Jenkins kubernetes Client

[Sudha Subramanian]

Hi,

I'm trying to run Jenkins in kubernetes with 'kubernetes-client' plugin for dynamic slaves. I get the following error:

Caused by: java.text.ParseException: failed to load settings from jar:file:/var/jenkins_home/war/WEB-INF/lib/groovy-all-2.4.7.jar!/groovy/grape/defaultGrapeConfig.xml: impossible to add configured child for ivy on class org.apache.ivy.plugins.resolver.FileSystemResolver: ivy pattern must be absolute: ?/.groovy/grapes/[organisation]/[module]/ivy-[revision].xml

The same Jenkins image runs on my mac without any issues. Has anyone encountered this issue running Jenkins in Kubernetes with the client plugin enabled?

Thanks,

Sudha

I recently setup jenkins using the `kubernetes-plugin` and didn't have any issues like this.

Where/when do you get this error? what's your kubernetes yaml file look like?

This is the core part of my jenkins.yml file

 

 containers:

    - name: jenkins-tnrp-master

      image: tnrp/jenkins:2.32.3

      ports:

      - containerPort: 8080

      - containerPort: 50000

      resources:

        limits: { cpu: "10", memory: "20Gi" }

        requests: { cpu: "10", memory: "20Gi" }

      volumeMounts:

        - mountPath: /var/jenkins_home

          name: jenkins-data

      livenessProbe:

        httpGet:

          path: /

          port: 8080

        initialDelaySeconds: 5

    volumes:

      - name: jenkins-data

        emptyDir: {}

I get this error when it is trying to start Jenkins. My Dockerfile for creating the jenkins image looks like this:

FROM jenkins

RUN /usr/local/bin/install-plugins.sh kubernetes:0.11 workflow-aggregator:2.5 credentials-binding:1.10 git:3.2.0 \

    && mkdir -p /usr/share/jenkins/ref/secrets/ \

    && echo "false" > /usr/share/jenkins/ref/secrets/slave-to-master-security-kill-switch

ah, ok so you're using a custom jenkins image. I assume you don't get this error when using the generic jenkins image? and then does it work ok if you take out the install-plugins script from your custom image? 

(to be honest, I don't have any experience with this approach or this error, just trying to help you pinpoint what the actual problem is)
