I'm begginer in Kubernetes and trying to deploy Jenkins in a cluster, but the pod is getting pending.

I need jenkins with access to kubernetes, including access to docker and kubectl commands, for continuos integration with my microservices.

With this example yaml file, I can start a jenkins instance on a local machine (my notebook) through Minikube.

But now I'm trying to use a cloud cluster as part of my field of study.

I accept suggestions for improvements.

As I said: I just want to upload an instance of jenkins, with which I can continually integrate my micro services.

These are my configs and logs.

What is my mistake?

        persistentVolumeClaim:
          claimName: jenkins-claim

Then kubectl --context do-sfo2-teste-cluster apply -f jenkins.yaml

But is allways pending:
