Quick notes on the installaton of Minikube for trying out Kubernetes on my Windows 10 laptop (using VirtualBox –not Hyper-V)
Following instructions in https://www.ibm.com/support/knowledgecenter/en/SS5PWC/minikube.html
Download Windows installer for MiniKube:
After running the installer, open a command line window
curl -o kubectl.exe https://storage.googleapis.com/kubernetes-release/release/v1.8.0/bin/windows/amd64/kubectl.exe
Copy downloaded file to a proper location – of your choosing – and add that location to the PATH environment variable.
Open a new command line window, set MINIKUBE_HOME
to start Minikube.
The VM image is downloaded in which the Kubernetes cluster will be created and ran. This image is 139 MB, so this startup takes a while – but of course only the first time.
The directory .minikube is created:
And in VirtualBox you will find a new VM set up and running:
and the browser will open:
with an overview from within the VM of the Kubernetes Cluster.
you can halt the cluster – later to be started again using minikube start
A restart now only takes 10-15 seconds:
Using the instructions here – https://github.com/kubernetes/kubernetes/blob/master/examples/simple-nginx.md – I can quickly run a Docker Image on my minikube cluster:
kubectl run my-nginx –image=nginx –port=80
This will create two nginx pods listening on port 80. It will also create a deployment named my-nginx to ensure that there are always two pods running.
In the dashboard, this same information is available:
kubectl expose deployment my-nginx –type=”NodePort”
is used to expose the deployment – make it accessible from outside the cluster.
kubectl get services
I get a list of services and the local IP address and port on which they are exposed.
I can get the same information on the dashboard
The IP address where the VirtualBox VM can be accessed is 192.168.99.100 – as can be seen for example from the URL where the dashboard application is accessed:
The nginx service can now be accessed at 192.168.99.100:32178
And in the browser:
