The demo app image (json-mock) point to wrong architecture

[hazelnutsgz]

What happened?

I am trying to deploy the application demo on arm64 VM following the official page https://tetragon.io/docs/getting-started/install-k8s/#deploy-demo-application, the xwing andtiefighter pod can not start successfully.

The log of the 2 pods are:

standard_init_linux.go:228: exec user process caused: exec format error

I tried to download the image json-mock behind these two pods, it can work.

I think one way to solve it is specify the ARCH in https://raw.githubusercontent.com/cilium/cilium/v1.15.0-pre.1/examples/minikube/http-sw-app.yaml

Thanks for the report!

I haven't looked into this but I guess the images used here are not multi-arch and might only run on x86. The next step would be to look into the images used here and see if we can make them multi-arch.

I think it was fixed by those two PRs:

• https://github.com/cilium/cilium/pull/31373
• https://github.com/cilium/tetragon/pull/2311

Feel free to reopen if it's not the case.
