minikube on Linux arm64

minikube setup based on ubuntu-20.04-arm64 running as a Vagrant Virtual Machine with the Parallels provider.

Applications

• Docker
• Docker Compose
• minikube

Just start

Start the Virtual Machine

vagrant up

SSH into the Virtual Machine

vagrant ssh

Launch minikube

minikube start --kubernetes-version=v1.25.3

Install kubectl

curl -LO https://dl.k8s.io/release/v1.25.3/bin/linux/arm64/kubectl

curl -LO https://dl.k8s.io/release/v1.25.3/bin/linux/arm64/kubectl.sha256
echo "$(cat kubectl.sha256)  kubectl" | sha256sum --check

sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

Operations

Get all running pods!

kubectl get pods -A

Create a job

kubectl create job hello --image nixery.dev/arm64/shell -- echo "Hello World"

Expose Kubernetes API using kubectl proxy

kubectl proxy --port=8080 --address=0.0.0.0 --accept-hosts='.+'

Test Kubernetes API from the host machine

curl http://localhost:8080/apis

Programming (Go)

The src directory contains an simple program using the client-go library, to talk with the Kubernetes API and list the existing jobs in the default namespace.

To create the program binary run (from the src directory):

GOOS=linux go build -o jobs main.go

in the host machine and execute the following in the guess one:

/vagrant/src/jobs

the output should be similar to:

hello

the name of the Job created before in the default namespace.
