I remember a similar PR in NMO, where Marc also updated the Dockerfile to ensure the go version was the same as defined in go.mod.
Do you think we need it here as well?

I can add the Dockerfile change. Do you want me to add the CI build_root_image as well?

I don't know what is the effect of that file 😅

IIUC the .ci-operator.yaml file was used in NHC to replace the build image , so that Marc doesn't need to modify the base image in CI. He could simply do it from NHC github repo.

Usually we use Golang base image as build images and we modify it in CI, after we have changed our code Golang version. By using the .ci-operator.yaml file we can update Golang version in CI from NHC github repo without worrying about CI.

FYI MDR already use this file - https://github.com/medik8s/machine-deletion-remediation/blob/main/.ci-operator.yaml
