Steps to Install Popular Kubernetes Distros

We'll explore the installation process of each distro, enjoy the journey through creating Kubernetes clusters using some bash scripts I created for you! Download the scripts below. 👇🏽

I decided to use plain bash scripts to remove any additional complexity in installing Ansible, Terraform, Argo, or other tools and external dependencies like Python, or external libraries, which also would remove the fat that consumes extra resources: CPU, RAM, and disk space that you may need to install the distros.

Click on each of the tabs to complete the whole installation. I have tried to separated each tab depending on the different goals.

Follow the video above for specifics.

K0s Master

# download the K0s binary
curl -sSLf https://get.k0s.sh | sudo sh
# install K0s
k0s install controller --enable-worker
systemctl daemon-reload
k0s start
# check the status
k0s status
k0s kubectl get nodes
watch 'k0s kubectl get pod --all-namespaces'
k0s kubectl get nodes
# create a token to join workers to the cluster
k0s token create --role=worker > token-file

K0s Worker

# download the K0s binary
curl -sSLf https://get.k0s.sh | sudo sh
# install K0s
k0s install worker --token-file token-file
systemctl daemon-reload
k0s start
# check the status
k0s status

K3s Master

# install K3s
curl -sfL https://get.k3s.io | sh - 
# Check for Ready node, takes ~30 seconds 
k3s kubectl get nodes 
# Check for Ready pod, takes ~60 seconds
watch 'k3s kubectl get pod --all-namespaces'
# get the token to join workers to the cluster
cat /var/lib/rancher/k3s/server/node-token

K3s Worker

curl -sfL https://get.k3s.io | K3S_URL=https://k3s1-rebelion:6443 K3S_TOKEN=mynodetoken INSTALL_K3S_EXEC="agent" sh -

#agent node is not joining the cluster - Workaround:
sudo systemctl stop k3s
#start the agent in the background
sudo k3s agent --server https://k3s1-rebelion:6443 -t mynodetoken --disable-apiserver-lb > /dev/null 2>&1 &

Microk8s Master

# install snapd
apt update
apt install snapd
# install microk8s
snap install microk8s --classic
# Run the command and store the output
join_command=$(microk8s add-node | tail -n 1) 
echo $join_command --worker

Microk8s Worker

#install snapd
sudo apt update
sudo apt install snapd
#install microk8s
sudo snap install microk8s --classic
#join the cluster, with output from the previous step
sudo $join_command

microk8s kubectl get nodes

Minikube

multipass provides a VM image with minikube pre-installed, so we can use it to create a VM with minikube pre-installed.

The bad news is that minikube VM image requires at least 2 CPUs, 4GB of RAM, and 40GB of disk space, huge compared to the other distros! 🐳

# create the VM with minikube pre-installed
multipass launch --name minikube-rebelion -c 2 -m 4G -d 40G minikube
multipass exec minikube-rebelion -- minikube start --nodes 3 -p la-rebelion-cluster
