In development, docker handles all db services for us. This is done by calling docker-compose on the Compose file ./docker/dev.yml. The web app itself is not containerized; it simply runs on the host machine by calling yarn && yarn dev
In production, dokku creates a Docker container using the default Node.js heroku buildpack. While it's possible to do so, we don't yet provide any custom Dockerfile to dokku.
Self-hosted instances may use the docker-compose.yml file in the root of the project directory. All services, including databases and the web app, will be containerized.
If the owner of the self-hosted instance wants to use local file storage (instead of cloud storage such as AWS or GCP) for user uploaded images, make sure FILE_STORE_PROVIDER='local' in the root .env file. Additionally, the app must be deployed using the following command:
docker-compose -f docker-compose.yml -f ./docker/docker-compose.selfHosted.yml up -d
This ensures that the images will be persisted in a Docker volume.
