鏡像倉庫Harbor私服高可用策略分析及部署

```# 一．分析指定Harbor高可用策略

主流的策略有那麼幾種:
1.harbor做雙主複製
2.harbor集羣掛載分佈式cephfs存儲
3.在k8s集羣上部署harbor

第二種和第三種都是多個節點，然後掛載的分佈式存儲，然後爲了保證數據的統一性使用單獨的mysql數據庫，這樣以來存在mysql數據和鏡像倉庫數據單點存放，故障恢復難度大，安裝操作複雜的問題

雙主複製不存在這些問題，數據多點存放，而且擴容更改高可用模式操作簡單，可以更換成主主從等模式。

二．安裝docker-compose

#cat -a /etc/sysctl.conf <<-EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
然後重新加載 sysctl.conf 即可

#sysctl -p

最好在ifcnf-eth0中配置dns參數，hosts千萬不要配置域名和ip。

安裝docker-compose
方法一
curl -L https://github.com/docker/compose/releases/download/1.18.0/docker-compose-`uname -s-uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
#查看版本
docker-compose version

方法二
CentOS:
yum install epel-release -y
yum install python-pip -y
Ubuntu:
apt-get install python-pip -y

pip --version
pip install --upgrade pip
pip install -U -i https://pypi.tuna.tsinghua.edu.cn/simple docker-compose
docker-compose version
這裏採用方法2

二．安裝Harbor

Harbor私有倉庫的安裝
2個節點安裝步驟一致
• 下載Harbor安裝文件
從 github harbor 官網 release 頁面下載指定版本的安裝包。
1、在線安裝包（不一定好使，自己找源）
$ wget https://github.com/vmware/harbor/releases/download/v1.1.2/harbor-online-installer-v1.1.2.tgz
$ tar xvf harbor-online-installer-v1.1.2.tgz
2、離線安裝包
$ wget https://github.com/vmware/harbor/releases/download/v1.1.2/harbor-offline-installer-v1.1.2.tgz
$ tar xvf harbor-offline-installer-v1.1.2.tgz

本次離線安裝。
推薦使用第二種，因爲第一種在線安裝可能由於官網源的網絡波動導致安裝失敗。
• 配置Harbor
解壓縮之後，目錄下回生成harbor.conf文件，該文件就是Harbor的配置文件。

啓動 Harbor
修改完配置文件後，在的當前目錄執行./install.sh，Harbor服務就會根據當期目錄下的docker-compose.yml開始下載依賴的鏡像，檢測並按照順序依次啓動各
./install.sh

四．配置https域名證書等

X509存在一些問題在對v3_ca

#vim /etc/pki/tls/openssl.cnf
[ v3_ca ]

subjectAltName = IP:192.168.0.64 #添加

因爲要配置https，需要生成自簽名的證書

#cd /data/harbor-data/cert
#openssl req -nodes -subj "/C=CN/ST=BeiJing/L=ChaoYao/CN=basic-repository.xxxx.com" -newkey rsa:2048 -keyout basic-repository.key -out basic-repository.csr

#openssl x509 -req -days 3650 -in basic-repository.csr -signkey basic-repository.key -out basic-repository.crt

#openssl x509 -req -in basic-repository.csr -CA basic-repository.crt -CAkey basic-repository.key -CAcreateserial -out basic-repository.crt -days 10000

如下目錄是nginx容器的cert目錄：（不一定會自己生成）
#mkdir /data/harbor_install/harbor/common/config/nginx/cert/

#ls /etc/docker/certs.d/
basic-registry.xxxx.com basic-repository.xxxx.com redhat.com redhat.io registry.access.redhat.com registry.xxxx.com repository.xxxx.com
#scp –a basic-repository.crt docker-IP:/etc/docker/cert.d/ basic-repository.xxxx.com

在傳完證書的docker服務器上執行：
#mkdir –pv /etc/docker/cert.d/basic-repository.xxxx.com
#service docker restart

#docker login -u admin -p Harbor123456 repository.xxxx.com
1、停止Harbor
#docker-compose down -v
Stopping nginx ... done
Stopping harbor-jobservice ... done
......
Removing harbor-log ... done
Removing network harbor_harbor

#docker-compose stop

2、啓動Harbor
#docker-compose up -d
Creating network "harbor_harbor" with the default driver
Creating harbor-log ...
......
Creating nginx
Creating harbor-jobservice ... done

#docker-compose start

#docker-compose up –d

3.當需要修改配置文件刷新配置時需要執行： #./prepare

Test：
#docker login -u admin -p Harbor repository.xxxx.com
#ls /etc/docker/certs.d/
#docker pull basic-registry.xxxx.com/xxxx/dubbo:latest
#docker images
#docker tag basic-registry.xxxx.com/xxxx/dubbo:latest repository.xxxx.com/basic/dubbo:latest
#docker push repository.xxxx.com/basic/dubbo:latest
