# Allows copying of job files to local after execution. Example copy command:
#
#   kubectl apply -f ./export-file-job.yaml
#   POD=$(kubectl get pod --selector=job-name=export-files -o jsonpath='{.items[0].metadata.name}')
#   kubectl wait pod/$POD --for=condition=ready

#   kubectl cp $POD:files.zip ./job-files-$(date +"%Y%m%d%H%M").zip

# Another option would be for the `export-files` container to be a webserver to
# serve of the artifact files to be downloaded with `kubectl port-forward ...`.
