Environment Variables and Settings
Environment Variables
As many other applications, Dawarich uses environment variables to configure its behavior. The following environment variables are supported:
| Environment Variable | Default Value | Description |
|---|---|---|
RAILS_ENV | development | Application environment. development value makes sure all errors will be shown explicitly, making easier remote debugging |
REDIS_URL | redis://dawarich_redis:6379/0 | Redis URL |
DATABASE_HOST | dawarich_db | Database host |
DATABASE_USERNAME | postgres | Database username |
DATABASE_PASSWORD | password | Database password |
DATABASE_NAME | dawarich_development | Database name |
MIN_MINUTES_SPENT_IN_CITY | 60 | Minimum minutes spent in a city |
APPLICATION_HOSTS | localhost,my.domain.com | Application hosts, provide multiple if you want your Dawarich instance to be available by multiple domains/ip addresses. Don't put protocols here, only host names. |
APPLICATION_PROTOCOL | http | Application protocol. Change to https if you want your Dawarich instance to be served via SSL |
TIME_ZONE | Europe/London | Time zone. Full list of supported timezones available on Github |
DISTANCE_UNIT | km | Distance unit. For miles, change to mi. All settings still should be provided in meters/kilometers |
RAILS_MAX_THREADS | 5 | Connection pool size for the Dawarich database |
BACKGROUND_PROCESSING_CONCURRENCY | 10 | Background processing concurrency. Should not be higher than RAILS_MAX_THREADS. More info on Sidekiq docs |
PROMETHEUS_EXPORTER_ENABLED | false | Prometheus exporter enabled |
PROMETHEUS_EXPORTER_HOST | 0.0.0.0 | Prometheus exporter host |
PROMETHEUS_EXPORTER_PORT | 9394 | Prometheus exporter port |
DISABLE_TELEMETRY | false | Disable telemetry |
PHOTON_API_USE_HTTPS | nil | Use HTTPS for Photon API requests |
PHOTON_API_HOST | nil | Photon API host. Useful if you're self-hosting your own Photon instance |
PHOTON_API_KEY | nil | Photon API key. Useful if you're supporting Dawarich development on Patreon and want to use Photon API instance hosted by Freika without any limits |
GEOAPIFY_API_KEY | nil | Geoapify API key. Provide your own key if you want to use Geoapify reverse geocoding service |
Important note on Prometheus exporter: even if you want to use it, make sure you have PROMETHEUS_EXPORTER_ENABLED set to false in dawarich_sidekiq container. Otherwise, you'll end up with two exporters and will have to deal with duplicate metrics. The PROMETHEUS_EXPORTER_HOST for dawarich_sidekiq should be set to dawarich_app or your name of the container.
