Yes, you need to build the image for the architecture you are running on. You can use

docker buildx build --platform=linux/amd64 <rest of build command>

to "cross compile"

I'm not sure also about "local image". Is it published to the docker hub, or any other public registry? Or was it just built locally?

Thanks for fast reply. Usually I use Epinio for building and deploying. Just want to try if I can use my local image. However, that is the command that I always use to build my image. So, it not working as I said. local image is just built locally, Do I need to run my own registry ? I’m really new to this. English is not my primary language, sorry about that.

yes, so probably that's the issue. The image is fetched from an external registry (your local is not visible to the kubelet). So you could either push it to the docker hub, run your own registry (and deploy epinio with this settings), or maybe copy your image to the registry that epinio already deployed internally in your cluster

There is some weirdness with buildx and usage of the built images 😞 I don't fully understand why this is the case but the easiest option would be to push to docker hub. To make this a little less frustrating, you can use the flag

--push

in the buildx command. Here's an example from my bash history:

docker buildx build --platform=linux/amd64 --push ./ -t atgracey/game-ui-server-onsite:stable

I think the easiest way is just push it to Dockerhub. I’ll try again tomorrow. Thank you both of you !

Of course! Let us know if anything doesn't work. It might be worth adding a note into our docs about this weirdness with buildx
