> booty --help
Easy iPXE server for Flatcar
Usage:
booty [flags]
Flags:
--architecture string Architecture to use for the iPXE server (default "amd64")
--channel string Flatcar channel to look for updates (default "stable")
--dataDir string Directory to store stateful data (default "/data")
--debug Enable debug logging
-h, --help help for booty
--httpPort int Port to use for the HTTP server (default 8080)
--serverIP string IP address that clients can connect to (default "127.0.0.1")
--updateSchedule string Cron schedule to use for cleaning up cache files (default "* */1 * * *")
Features
- PXE boot into the latest Flatcar-Linux
- MAC address based hostnames
- Automatic conversion of Container Linux Config to Ignition JSON
- JSON "Hardware Database" (right now just a MAC-to-hostname mapping)
- Automatic updates retrieved from Flatcar-Linux
- Automatic drain/reboot of nodes (in conjunction with Kured)
Examples
Example ignition config / helper scripts
Docker
docker run --rm -it \
-v $PWD:/data/ \
-p 69:69/udp \
-p 80:8080 \
ghcr.io/jeefy/booty:main \
--dataDir=/storage/ \
--serverIP=192.168.1.10
Kubernetes
This creates a configmap with the example ignition yaml config, a deployment of booty, and a service.
Additional Thoughts
Why?
I like treating (most of) my machines like cattle. This is an easier and more lightweight way to tackle PXE booting and patch management.
Can you make it do X?
