# ⚓️ WordPress Deployment on Kubernetes Cluster
This project demonstrates the deployment of a **WordPress application** with a **MySQL database** on a Kubernetes cluster using `kubeadm`. It covers the setup of namespaces, deployments, services, and ConfigMaps to ensure a smooth and secure deployment.
---
## 📚 Project Overview
### 1. ✅ Launching EC2 Instances
- Launched **3 EC2 instances** using `t2.medium` type.
- OS: **Ubuntu 22.04 LTS**
### 2. ⚡ Kubernetes Cluster Setup
- Set up the Kubernetes cluster using [`kubeadm`](https://github.com/Aareez01/kubernetes-v1.30.2-cluster-using-kubeadm).
- Followed steps to install Kubernetes v1.30.2 and configure the control plane and worker nodes.
---
## 🎯 Expected Outcomes
- ✅ Successful deployment of WordPress and MySQL on a Kubernetes cluster.
- ✅ Proper configuration of namespaces, deployments, services, and ConfigMaps.
- ✅ Secure and seamless communication between WordPress and MySQL using Kubernetes services.
- ✅ WordPress accessible via the public IP or domain on port 30080 using NodePort.
- ✅ Hands-on experience in managing containerized applications and using kubeadm for cluster setup.
- ✅ Done! WordPress is now successfully deployed on your Kubernetes cluster! 🎉
---
## 🎯 Objective
To deploy a WordPress application connected to a MySQL database using Kubernetes, ensuring secure communication and scalability.
---
## ⚙️ Kubernetes Configuration
### 1. 🗂️ Create Namespace
```bash
kubectl create ns mywebsite
```
### 2. 🛢️ MySQL Deployment
Create a `mysql.yaml` file:
```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: mysql
namespace: mywebsite
spec:
replicas: 1
selector:
matchLabels:
app: mysql
template:
metadata:
labels:
app: mysql
spec:
containers:
- name: db
image: mysql
env:
- name: MYSQL_ROOT_PASSWORD
value: "redhat"
- name: MYSQL_DATABASE
value: "bigdata"
```
### 3. 🧩 MySQL Service (ClusterIP)
```bash
kubectl expose deployment -n mywebsite mysql --port 3306 --target-port 3306 --name=mysql-svc
```
---
### 4. 🌐 WordPress Deployment
Create a `wordpress.yaml` file:
```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: wordpress
namespace: mywebsite
spec:
replicas: 1
selector:
matchLabels:
app: wordpress
template:
metadata:
labels:
app: wordpress
spec:
containers:
- name: wp
image: wordpress
env:
- name: WORDPRESS_DB_HOST
value: "10.96.164.193"
- name: WORDPRESS_DB_USER
value: "root"
- name: WORDPRESS_DB_PASSWORD
value: "redhat"
- name: WORDPRESS_DB_NAME
value: "bigdata"
```
### 5. 🌐 WordPress Service (NodePort)
Create `wp-svc.yaml`:
```yaml
apiVersion: v1
kind: Service
metadata:
name: wp-svc
namespace: mywebsite
spec:
selector:
app: wordpress
type: NodePort
ports:
- protocol: TCP
port: 80
targetPort: 80
nodePort: 30080
```
---
## ⚡ Access WordPress in Browser
```bash
http://:30080
```
---
## 🛠️ ConfigMap for Environment Variables
### 1. 📄 Create MySQL ConfigMap
```bash
kubectl create configmap app-db --from-literal=MYSQL_ROOT_PASSWORD=redhat --from-literal=MYSQL_DATABASE=bigdata -n mywebsite
```
### 2. 📄 Create WordPress ConfigMap
```bash
kubectl create configmap app-wp -n mywebsite \
--from-literal=WORDPRESS_DB_HOST=10.110.46.197 \
--from-literal=WORDPRESS_DB_USER=root \
--from-literal=WORDPRESS_DB_PASSWORD=redhat \
--from-literal=WORDPRESS_DB_NAME=bigdata
```
---
## 🚀 Using ConfigMap in Deployment
Modify the environment section of your deployment file to reference the ConfigMap:
```yaml
envFrom:
- configMapRef:
name: app-db
- configMapRef:
name: app-wp
```
---
## 📡 Verifying Deployment
1. Check if all pods are running:
```bash
kubectl get pods -n mywebsite
```
2. Verify services:
```bash
kubectl get svc -n mywebsite
```
3. Access WordPress via browser:
```
http://:30080
```
---
## 📝 Conclusion
- ✅ Successfully deployed a WordPress application with a MySQL backend on a Kubernetes cluster.
- ✅ Used ConfigMaps to manage configuration, ensuring application portability and better management.
