# Configuration Opengist provides flexible configuration options through either a YAML file and/or environment variables. You would only need to specify the configuration options you want to change — for any config option left untouched, Opengist will simply apply the default values. The [configuration cheat sheet](cheat-sheet.md) lists all available configuration options. ## Configuration via YAML file The configuration file must be specified when launching the application, using the `--config` flag followed by the path to your YAML file. Usage with Docker Compose : ```yml services: opengist: # ... volumes: # ... - "/path/to/config.yml:/config.yml" ``` Usage via command line : ```shell ./opengist --config /path/to/config.yml ``` You can start by copying and/or modifying the provided [config.yml](https://github.com/thomiceli/opengist/blob/stable/config.yml) file. ## Configuration via Environment Variables Usage with Docker Compose : ```yml services: opengist: # ... environment: OG_LOG_LEVEL: "info" # etc. ``` Usage via command line : ```shell OG_LOG_LEVEL=info ./opengist ```
