This sounds suspiciously similar to https://github.com/pulumi/pulumi-kubernetes/issues/1731 which was closed back in October. As in the last comment on that thread can you make sure all your pulumi dependencies are up to date and if still having issues raise a new issue at https://github.com/pulumi/pulumi-kubernetes/issues/ referencing the other isuse.

Thanks. I raised it here https://github.com/pulumi/pulumi-kubernetes/issues/1867

Hi facing the same issue. Some even times it would crash with huge traceback that ends on

@victorious-continent-984 can you raise an issue at https://github.com/pulumi/pulumi/issues with more information about that

Sorry, I'm back again. This issue is still not resolved for me. I have updated pulumi and libraries to current releases, but python still hangs. I managed to attach a python debugger to the process and it seems to get stuck forever in

grpc/protobuf

code. I tried stepping through but the stack was 50 deep and just low level serialization code. This is the yaml I'm trying to apply:

<https://github.com/cert-manager/cert-manager/releases/download/v1.8.0/cert-manager.crds.yaml>

If I comment out half of it, it seems fine. If I put some back in, it hangs. But it doesn't seem to matter which bit I comment out, more so the amount. To recap: this used to work on my Intel mac. It works now on a debian arm64 VM running on my m1 mac. It hangs on the mac using python 3.9 arm64 build.

If your still able to repro it might help to add debug logs to the ticket. Run with

--logflow --logtostderr -v9

I've put the log up.

That script will help. I'll have a quick look now.

I've resolved the issue for now. It's not a pulumi root cause, but it certainly is manifested in pulumi. https://github.com/pulumi/pulumi-kubernetes/issues/1867#issuecomment-1107353905
