Installing Docker with Kubernetes and Helm

Installing Docker

Step 1: Remove old versions of Docker if they've previously been installed:
```
sudo apt-get remove docker docker-engine docker.io containerd runc
```

Step 2: Install packages that allow APT to use HTTPS:

$ sudo apt-get update
$ sudo apt-get install -y \
  apt-transport-https \
  ca-certificates \
  curl \
  gnupg-agent \
  software-properties-common

Step 3: Add Docker's GPG key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Step 4: Add the Docker repository:

sudo add-apt-repository \
     "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
     $(lsb_release -cs) \
     stable"

Step 5: Install the Docker engine:

$ sudo apt-get update
$ sudo apt-get install -y docker-ce docker-ce-cli containerd.io

Step 6: Add your login to the Docker group:
```
sudo usermod -aG docker $USER
```
Step 7: Logout of your SSH session and log back in for the changes to take effect.
Step 8: Verify the engine is installed correctly:
```
docker run hello-world
```

Install Docker Compose

Docker Compose is a tool for configuring an app's services with a YAML file to define and run multi-container Docker applications.

sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Step 2: Make the app executable:

sudo chmod +x /usr/local/bin/docker-compose

Step 3: Test the installation:
```
docker-compose --version
```

Install kubectl

Step 2: Make the app executable:
```
sudo chmod +x /usr/local/bin/kubectl
```
Step 3: Test the installation:
```
kubectl version --short --client
```

Install minikube

Step 1:

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64;
sudo install minikube-linux-amd64 /usr/local/bin/minikube;

Step 2:

Step 3: If you get any error regarding drivers just got to this link
Step 4: check installation by running
```
minikube version
```

Install KinD

Kubernetes-in-Docker (KinD) is a tool for running local Kubernetes clusters using Docker container "nodes".

Step 1: Download KinD:

sudo curl -L "https://kind.sigs.k8s.io/dl/v0.8.1/kind-$(uname)-amd64" -o /usr/local/bin/kind

Step 2: Make the app executable:
```
sudo chmod +x /usr/local/bin/kind
```
Step 3: Test the installation:
```
kind get clusters
```

Installing helm v3:

Step 1: Download the specific version from here
Step 2: Open your terminal and go to the path where you have downloaded the tar.gz file
Step 3: Unpack it using
```
tar -zxvf <file_name>.tar.gz
```
Step 4: Move helm unpacked file to its desired destination using
```
mv linux-amd64/helm /usr/local/bin/helm
```

Uninstalling Kubernetes

Just run these few simple commands in your terminal:
