issue while signing (sigstore-keycloak-setup)

[VikramPunnam]

Hi @mayaCostantini , the guide which you wrote is very helpful for local sigstore setup.

I have configured the keycloak and fulcio as mentioned, but Im getting the below error.

main.go:74: error during command execution: signing [qa-harbor.crisil.local/eks/alpine:1.27.4]: getting signer: getting key from Fulcio: retrieving cert: oauth2: "invalid_grant" "Code not valid"

If you have any idea,

Could you please help on this?

Hi @VikramPunnam, thanks! Could you please provide the command you ran and a full stack trace of the error?

[mayaCostantini]

I think this might either be an issue with your Keycloak realm/client config or with the verification code itself (it might have already been used or timed out). Could you also provide your Keycloak config?

[VikramPunnam]

yes,

The issue is with the keycloak config. The client token is valid only once.

I have tried with new client token. but getting different issue.

[mayaCostantini]

Error entering certificate in CTL could be caused by different issues with Fulcio's CTL, you might want to check the CTL server logs directly, a more precise stack trace should be visible there.
