Configuring a Kubernetes Cluster

So I am having another look at Kubernetes.  I used it a few years ago but switched to using Docker Swarm.  I like Docker Swarm;  I like the simplicity, I like the familiarity.  But the industry is predominantly using Kubernetes, and a lot has changed since I last used it.  I am going to document here how I go about re-familiarising myself with Kubernetes.

I am using an Apple MacBook Pro todo the majority of the work and as my development machine.  It is quite easy to get Kubernetes running on a Mac by installing minikube and kubectl. Ensure that Docker is installed. I installed it from the Docker web site here. This is very simple with Homebrew. Just run the following commands:

brew install kubectl
brew cask install minikube

You will also need to install a virtualisation technology to use this. VirtualBox is probably the easiest to install. Follow instructions on their site here. Once everything was installed, I validated that all is installed fine with the following commands:

kubectl version --output=yaml
minikube version

Then, to start a local Kubernetes cluster, run the following command:

minikube start --vm-driver=virtualbox

running minikube status responds with:

minikube: Running
cluster: Running
kubectl: Correctly Configured: pointing to minikube-vm at 192.168.99.100

From this, I know that everything is up and running as expected.

I can now launch the dashboard using minikube dashboard. This will launch the dashboard in your default browser.
