I did run the ghcr.io/logseq/logseq-webapp:latest locally and it seems it is configured to use a local folder that the user defines on first startup… the folder is accessed via FileSystem API … so no webserver storage
I would also love to host a docker-service logseq … to share notes with my co-workers… but cannot find (by now) a solution
but here is a discussion about it Local (on-server) storage for self-hosted Logseq
