Hello,

We find the operator builder really useful, although I have issues running the ref implementation.

FYI - I am running this on WSL2
cat /etc/release

FATA[0004] failed to create API: unable to run post-scaffold tasks of "base.go.kubebuilder.io/v3": exit status 2

Any ideas why this might be?

@lander2k2 @scottd018. I'm able to reproduce this error on v0.6.0. Can you take a look at what might be missing from the readme?

[scottd018]

@ahuffman was able to produce with go1.18.3 (works with 1.17.9). @lander2k2 and I already had 1.18 on the roadmap, but we aren't quite there yet. let me see if i can find a quick workaround for you in the meantime

[scottd018]

@ahuffman @martonadam47 You can try this again using the latest update in main branch of operator-builder (simply clone and use make build to create a binary artifact from the cloned repo at bin/operator-builder). We went ahead and updated to Go version 1.18 across most projects in the stack and I was able to get this issue fixed by doing so.

See issue nukleros/operator-builder#39 for more info.

Also note that operator-builder moved to a new location at https://github.com/nukleros/operator-builder . Let me know if you have issues! :)

[ahuffman]

@martonadam47 I validated this is fixed with the current code in https://github.com/nukleros/operator-builder. I also went ahead and updated the docs.

Thanks for reporting this to us!
