​
Docker environment variables

docker-compose.yml sets reasonable defaults for local development. For anything public-facing, change secrets and run behind HTTPS.

​
Required

  • DATABASE_URL: Postgres connection string. With Docker Compose, Postgres is published on localhost:5433 by default.
  • BETTER_AUTH_SECRET: Secret used to sign auth/session data. Change this.
  • BETTER_AUTH_URL: Public URL of the app (e.g. http://localhost:3000).
  • NEXT_PUBLIC_APP_URL: Public URL of the app (same as above for most setups).

​
Optional (Telegram approvals)

If you want Telegram notifications/approvals, you’ll also need Telegram-related env vars and a webhook (see Telegram integration).

​
CLI configuration

The CLI stores defaults in ~/.latch/config.json. See CLI.
