Fluxcd sign its commits

Question

I want to config Flux to sign its commit on the repository. I passed gpg key in bootstrap command but it just signs the first commit that it does for creating flux-system directory, but for example when I have a new tag in my image repository, Flux will change the image tag in my manifest in my repo and commit it and then apply in my Kubernetes cluster, now I want to sign this kind of commits as well.

Answer 1

Add the following part in ImageUpdateAutomation manifest:

      signingKey:
        secretRef:
          name: flux-key

Image update controller will sign the commits.
