How to Deploy WordPress on Kubernetes

Overview

Running WordPress on Kubernetes gives you scalability, easy updates, and self-healing capabilities on your Breeze. This guide uses Helm to deploy WordPress with a MySQL backend.

Prerequisites

• K3s or MicroK8s running on your Breeze
• Helm installed
• A default StorageClass available

Deploy with Helm

helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update

helm install wordpress bitnami/wordpress \
  --set wordpressUsername=admin \
  --set wordpressPassword=YourSecurePassword \
  --set wordpressEmail=you@yourdomain.com \
  --set service.type=NodePort \
  --set persistence.size=10Gi \
  --set mariadb.primary.persistence.size=5Gi \
  --set resources.requests.memory=256Mi \
  --set resources.requests.cpu=200m

Check the Deployment

kubectl get pods -l app.kubernetes.io/name=wordpress
kubectl get svc wordpress

Access WordPress

export NODE_PORT=$(kubectl get svc wordpress -o jsonpath='{.spec.ports[?(@.name=="http")].nodePort}')
echo "http://your-breeze-ip:$NODE_PORT"

Add Ingress with SSL

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: wordpress-ingress
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-prod
spec:
  ingressClassName: nginx
  tls:
    - hosts:
        - blog.yourdomain.com
      secretName: wordpress-tls
  rules:
    - host: blog.yourdomain.com
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: wordpress
                port:
                  number: 80

Upgrade WordPress

helm upgrade wordpress bitnami/wordpress -f values.yaml

Kubernetes ensures WordPress stays running and recovers automatically from failures on your Breeze.
