大家好，又见面了，我是你们的朋友全栈君。
一、Harbor介绍
Docker容器应用的开发和运行离不开可靠的镜像管理，虽然Docker官方也提供了公共的镜像仓库，但是从安全和效率等方面考虑，部署私有环境内的Registry也是非常必要的。Harbor是由VMware公司开源的企业级的Docker Registry管理项目，它包括权限管理(RBAC)、LDAP、日志审核、管理界面、自我注册、镜像复制和中文支持等功能
二、环境准备
Harbor的所有服务组件都是在Docker中部署的，所以官方安装使用Docker-compose快速部署，所以需要安装Docker、Docker-compose。由于Harbor是基于Docker Registry V2版本，所以就要求Docker版本不小于1.10.0，Docker-compose版本不小于1.6.0
1）、安装并启动Docker
安装所需的包。yum-utils提供了yum-config-manager 效用，并device-mapper-persistent-data和lvm2由需要 devicemapper存储驱动程序
[root@localhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
设置稳定存储库
[root@localhost ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
安装Docker CE
[root@localhost ~]# yum install -y docker-ce docker-ce-cli containerd.io
2）、安装Docker-compose
下载指定版本的docker-compose
[root@localhost ~]# curl -L https://github.com/docker/compose/releases/download/1.13.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
对二进制文件赋可执行权限
[root@localhost ~]# chmod +x /usr/local/bin/docker-compose
测试下docker-compose是否安装成功
[root@localhost ~]# docker-compose --version
docker-compose version 1.13.0, build 1719ceb
三、Harbor服务搭建及启动
1）、下载Harbor安装文件
从GitHub上https://github.com/goharbor/harbor/releases下载指定版本的安装包
[root@localhost ~]# mkdir -p /harbor
[root@localhost ~]# cd /harbor/
[root@localhost harbor]# yum -y install wget
[root@localhost harbor]# wget https://github.com/vmware/harbor/releases/download/v1.1.2/harbor-online-installer-v1.1.2.tgz
[root@localhost harbor]# ls
harbor-online-installer-v1.1.2.tgz
[root@localhost harbor]# tar -zxf harbor-online-installer-v1.1.2.tgz
2）、配置Harbor
[root@localhost harbor]# ls
harbor harbor-online-installer-v1.1.2.tgz
[root@localhost harbor]# cd harbor
[root@localhost harbor]# ls
common docker-compose.notary.yml docker-compose.yml harbor_1_1_0_template harbor.cfg install.sh LICENSE NOTICE prepare upgrade
[root@localhost harbor]# vi harbor.cfg
配置文件harbor.cfg详解：
# hostname设置访问地址，可以使用ip、域名，不可以设置为127.0.0.1或localhost
hostname = 192.168.126.162
# 访问协议，默认是http，也可以设置https，如果设置https，则nginx ssl需要设置on
ui_url_protocol = http
# mysql数据库root用户默认密码root123，实际使用时修改下
db_password = 123456
max_job_workers = 3
customize_crt = on
ssl_cert = /data/cert/server.crt
ssl_cert_key = /data/cert/server.key
secretkey_path = /data
admiral_url = NA
# 邮件设置，发送重置密码邮件时使用
email_identity =
email_server = smtp.mydomain.com
email_server_port = 25
email_username = sample_admin@mydomain.com
email_password = abc
email_from = admin <sample_admin@mydomain.com>
email_ssl = false
# 启动Harbor后，管理员UI登录的密码，默认是Harbor12345
harbor_admin_password = 123456
# 认证方式，这里支持多种认证方式，如LADP、本次存储、数据库认证。默认是db_auth，mysql数据库认证
auth_mode = db_auth
# LDAP认证时配置项
ldap_url = ldaps://ldap.mydomain.com
#ldap_searchdn = uid=searchuser,ou=people,dc=mydomain,dc=com
#ldap_search_pwd = password
ldap_basedn = ou=people,dc=mydomain,dc=com
#ldap_filter = (objectClass=person)
ldap_uid = uid
ldap_scope = 3
ldap_timeout = 5
# 是否开启自注册
self_registration = on
# token有效时间，默认30分钟
token_expiration = 30
# 用户创建项目权限控制，默认是everyone（所有人），也可以设置为adminonly（只能管理员）
project_creation_restriction = everyone
verify_remote_cert = on
3）、启动Harbor
修改完配置文件后，在的当前目录执行./install.sh，Harbor服务就会根据当期目录下的docker-compose.yml开始下载依赖的镜像，检测并按照顺序依次启动各个服务
[root@localhost harbor]# ./install.sh
Harbor依赖的镜像及启动服务如下：
[root@localhost harbor]# docker-compose ps
Name Command State Ports
------------------------------------------------------------------------------------------------------------------------------
harbor-adminserver /harbor/harbor_adminserver Up
harbor-db docker-entrypoint.sh mysqld Up 3306/tcp
harbor-jobservice /harbor/harbor_jobservice Up
harbor-log /bin/sh -c crond && rm -f ... Up 127.0.0.1:1514->514/tcp
harbor-ui /harbor/harbor_ui Up
nginx nginx -g daemon off; Up 0.0.0.0:443->443/tcp, 0.0.0.0:4443->4443/tcp, 0.0.0.0:80->80/tcp
registry /entrypoint.sh serve /etc/ ... Up 5000/tcp
启动完成后，访问刚设置的hostname即可，默认是80端口，如果端口占用，可以去修改docker-compose.yml文件中，对应服务的端口映射
四、Harbor仓库使用
1）、登录Web Harbor
使用admin用户登录，密码为harbor.cfg配置的密码
2）、上传镜像到Harbor仓库
我们新建一个名称为harbor的项目，设置不公开。当项目设为公开后，任何人都有此项目下镜像的读权限。命令行用户不需要docker login就可以拉取此项目下的镜像。
新建项目后，使用admin用户提交本地nginx镜像到Harbor仓库
1）admin登录
使用docker login出现如下问题：
[root@localhost ~]# docker login 192.168.126.162
Username: admin
Password:
Error response from daemon: Get https://192.168.126.162/v2/: read tcp 192.168.126.162:49654->192.168.126.162:443: read: connection reset by
peer
解决方法：
查找docker.service所在的位置
[root@localhost ~]# find / -name docker.service -type f
/usr/lib/systemd/system/docker.service
修改配置文件，ExecStart之后添加–insecure-registry=http://192.168.126.162
重启Docker服务
再次进行登录
[root@localhost ~]# docker login 192.168.126.162
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
2）给镜像打tag
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
vmware/harbor-jobservice v1.1.2 4ef0a7a33734 24 months ago 163MB

vmware/harbor-log v1.1.2 9c46a7b5e517 2 years ago 192MB
3）push到仓库
[root@localhost ~]# docker push 192.168.126.162/harbor/nginx:latest
The push refers to repository [192.168.126.162/harbor/nginx]
3569f62067e2: Pushed
3f117c44afbb: Pushed
c4a8b7411af4: Pushed

上传成功后，登录Web Harbor，选择项目harbor，就可以查看刚刚上传的nginx镜像了
3）、创建用户并分配权限
点击系统管理下的用户管理，点击创建用户，输入相关信息
将刚刚创建的用户添加到harbor项目成员中，点击项目，选择harbor项目，点击成员，点击添加成员，添加姓名选择角色
使用新建的用户将刚刚上传的nginx镜像拉取下来
先将刚刚nginx镜像删除
[root@localhost ~]# docker images

退出admin帐号，使用刚刚创建的用户登录
[root@localhost ~]# docker logout 192.168.126.162
