部署Harbor镜像仓库并在k8s配置使用

---

一、下载所需软件包

1.docker-compose

docker-compose地址：https://github.com/docker/compose/releases/

[root@iZbp135usqaei1stvsrzxoZ fands]# wget -c https://github.com/docker/compose/releases/download/v2.9.0/docker-compose-linux-x86_64

2.harbor

harbor官方地址：https://goharbor.io/
harbor github地址：https://github.com/goharbor/harbor

[root@iZbp135usqaei1stvsrzxoZ fands]# wget -c https://github.com/goharbor/harbor/releases/download/v2.4.2/harbor-offline-installer-v2.4.2.tgz

二、安装docker-compose

1.安装docker

[root@iZbp135usqaei1stvsrzxoZ ~]# wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
[root@iZbp135usqaei1stvsrzxoZ ~]# yum -y install docker-ce
[root@iZbp135usqaei1stvsrzxoZ ~]# systemctl enable docker && systemctl start docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@iZbp135usqaei1stvsrzxoZ ~]# systemctl status docker 

2.配置docker-compose

[root@iZbp135usqaei1stvsrzxoZ fands]# mv docker-compose-linux-x86_64 /usr/bin/docker-compose
[root@iZbp135usqaei1stvsrzxoZ fands]# chmod +x /usr/bin/docker-compose 
[root@iZbp135usqaei1stvsrzxoZ fands]# docker-compose -v 
Docker Compose version v2.9.0

三、安装harbor

[root@iZbp135usqaei1stvsrzxoZ fands]# tar -zxvf harbor-offline-installer-v2.4.2.tgz -C /hqtbj/hqtwww/
[root@iZbp135usqaei1stvsrzxoZ fands]# cd /hqtbj/hqtwww/
[root@iZbp135usqaei1stvsrzxoZ hqtwww]# mv harbor harbor_workspace
[root@iZbp135usqaei1stvsrzxoZ hqtwww]# cd harbor_workspace/
[root@iZbp135usqaei1stvsrzxoZ harbor_workspace]# cp harbor.yml.tmpl harbor.yml

1.编辑harbor配置文件

[root@iZbp135usqaei1stvsrzxoZ harbor_workspace]# vim harbor.yml
#harbor的域名
hostname: registry.xxxx.cc
#默认http
http:
  port: 80
#开启https访问
https:
  port: 443
  #支持泛域名证书(例如：*.xxxx.cc.pem)
  certificate: /hqtbj/hqtwww/harbor_workspace/ssl/registry.xxxx.cc.pem
  private_key: /hqtbj/hqtwww/harbor_workspace/ssl/registry.xxxx.cc.key
#数据存放目录（实际存放镜像的地方，需要备份好）
data_volume: /hqtbj/hqtwww/data/harbor
...

2.加载harbor配置（重新加载配置文件，只要修改配置文件就需要执行）

[root@iZbp135usqaei1stvsrzxoZ harbor_workspace]# ./prepare 

3.开始安装harbor

只需要要在首次安装时执行，若重复执行则将丢失所有已有景象，慎重！！

[root@iZbp135usqaei1stvsrzxoZ harbor_workspace]# ./install.sh

安装完成后会在当前目录下出现一个docker-compose.yml文件，主要用于管理harbor这些容器的

4.docker-compose 命令启动/停止harbor

需要进入harbor工作目录下执行(含有docker-compose.yaml文件的目录)

#停止harbor所有容器
docker-compose stop
#启动harbor所有容器
docker-compose up -d 

四、配置nginx代理harbor

server {
        listen  80;
        server_name  registry.xxxx.cc;
        rewrite ^(.*)$  https://$host$1 permanent;
        }

server {
        listen 443 ssl;
        server_name  registry.xxxx.cc;
        location / {
          proxy_pass https://172.32.0.175:443;
        }
        
        #支持泛域名证书(例如：*.xxxx.cc.pem)
        ssl_certificate /etc/nginx/conf.d/cert/xxxx.cc/master/registry.xxxx.cc.pem;
        ssl_certificate_key /etc/nginx/conf.d/cert/xxxx.cc/master/registry.xxxx.cc.key;
        ssl_session_timeout 5m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
        ssl_prefer_server_ciphers on;
      }

通过域名访问：

默认用户名admin
默认密码Harbor12345

创建项目空间存放镜像

五、kubernetes配置harbor镜像仓库

1.创建harbor的secrets用于拉取镜像的凭证

#这里生成的secrets是访问harbor的用户名密码

[root@k8s-master1 ~]# kubectl create secret docker-registry --help

[root@k8s-master1 ~]# kubectl create secret docker-registry fatall-registry-secret --docker-username=admin --docker-password=123456 --docker-server=https://registry.xxxx.cc -n fat

[root@k8s-master1 ~]# kubectl get secrets -n fat
NAME                                        TYPE                                  DATA   AGE
default-token-ktkdt                               kubernetes.io/tls                     2      474d
fatall-registry-secret                      kubernetes.io/dockerconfigjson        1      12m

2.配置deployment拉取私有镜像时使用的secerts凭证

官网配置如下：
https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/#add-imagepullsecrets-to-a-service-account
主要是在下载镜像时添加如下内容：

apiVersion: apps/v1
kind: Deployment
...
    spec:
      #设置下载harbor私有镜像时用的凭证
      imagePullSecrets:
        - name: fatall-registry-secret
      containers:
      - name: energy-order-api
        image: registry.xxxx.cc/hqt-registry-fat/energy-order-api:F-2153-20240703-18.37.52
        imagePullPolicy: IfNotPresent
