Failed to set TZ, due to tzdata missing from image

dittodhole commented 1 month ago

Hi, and thanks for this sleek docker image ❤️

When setting env TZ to eg Europe/Vienna the container fails to start, as the timezone is missing. I've also tried to utilize command: bash -c "apk add tzdata", but this fails in minidlna.c:830.

Any chance to add tzdata to https://github.com/vladgh/docker_base_images/blob/main/minidlna/Dockerfile#L7?

Best Andreas

HI Andreas, I cannot replicate this. Seems to work fine. Alpine has it's own tzdata scripts, called by this image at the beginning, and as long as the time zone is a string that exists in the database, it should work. May I ask how are you defining the env?

services:
  minidlna:
    container_name: minidlna
    image: vladgh/minidlna
    restart: unless-stopped
    hostname: minidlna
    environment:
      TZ: Europe/Vienna
      PUID: 1000
      PGID: 1000
      MINIDLNA_MEDIA_DIR_1: A,/mnt/music
      MINIDLNA_FRIENDLY_NAME: minidlna
    volumes:
      - type: bind
        source: /media/music
        target: /mnt/music
        read_only: true

Output of the container:

=== Set user and group identifier === Set timezone 'Europe/Vienna' is not a valid timezone on this system

I even consoled into the container, to list the available timezones:

minidlna:/# cat /etc/os-release NAME="Alpine Linux" ID=alpine VERSION_ID=3.20.0_alpha20240315 PRETTY_NAME="Alpine Linux edge" HOME_URL="https://alpinelinux.org/" BUG_REPORT_URL="https://gitlab.alpinelinux.org/alpine/aports/-/issues" minidlna:/# ls /usr/share/zoneinfo ls: /usr/share/zoneinfo: No such file or directory

That exact compose file gives me:

=== Set user and group identifier
=== Set timezone
=== Set standard configuration
=== Set configuration from environment variables
=== Set permissions
=== Generate scan/rebuild flags
=== Start daemon
minidlna.c:1134: warn: Starting MiniDLNA version 1.3.3.

minidlna.c:1182: warn: HTTP listening on port 8200
playlist.c:135: warn: Parsing playlists...
playlist.c:269: warn: Finished parsing playlists.

The only thing I can think of is to do a docker pull vladgh/minidlna:latest maybe you have a really old version of my image, before it had time zone support.

Nope, still same error 😢

And they said Docker will eliminate the "It works on my computer" problem 😡

I will look into it some more, but for now, I'm not sure what to tell you.

dittodhole commented 1 month ago

Thanks for your assistance! Really appreciate it ❤️

Is there anything I can fiddle around to give you a better insight "on my machine"?

vladgh commented 1 month ago

Remove the image completely, all versions, and pull it again. Maybe try to run it somewhere else, a different VM or machine.

Thanks for the suggestions, I did so with my current setup - but did not help.

Anyway, I just mounted /usr/share/zoneinfo, which fixed the problem:

fyi - when running network_mode: host instead of attaching the container to a macvlan, the tzdata package gets installed.

vladgh / docker_base_images

Failed to set TZ, due to tzdata missing from image #296
