The sample defined in 

https://github.com/jenkinsci/kubernetes-plugin/blob/master/src/main/resources/org/csanchez/jenkins/plugins/kubernetes/pipeline/samples/maven.groovy

Does not specify any kind of request and limit.

In resource limited environments it could fail due to OOM events.

We have reproduced this issue by running it in a pod with memoty limited to 256Mi.

We need to proper handle it by including resource requests and limits for memory.

Valid values can be:

spec:
  containers:
  - resources:
      requests:
        memory: "256Mi"
      limits:
        memory: "512Mi"
