jenkins 添加 k8s 云

同事的jenkins 链接自己的 k8s 总是出问题 给出了资料和服务器 进行处理。

同时给出的参考资料：https://blog.csdn.net/diantun00/article/details/81180694

这边用自己的服务器简单进行了测试。

jenkins的地址

http://10.24.101.161:8080/configure

k8s 集群的

https://10.24.103.1:6443

1. 验证jenkins 已经添加了 kubernetes 的插件

如果没有的话自行安装

然后 进行系统配置

拖到最后面 添加一个云

我的k8s 是使用 kubeadm 直接 安装的 比较简单， 根据 作者的说法进行处理

进入 kubernetes的配置目录

cd /etc/kubernetes

查看 admin.conf

cat admin.conf

我这边的内容为：

反正是测试服务器---说不定明天我就删了-- 证书 密钥 无所谓。。。

|base64 -d >ca.crt

原作者写的更好， 这里直接copy了

用到上面提到的kubernetes的配置文件

文件中有三个值 certificate-authority-data 、client-certificate-data 、 client-key-data 

解码它们获得证书 ，注意将上面的值替换称自己的一大长传字符串

echo certificate-authority-data | base64 -d > ca.crt
echo client-certificate-data | base64 -d > client.crt
echo client-key-data | base64 -d > client.key

然后根据如上内容生成客户端认账的 证书

openssl pkcs12 -export -out cert.pfx -inkey client.key -in client.crt -certfile ca.crt

注意导出时收入输入密码。

这里完整的复制的原作者的内容 openssl 的使用虽然之前学过 但是太不精通了。。

然后k8s 里面进行处理

将 ca.crt base64 解码之后的证书内容放进来

如图示

 然后添加jenkins的证书

选择 证书

 然后 上传 文件 输入导出时的密码

然后 进行测试

能够成功。

管理jenkins的凭据

不知道怎么删除。。。
