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：

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

下载文件

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

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

从 harbor 发布页面下载最新的 harbor 离线安装包

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

导入 docker images

导入离线安装包中 harbor 相关的 docker images：

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

创建 harbor nginx 服务器使用的 x509 证书

创建 harbor 证书签名请求：

$ cat > harbor-csr.json <<EOF
{
  "CN": "harbor",
  "hosts": [
    "127.0.0.1",
    "${NODE_IP}"
  ],
  "key": {
    "algo": "rsa",
    "size": 2048
  },
  "names": [
    {
      "C": "CN",
      "ST": "BeiJing",
      "L": "BeiJing",
      "O": "k8s",
      "OU": "4Paradigm"
    }
  ]
}
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：

$ cfssl gencert -ca=/etc/kubernetes/cert/ca.pem \
  -ca-key=/etc/kubernetes/cert/ca-key.pem \
  -config=/etc/kubernetes/cert/ca-config.json \
  -profile=kubernetes harbor-csr.json | cfssljson -bare harbor

$ ls harbor*
harbor.csr  harbor-csr.json  harbor-key.pem harbor.pem

$ sudo mkdir -p /etc/harbor/ssl
$ sudo mv harbor*.pem /etc/harbor/ssl
$ rm harbor.csr  harbor-csr.json

修改 harbor.cfg 文件

$ cp harbor.cfg{,.bak}
$ vim harbor.cfg
$ diff harbor.cfg{,.bak}
7c7
< hostname = 172.27.129.81
---
> hostname = reg.mydomain.com
11c11
< ui_url_protocol = https
---
> ui_url_protocol = http
23,24c23,24
< ssl_cert =  /etc/harbor/ssl/harbor.pem
< ssl_cert_key = /etc/harbor/ssl/harbor-key.pem
---
> ssl_cert = /data/cert/server.crt
> ssl_cert_key = /data/cert/server.key

$ cp prepare{,.bak}
$ vim prepare
$ diff prepare{,.bak}
453a454
>         print("%s %w", args, kw)
490c491
<     empty_subj = "/"
---
>     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

加载和启动 harbor 镜像

$ sudo mkdir /data
$ sudo chmod 777 /var/run/docker.sock /data
$ sudo apt-get install python
$ ./install.sh

[Step 0]: checking installation environment ...

Note: docker version: 18.03.0

Note: docker-compose version: 1.21.2

[Step 1]: loading Harbor images ...

Loaded image: vmware/postgresql-photon:v1.5.1
Loaded image: vmware/harbor-adminserver:v1.5.1
Loaded image: vmware/registry-photon:v2.6.2-v1.5.1
Loaded image: vmware/photon:1.0
Loaded image: vmware/harbor-migrator:v1.5.1
Loaded image: vmware/harbor-ui:v1.5.1
Loaded image: vmware/redis-photon:v1.5.1
Loaded image: vmware/nginx-photon:v1.5.1
Loaded image: vmware/mariadb-photon:v1.5.1
Loaded image: vmware/notary-signer-photon:v0.5.1-v1.5.1
Loaded image: vmware/harbor-log:v1.5.1

Loaded image: vmware/harbor-jobservice:v1.5.1
Loaded image: vmware/notary-server-photon:v0.5.1-v1.5.1


[Step 2]: preparing environment ...
loaded secret from file: /data/secretkey
Generated configuration file: ./common/config/nginx/nginx.conf
Generated configuration file: ./common/config/adminserver/env
Generated configuration file: ./common/config/ui/env
Generated configuration file: ./common/config/registry/config.yml
Generated configuration file: ./common/config/db/env
Generated configuration file: ./common/config/jobservice/env

The configuration files are ready, please use docker-compose to start the service.


[Step 3]: checking existing instance of Harbor ...


[Step 4]: starting Harbor ...
Creating network "harbor_harbor" with the default driver
Creating harbor-log ... done
Creating redis              ... done

✔ ----Harbor has been installed and started successfully.----

Now you should be able to visit the admin portal at https://172.27.129.81.

访问管理界面

确认所有组件都工作正常：

$ docker-compose  ps
       Name                     Command                  State                                    Ports

redis                docker-entrypoint.sh redis ...   Up             6379/tcp
registry             /entrypoint.sh serve /etc/ ...   Up (healthy)   5000/tcp

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

由于是在 virtualbox 虚机 kube-node2 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：

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 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。

$ # 日志目录
$ ls /var/log/harbor
adminserver.log  jobservice.log  mysql.log  proxy.log  registry.log  ui.log
$ # 数据目录，包括数据库、镜像仓库
$ ls /data/
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

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

登陆 harbor

$ docker login 172.27.129.81
Username: admin
Password:

认证信息自动保存到 ~/.docker/config.json 文件。

其它操作

下列操作的工作目录均为 解压离线安装文件后 生成的 harbor 目录。

$ # 停止 harbor
$ docker-compose down -v

$ # 修改配置
$ vim harbor.cfg

$ # 更修改的配置更新到 docker-compose.yml 文件
$ ./prepare
