高可用策略
主流的策略有那么几种:
1.harbor 做双主复制
2.harbor 集群挂载分布式 cephfs 存储
3. 在 k8s 集群上部署 harbor
- 1. 第二种和第三种都是多个节点,然后挂载的分布式存储,然后为了保证数据的统一性使用单独的 mysql 数据库,这样以来存在 mysql 数据和镜像仓库数据单点存放,故障恢复难度大,安装操作复杂的问题
- 2. 双主复制不存在这些问题,数据多点存放,而且扩容更改高可用模式操作简单,可以更换成主主从等模式。
二.安装 docker-compose
#cat -a /etc/sysctl.conf <<-EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
然后重新加载 sysctl.conf 即可
#sysctl -p
最好在 ifcnf-eth0 中配置 dns 参数,hosts 千万不要配置域名和 ip。
安装 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
# 通用命令
pip --version
pip install --upgrade pip
pip install -U -i https://pypi.tuna.tsinghua.edu.cn/simple docker-compose
docker-compose version
这里采用方法 2
二.安装 Harbor
Harbor 私有仓库的安装
2 个节点安装步骤一致
• 下载 Harbor 安装文件
从 github harbor 官网 release 页面下载指定版本的安装包。
1、在线安装包(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、离线安装包
$ 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
- 本次离线安装。
推荐使用第二种,因为第一种在线安装可能由于官网源的网络波动导致安装失败。
• 配置 Harbor
解压缩之后,目录下回生成 harbor.conf 文件,该文件就是 Harbor 的配置文件。

* 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
./install.sh
四.配置 https 域名证书等
X509 存在一些问题在对 v3_ca
#vim /etc/pki/tls/openssl.cnf
[v3_ca]
# Extensions for a typical CA
subjectAltName = IP:192.168.0.64 #添加
因为要配置 https,需要生成自签名的证书
#cd /data/harbor-data/cert
#openssl req -nodes -subj "/C=CN/ST=BeiJing/L=ChaoYao/CN=basic-repository.skong.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
* 如下目录是 nginx 容器的 cert 目录:(不一定会自己生成)
#mkdir /data/harbor_install/harbor/common/config/nginx/cert/
# ls /etc/docker/certs.d/
basic-registry.skong.com basic-repository.skong.com redhat.com redhat.io registry.access.redhat.com registry.skong.com repository.skong.com
#scp –a basic-repository.crt docker-IP:/etc/docker/cert.d/ basic-repository.skong.com
* 在传完证书的 docker 服务器上执行:
#mkdir –pv /etc/docker/cert.d/basic-repository.skong.com
#service docker restart
# docker login -u admin -p Harbor123456 repository.skong.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、启动 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. 当需要修改配置文件刷新配置时需要执行:#./prepare
Test:# docker login -u admin -p Harbor123456 repository.skong.com
# ls /etc/docker/certs.d/
#docker pull basic-registry.skong.com/skong/dubbo:latest
# docker images
#docker tag basic-registry.skong.com/skong/dubbo:latest repository.skong.com/basic/dubbo:latest
# docker push repository.skong.com/basic/dubbo:latest
