Kubernetes image for Mono Gateway Development Kit
|
|
|
|
https://docs.mono.si/gateway-development-kit/getting-started
|
|
|
|
## DISCLAIMER
|
|
USE AT YOUR OWN RISKS. I leverage ChatGPT heavily for this. I am testing them all by myself right now.
|
|
|
|
### The device's dts files are located at here
|
|
https://github.com/we-are-mono/OpenWRT-ASK/tree/mono-25.12.0-rc3/target/linux/layerscape/files/arch/arm64/boot/dts/freescale
|
|
* We need both `mono-gateway-dk-sdk.dts` and `mono-gateway-dk.dts` since the sdk one includes the non-sdk one.
|
|
* The actual dts being used is the `mono-gateway-dk-sdk.dts`
|
|
|
|
## Build
|
|
|
|
Find the latest package versions and update build.env
|
|
* [kernel](https://github.com/nxp-qoriq/linux/archive/refs/tags/)
|
|
* [busybox](https://github.com/mirror/busybox/archive/refs/tags/)
|
|
* [CRI-O](https://github.com/cri-o/cri-o/releases)
|
|
* [Kubelet](https://kubernetes.io/releases/download/)
|
|
|
|
Then run
|
|
```
|
|
make release
|
|
```
|
|
|
|
### Making sub stages
|
|
```bash
|
|
make build-base # The image the builds kernel and everything
|
|
make kernel # Builds our kernel from NXP
|
|
make initramfs
|
|
make itb # Builds out/board.itb (contains the kernel and the initramfs)
|
|
```
|
|
|
|
## Architecture
|
|
- A/B deployment
|
|
- Read-only OS
|
|
|
|
## Upgrade process
|
|
Rough idea
|
|
|
|
```bash
|
|
./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
|
|
|
|
```
|
|
|
|
```yaml
|
|
PENDING
|
|
```
|
|
|
|
## tftp (network is required)
|
|
```
|
|
setenv ipaddr 10.0.0.153
|
|
setenv serverip 10.0.0.129
|
|
tftp 0x80000000 board.itb
|
|
```
|
|
|
|
## USB Flashing
|
|
1. Copy board.itb into an SDCard
|
|
2. Copy `[RELEASE_NAME].img.gz` into an SDCard
|
|
```
|
|
usb start
|
|
usb tree
|
|
fatls usb 0:1 # For fat
|
|
ext4ls usb 0:1 # For ext4
|
|
fatload usb 0 0x80000000 board.itb
|
|
|
|
setenv bootargs "console=ttyS0,115200 earlycon=uart8250,mmio,0x21c0500 root=/dev/ram0 rootwait rw"
|
|
bootm 0x80000000
|
|
```
|
|
|
|
3. Inside initramfs
|
|
```
|
|
mount /dev/sda /mnt
|
|
gunzip -c /mnt/[RELEASE_IMAGE].img.gz | dd of=/dev/mmcblk0
|
|
reboot -f
|
|
```
|
|
|
|
4. If it boots, create the A/B deployment scheme
