Install kubectl

Download the latest Kubectl release with the command:

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

chmod +x kubectl

sudo mv kubectl /usr/bin/

Test to ensure the version you installed is up-to-date:

kubectl version

Kubectl autocomplete

BASH

source <(kubectl completion bash) # setup autocomplete in bash into the current shell, bash-completion package should be installed first.
echo "source <(kubectl completion bash)" >> ~/.bashrc # add autocomplete permanently to your bash shell.

You can also use a shorthand alias for kubectl that also works with completion:

alias k=kubectl
complete -o default -F __start_kubectl k

ZSH

source <(kubectl completion zsh)  # setup autocomplete in zsh into the current shell
echo '[[ $commands[kubectl] ]] && source <(kubectl completion zsh)' >> ~/.zshrc # add autocomplete permanently to your zsh shell

Install Kubernetes using Minikube

To install the latest minikube stable release on x86-64 Linux using Debian package:

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube_latest_amd64.deb

sudo dpkg -i minikube_latest_amd64.deb

Start the Cluster

Start your minikube cluster with one master node using the following command.

We are using Flannel Plugin for Networking, NetworkPolicy Management, Traffic Management

minikube start

minikube status

Congratulations you now have a minikube cluster.

Enable Metrics Server

minikube addons enable metrics-server

Ensure your Master Node is in Healthy State and all the necessary services and pods are working fine.

Worker Nodes Creation

Note: This as an optional step, you can safely skip this step if you do not require an additional worker node.

minikube node add --worker=true

Now login to the Worker node and then pull all the latest images that are required.

You can use the same script that is used in the Master Server from the above section.

Verify nodes using the following command

kubectl get nodes

Repeat the above steps, if you want to add more worker Nodes.

Kubectl context and configuration

Show Merged kubeconfig settings.

kubectl config view

Display list of contexts

kubectl config get-contexts
