# puu-installer

Standalone installer for bootc-based OSs.

## Configuration

The installer reads a YAML configuration file. Its path is taken from
`--config`, or from the `PUU_INSTALLER_CONFIG` environment variable when
`--config` is not given. `--config` takes precedence over the environment
variable.

The k3s cluster token is the only k3s setting passed on the command line, via
`--k3s-token-file` (the file's first line is used). All other k3s settings live
in the configuration file.

All keys are optional; the values below are the defaults.
