Deployment

Default configuration is defined in config/default.toml. SwissKnife supports .toml, yaml and json config files. The order of applied configuration is the following:

1. ENV vars. Defined given the names of the config values in default.toml, adding the prefix SWISSKNIFE. Overriding all sensitive values with ENV vars is recommended.
2. any file under config corresponding to the RUN_MODE (development by default). Such as development.toml|yaml|json or `production.toml|yaml|json``
3. The default.toml|yaml|json file.

Inspect the .env.example file for and generate your own .env for sensitive config values.
