Overview
Minikube is a tool that installs Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a VM on the local development machine. To install it, it requires virtualization extensions enabled in your system's BIOS.
Installation
Latest Version
Mac
brew install minikube
The installation will automatically add a "minikube" context.
Uninstallation
brew uninstall minikube
Note that uninstallation does not clean the context.
Linux
Dependencies: minikube 1.18 and newer require installing conntrack:
Delete the old minikube, if any.
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo mv ./minikube-linux-amd64 /usr/local/bin/minikube
chmod a+x /usr/local/bin/minikube
Before starting the new minikube, remove or backup old ~/.minikube.
Then:
minikube start
Uninstall followed by Installation
Uninstall the old minikube. Become root:
sudo su
As root:
minikube stop
minikube delete --all --purge
rm -rf /root/.kube /root/.minikube /home/ec2-user/.kube /home/ec2-user/.minikube
rm /usr/local/sbin/minikube
rm /usr/local/sbin/kubectl
Uninstall the new minikube. As root:
cd /tmp
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
mv ./minikube-linux-amd64 /usr/local/sbin/minikube
chmod a+x /usr/local/sbin/minikube
curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
mv ./kubectl /usr/local/sbin/kubectl
chmod a+x /usr/local/sbin/kubectl
