I've run up a copy of Jellyfin in docker on a cheap NAS about a month ago. Seem to have mostly sorted out the wrinkles. First time running docker or jellyfin (all my other selfhosting has been on bare metal not using docker).

ONE issue: Timezone (daylight saving).

The NAS host OS is correctly showing the local TZ with 1 hour shift post daylight saving at the end of March - I checked at a command prompt (it's a tweaked version of debian) that it's showing correctly.

The Docker container however is showing the base time before daylight saving (ie UTC vs UTC+1)

I've just worked through how to change the docker compose file to pick up the correct TZ ie putting a

TZ: "Europe/London"

In the compose file (Project, settings, compose configuration)

BUT

When I go to apply it (redeploy button), it gives me a warning that makes me nervous to push it out.

"Redeployment will delete unneeded containers and images"

Soooo...will hitting deploy wipe out all the configuration I've done and the days worth of indexing all the media the server has done ? Or am I being overly nervous ?

Are you mounting a drive for the storage via the docker compose script or are you saving everything, including your jellyfin database, inside the docker container? If mounted storage then you’re fine. If not, then yeah wiping the container and recreating it will bin everything and start from scratch.
