Minikube

• Part of the Kubernetes ecosystem
• “Minikube is a lightweight Kubernetes implementation that creates a VM on your local machine and deploys a simple cluster containing only one node.”

Need these:

• 2 CPUs or more
• 2GB of free memory
• 20GB of free disk space
• docker ( or other container or vm manager )

Install Minikube:

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube_latest_amd64.deb
sudo dpkg -i minikube_latest_amd64.deb

Start cluster:

minikube start

Access cluster with mini kubectl:

kubectl get po -A                # if you already have kubectl
minikube kubectl -- get po -A    # have minikube install kubectl

Create an alias for kubectl:

~/.bashrc


alias kubectl="minikube kubectl --"

Source it to apply imediately:

source ~/.bashrc

Start dashboard:

minikube dashboard

Create and expose hello world deployment:

kubectl create deployment hello-minikube --image=kicbase/echo-server:1.0
kubectl expose deployment hello-minikube --type=NodePort --port=8080

… wait for it to start ….

Check it:

kubectl get services hello-minikube

Let minikube launch a browser:

minikube service hello-minikube

Forward the port:

kubectl port-forward service/hello-minikube 7080:8080

Access it here: http://localhost:7080/

minikube pause       # pause cluster
minikube unpause     # unpause cluser
minikube stop        # stop cluster
minikube config set memory 9001    # change default memory limit
minikube addons list               # see service catalog

Run another cluster with a specific ( old ) version:

minikube start -p aged --kubernetes-version=v1.16.1

Delete all clusters:

minikube delete --all
