Turns out the problem is what I described here. So it isn't a problem with this image, I'll close this issue.

[TheKevJames]

Hmm, I believe we've got a few folks at $company which are on M1s who have this working, so I'm not sure that'd be it. I don't believe I've heard of this being used in minikube yet -- though I can't really see how that'd affect things.

If you could narrow down the issue, that'd be helpful: does it work for you on the same machine outside of minikube? What if you play with Rosetta emulation settings? etc.

I'd also be curious if 406.0.0 works for you -- that was the last build using a quite different base image, which might help narrow down the issues.

Hi @TheKevJames , first of all, thank you for the project! 👏

Sorry if I'm jumping in with information that is not completely related, but the messages are quite similar, so I figured they might help narrowing down issues. When I run gcloud-pubsub-emulator on 453.0.0 I also hit a very similar message, but not on 452.0.1:

$ docker run --rm -it -p 8681:8681 thekevjames/gcloud-pubsub-emulator:453.0.0

Coincidence or not, I'm also using a Mac M1, no Rosetta, and the installed Java - via sdkman - is:

$ java --version
openjdk 17.0.4.1 2022-08-12
OpenJDK Runtime Environment Temurin-17.0.4.1+1 (build 17.0.4.1+1)

I hope any of this information can be helpful. Personally I've been using the fixed version, so nothing is impacted directly. Let me know if I can help with anything, like opening a dedicated issue, trying to pin down more details, or run any other tests.

[TheKevJames]

I've just switched the base image back to non-slim as it seems it might have exasperated this issue / caused a related issue / etc as you've described. /cc @lacarvalho91 @tomaytotomato FYI. v453.0.0 will get updated with the non-slim build shortly.

@moret thank you for the additional information! It looks like one thing I can glean from that is that an M1 mac which is configured to run the linux/amd64 image this is based on works just fine. @lacarvalho91 do you get the same emulation warning as moret? eg. WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested ? If not, I'm thinking the emulation side of things would indeed be the issue here.

Sounds like this might be about the time to start looking into multi-architecture builds for this image, we might need a arm64-native build to support some of these use-cases.

[lacarvalho91]

@TheKevJames I get that message when i run it normally locally, but not when I run it in minikube locally. Outside of minikube it seems to work fine, looks like its only in minikube that I see this Java error.

I just tried with both 452.0.1 and 453.0.0, neither seem to work in minikube from my local machine (they do from minikube on our CI server I believe, will double check)

Strange one,

Are you using a Mac M1/M2 as your local dev machine?

[lacarvalho91]

I am yeah, M1. When I run the image from my machine outside of minikube I get the warning message and then it works fine. When I run the image from my machine but inside minikube I don't get the warning but then it doesn't work as I get this Java error message.

[lacarvalho91]

The minikube release I'm using is for ARM so I was expecting to see the WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested message in minikube too but I don't 🤔 wonder if thats the problem? Its not trying to do the emulation when it probably should be?

[lacarvalho91]

It seems to work for my colleague who is running the same minikube task but is not on an M1.
