Thank you @erohmensing,
Under which of these do I implement it?
resources: {}
# additional volumeMounts to the main container
extraVolumeMounts: []
# - name: tmpdir
# mountPath: /var/lib/mypath
# additional volumes to the pod
extraVolumes: []
# - name: tmpdir
# emptyDir: {}
Also, how do I add these external files (they are available in my Github repo)?
Sorry for these simplistic questions, Docker/Kubernetes/Helm is relatively new to me!
