How to build a Docker image from source code now? #735

I noticed that in the latest version of the project, the docker-build target has been removed from the Makefile. Previously, I used this target to build the source code into a Docker image. Is there an alternative way to build the project as a Docker image now? I have changed some code and now want to test.

Are there new recommended commands or scripts for this process? Any guidance would be appreciated.

With #560 we migrated to ko which provides OCI artifacts.

By default, make build will generate a ko build for OCI, such as container images. By default, the KO_LOCAL variable is set to false, meaning you can use Skopeo or kind load docker-image.

If you want to push to your container registry, you can run something as:

make CONTAINER_REPOSITORY=your.container.registry.tld KO_PUSH=true build

Result will be something as:

LD_FLAGS="-X github.com/clastix/kamaji/internal.GitCommit=$(git rev-parse --short HEAD) -X github.com/clastix/kamaji/internal.GitTag=edge-25.03.1 -X github.com/clastix/kamaji/internal.GitDirty=$(echo "$(git diff $(git rev-parse --short HEAD) $(git rev-parse --short edge-25.…
