Hello, we currently have Zammad running on a VServer.
But I want to install Akeneo as the 2nd websystem. Both require Elasticsearch so I would like to let them both run in their own container with Docker.
My question is what data we run in volumes that must be available after an update or reboot.
The Postgresql directory I would say in any case.
Letsencrypt could you get over it?
Elasticsearch also refreshes itself so often, so you could leave it that way, right?
