Kubernetes image for Mono Gateway Development Kit
https://docs.mono.si/gateway-development-kit/getting-started
DISCLAIMER
I used ChatGPT a lot for this. I also tested them thoroughly enough that until confident that's what we need.
The device's dts files are located at here
- We need both
mono-gateway-dk-sdk.dtsandmono-gateway-dk.dtssince the sdk one includes the non-sdk one. - The actual dts being used is the
mono-gateway-dk-sdk.dts
Build
To avoid frequent downloading on rebuild. Find the latest packages and update build.env
Then run
make download-packages
make itb # for out/board.itb (contains the kernel and the initramfs)
make release # WORK IN PROGRESS
Architecture
- A/B deployment
- Read-only OS
Upgrade process
Rough idea
./configure
# - asks for some config for kubelet
# - Join a cluster? Start a cluster?
make release
# Copy the new image to the upgrade-scheduler
kubectl cp -n kube-system upgrade-scheduler:/tmp/upgrade.img
# Upgrade scheduler reads the file that issue a self-reboot
reboot
# uboot to boot into partition B
