# SignalHaven example docker compose stack.
#
# Copy `.env.example` to `.env` (and edit the credentials) before running:
#
#   docker compose up -d
#
# The `signalhaven` service waits for `postgres` to become healthy before starting
# and then connects to it via SIGNALHAVEN_DATABASE_URL. To point SignalHaven at an
# external Postgres instead, remove the `postgres` service and `depends_on`
# block below and set SIGNALHAVEN_DATABASE_URL in your `.env` to the external
# connection string.
