Database configuration

There are multiple ways of configuring the database connection used by Gaia, depending one how Gaia is started.

source & docker-compose

When starting Gaia using source code and docker-compose, a MongoDb database is created alongside Gaia, and Gaia is configured directly to use it:

version: "3"
services:
  gaia:
    build: .
    image: gaia
    ports:
      - '8080:8080'
    environment:
      - "GAIA_MONGODB_URI=mongodb://mongo/gaia"
      - "GAIA_EXTERNAL_URL=http://172.17.0.1:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

  mongo:
    build:
      context: .
      dockerfile: ./Dockerfile-db
    image: gaia-db

To use a different MongoDb instance, replace the GAIA_MONGODB_URI environment variable with the URI of your database, and remove the provided MongoDb instance. If your database uses user/password authentication, pass them in the URL as well :

version: "3"
services:
  gaia:
    build: .
    image: gaia
    ports:
      - '8080:8080'
    environment:
      - "GAIA_MONGODB_URI=mongodb+srv://gaia:gaia_database_password@gaia-gcp-europe-west1-azerty.gcp.mongodb.net/gaia?retryWrites=true&w=majority"
      - "GAIA_EXTERNAL_URL=http://172.17.0.1:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

docker

When starting Gaia using docker, use environment variables to setup MongoDb URI :

docker run -d \
  --name gaia-server \
  -e GAIA_MONGODB_URI=mongodb+srv://gaia:gaia_database_password@gaia-gcp-europe-west1-azerty.gcp.mongodb.net/gaia?retryWrites=true&w=majority \
  gaia-app/gaia

jar

When starting Gaia using the jar, you can change the MongoDb URI using JVM parameters :

java -jar gaia.jar -Dgaia.mongodb.uri=mongodb+srv://gaia:gaia_database_password@gaia-gcp-europe-west1-azerty.gcp.mongodb.net/gaia?retryWrites=true&w=majority
