Kubernetes image for Mono Gateway Development Kit
|
|
|
|
https://docs.mono.si/gateway-development-kit/getting-started
|
|
|
|
### 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
|
|
|
|
To avoid frequent downloading on rebuild. Find and download the latest packages
|
|
* [kernel](https://github.com/nxp-qoriq/linux/archive/refs/tags/) - `dev/nxplinux.tar.gz`
|
|
* [busybox](https://github.com/mirror/busybox/archive/refs/tags/) (for initramfs) - `dev/busybox.tar.gz`
|
|
* [CRI-O](https://github.com/cri-o/cri-o/releases) - `dev/crio.tar.gz`
|
|
* [Kubelet](https://kubernetes.io/releases/download/) - `dev/kubelet.tar.gz`
|
|
|
|
Put them into the `dev/` directory
|
|
|
|
```bash
|
|
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
|
|
|
|
```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
|
|
```
|
|
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
|
|
```
