Harbor Docker 鏡像倉庫搭建

Harbor是一個用於存儲和分發Docker鏡像的企業級Registry服務器，經過添加一些企業必需的功能特性，例如安全、標識和管理等，擴展了開源Docker Distribution。

環境：Centos 7

1.Docker環境安裝 並啓動本地Docker環境

#列出版本信息
yum list docker-ce --showduplicates | sort -r

#安裝指定版本
yum install docker-ce-17.03.0.ce-1.el7.centos

#安裝
yum install -y docker

#啓動
systemctl start docker

#驗證環境就緒
docker run hello-world

yum remove docker docker-common docker-selinux

yum install https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch.rpm

2.安裝Docker-Compose

Docker-Compose下載地址：https://github.com/docker/compose/releases/

#進入指定目錄（自由指定）
cd /usr/server
#下載
curl -L https://github.com/docker/compose/releases/download/1.14.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
#可執行賦權
chmod +x /usr/local/bin/docker-compose
#查看版本驗證安裝
docker-compose --version

3.安裝Harbor

Harbor下載地址：https://github.com/vmware/harbor/releases

選擇須要的版本下載，這裏選擇1.1.2

#下載tar包
wget https://github.com/vmware/harbor/releases/download/v1.1.2/harbor-online-installer-v1.1.2.tgz
#解壓
tar zxf harbor-online-installer-v1.1.2.tgz
#解析後進入harbor目錄
cd harbor

修改harbor.cfg配置文件,完整配置文件見最後附錄

爲簡單起見我這裏只修改兩個位置

a.爲了讓外網能夠訪問到 修改hostname爲機器的公網IP

b.修改UI管理系統的管理員密碼 harbor_admin_password = admin123

保存修改後運行當前目錄下的安裝腳本install.sh

./install.sh

自動安裝腳本會下載幾個docker鏡像並啓動，

注意默認web服務nginx鏡像綁定80端口，nginx鏡像啓動失敗請先釋放80端口。

安裝完成後訪問IP或者綁定的域名就能夠訪問到Harbor的管理界面。以下：

4.Harbor的啓停

#啓動
docker-compose start

#中止
docker-compose stop

5.配置Docker

由於docker默認使用的是https鏈接，而harbor默認使用http鏈接，因此須要修改docker配置標誌insecure registry不安全倉庫的主機！
harbor也能夠設置爲https。

vim /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd --insecure-registry=94.191.16.123
#只加上--insecure-registry這個參數便可

#重啓docker：
systemctl daemon-reload
systemctl restart docker.service

 

6.進階配置

6.1 修改nginx鏡像的端口

nginx鏡像默認監聽80端口，爲安全因素或避免衝突能夠改成其餘端口，此處我改成8820端口

6.1.1 編輯Harbor目錄下的docker-compose.yml文件（完整文件見附錄二），找到nginx鏡像節點 修改以下：

proxy:
    image: nginx:1.11.5
    container_name: nginx
    restart: always
    volumes:
      - ./common/config/nginx:/etc/nginx
    ports:
      - 8820:80
      - 1143:443
    depends_on:
      - mysql
      - registry
      - ui
      - log

6.1.2 修改common/templates/registry/config.yml文件加入8820端口：

#vim common/templates/registry/config.yml

auth:
  token:
    issuer: registry-token-issuer
    realm: $ui_url:8820/service/token
    rootcertbundle: /etc/registry/root.crt
    service: token-service

6.1.3 中止harbor，從新啓動並生成配置文件：

docker-compose stop
./install.sh

6.1.4 修改docker啓動文件，設置信任的主機與端口（第五步配置docker中修改端口80爲8820）：

vim /usr/lib/systemd/system/docker.service  修改以下一行
ExecStart=/usr/bin/dockerd --insecure-registry=172.16.103.99:1180

6.1.5 從新啓動docker並驗證：

systemctl daemon-reload
systemctl restart docker.service

登陸驗證

docker login 94.191.16.123:8820
Username: admin
Password: 
Login Succeeded

 

遇到的問題：

1.安裝執行install.sh報錯 File "./prepare", line 60 os.makedirs(folder, mode=0600)

查緣由發如今執行python 腳本 prepare時報錯，prepare腳本基於python2.7 當前機器默認python環境被我改成python3.7 改回原版安裝便可

mv python python3.7.2.bak
mv python2.7.bak python
python --version

#Timeout (in seconds)  when connecting to an LDAP Server. The default value (and most reasonable) is 5 seconds.
ldap_timeout = 5

#Turn on or off the self-registration feature
self_registration = on

#The expiration time (in minute) of token created by token service, default is 30 minutes
token_expiration = 30

#The flag to control what users have permission to create projects
#The default value "everyone" allows everyone to creates a project. 
#Set to "adminonly" so that only admin user can create project.
project_creation_restriction = everyone

#Determine whether the job service should verify the ssl cert when it connects to a remote registry.
#Set this flag to off when the remote registry uses a self-signed or untrusted certificate.
verify_remote_cert = on
