Harbor镜像仓库的安装与使用
简介：Harbor是一个用于存储和分发Docker镜像的企业级Registry服务器，除了Harbor这个私有镜像仓库外，还有Docker官方提供的Registry。相对Registry，Harbor具有很多优势,本文主要介绍Harbor镜像仓库的安装与使用，以及使用Docker从Harbor中上传与下载镜像
Harbor安装步骤
安装Docker-compose
官网下载地址——慢：
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
国内镜像加速下载地址——快：
sudo curl -L "https://get.daocloud.io/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
赋予执行权限：
sudo chmod +x /usr/local/bin/docker-compose
使用命令 docker-compose -v 查看 compose 版本：出现版本号说明安装成功
下载Harbor
harbor安装可以使用在线安装或者离线安装。在线安装需要联网所以体积非常小，离线安装的包比较大。在这里，由于github网站不通，我选择离线安装的方式
手动下载地址 https://github.com/goharbor/harbor/releases
# 将下载好的压缩包传到linux服务器
[root@iZwz9eq1jai7e87n6vw5liZ harbor]# ls
harbor-offline-installer-v1.5.0.tgz
[root@iZwz9eq1jai7e87n6vw5liZ harbor]# tar -zxf harbor-offline-installer-v1.5.0.tgz
[root@iZwz9eq1jai7e87n6vw5liZ harbor]# ls 解压之后的文件
harbor harbor-offline-installer-v1.5.0.tgz
修改harbor的配置文件
[root@iZwz9eq1jai7e87n6vw5liZ harbor]# vim harbor.cfg
hostname = 你主机IP #待会barbor启动成功后能访问的页面,默认80端口
执行 ./prepare
[root@iZwz9eq1jai7e87n6vw5liZ harbor]# ./prepare

[root@iZwz9eq1jai7e87n6vw5liZ harbor]# 启动成功，接着访问配置文件中配置的页面即可
Harbor的启动与停止
docker-compose up -d # 启动
docker-compose stop # 停止
docker-compose restart # 重新启动
harbor页面访问，使用默认的账户和密码 admin Harbor12345
在Harbor创建用户和项目
1）创建项目
Harbor的项目分为公开和私有的：
公开项目：所有用户都快要访问，通常存放公共的镜像，默认有一个library公开项目
私有项目：只有授权用户才可以访问，通换成那个存放项目本身的镜像
然后可以创建用户，并分配项目权限,之后上传镜像可以登录创建的用户
把本地镜像上传到Harbor
把本地jar包上传到linux服务器
[root@iZwz9eq1jai7e87n6vw5liZ makeImages]# ls

访问eureka地址
http://39.108.6.54:7001/
自测没问题，接下来就该测试上传这个镜像了！
把镜像上传到私有仓库Harbor
1、先给镜像打上标签
# test_micro_serve 为Harbor创建的仓库名字eureka:v1为给这个镜像取的名字
# eureka:v1为给这个镜像取的名字
[root@iZwz9eq1jai7e87n6vw5liZ makeImages]# docker tag eureka:v1 39.108.6.54/test_micro_serve/eureka:v1
[root@iZwz9eq1jai7e87n6vw5liZ makeImages]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
39.108.6.54/test_micro_serve/eureka v1 e38cc76e668f 11 minutes ago 145MB
eureka v1 e38cc76e668f 11 minutes ago 145MB
2、推送镜像
[root@iZwz9eq1jai7e87n6vw5liZ makeImages]# docker push 39.108.6.54/test_micro_serve/eureka:v1
报错： Get https://39.108.6.54/v2/: dial tcp 39.108.6.54:443: connect: connection refused
3、将Harbor仓库地址添加为Docker信任列表
# 编辑 /etc/docker 下的daemon.json文件
{
"registry-mirrors": ["https://ggb52j62.mirror.aliyuncs.com"],
"insecure-registries":["39.108.6.54"] # 将Harbor仓库的地址添加为Dokcer的信任列表
}
# 然后重启Docker
systemctl restart docker
4、再次执行推送命令,提示权限不足
[root@iZwz9eq1jai7e87n6vw5liZ harbor]# docker push 39.108.6.54/test_micro_serve/eureka:v1
The push refers to repository [39.108.6.54/test_micro_serve/eureka]

ceaf9e1ebef5: Preparing
9b9b7f3d56a0: Preparing
f1b5933fe4b5: Preparing
denied: requested access to the resource is denied # 提示权限不足，这是因为我们还没有登入Harbor的私有仓库，Docker并不知道要把这个镜像提交到哪里
5、登入Harborm，然后提交推送
[root@iZwz9eq1jai7e87n6vw5liZ harbor]# docker login -u pihao -p ****** 39.108.6.54
