11.部署 harbor 私有仓库

本文档介绍使用 docker-compose 部署 harbor 私有仓库的步骤，你也可以使用 docker 官方的 registry 镜像部署私有仓库(部署 Docker Registry)。

使用的变量

本文档用到的变量定义如下：

  1. $ export NODE_IP=10.64.3.7 # 当前部署 harbor 的节点 IP
  2. $

下载文件

从 docker compose 发布页面下载最新的 docker-compose 二进制文件

  1. $ wget https://github.com/docker/compose/releases/download/1.21.2/docker-compose-Linux-x86_64
  2. $ mv ~/docker-compose-Linux-x86_64 /opt/k8s/bin/docker-compose
  3. $ chmod a+x  /opt/k8s/bin/docker-compose
  4. $ export PATH=/opt/k8s/bin:$PATH
  5. $

从 harbor 发布页面下载最新的 harbor 离线安装包

  1. $ wget  --continue https://storage.googleapis.com/harbor-releases/release-1.5.0/harbor-offline-installer-v1.5.1.tgz
  2. $ tar -xzvf harbor-offline-installer-v1.5.1.tgz
  3. $

导入 docker images

导入离线安装包中 harbor 相关的 docker images：

  1. $ cd harbor
  2. $ docker load -i harbor.v1.5.1.tar.gz
  3. $

创建 harbor nginx 服务器使用的 x509 证书

创建 harbor 证书签名请求：

  1. $ cat > harbor-csr.json <<EOF
  2. {
  3.   "CN": "harbor",
  4.   "hosts": [
  5.     "127.0.0.1",
  6.     "${NODE_IP}"
  7.   ],
  8.   "key": {
  9.     "algo": "rsa",
  10.     "size": 2048
  11.   },
  12.   "names": [
  13.     {
  14.       "C": "CN",
  15.       "ST": "BeiJing",
  16.       "L": "BeiJing",
  17.       "O": "k8s",
  18.       "OU": "4Paradigm"
  19.     }
  20.   ]
  21. }
  22. EOF
  • hosts 字段指定授权使用该证书的当前部署节点 IP，如果后续使用域名访问 harbor 则还需要添加域名；

生成 harbor 证书和私钥：

  1. $ cfssl gencert -ca=/etc/kubernetes/cert/ca.pem \
  2.   -ca-key=/etc/kubernetes/cert/ca-key.pem \
  3.   -config=/etc/kubernetes/cert/ca-config.json \
  4.   -profile=kubernetes harbor-csr.json | cfssljson -bare harbor
  6. $ ls harbor*
  7. harbor.csr  harbor-csr.json  harbor-key.pem harbor.pem
  9. $ sudo mkdir -p /etc/harbor/ssl
  10. $ sudo mv harbor*.pem /etc/harbor/ssl
  11. $ rm harbor.csr  harbor-csr.json

修改 harbor.cfg 文件

  1. $ cp harbor.cfg{,.bak}
  2. $ vim harbor.cfg
  3. $ diff harbor.cfg{,.bak}
  4. 7c7
  5. < hostname = 172.27.129.81
  6. ---
  7. > hostname = reg.mydomain.com
  8. 11c11
  9. < ui_url_protocol = https
  10. ---
  11. > ui_url_protocol = http
  12. 23,24c23,24
  13. < ssl_cert =  /etc/harbor/ssl/harbor.pem
  14. < ssl_cert_key = /etc/harbor/ssl/harbor-key.pem
  15. ---
  16. > ssl_cert = /data/cert/server.crt
  17. > ssl_cert_key = /data/cert/server.key
  19. $ cp prepare{,.bak}
  20. $ vim prepare
  21. $ diff prepare{,.bak}
  22. 453a454
  23. >         print("%s %w", args, kw)
  24. 490c491
  25. <     empty_subj = "/"
  26. ---
  27. >     empty_subj = "/C=/ST=/L=/O=/CN=/"

  • 需要修改 prepare 脚本的 empyt_subj 参数，否则后续 install 时出错退出：

    Fail to generate key file: ./common/config/ui/private_key.pem, cert file: ./common/config/registry/root.crt

浏览器访问 https://${NODE_IP}，示例的是 https://172.27.129.81；

由于是在 virtualbox 虚机 zhangjun-k8s02 中运行，所以需要做下端口转发，Vagrant 文件中已经指定 host 端口为 4443，也可以在 virtualbox 的 GUI 中直接添加端口转发：

virtualbox-harbor

浏览器访问 https://127.0.0.1:443，用账号 admin 和 harbor.cfg 配置文件中的默认密码 Harbor12345 登陆系统。

harbor

harbor 运行时产生的文件、目录

harbor 将日志打印到 /var/log/harbor 的相关目录下，使用 docker logs XXX 或 docker-compose logs XXX 将看不到容器的日志。

  1. $ # 日志目录
  2. $ ls /var/log/harbor
  3. adminserver.log  jobservice.log  mysql.log  proxy.log  registry.log  ui.log
  4. $ # 数据目录，包括数据库、镜像仓库
  5. $ ls /data/
  6. ca_download  config  database  job_logs registry  secretkey

docker 客户端登陆

将签署 harbor 证书的 CA 证书拷贝到 /etc/docker/certs.d/172.27.129.81 目录下

  1. $ sudo mkdir -p /etc/docker/certs.d/172.27.129.81
  2. $ sudo cp /etc/kubernetes/cert/ca.pem /etc/docker/certs.d/172.27.129.81/ca.crt
  3. $

登陆 harbor

  1. $ docker login 172.27.129.81
  2. Username: admin
  3. Password:

认证信息自动保存到 ~/.docker/config.json 文件。
