🛠 Prerequisites:

• OpenShift cluster (Local or Cloud)
• oc CLI installed
• Basic access (developer/admin rights)
• DockerHub or Red Hat certified WordPress container access
• (Optional) OpenShift Web Console access

---

🔥 Step 1: Login to OpenShift Cluster

oc login --token=<your-token> --server=https://api.<cluster-domain>:6443
Code language: HTML, XML (xml)

Or via the Web Console.

---

🏗 Step 2: Create a New Project (Namespace)

oc new-project wordpress-demo
Code language: JavaScript (javascript)

(You can also create it from Web Console: Projects > Create Project.)

---

📦 Step 3: Deploy MySQL Database (for WordPress backend)

WordPress needs a database. Let’s deploy a simple MySQL Pod + Service.

a) Create a Secret for MySQL Passwords

oc create secret generic mysql-pass --from-literal=password=Wordpress@123
Code language: JavaScript (javascript)

b) Deploy MySQL using a Template or YAML

Here’s a sample YAML to create MySQL:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mysql
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
      - name: mysql
        image: mysql:5.7
        env:
        - name: MYSQL_ROOT_PASSWORD
          valueFrom:
            secretKeyRef:
              name: mysql-pass
              key: password
        - name: MYSQL_DATABASE
          value: wordpress
        ports:
        - containerPort: 3306
        volumeMounts:
        - name: mysql-persistent-storage
          mountPath: /var/lib/mysql
      volumes:
      - name: mysql-persistent-storage
        emptyDir: {}
---
apiVersion: v1
kind: Service
metadata:
  name: mysql
spec:
  ports:
  - port: 3306
  selector:
    app: mysql
Code language: JavaScript (javascript)

Apply it:

oc apply -f mysql.yaml
Code language: CSS (css)

✅ Now you have a MySQL backend running!

🌟 Step 4: Deploy WordPress Application

a) Deploy WordPress using YAML

Here’s a WordPress Deployment YAML:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: wordpress
spec:
  replicas: 1
  selector:
    matchLabels:
      app: wordpress
  template:
    metadata:
      labels:
        app: wordpress
    spec:
      containers:
      - name: wordpress
        image: wordpress:latest
        env:
        - name: WORDPRESS_DB_HOST
          value: mysql
        - name: WORDPRESS_DB_PASSWORD
          valueFrom:
            secretKeyRef:
              name: mysql-pass
              key: password
        ports:
        - containerPort: 80
        volumeMounts:
        - name: wordpress-persistent-storage
          mountPath: /var/www/html
      volumes:
      - name: wordpress-persistent-storage
        emptyDir: {}
---
apiVersion: v1
kind: Service
metadata:
  name: wordpress
spec:
  ports:
  - port: 80
  selector:
    app: wordpress
Code language: JavaScript (javascript)

Apply it:

oc apply -f wordpress.yaml
Code language: CSS (css)

✅ Now WordPress Pod + Service are deployed!

---

🌍 Step 5: Expose WordPress to Public

Expose WordPress Service via Route (URL):

oc expose service wordpress

This will automatically create a Route.

📍 You can get the URL:

oc get route wordpress
Code language: JavaScript (javascript)

Example output:

NAME        HOST/PORT                         PATH   SERVICES    PORT   TERMINATION   WILDCARD
wordpress   wordpress-demo.apps.cluster.com          wordpress   80                   None

Visit the URL in your browser — you’ll see the WordPress Installation Page 🎉

📈 Full Deployment Map:

Component	Deployed As	Notes
MySQL Database	Deployment + Service + Secret	WordPress backend
WordPress Site	Deployment + Service + Route	Frontend exposed to public

---

💬 Final Words:

✅ This is the simplest, fastest OpenShift WordPress demo. ✅ For Production:

• Use Persistent Volumes (PVCs) instead of emptyDir.
• Secure MySQL and WordPress (TLS, strong passwords).
• Set Resource limits (CPU, Memory).
• Scale Replicas.
• Use OpenShift templates or Helm Charts.

📦 Bonus: One-Line Deployment (S2I)

You can also deploy WordPress from Source using OpenShift templates:

oc new-app wordpress
Code language: JavaScript (javascript)
