The Docker team announced support for running Kubernetes using the Docker for Mac application. For a while, it was only available on unstable Edge releases of the Mac application.
Docker for Mac’s Kubernetes cluster is now available in the stable release channel! 🎉
This makes running Kubernetes for local development so much easier. You no longer need to install and run a separate cluster using something like Minikube. (Though, if you need to, I have a guide on installing Minikube on your Mac.)
It's available on Docker Community Edition version
18.06.0-ce-mac70 2018-07-25 or later.
Setting up kubectl to use Docker for Mac is simple.
If you don't already have kubectl installed, the easiest way is with Homebrew.
brew install kubernetes-cli
docker-for-desktop. This will switch kubectl to the
kubectl config current-contextin a Terminal window. It should output
docker-for-desktopif kubectl’s context has updated.
kubectl config viewto output all your available kubectl contexts. (I have a chapter in my book that explains kubectl config in detail)
Once you’ve set up kubectl to use Docker for Mac’s Kubernetes cluster, you can run your first pod!
Create a file called
pod.yaml containing the following YAML configuration.
Now run the pod, and then check its status as it gets run on Docker for Mac’s single node cluster
$ kubectl create -f pod.yaml pod "example-pod" created $ kubectl get pods NAME READY STATUS RESTARTS AGE example-pod 1/1 Running 0 2m
I’d expect Minikube to stick around for a while—it’s a much more stable and mature implementation of a single-node Kubernetes cluster that you can run locally on your Mac. But Docker for Mac is a great, simple way to run a simple cluster on your local machine. Plus, the Docker menu bar icon gives you a new, fast way to switch kubectl contexts.
