在 Kubernetes(k8s)中部署 jenkins
YAML 配置文件
因为 jenkins 须要长久化存储,通过 nfs 动静供应 pvc 存储卷。
能够参考我之前的文档:https://cloud.tencent.com/dev…
vim jenkins-deploy.yaml
cat jenkins-deploy.yaml

执行部署
kubectl apply -f jenkins-deploy.yaml
persistentvolumeclaim/jenkins-data-pvc created
serviceaccount/jenkins-admin created
clusterrolebinding.rbac.authorization.k8s.io/jenkins-admin created
deployment.apps/jenkins created
service/jenkins created
service/jenkins-agent created
