和我一步步部署 kubernetes 集群

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/1.12.0/docker-compose-Linux-x86_64
$ mv ~/docker-compose-Linux-x86_64 /root/local/bin/docker-compose
$ chmod a+x  /root/local/bin/docker-compose
$ export PATH=/root/local/bin:$PATH
$

从 harbor 发布页面下载最新的 harbor 离线安装包

$ wget  --continue https://github.com/vmware/harbor/releases/download/v1.1.0/harbor-offline-installer-v1.1.0.tgz
$ tar -xzvf harbor-offline-installer-v1.1.0.tgz
$ cd harbor
$

导入 docker images

导入离线安装包中 harbor 相关的 docker images：

$ docker load -i harbor.v1.1.0.tar.gz
$

创建 harbor nginx 服务器使用的 TLS 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": "System"
    }
  ]
}
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/ssl/ca.pem \
  -ca-key=/etc/kubernetes/ssl/ca-key.pem \
  -config=/etc/kubernetes/ssl/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

$ diff harbor.cfg.orig harbor.cfg
5c5
< hostname = reg.mydomain.com
---
> hostname = 10.64.3.7
9c9
< ui_url_protocol = http
---
> ui_url_protocol = https
24,25c24,25
< ssl_cert = /data/cert/server.crt
< ssl_cert_key = /data/cert/server.key
---
> ssl_cert = /etc/harbor/ssl/harbor.pem
> ssl_cert_key = /etc/harbor/ssl/harbor-key.pem

加载和启动 harbor 镜像

$ ./install.sh
[Step 0]: checking installation environment ...

Note: docker version: 17.04.0

Note: docker-compose version: 1.12.0

[Step 1]: loading Harbor images ...

Loaded image: photon:1.0
Loaded image: vmware/notary-photon:server-0.5.0
Loaded image: vmware/notary-photon:signer-0.5.0


[Step 2]: preparing environment ...
Generated and saved secret to 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

Generated configuration file: ./common/config/ui/app.conf
Generated certificate, key file: ./common/config/ui/private_key.pem, cert file: ./common/config/registry/root.crt
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
Creating registry
Creating harbor-adminserver
Creating harbor-db
Creating harbor-ui
Creating harbor-jobservice
Creating nginx

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

Now you should be able to visit the admin portal at https://10.64.3.7.
For more details, please visit https://github.com/vmware/harbor .

访问管理界面

浏览器访问 https://${NODE_IP}，示例的是 https://10.64.3.7

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

$ # 日志目录
$ ls /var/log/harbor/2017-04-19/
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/10.64.3.7 目录下

$ sudo mkdir -p /etc/docker/certs.d/10.64.3.7
$ sudo cp /etc/kubernetes/ssl/ca.pem /etc/docker/certs.d/10.64.3.7/ca.crt
$

登陆 harbor

$ docker login 10.64.3.7
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
