Docker containter is not stateless

The file /app/lib/tzdata-1.1.2/priv/latest_remote_poll.txt at docker startup.
It will stopped the deployment on Kubernetes/OpenShift as the folder /app/lib/tzdata-1.1.2/priv is read only.

To let it work the following Dockerfile should be used:

FROM openfn/lightning:v2.10.7
RUN chmod -R a+rwX /app/lib/tzdata-1.1.2/priv/

A solution could be to write this file to /app/priv/static or to the cache folder /.npm
