DATABASE_URL This connection string is used by PostGraphile. It could be: postgres://postgres:postgres@db:5432/rc4laundry_test.
MIGRATIONS_URL This connection string is used by golang-migrate. It's the same as DATABASE_URL, just with SSL disabled: postgres://postgres:postgres@db:5432/rc4laundry_test?sslmode=false for now.
Export these variables, or place them in a .env file. It must be named .env for docker-compose to detect it automatically.
We also need a .env.db.local file with these three variables, used in the env_file field for the postgres service in docker-compose. It looks something like these.
POSTGRES_USER=postgres
POSTGRES_PASSWORD=postgres
POSTGRES_DB=rc4laundry_test
Once these environment variables are in place, run this.
docker-compose up
