# Deployment of a Kubernetes Cluster with Kubespray
This project automates the deployment of a kubernetes cluster with kubespray in Test environment.
Ansible and bash scripts are used to setup a kubernetes cluster.
Vagrant is utilized to provision VMs.
### Requirements
- Minimum required version of Kubernetes is **`v1.27`**
- **`Ansible v2.14+`**, **`Jinja 2.11+`** and **`python-netaddr`** is installed on the machine that will run Ansible commands.
- The target servers must have access to the Internet in order to pull docker images. Otherwise, additional configuration is required.
Get [Chocolatey](https://chocolatey.org/install) and use it to install vagrant:
```bash
choco install vagrant
```
### Getting Started
Provision vagrant VMs
```bash
vagrant up
```
Login to `control` VM
```bash
vagrant ssh control
```
Change password of `root` user
This new password will be required when public RSA keys are being transferred to kube nodes.
```bash
sudo passwd
```
Update yum package manager
```bash
cd /
yum update
```
Install Git
```bash
yum install git
```
Clone this repo to `/` directory in control node
```bash
git clone [email protected]:odennav/kubespray-bash-ansible.git
```
Clone kubernetes-sigs kubespray repo to `/` directory in control node
```bash
git clone [email protected]:kubernetes-sigs/kubespray.git
```
Run `dependencies-install.sh` script in `control` node to install necessary dependencies, update yum package index and ensuring python version compatibility.
```bash
chmod 770 dependencies-install
./dependencies-install
```
Setup system for Ansible playbook execution
This bash script copies SSH keys, updates Ansible inventory, builds host inventory manifest and installs kubectl.
```bash
chmod 770 k8s-env-build.sh
./k8s-env-build.sh
```
Run Ansible playbook to to deploy kubernetes cluster
Change directory to your local kubespray repository and execute `cluster.yml` ansible playbook
```bash
cd /kubespray
ansible-playbook -i inventory/mycluster/hosts.yaml --become --become-user=root cluster.yml
```
### Reset Kubernetes Cluster
To remove current kubernetes cluster, run playbook as root user.
Run this command in kubespray directory
```bash
cd /kubespray
ansible-playbook -i inventory/mycluster/hosts.yaml --become --become-user=root reset.yml
```
### Destroying Resources(Optional)
To destroy the VMs created by vagrant.
```bash
vagrant destroy
```
