内容 114.112.34.27 test.harbor.com 在浏览器中访问 http://test.harbor.com/ 默认用户名/密码:admin/Harbor12345
登录成功后会看到如下页面:
添加项目:
进入此项目,可以看到推送镜像的命令:
删除项目:
确认项目不再使用时,选中项目,点击删除
点击删除:
在服务器进行测试
修改本地Docker默认仓库,指向Harbor
root@localhost:/data/cert# cp ca.crt /usr/local/share/ca-certificates/ root@localhost:/data/cert# update-ca-certificates #修改docker配置文件,指向Harbor root@localhost:~/harbor# vi /etc/default/docker #添加一行内容 DOCKER_OPTS="--insecure-registry=test.harbor.com" #重启docker服务 root@localhost:~# service docker restart
将本地Ubuntu镜像上传至Harbor
#将本地镜像打一个tag root@localhost:~# docker tag ubuntu:16.04 test.harbor.com/paas/ubuntu:v1.0 #推送到Harbor上 root@localhost:~/harbor# docker push test.harbor.com/paas/ubuntu:v1.0
下载Harbor镜像至本地
root@localhost:~/harbor# docker pull test.harbor.com/paas/ubuntu:v1.0 v1.0: Pulling from paas/ubuntu Digest: sha256:078d30763ae6697b7d55e49f4cb9e61407abd2137cafb5625f131aa47c1a47af Status: Downloaded newer image for test.harbor.com/paas/ubuntu:v1.0
