Special notes for your reviewer:

[Kalaiselvi84]

The make cloud-build command has succeeded for all the necessary example images(autoscaler-webhook, crd-client, supertuxkart, xonotic, and simple-game-server) in my project. The files go.mod and go.sum have been updated only for the autoscaler-webhook image.

Please confirm if this looks good to you to push these new images to production. I will commit the remaining file updates in this PR after the push.

LGTM! @igooch you got anything?

[igooch]

We should update the mod files as well for the main repo and the examples ~/agones$ go mod edit -go=1.21. You might need to update your machine and IDE Go versions to 1.21 in order to run go mod tidy after the change to 1.21 in the go.mod files.

Good call 👍🏻

[Kalaiselvi84]

Installed the Go v1.21.6. and updated the mod files using go mod edit -go=1.21 and go mod tidy.

We should update for the go.mod files in the examples/ directories as well.

We should update for the go.mod files in the examples/ directories as well.

I used the same commands but mod files haven't modified. Am I missing anything?

~/Desktop/agones/examples$ go mod edit -go=1.21
~/Desktop/agones/examples$ go mod tidy

Following commands help to update the subdirectories of mod and sum files:

agones/examples$ find . -name 'go.mod' -execdir go mod edit -go=1.21 ;
agones/examples$ find . -name 'go.mod' -execdir go mod tidy ;

Test failure will likely be fixed with #3603.

This LGTM. @igooch anything else on your end?
