Harbor镜像仓库部署

一、简介

Harbor是VMware中国研发团队开发并开源企业级Registry，对中文支持很友好。
Harbor是一个用于存储和分发Docker镜像的企业级Registry服务器。
Harbor具有如下特点:
1.基于角色的访问控制 - 用户与Docker镜像仓库通过“项目”进行组织管理，一个用户可以对多个镜像仓库在同一命名空间（project）里有不同的权限。

2.镜像复制 - 镜像可以在多个Registry实例中复制（同步）。尤其适合于负载均衡，高可用，混合云和多云的场景。
3.图形化用户界面 - 用户可以通过浏览器来浏览，检索当前Docker镜像仓库，管理项目和命名空间。
4.AD/LDAP 支持 - Harbor可以集成企业内部已有的AD/LDAP，用于鉴权认证管理。
5.审计管理 - 所有针对镜像仓库的操作都可以被记录追溯，用于审计管理。
6.国际化 - 已拥有英文、中文、德文、日文和俄文的本地化版本。更多的语言将会添加进来。
7.RESTful API - RESTful API 提供给管理员对于Harbor更多的操控, 使得与其它管理软件集成变得更容易。
8.部署简单 - 提供在线和离线两种安装工具， 也可以安装到vSphere平台(OVA方式)虚拟设备。

二、Harbor 获取地址

三、Harbor 安装前准备
1.安装 docker

# yum install -y yum-utils device-mapper-persistent-data lvm2
# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo # yum -y install docker-ce
# docker --version
Docker version 17.06.2-ce, build cec0b72
# systemctl start docker
# systemctl status docker
# systemctl enable docker

2.安装 docker-compose

# yum -y install python-pip
# pip install --upgrade pip
# pip -V
pip 9.0.1 from /usr/lib/python2.7/site-packages (python 2.7)
# pip install docker-compose
# docker-compose version

OpenSSL version: OpenSSL 1.0.1e-fips 11 Feb 2013

四、安装 Habor
1.解压并载入镜像(注:制作本文档时harbor版本已更新至1.2.2，请自行下载)

# tar -zxvf harbor-offline-installer-v1.2.0.tgz
# cd harbor
# docker load -i harbor.v1.2.0.tar.gz
# docker images

2.配置 harbor

# sed -i "s/reg.mydomain.com/192.168.100.100/g" harbor.cfg
# sed -i "s/sample_admin/admin/g" harbor.cfg     ##该命令纯属为了好看，并没有使用相关配置
# grep ^[a-z] harbor.cfg                       ###能看则看
### 指定 harbor 的主机名,可以是IP地址，也可以是域名(不能注释再指定)
hostname = 192.168.100.100
### 指定用户访问使用的协议，默认http
ui_url_protocol = http
### 指定 mysql 数据库管理员密码
db_password = root123
### 作业服务中的最大复制worker数(缺省值为3)
max_job_workers = 3
### 是否允许创建用于生成/验证注册表令牌的私钥和根证书(默认为on)
customize_crt = on
### 设置证书文件路径
ssl_cert = /data/cert/server.crt
ssl_cert_key = /data/cert/server.key
secretkey_path = /data
admiral_url = NA
clair_db_password = password
### 邮件相关信息配置
email_identity =
### 配置邮件服务器地址
email_server = smtp.mydomain.com
### 配置邮件服务器端口
email_server_port = 25
### 配置用户
email_username = admin@mydomain.com
### 配置密码
email_password = abc
### 配置发件人地址
email_from = admin <admin@mydomain.com>
### 配置是否进行ssl加密
email_ssl = false
### 指定 harbor 管理员密码
harbor_admin_password = Harbor12345
### 使用的认证类型。默认为db_auth，即凭据存储在MySQL数据库中(Harbor还 支持本地及LDAP认证方式)
auth_mode = db_auth
### LDAP端点URL，仅当auth_mode设置为ldap_auth时使用
ldap_url = ldaps://ldap.mydomain.com
### 查找用户的基本DN，仅当auth_mode设置为ldap_auth时使用
ldap_basedn = ou=people,dc=mydomain,dc=com
### 用于在LDAP搜索期间匹配用户的属性
ldap_uid = uid
### 用于搜索用户的范围
ldap_scope = 3
## 设置LDAP超时时间
ldap_timeout = 5
### 是否允许开放注册(默认允许)
self_registration = on
### 令牌服务创建的令牌的过期时间(以分钟为单位，默认30分钟)
token_expiration = 30
### 用户创建项目的权限，默认是everyone（所有人），也可以设置为adminonly（只有管理员才能创建）
project_creation_restriction = everyone
### 确定当 Harbor 与远程注册表实例通信时是否验证SSL / TLS证书
verify_remote_cert = on

注:harbor 的主机名 hostname 不能注释再指定，必须删除默认设置再指定主机名，不然会产生错误。

4.查看容器状况

# 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

registry             /entrypoint.sh serve /etc/ ...   Up      5000/tcp

Harbor共由七个容器组成:

a.harbor-adminserver:harbor系统管理服务
b.harbor-db: 由官方mysql镜像构成的数据库容器
c.harbor-jobservice:harbor的任务管理服务
d.harbor-log:harbor的日志收集、管理服务
e.harbor-ui:harbor的web页面服务
f.nginx:负责流量转发和安全验证
g.registry:官方的Docker registry，负责保存镜像

5.应用 harbor

浏览器输入 http://harborip 登陆 harbor 镜像仓库页面(帐号admin，密码为harbor.cfg默认密码Harbor12345)



进入harbor后界面如下




新建项目(注:默认项目是私有的，公开请打勾)




新建完成之后就可以上传镜像到 harbor 镜像仓库了。

a.更改 docker 配置

# grep "ExecStart" /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd --insecure-registry=192.168.100.100
# systemctl daemon-reload
# systemctl restart docker

注:docker默认使用https传输镜像，这里使用的是http，所以需要指定，无论上传还是下载都需要指定

b.登陆 harbor(注:第一种方便，第二种安全，实际中请使用第二种)

# docker login -u admin -p Harbor12345 192.168.100.100
Login Succeeded

# docker login 192.168.100.100
Username: admin
Password:
Login Succeeded

c.给镜像打 tag 并上传至 harbor

# docker tag 99e59f495ffa 192.168.100.100/k8s/pause-amd64:3.0
# docker push 192.168.100.100/k8s/pause-amd64:3.0
The push refers to a repository [192.168.100.100/k8s/pause-amd64]
5f70bf18a086: Pushed
41ff149e94f2: Pushed
3.0: digest: sha256:f04288efc7e65a84be74d4fc63e235ac3c6c603cf832e442e0bd3f240b10a91b size: 939

d.查看上传情况





e.下载镜像(pull命令如下图)
