volumeMount: mountPath value considered as a directory about helm-charts

[henryrecker-pingidentity]

Rather than using configMapVolumes, You can directly define volumes and volumeMounts for workloads using the Helm chart. Something like this:

pingaccess-engine:
  enabled: true
  volumeMounts:
  - name: "pa-log4j-config"
    mountPath: "/opt/out/instance/conf/log4j2.xml"
    subPath: "pa-log4j-config"
  volumes:
  - name: "pa-log4j-config"
    configMap:
      name: "pa-log4j-config"

This will mount a single file from a configmap.

However the Kubernetes documentation indicates that configmap files mounted as subpaths (which is needed to mount single files from configmaps) do not update automatically when the configmap changes. https://kubernetes.io/docs/concepts/configuration/configmap/#mounted-configmaps-are-updated-automatically

So you would still need to restart the pod in this case, or manually update the file on the pod.
