用harbor搭建自己的镜像库

节点一：Ubuntu 20.04.4  harbor+docker   节点二：Ubuntu 20.04.4  kerbernetes集群的master节点

harbor版本包：harbor-offline-installer-v2.5.0.tgz

1、解压harbor包，cd  harbor目录

2、harbor默认配置文件示例是这个harbor.yml.tmpl，复制一份修改

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

 1 hostname: reg.k8smaster.org
 2 
 3 http:
 4   port: 80
 5 
 6 https:
 7   port: 443
 8   certificate: /data/certs/k8smaster.org.crt
 9   private_key: /data/certs/k8smaster.org.key

13 database:
14   password: root123
15   max_idle_conns: 100
16   max_open_conns: 900

18 data_volume: /data

20 trivy:
21   ignore_unfixed: false
22   skip_update: false
23   offline_scan: false
24   insecure: false
25 
26 jobservice:
27   max_job_workers: 10
28 
29 notification:

32 chart:
33   absolute_url: disabled
34 log:

38     rotate_size: 200M

46   no_proxy:
47   components:

49     - jobservice
50     - trivy
51 
52 upload_purging:
53   enabled: true
54   age: 168h
55   interval: 24h
56   dryrun: false

 

3、生成自签名证书

openssl req -newkey rsa:4096 -nodes -sha256 -keyout /data/certs/k8smaster.org.key -addext "subjectAltName = DNS:reg.k8smaster.org" -x509 -days 365 -out /data/certs/k8smaster.org.crt

root@kubemaster:/data/certs# ll
total 32
drwxr-xr-x 2 root root 4096 Jun 16 22:12 ./
drwxr-xr-x 9 root root 4096 May 5 22:39 ../
-rw-r--r-- 1 root root 2082 Jun 16 22:12 harbor.org.crt
-rw------- 1 root root 3272 Jun 16 22:08 harbor.org.key
-rw-r--r-- 1 root root 2175 May 5 22:39 k8smaster.org.crt
-rw------- 1 root root 3272 May 5 22:37 k8smaster.org.key
-rw-r--r-- 1 root root 2191 May 5 22:23 mydomain.com.crt
-rw------- 1 root root 3272 May 5 22:21 mydomain.com.key

 

4、安装harbor

cd harbor目录

./install.sh --with-notary --with-trivy --with-chartmuseum

成功就这样：

 

 

5、添加域名到hosts文件

6、web测试  harbor服务器ip，登录进来就这样吧

 

6、使用docker上传镜像时需要配置证书

mkdir -p /etc/docker/certs.d/reg.k8smaster.org

cp /data/certs/k8smaster.org.crt /etc/docker/certs.d/reg.k8smaster.org

docker login reg.k8smaster.org  #命令行上传之前西安登录harbor

 

7、harbor镜像的上传zabbix为例

docker search  zabbix

docker pull zabbix/zabbix-agent

docker tag  zabbix/zabbix-agent:latest reg.k8smaster.org/library/zabbix/zabbix-agent:latest

docker push reg.k8smaster.org/library/zabbix/zabbix-agent:latest

传完仓库就这样

 

 

7，k8s的容器访问harbor配置

k8s节点上操作，使用containerd容器

# mkdir -p /etc/containerd/certs.d/reg.k8smaster.org

# scp harbor服务器ip:/data/certs/k8smaster.org.crt /etc/containerd/certs.d/reg.k8smaster.org 

# vim /etc/containerd/config.toml [plugins."io.containerd.grpc.v1.cri".registry] config_path = "/etc/containerd/certs.d"  #指定证书路径

# systemctl restart containerd

# crictl pull reg.k8smaster.org/library/nginx:latest  #测试拉取镜像

 

8、

报错一截图；原因：docker没有login

 

报错二截图；原因：docker没有导证书

 

 

问题三：K8s节点上拉取镜像不加前缀，直接拉取镜像名称（设置默认仓库）的配置

# mkdir -p /etc/containerd/certs.d/docker.io

# vim /etc/containerd/certs.d/docker.io/hosts.toml server = "https://registry-1.docker.io" [host."https://reg.westos.org"] capabilities = ["pull", "resolve", "push"] skip_verify = true
