## Documentation

# Deploy and Host Patroni on Railway

Patroni is a template for high availability (HA) PostgreSQL solutions using Python. Database engineers, DBAs, DevOps engineers, and SREs who are looking to quickly deploy HA PostgreSQL in datacenters - or anywhere else - will hopefully find it useful.

## Common Use Cases

- Extremely high availability hosted Postgres.
- Postgres that never, ever goes down.

## HAProxy Configuration
When you deploy HAProxy, a password will be generated under the variable `STATS_PASSWORD`. You can use this with the username `admin` to log into the statistics page at the service's public domain.

HAProxy template configuration: https://github.com/thesamgordon/patroni-haproxy/blob/main/haproxy.template.cfg
