    使上面的内容生产证书

    1. 复制certificate-authority-data冒号后的内容生成client.crt
    2. # echo "<certificate-authority-data>" | base64 -d > ca.crt
    4. 复制client-certificate-data冒号后的内容生成client.crt
    5. # echo "<client-certificate-data>" | base64 -d > client.crt
    7. 复制client-key-data冒号后的内容生成client.key
    8. # echo "<client-key-data>" | base64 -d > client.key
    10. 再生成jenkins使用的PKCS12格式的cert.pfx文件，需要设置密码，注意密码后期jenkins需要
    12. # openssl pkcs12 -export -out cert.pfx -inkey client.key -in client.crt -certfile ca.crt
    13. Enter Export Password:        #输入自定义密码
    14. Verifying - Enter Export Password:        #验证密码

    jenkins使用证书创建凭证
    系统管理 > Manage Credentials（凭证）
    会看到如下页面，随便点击一个全局

    20211013091829804.png

    添加凭证
    20211013091905305.png

    按下图操作，类型注意选择为 Certificate，然后上传证书，输入当时生成证书的密码，最后确定，此时连接k8s集群的凭证就添加完成了fb72b79b-61d9-4757-9320-c73ce264f407.png
    关联到k8s20211013092006248.png

    jenkins下先安装kubernetes插件，名字就叫kubernetes

    安装期间可能有几个是失败的，没关系继续重启

    安装完成后到 系统管理 >jenkins管理>Configure Clouds
    image.png

    点 Configure Clouds 配置一个集群
    image.png

    地址也在最开始生成证书的 config 文件中

    kubernetes 服务证书 key 下是 ca.crt 中内容

    凭证选择上面创建的凭证

    配置完成后点击凭证下的测试连接

    出现你的集群版本信息表示配置成功了
