配置 Jenkins 连接 Kubernetes 集群

需求:外部 Jenkins 需要连接 Rancher 中的 Kubernetes 集群。

1、集群 config 文件

Rancher 首页,"集群" --> 右上角"Kubeconfig 文件",后续需要用到该文件内容。

apiVersion: v1
kind: Config
clusters:
- name: "cicd"
  cluster:
    server: "https://rancher.xxxxxx.com/k8s/clusters/c-b5g7r"
- name: "cicd-dev-cicd-k8s-master"
  cluster:
    server: "https://172.16.5.83:6443"
    certificate-authority-data: "LS0tLSerashtyjyurkilyrderhaURS0tLS0tCk1JSUN3akNDQ\
      WFxZ0F3SUJBZ0lCQURBTkJna3Foa2lHOXcwQkFRc0ZBREFTTVJBd0RnWURWUVFERXdkcmRXSmwKT\
      FdOaE1CNFhEVEU1TURnd05UQTJORFl6TWsdfgRUSTVNRGd3TWpBMk5EWXpNbG93RWpFUU1BNEdBM\
      VVFQXhNSAphM1ZpWlMxallUQ0NBU0l3RFFZSktvWklodmNOQVFFQkJRQURnZ0VQQURDQ0FRb0NnZ\
      GFiSXpBMC9KOE5GaDZQektYVWNKTApMZE1RQkUrOTBJbStBaWZRWENuaG9iRUZEYWh6ZDkyeFArU\
      1RYTlZsK0Q3RDBlUFVyRjdoUExKdENWL2lPekxYCmxLLzRUTzZmVG1XZmo2NlBqRXk5djB5OHpxT\
      DhDazVKem9jTDkzZDlVSnZPTmtjdy8wRHk0SVVJMHlBZnRmb3IKaUJmbXh4K0ZnK2hRK0xMZEN1M\

      mlia1NSVHhMc0t5S3FyRXZ0Y3Zldnd4enM0OTlRbWlFZmI3dmxucXM9Ci0tLS0tRU5EIENFUlRJR\
      klDQVRFLS0tLS0K"

users:
- name: "u-42lyr7ytst"
  user:
    token: "kubeconfig-u-42lyr7ytst.c-b5g7r:45kclvgd4bh87rtvtpbqhwhf7s62fqpl"

contexts:
- name: "cicd"
  context:
    user: "u-42lyr7ytst"
    cluster: "cicd"
- name: "cicd-dev-cicd-k8s-master"
  context:
    user: "u-42lyr7ytst"
    cluster: "cicd-dev-cicd-k8s-master"

current-context: "cicd"

 

2、新建凭据

新建一个连接 kubernetes 集群的凭据

1)类型:Secret text
2)范围:全局
3)Secret:confi文件中的token值
4)id:kube(自定义命名)

 

3、配置kubernetes云

系统设置 --> 增加一个云(kubernetes)

1)名称:kubernetes
2)Kubernetes地址:https://rancher.xxxxxx.com/k8s/clusters/c-xg99q
3)Kubernetes服务证书key:config文件中的certificate-authority-data值,但是这个值需要进行转换,命令:echo xxxxxxxxx | base64 -d >ca.crt
4)凭据:之前创建的凭据
5)Jenkins地址:http://jenkinscicd.xxxxxx.com

连接测试提示:Connection test successful,即表示连接成功。
