Dependencies

This page describes the external services and tooling needed to run Tempo Watchtower in development or production.

PostgreSQL

PostgreSQL stores transactions, scheduler state, and metadata. You must create a database for Tempo Watchtower and provide the credentials when configuring.

Redis

Redis is used to improve scheduling performance. The database remains the source of truth; Redis can be rebuilt from Postgres.

Reverse Proxy (optional)

A reverse proxy is recommended when exposing the service to the Internet. It can terminate TLS, apply rate limits, and manage access controls in front of the Watchtower API. We provide a sample configuration for nginx as part of this repo.

Supervisor (optional)

A process supervisor is recommended for production deployments to keep the service running and to manage restarts on failure. We provide a sample configuration for supervisor as part of this repo.
