Harbor镜像仓库安装配置

###安装脚本###

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
yum makecache fast
yum -y install docker-ce

###配置镜像加速器###

mkdir /etc/docker/
vi /etc/docker/daemon.json

{
  "live-restore": true,
  "registry-mirrors": ["https://hub-mirror.c.163.com", "https://bmtrgdvx.mirror.aliyuncs.com", "http://f1361db2.m.daocloud.io"],
  "log-driver": "json-file",
  "log-opts": {"max-file": "3", "max-size": "10m"}
}

###重启服务###

systemctl enable docker
systemctl start docker

curl -L https://get.daocloud.io/docker/compose/releases/download/v2.1.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

###上传harbor安装包###

tar -zxvf harbor-offline-installer-v2.4.0.tgz
mv harbor /usr/local/
cd /usr/local/harbor/

###生成harbor的密钥###

openssl genrsa -out docker.com.key 2048
openssl req -new -key docker.com.key -out docker.com.csr -subj "/CN=192.168.20.72" ###此为harbor服务器的IP地址
openssl x509 -req -days 3650 -in docker.com.csr -signkey docker.com.key -out docker.com.crt


####创建日志目录###

mkdir -p /var/log/harbor

cp harbor.yml.tmpl harbor.yml
vim harbor.yml

###只需要修改主机名字段对应的Ip地址，证书存放位置即可。

执行./install.sh

安装完成如下图：

 通过web登录：（默认账号密码：admin/Harbor12345）

vim /usr/lib/systemd/system/docker.service

注释ExecStart行，新增以下内容(地址为harbor地址)：

ExecStart=/usr/bin/dockerd --insecure-registry 192.168.20.72

systemctl daemon-reload

systemctl restart docker

docker login https://192.168.20.72

docker pull nginx:latest

docker image inspect nginx | grep -i version

docker tag nginx:latest 192.168.20.72/prod/nginx:v1.21.3

docker push 192.168.20.72/prod/nginx:v1.21.3

登录web进行查看：

参考本文章第6部分内容，为每个master和woker节点修改配置文件，确保每个节点均能login。

# 以下命令在master节点执行

# 创建用于登陆harbor的secret

# 注意修改IP地址和用户/密码

kubectl create secret docker-registry harbor-secret 
--docker-server=192.168.20.72 --docker-username=admin 
--docker-password=P@ssw0rd

# 查看创建的secret

kubectl get secret

# 查看serviceaccount

kubectl get sa

# 指定serviceaccount的secret为harbor的secret

kubectl patch serviceaccount default -p '{"imagePullSecrets": [{"name": "harbor-secret"}]}'

# 查看是否修改成功

kubectl describe  sa default
