2 对挂载的存储修改所属组
mkdir -p /root/data/nfs/jenkins/devops
chown -R 1000 /root/data/nfs/jenkins/devops
3 执行如下命令创建Jenkins
kubectl apply -f jenkins.yaml
4 使用如下命令查看创建的Pod状态
kubectl get pod -n devops
5 在浏览器通过ip+端口访问,这里端口为30002
6 根据上面提示,使用如下命令查看密码
kubectl exec -it devops-jenkins-9d4555c89-xzz55 /bin/cat /var/jenkins_home/secrets/initialAdminPassword -n devops
7 复制上述密码,填入WEB登录页面
8 为了方便,这里可以选择推荐插件安装,如果自定义安装的话,需要对Jenkins的常用插件比较了解
9 然后设置管理员用户名密码等
10 确认Jenkins的Url
11 点击【开始使用Jenkins】
12 至此,Jenkins就安装完成了
