TL;DR: Install Minikube on Ubuntu 22.04
This post serves as a quick reference for installing Minikube on Ubuntu 22.04. It is not a wholistic replacement for the official Minikube documentation on this subject, but serves as a quick summary of the steps.
Prerequisites
This post assumes that you already have Docker installed on your Ubuntu 22.04 system. If this is not the case, reference the “TL;DR: Install Docker on Ubuntu 22.04” post.

sudo install minikube-linux-amd64 /usr/local/bin/minikube
minikube version
minikube start --cpus=4 --memory=6g --addons=ingress
alias kubectl="minikube kubectl --"
kubectl version --short
Minikube should now be installed on your Ubuntu 22.04 system, and a cluster with access to 4 CPUs and 6 gigabytes of memory should be running.

Start Minikube Cluster
Use the minikube start command to start a Minikube cluster. The below example starts a cluster with access to 4 CPUs and 6 gigabytes of memory. It also enables the ingress addon, which allows us to access services deployed within the Minikube cluster.

💡 kubectl not found. If you need it, try: 'minikube kubectl -- get pods -A'
🏄 Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default
Add kubectl Alias
Set up an alias for your current shell session that allows you to execute kubectl commands against the Minikube cluster without needing to prepend the minikube command.
1
alias kubectl="minikube kubectl --"
Note that this command will need to be executed on each unique shell session to the system. If you’d like to avoid this, add this command to your shell’s configuration file (e.g. ~/.bashrc, ~/.bash_profile, ~/.profile, etc.).
Example output of this command is below:

christopher@awx:~$ kubectl version --short
Command 'kubectl' not found, but can be installed with:
sudo snap install kubectl
christopher@awx:~$
christopher@awx:~$ alias kubectl="minikube kubectl --"
christopher@awx:~$
christopher@awx:~$ kubectl version --short
Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
