We can bring back this edge case if desired, but it was somewhat unexpected to have localRegistry.enabled = true and it still not be used because of minikube.
This did require using a docker client configured for the minikube environment to work, see later comments.

This update allows the local registry push to work with either the local docker daemon, or the Minikube docker daemon.

This would also miss vcluster + Minikube contexts

Fixed an issue where DevSpace local registry was incorrectly used for virtual clusters on local Kubernetes clusters
What else do we need to know?
Previously the local registry could never be used with minikube. These changes allow the user to opt in to the local registry with Minikube, and makes it consistent with the other local kubernetes options (KinD & Docker Desktop). There isn't a practical reason to do this, but using
localRegistry.enabled=truein the config, and not having the local registry used was unexpected to some during testing.There is also a KinD issue where
--force-buildcreates a new tag, butkind load docker-imagefails to re-tag the image in the KinD cluster, leading to anImagePullBackoff. I've verified this issue exists in DevSpace version before the local registry feature was added. Using the local registry works as a workaround for this issue.
