[Kubernetis] Building a MiniKube Environment on a Single Node

Hello neighbors ^.^
Good morning, sir.

Today, we're going to install a minikube on a single node and build a Kubernetis lab environment
I'll post about how. This procedure is based on uuntu.
 
1. Installing Minikube
Minikube is a tool that can be made in Kubernetis environment.
Then, I will try to install Minukube through the procedure below.
1) Update the version of the tool using the command below.

ubuntu@ip-172-31-31-84:~$ sudo apt-get update

2. Install Kubectl.
1) Download kubectl and proceed with the installation using the command below.
curl -LO https://dl.k8s.io/release/v1.23.0/bin/linux/amd64/kubectl
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl sudo apt-get install conntrack
 

ubuntu@ip-172-31-31-84:~$ curl -LO https://dl.k8s.io/release/v1.23.0/bin/linux/amd64/kubectl

ubuntu@ip-172-31-31-84:~$

 

2) Check the kubectlversion.
 kubectl version --output yaml

ubuntu@ip-172-31-31-84:~$ kubectl version --output yaml
clientVersion:
  buildDate: "2021-12-07T18:16:20Z"
  compiler: gc

  gitVersion: v1.23.0
  goVersion: go1.17.3
  major: "1"
  minor: "23"
  platform: linux/amd64

The connection to the server localhost:8080 was refused - did you specify the right host or port?
ubuntu@ip-172-31-31-84:~$

3) For the automatic completion of the Bash function, set it as follows

ubuntu@ip-172-31-23-60:~$ echo 'source <(kubectl completion bash)' >>~/.bashrc
ubuntu@ip-172-31-23-60:~$ echo 'alias k=kubectl' >>~/.bashrc
ubuntu@ip-172-31-23-60:~$ echo 'complete -o default -F __start_kubectl k' >>~/.bashrc
ubuntu@ip-172-31-23-60:~$ exec bash

3. Install Helm.
Helm is a package management tool that allows you to install Kubernetis' resources at once.
1) Install Helm using the command below.
 
curl -LO https://get.helm.sh/helm-v3.11.0-linux-amd64.tar.gz
tar -zxvf helm-v3.11.0-linux-amd64.tar.gz
sudo mv linux-amd64/helm /usr/local/bin/helm

ubuntu@ip-172-31-31-84:~$ curl -LO https://get.helm.sh/helm-v3.11.0-linux-amd64.tar.gz

ubuntu@ip-172-31-31-84:~$ sudo mv linux-amd64/helm /usr/local/bin/helm

 
3. Install Helm.
Helm is a package management tool that allows you to install Kubernetis' resources at once.
1) Install Helm using the command below.

ubuntu@ip-172-31-31-84:~$ helm version
version.BuildInfo{Version:"v3.11.0", GitCommit:"472c5736ab01133de504a826bd9ee12cbe4e7904", GitTreeState:"clean", GoVersion:"go1.18.10"}
ubuntu@ip-172-31-31-84:~$

We have now installed all Kubernetis environments in one node.
Then you can proceed with the test you want.
