Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
We need a way to update the dependencies mentioned inside the Dockerfile definition. Dependabot does not support this but Renovate does, allowing to treat arbitrary strings as version identifiers. This also includes support for updating the kubectl, kustomize, and helm versions included in the Dockerfile.
