# Kubernetes Init Cluster
**Kubernetes-init-cluster** is a **BASH** script that can be used to provision 3 instances on aws with bash & terraform then initialize the infrastructure using ansible playbooks.
You can take a look at the [GitHub project page](https://github.com/Osama-Yusuf/Kubernetes-init-cluster).
---
## Getting started:
### Prerequisites:
- Terraform
```
source <(curl -s https://raw.githubusercontent.com/Osama-Yusuf/Linux-Apps-Installation-Scripts/main/DevOps/terraform.sh)
```
- Ansible
```
sudo apt-add-repository ppa:ansible/ansible
sudo apt update
sudo apt install ansible
```
- AWS CLI
```
curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip" && unzip awscliv2.zip
sudo ./aws/install && rm -rf aws awscliv2.zip
```
- [AWS Account](https://aws.amazon.com/premiumsupport/knowledge-center/create-and-activate-aws-account/)
- [Create an IAM User](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_create.html)
- [Configure the AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html)
### Install:
```
git clone https://github.com/Osama-Yusuf/Kubernetes-init-cluster.git
cd Kubernetes-init-cluster && chmod +x hostname.sh
```
### Usage:
```
./hostname.sh [OPTION]
-y Provision infra with terraform, else you will be prompted for ips, keys, etc.
-d Delete all files created by hostname.sh (ansible, inventory, etc.) else you will use them if they exist
Example: ./hostname.sh -y -d
```

## What it does:
### 1. Provisions 3 "t2.medium" ec2's using terraform
- #### Creates a key if not exists
- #### query default vpc & security group ids
- #### query ubuntu 20.04 ami in current region
- #### Then It creates 3 ec2's by for-looping these strings (master, worker1, worker2)
### 2. Then it initializes the cluster using bash script & ansible playbooks by:
- #### creating inventory file and hosts file to be copied to all nodes in the cluster
- #### and install & initialize kubeadm & kubectl with k8s_init.sh script also copied to all nodes and then executed using ansible playbook
- #### then it creates kubeadm token file on the master node
- #### then it copies the token to the worker nodes and executes it
- #### after that the playbook apply the calico network plugin
### After execution 3 instances will be up & running on aws (master, worker1, & worker2) initialized with kubeadm & kubectl
### Then it will ssh into master node for you to start working/studying k8s
