k8s中安装jenkins

时间:2022-12-12 11:56:23

编写jenkins.yaml

说明:

  容器跑起来后,jenkins的目录是/var/jenkins_home

  存储卷用的是hostPath,这里面我们指定pod调度到k8s-master01

在k8s-master01上创建目录:mkdir /data_jenkins

创建名称空间:kubectl create ns jenkins

jenkins.yaml

另外,jenkins在容器中的uid是1000,赋予其宿主机上目录的权限:chown -R 1000.1000 /data_jenkins

创建资源

应用资源文件:kubectl apply -f jenkins.yaml

查看pod:kubectl get po -n jenkins -owide

查看svc:kubectl get svc -n jenkins

通过k8s集群任意一个节点访问:192.168.117.161:30667

 

进入容器查看密码:

kubectl exec -it -n jenkins po/jenkins-dd6c9cdcd-m9964 -- sh

 密码是: 1e45bee7642d44e3acd5e9563f1bebf2

也可以在宿主机上查看密码:
