## Features
- includes bitnami subcharts for [valkey](https://github.com/bitnami/charts/blob/main/bitnami/valkey/README.md#parameters) (redis) and [postgresql](https://github.com/bitnami/charts/blob/main/bitnami/postgresql/README.md#parameters) (database)
- but you can also bring your own valkey, redis, or postgresql database
- helm parameter docs autogenerated via helm-docs
- use existing Secrets for valkey, postgresql, and smtp
- RenovateBot keeps the subcharts and docker image up to date
- configurable liveness and readiness probes
