ARM64 image for Krew plugin

[benkelukas]

Hello,

I'm trying to use the tunnel krew plugin on Mac M1 to tunnel to a local Kube cluster (Docker for Mac)

It seems that there is not a published version for arm64 on quay.io, and if I try to use the amd64 through rosetta, it segfaults and does not create the tunnel:

Output from running the docker container directly:

docker run --rm quay.io/omrikiei/ktunnel:v1.4.8
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
qemu: uncaught target signal 11 (Segmentation fault) - core dumped

Output from running the Krew plugin:

Would it be possible to publish the arm64 image?

Thanks for the awesome work on this tool!

I'll try to get this fixed over the weekend, sorry for the inconvenience, in the meanwhile it's possible to build a supported image and pass the --image flag to the CLI

[benkelukas]

@omrikiei no worries, thanks for looking into this! :)

[igoooor]

@benkelukas have you been able to build an image working for ARM64? For me it says upx (no such package)

[igoooor]

or maybe @omrikiei you may have had time to already look into it? Sorry for bothering you I know it's been only ~20 days since your last comment

[omrikiei]

@igoooor not yet, what I can say is that upx is only used to compress the binary, it is not required for pure functionality - feel free to remote this line from the Dockerfile

[igoooor]

Nice it seems to work indeed, thank you very much for the explanation!
