Change Timezone Jellyfin docker

2 months ago by thanksforallthefish to c/jellyfin

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 ?

Assuming your config and data files are in a data folder you mount into the container, no.

Thanks very much for the reply, yes the config and data are visible as directories from the NAS itself so I think it should be ok then. I'll back up the folder structure now.

Assuming you are storing the data on the Nas and not inside the container itself restarting the container is fine.

You can always duplicate the container with another name to test your changes.

Thanks very much for the reply, yes the config and data are visible as directories from the NAS itself so I think so.

I've just kicked over an ftp of the entire jellyfin structure as a back up - I'll duplicate the container as well for belt and braces

Thanks both, it worked, although I had a bit of a heart attack when it took a lot longer to come back up than I expected.

Now to try and work out how to get immich working.

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.

Hey thanks for the response, yes the storage is mounted via the compose script
