How to Set Timezone in Docker Container via Docker-Compose

[piyushpranjal03]

Question

Hi everyone,

I am using a docker compose file to run mediamtx image on raspberry-pi 4b. My local pi timezone is Asia/Kolkata but the docker default timezone is UTC and because of this all videos names are generated according to UTC timezone.

I tried to setup TZ=Asia/Kolkata as an enviroment variable in docker compose file but seems like that is not picked up by mediamtx image while running the docker-compose up -d.

Here is the docker-compose file:

version: '3'

services:
  tapo-server:
    image: bluenviron/mediamtx:latest
    container_name: tapo-server
    network_mode: host
    volumes:
      - /home/piyush/tapo:/tapo
      - /home/piyush/tapo/config/mediamtx.yml:/mediamtx.yml
    environment:
      - TZ=Asia/Kolkata
      - PUSH_BULLET_API=XXXX
    restart: unless-stopped

volumes:
  tapo:
    driver: local

mediamtx.yml file:

logLevel: info
logDestinations: [ file ]
logFile: /tapo/logs/cam.log

readTimeout: 10s
writeTimeout: 10s
#writeQueueSize: 8192

rtsp: yes
protocols: [ udp, multicast, tcp ]

record: yes
recordFormat: mpegts
recordPath: /tapo/recordings/%path/%Y-%m-%d_%H-%M-%S-%f
recordSegmentDuration: 5m
recordDeleteAfter: 12h

hlsAlwaysRemux: yes
hlsVariant: fmp4
hlsSegmentCount: 180
hlsSegmentDuration: 10s
hlsPartDuration: 1s
hlsSegmentMaxSize: 50M
hlsDirectory: /tapo/hls/
hlsMuxerCloseAfter: 1800s

metrics: yes


paths:
  cam1:
    source: rtsp://xxx:[email protected]:554/stream1
    sourceProtocol: tcp
    rtspTransport: tcp
  cam2:
    source: rtsp://xxx:[email protected]:554/stream1
    sourceProtocol: tcp
    rtspTransport: tcp

Can anyone help me out how can change the container timezone from UTC to Asia/Kolkata.

Another Question:

Also when I was recording my videos in fmp4 format it is getting recording with 1sec lag. Recorded videos were having 1s lag so I switched to mpegts now the recording is perfect but now I can't use the playback feature. I don't want to install any separate video player.

Is there any way to use the playback for .ts files?

Thanks in advance!

This is resolved. After mapping these additional volumes it is working.
Note: TZ environment has been removed from docker-compose file.

volumes:
   - /etc/timezone:/etc/timezone:ro
   - /etc/localtime:/etc/localtime:ro

Found this solution from this issue:
