Kubernetes Cluster Setup Methods 🚀

Minikube Setup 🐳

Repository: Terraform Kubernetes Cluster (opens in a new tab)
- Description: Use Terraform to automate the setup of a Kubernetes cluster.
- Steps:
  1. Clone the repository:
```
git clone https://gitlab.com/self-made-projects/terraform-k8s-cluster.git
```
  2. Navigate to the repository directory:
```
cd terraform-k8s-cluster
```
  3. Initialize Terraform:
```
terraform init
```
  4. Apply the Terraform configuration:
```
terraform apply
```
  5. Follow the prompts to complete the setup.

Vagrant: Automates VM setup for a consistent development environment.
- Steps:
  1. Create a Vagrantfile to define VM configurations.
  2. Run vagrant up to create and configure the VMs.
  3. SSH into each VM using vagrant ssh <vm-name>.
  4. Install kubeadm, kubelet, and kubectl on each VM:
```
sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl
```
  5. Initialize the Kubernetes cluster on the master node:
```
sudo kubeadm init
```
  6. Follow the post-installation instructions to set up kubectl for the non-root user and join worker nodes to the cluster.

VMware: Use VMware to create and manage VMs for a Kubernetes cluster.
- Steps:
  1. Create VMs in VMware for master and worker nodes.
  2. SSH into each VM and install Docker:
```
sudo apt-get update
sudo apt-get install -y docker.io
```
  3. Install kubeadm, kubelet, and kubectl:
```
sudo apt-get install -y apt-transport-https ca-certificates curl
sudo curl -fsSL https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
sudo apt-add-repository "deb http://apt.kubernetes.io/ kubernetes-xenial main"
sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl
```
  4. Initialize the Kubernetes cluster on the master node:
```
sudo kubeadm init
```
  5. Follow the post-installation instructions to set up kubectl for the non-root user.
  6. Join worker nodes to the cluster using the kubeadm join command provided by the master node after initialization.

Minikube: Quick and easy setup for local Kubernetes clusters.
Terraform: Automates Kubernetes cluster setup, suitable for cloud environments.
Vagrant: Consistent development environment setup using VMs.
VMware: Manual setup providing flexibility and control over VM configurations.
