Assigned ports
The following is a non-exhaustive list of ports used by Sentry services or any dependency of a Sentry service in development setups. It serves two purposes:
- Finding out why a port is used on your work machine and which process to kill to make it free.
- Finding out which ports are probably safe to assign to new services.
| Port | Service | Description |
|---|---|---|
| 9000 | Clickhouse | Devservice clickhouse. Database for Snuba. |
| 8123 | Clickhouse | |
| 9009 | Clickhouse | |
| 3021 | Symbolicator | Devservice symbolicator. For processing stacktraces. |
| 1218 | Snuba | Devservice snuba. For searching events. |
| 1219 | Snuba admin | Not part of devservices setup, but running snuba admin will listen on this port. |
| 9092 | Kafka | Devservice kafka. for relay-sentry communication and optionally for sentry-snuba communication |
| 6379 | Redis | Devservice redis (or perhaps installed via Homebrew in rustier setups), responsible for caches, relay projectconfigs and Celery queues |
| 5432 | Postgres | Devservice postgres (or perhaps installed via Homebrew in rustier setups) |
| 7899 | Relay | Devservice relay. Serves APIs for SDKs to send events to (aka event ingestion). Webpack on 8000 reverse-proxies to this server. Starts/stops with sentry devserver. |
| 8000 | Sentry Dev | Webpack devserver, routing all ingest paths to Relay, and the rest to uWSGI. Routing is defined in webpack.config.ts in Sentry. |
| 8001 | uWSGI | Starts/stops with sentry devserver. Serves the Django app/API. Webpack on 8000 reverse-proxies to this server. In a siloed devserver, this port is used for control silo. |
| 8010 | uWSGI (region silo) | Starts/stops with sentry devserver --silo=region. Serves the Django app/API. Webpack on 8000 reverse-proxies to this server. |
| 7999 | Sentry frontend prod proxy | For testing local UI changes against a prod API |
| 8000 | Develop docs | The website around this document. Conflicts with Sentry Dev. |
| 3000 | User docs | User-facing documentation. May conflict with Relay if Relay is run outside of devservices. |
| 9001 | Sentry Dev Styleguide server | Bound when running sentry devserver --styleguide |
| 9000 | sentry run web | Legacy default port for sentry run web, changed to 9001 to avoid conflict with Clickhouse. |
| 9001 | sentry run web | Barebones frontend without webpack or Relay. Sentry Dev is likely better. Conflicts with Sentry Dev Styleguide server. |
| 8000 | Relay mkdocs documentation | At some point this is going to get merged into our existing docs repos. Conflicts with Sentry Dev. |
Finding out what's running on your machine
- Use
lsof -nP -i4 | grep LISTENto find occupied ports on macOS. - The Dashboard UI of Docker for Mac shows you running docker containers/devservices together with assigned ports and option to start/stop.
