Environment Variables

Most of our containers are configured primarily via environment variables. They follow upstream conventions — refer to each application’s per-container page for the supported keys.

Setting Variables

Docker Compose

services:
  my-app:
    image: ghcr.io/trueforge-org/my-app:latest
    environment:
      TZ: Europe/Amsterdam
      LOG_LEVEL: info

Podman / Docker CLI

docker run -e TZ=Europe/Amsterdam -e LOG_LEVEL=info ghcr.io/trueforge-org/my-app:latest

Kubernetes

env:
  - name: TZ
    value: Europe/Amsterdam
  - name: LOG_LEVEL
    value: info

Loading From a File

For long lists of variables, use an env file:

services:
  my-app:
    image: ghcr.io/trueforge-org/my-app:latest
    env_file:
      - ./my-app.env

Time Zone

All our images respect the standard TZ variable, e.g. TZ=Europe/Amsterdam. If unset, the container defaults to UTC.
