詹金斯在库伯内特斯的持续音量

Question

我试图在本地库伯内特斯集群上部署詹金斯映像。部署成功，但我无法让持久性数据工作。没有错误被抛出，新豆荚成功启动，唯一的问题是它不持久。

FROM jenkins/jenkins:lts

ENV JENKINS_USER admin
ENV JENKINS_PASS admin

# Skip initial setup
ENV JAVA_OPTS -Djenkins.install.runSetupWizard=false

持续批量索赔

我在用Minikube进行本地开发。当然还有库贝特。

别看我做错了什么。感谢您的帮助。

常规dockerhub jenkins映像使用路径/var/jenkins_home，而不是/var/lib/jenkins来获取持久数据。因此，应该使用该路径装载持久卷。
