# Installing Kubernetes the kubeadm way on Apple Silicon

In here is the setup specific to Apple Silicon (M1/M2) Macs. VirtualBox currently does not have good support for these Macs, therefore we will create the Ubuntu virtual machines using Multipass.

## Prerequisites

* Apple M1 or M2 system
* 8GB RAM (16GB preferred).
    * All configurations - One control plane node will be provisioned - `kubemaster`
    * If you have less than 16GB then only one worker node will be provisioned - `kubeworker1`
    * If you have 16GB or more then two workers will be provisioned - `kubeworker01` and `kubeworker2`

You'll need to install the following first.

* Multipass - https://multipass.run/install. Follow the instructions to install it and check it is working properly. You should be able to successfully create a test Ubuntu VM following their instructions. Delete the test VM when you're done.
* JQ - https://github.com/stedolan/jq/wiki/Installation#macos

Additionally

* Your account on your Mac must have admin privilege and be able to use `sudo`

When i am trying to run the below command on Worker node , getting below error:
Commands: Kubectl get pods commands
Error:
E0107 22:09:01.940152 5697 memcache.go:265] couldn’t get current server API group list: Get “http://localhost:8080/api?timeout=32s”: dial tcp [::1]:8080: connect: connection refused

On Master Node everything is working fine, Looks like the worked node not able to connect with APIServer on Master node.
Could you please help me on this one.
thanks in advance.

Sounds like you did not create a kubeconfig file on that worker node; the localhost:8080 related error is what you get when the file does not exist.

It is generally not preferred practice to execute kubectl commands from worker nodes. In fact many installations don’t bother to install kubectl on them, and I probably should not have when building this lab.
