Thanks, just more details: I also tried the exercise on a Ubuntu VM via Parallels and got the same results. So, hoping multi-arch images will do the trick.

I prepared a three node Raspberry Pi cluster to begin learning K8s. Unfortunately, I have been having trouble making progress with KIAMOL. It was not until I looked at the container definitions and manually tried running them in Docker that I realized that ARM V7 was not supported. I really hope that this can be sorted out soon.

I've been building my own images along the way and pushing to my docker.io account, as we have the definition for most of the images -- I'm still looking for a few - I'm using ARM64 so your mileage may vary.

Fundamentally:

build images you want
tag for your account
add manifest
push manifest
change deployment file from kiamol/image to /image
(I used "diamol" to learn how to do some of this.)

e.g. ch11 bulletin board. cd to ch11/bulletin-board
docker build -t kiamol/ch11-bulletin-board:linux-arm64 --platform linux/arm64 -f docker/Dockerfile .
docker build -t kiamol/ch11-bulletin-board:linux-amd64 --platform linux/amd64 -f docker/Dockerfile .
docker build -t kiamol/ch11-bulletin-board:linux-arm --platform linux/arm -f docker/Dockerfile .

docker image tag kiamol/ch11-bulletin-board:linux-arm64 jurlwin/ch11-bulletin-board:linux-arm64
docker image tag kiamol/ch11-bulletin-board:linux-amd64 jurlwin/ch11-bulletin-board:linux-amd64
docker image tag kiamol/ch11-bulletin-board:linux-arm jurlwin/ch11-bulletin-board:linux-arm

docker manifest create "jurlwin/ch11-bulletin-board" "jurlwin/ch11-bulletin-board:linux-amd64" "jurlwin/ch11-bulletin-board:linux-arm64" "jurlwin/ch11-bulletin-board:linux-arm"
docker manifest push "jurlwin/ch11-bulletin-board"

You are welcome to pull mine, but I'm not paying attention as I go and I may have good or bad results for you.

But I'm also still in progress.. :)

Good luck
