容器技术之Docker私有镜像仓库harbor
docker-distribution搭建的仓库非常简陋，它甚至连一个用户认证都没有，更别提多用户；今天我们来介绍另外一款docker仓库工具harbor；harbor这款工具相对docker-distribution来讲功能上丰富了许多；它支持多租户，可扩展的API和web ui ，支持跨多个harbor实例的镜像复制，支持身份集成和基于角色的访问控制等等特征； 前文我们聊到了docker的私有镜像仓库docker-distribution的搭建和简单的使用，回顾请参考https://www.cnblogs.com/qiuhom-1874/p/13058338.html；从前文的搭建和使用过程来看，docker-distribution搭建的仓库非常简陋，它甚至连一个用户认证都没有，更别提多用户；今天我们来介绍另外一款docker仓库工具harbor；harbor这款工具相对docker-distribution来讲功能上丰富了许多；它支持多租户，可扩展的API和web ui ，支持跨多个harbor实例的镜像复制，支持身份集成和基于角色的访问控制等等特征；接下来我们来安装看看harbor吧；
首先我们要去官网下载安装器，目前最新版本是2.0；下载地址https://github.com/goharbor/harbor/releases/tag/v2.0.0；harbor的安装器有在线和离线两个版本，在线包通常较小，适用于网络环境较好地环境中使用，离线包是所有的安装文件和脚本等等打包在一起的；
1、上传已经下载好的安装器到服务器
2、解压安装器，并进入到解压后的目录中
[root@docker_node01 ~]# tar xf harbor-offline-installer-v2.0.0.tgz -C /usr/local/[root@docker_node01 ~]# ls /usr/local/bin etc games harbor include lib lib64 libexec sbin share src[root@docker_node01 ~]# cd /usr/local/harbor/[root@docker_node01 harbor]# lscommon.sh harbor.v2.0.0.tar.gz harbor.yml.tmpl install.sh LICENSE prepare[root@docker_node01 harbor]#
3、编辑harbor.yml.tmpl文件，更改必要的配置
提示：以上我只修改了hostname的值，后面的我都是用默认值；有关这个配置文件的说明，可参考官方文档说明去配置；这里需要注意一点使用https需要自己手动的去申请证书，没有证书文件harbor是不能够正常安装的；
4、把harbor.yml.tmpl重命名为harbor.yml
[root@docker_node01 harbor]# lscommon.sh harbor.v2.0.0.tar.gz harbor.yml.tmpl install.sh LICENSE prepare[root@docker_node01 harbor]# mv harbor.yml.tmpl harbor.yml[root@docker_node01 harbor]#
5、运行install.sh
提示：如果运行install.sh脚本出现以上错误，我们需要先安装好docker-compose;
6、安装docker-compose
[root@docker_node01 harbor]# yum install docker-compose -yLoaded plugins: fastestmirrorbase | 3.6 kB 00:00:00 docker-ce-stable | 3.5 kB 00:00:00 epel | 4.7 kB 00:00:00 extras | 2.9 kB 00:00:00 updates | 2.9 kB 00:00:00 (1/3): updates/7/x86_64/primary_db | 2.1 MB 00:00:00 (2/3): epel/x86_64/updateinfo | 1.0 MB 00:00:01 (3/3): epel/x86_64/primary_db | 6.8 MB 00:00:03 Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirror.bit.edu.cnResolving Dependencies--> Running transaction check---> Package docker-compose.noarch 0:1.18.0-4.el7 will be installed--> Processing Dependency: python36-cached_property >= 1.2.0 for package: docker-compose-1.18.0-4.el7.noarch--> Processing Dependency: python36-docker >= 2.6.1 for package: docker-compose-1.18.0-4.el7.noarch……省略部分内容Installed: docker-compose.noarch 0:1.18.0-4.el7 Dependency Installed: python36-PyYAML.x86_64 0:3.13-1.el7 python36-cached_property.noarch 0:1.5.1-2.el7 python36-chardet.noarch 0:3.0.4-1.el7 python36-docker.noarch 0:2.6.1-3.el7 python36-docker-pycreds.noarch 0:0.2.1-2.el7 python36-dockerpty.noarch 0:0.4.1-18.el7 python36-docopt.noarch 0:0.6.2-8.el7 python36-idna.noarch 0:2.7-2.el7 python36-jsonschema.noarch 0:2.5.1-4.el7 python36-pysocks.noarch 0:1.6.8-7.el7 python36-requests.noarch 0:2.14.2-2.el7 python36-six.noarch 0:1.14.0-2.el7 python36-texttable.noarch 0:1.6.2-1.el7 python36-urllib3.noarch 0:1.25.6-1.el7 python36-websocket-client.noarch 0:0.47.0-2.el7 Complete![root@docker_node01 harbor]#
提示：docker-compose是docker容器的单机编排工具；
7、再运行install.sh脚本

提示：从上面的信息可以看到harbor导入了很多镜像，然后基于各个镜像间的关系提供配置文件，然后按照一定的依赖关系顺序启动为容器；我们用docker images 可以来看看它导入了那些镜像

提示：可以看到本地仓库中多了很多镜像，同时也启动了很多容器；其中名为nginx的容器把80端口暴露到数组机上了；到此harbor就安装好了；接下来我们访问宿主机的80端口看看是否能够访问到harbor
提示：以上就是harbor的web 页面，默认用户名是admin密码是Harbor12345
登录harbor web页面
提示：我们就可以基于这个web页面来做管理了；接下来我们先创建一个用户和项目，然后在通过docker push上传镜像到harbor上
创建用户
提示：填写好以上信息，点击确定用户就创建好了；
创建项目
提示：如果创建的项目是私有的，把访问级别后面的公开对勾取消即可
从别的docker主机上上传镜像到harbor
提示：使用非https的仓库必须要在daemon.json文件中配置insecure-registries来声明不安全的镜像仓库地址；
提示：这里提示我们未授权；接下来我们去web管理页面授权qiuhom是test项目的成员；
提示：现在我们把qiuhom这个用户设置为test这个项目的管理员，现在我们在以qiuhom的身份推镜像到test项目中，看看是否能够成功把进行推送到harbor上？

提示：这次推送镜像没有报错，我们去web页面中看看镜像是否推送到test项目中去了？
验证：在harborweb界面看看是否有我们推上去的镜像？
用其他docker主机下载harbor上的镜像
提示：可以看到现在我们搭建的harbor是可以正常下载和上传镜像的；管理镜像我们可以通过web页面管理即可，我这里就不去演示了；接下来我们再来说说在命令行用docker-compose启动harbor和停止harbor吧
停止harbor
提示：用docker-compose停止harbor需要先进入到harbor目录下，然后执行docker-compose stop 这条命令会去寻找docker-compose.yml文件，根据文件中定义的服务来停止容器；这个有点类似docker build命令，找Dockerfile文件，而docker-compose 是找docker-compose.yml；这里还需要注意一点的是这个文件名必须是docker-compose.yml；
启动harbor
提示：启动huabor同停止harbor一样都必须在docker-compose.yml文件所在目录下执行docker-compose start 或docker-compose up -d ；
