docker compose

Overview

Docker Compose uses environment variables to customize container configurations. These variables can be defined in multiple ways to support different deployment scenarios.

Env file

The .env file is a key-value file placed in the same directory as your docker-compose.yaml. It contains environment variables that will be loaded by Docker Compose.

Example .env file:

https://github.com/atomic-blend/backend/blob/main/.env.example

ENV=dev
DATABASE_NAME=atomic-blend
TASK_APP_URL=http://localhost:80

# define external DB
# MONGODB_URI=
## generate using "openssl rand 256 | base64 -w0"
SSO_SECRET=secret
GOOGLE_APPLICATION_CREDENTIALS=
FIREBASE_PROJECT_ID=
RESEND_API_KEY=
