Using Environment Variables

Database connection

If your database credentials are in the environment then you should configure something like the following. If it's in one variable as an URL then use the url key, e.g., mysql://USER:PASSWORD@HOST:PORT/DB_NAME.

local:
  database:
    backups: private/default/db/purgeable
    uri: $DATABASE_URL

If you need to point to an environment file to be automatically loaded first you can add this

local:
  env_file:
    - .env
