Harbor仓库搭建及简单使用

最近跟甲方合作一个项目 要求docker部署,之前自己的镜像没有用自己的私有服务器,甲方用的是Harbor,之前自己也有接触过,这次正好学习记录下

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

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

1
[root@localhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2

设置稳定存储库

1
[root@localhost ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

安装Docker CE

1
[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

1
[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

1
[root@localhost ~]# chmod +x /usr/local/bin/docker-compose

测试下docker-compose是否安装成功

1
2
[root@localhost ~]# docker-compose --version
docker-compose version 1.13.0, build 1719ceb
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

[root@localhost harbor]# cd harbor
[root@localhost harbor]# ls

[root@localhost harbor]# vi harbor.cfg

# 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

1
[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

Harbor仓库使用

1)、登录Web Harbor
登录web
使用admin用户登录，密码为harbor.cfg配置的密码
登陆后
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。
创建项目
新建项目后，使用admin用户提交本地nginx镜像到Harbor仓库
3)、本地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

1
2
[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
