docker之企业级镜像仓库Harbor
Harbor概述
Habor是由VMWare公司开源的容器镜像仓库。事实上，Habor是在Docker Registry上进行了相应的
企业级扩展，从而获得了更加广泛的应用，这些新的企业级特性包括：管理用户界面，基于角色的访
问控制 ，AD/LDAP集成以及审计日志等，足以满足基本企业需求。

Harbor部署
Harbor安装有3种方式：
• 在线安装：从Docker Hub下载Harbor相关镜像，因此安装软件包非常小
• 离线安装：安装包包含部署的相关镜像，因此安装包比较大
• OVA安装程序：当用户具有vCenter环境时，使用此安装程序，在部署OVA后启动Harbor
Harbor部署
包路径： 链接：https://pan.baidu.com/s/1QhCjEAoEepqELhm9IvMOTA
有了harbor就不需要连外网下载镜像了。harbor一般部署在宿主机上。
我们将harbor的包上传到主机上，解压，配置。需要修改一下访问地址，我们这里配置成本机ip，修改一下密码，默认登录密码Harbor12345 。
[root@mcwk8s01 ~]# ls
anaconda-ks.cfg harbor-offline-installer-v1.6.1.tgz keepalived.conf nginx.sh
[root@mcwk8s01 ~]# tar xf harbor-offline-installer-v1.6.1.tgz
[root@mcwk8s01 ~]# ls
anaconda-ks.cfg harbor harbor-offline-installer-v1.6.1.tgz keepalived.conf nginx.sh
[root@mcwk8s01 ~]# cd harbor/
[root@mcwk8s01 harbor]# ls
common docker-compose.chartmuseum.yml docker-compose.clair.yml docker-compose.notary.yml docker-compose.yml ha harbor.cfg harbor.v1.6.1.tar.gz install.sh LICENSE NOTICE open_source_license prepare
[root@mcwk8s01 harbor]# vim harbor.cfg
[root@mcwk8s01 harbor]# egrep "10.0.0.31|Harbor12345" harbor.cfg
hostname = 10.0.0.31
harbor_admin_password = Harbor12345
[root@mcwk8s01 harbor]#
如果需要使用https那修改下配置：ui_url_protocol = http
它是使用docker compose来编排部署的。所以我们可以去去下载一个。安装方式如下链接参考
因为harbor自己要起nginx，会占用80服务，我们主机1上有nginx。那么我们换到主机5上面去把=吧

如下，进入了登录页面了
默认用户 admin
默认用户密码 Harbor12345
登录之后默认有个仓库，是个公共的仓库，我们可以往里面上传镜像。我们主要用的项目和用户。

推送镜像的参考命令
这个配置的地址有问题，我们之前在31上配置的。传到35上了，但是没有修改配置，配置那么多。我们重新部署一下吧

重新部署之后就对了。我是将harbor目录删除了，重新上传的，但是刚刚创建的成员machangwei还在的，看来数据库或者是存储的数据是在别处，没有受到影响吗。
推送镜像到harbor
推送总结
1、配置http镜像仓库可信任
# vi /etc/docker/daemon.json
{"insecure-registries":["reg.ctnrs.com"]}
# systemctl restart docker
2、打标签
# docker tag centos:6 reg.ctnrs.com/library/centos:6
3、上传
# docker push reg.ctnrs.com/library/centos:6
4、下载
# docker pull reg.ctnrs.com/library/centos:6
推送案例
如推荐的推送案例，我们需要打上标签，标签地址是我们的项目访问地址，然后push这个有仓库地址标签的镜像
打个标签

点击进入，看到推送的信息
我们再把nginx推送上去，把tomcat再推送第二个版本上去。需要注意的是，我们推送前一定要打上我们自己仓库的地址的镜像标签，推送这个有标签的镜像，别直接推送未打标签的，省的推送到别人的仓库了。

我们再看下，这个仓库中的tomcat有两个版本了
仓库中有两个镜像
我们想要下载指定镜像指定版本的话可以在这里看下载地址，复制命令
比如上面我们复制的是 docker pull 10.0.0.35/library/tomcat:v1
我们在另一台主机，主机6上下载一下。我们下载的主机，由于harbor是http方式的，我们也需要添加配置，让harbor主机是受信任的
[root@mcwk8s06 ~]# docker pull 10.0.0.35/library/tomcat:v1
