Currently looking to migrate an old plone version to a containerized solution using the derived plone images plone/plone-backend - Docker Image | Docker Hub and plone/plone-frontend - Docker Image | Docker Hub.
I would like to know if these have been stress tested by anyone for production use?
In the documentation for the plone-backend image, I can see it's mentioned
We advise against using this feature on production environments.
However I believe that is referring to the use of the ADDONS environment variable as it needs permissions to interact with the site-packages folder of the installed python. Furthemore, when trying to use the ADDONS I am receiving permission errors, and I believe the issue was looked at here, however it's not clear as to whether the issue was fixed or not.
