# Configuration

Cedana configuration lives in `/etc/cedana/config.json`. You can initialize this file with default values by using the `--init-config` flag (e.g. `sudo cedana daemon start --init-config`). Any configuration in environment variables will override the default values when this file is initialized. You may also merge currently set environment variables into an existing configuration file with the `--merge-config` flag (e.g. `sudo cedana daemon start --merge-config`).

## Environment variables

You may also override the configuration file using environment variables. The environment variables are prefixed with `CEDANA_` and are in uppercase. For example, `Checkpoint.Dir` can be set with `CEDANA_CHECKPOINT_DIR`. Similarly, `Connection.URL` can be set with `CEDANA_CONNECTION_URL`, or its alias `CEDANA_URL`.

Each of the below fields can also be set through an environment variable with the same name, prefixed, and in uppercase. E.g. `Checkpoint.Dir` can be set with `CEDANA_CHECKPOINT_DIR`. The `env_aliases` tag below specifies alternative (alias) environment variable names (comma-separated).
