NGINX PHP 7 K8S Deployment

What is this?

A simple template for starting a PHP 7 application served by NGINX, using Kubernetes (K8S) deployment object. This also works with Minikube, to aid in learning how to use K8S on a local machine.

How does it work?

Locally via Minikube

1. Start Minikube:

   $ minikube start
   Starting local Kubernetes cluster...
   Kubectl is now configured to use the cluster.

   Optional: Use xhyve driver for Docker instead of Virtualbox.

   • Follow Minikube documentation on installing the xhyve driver.

   • Pass the --vm-driver argument to "Start Minikube".

     minikube start --vm-driver=xhyve

2. Create a K8S service:

   $ kubectl create -f resources/kubernetes/services/local-service.yaml
   service "local-service" created

3. Create a K8S deployment:

   $ kubectl create -f resources/kubernetes/deployments/local-deployment.yaml
   deployment "local-deployment" created

   Optional: Mount local work into the container.

   • Add the a volume info to resources/kubernetes/deployments/local-deployment.yaml:

             image: rabellamy/php7:0.1.0
             ports:
             - containerPort: 9000
     +        volumeMounts:
     +        - mountPath: /var/www/html
     +          name: src
     +      volumes:
     +      - name: src
     +        hostPath:
     +          path: /PATH/TO/NGINX-PHP-7-K8S-Deployment/src

4. Get the URL for the NGINX service that will serve your PHP 7 app:

   $ minikube service nginx-service --url

   Note, you may see this message until the pods are ready:

   Waiting, endpoint for service is not ready yet...

5. Clean up when you're done:

   $ minikube delete
   Deleting local Kubernetes cluster...
   Machine deleted.

Why?

We wanted an example of an NGINX and PHP 7 template using the Kubernetes deployment object, and straight K8S configs, but to our knowledge none previously existed. Here you go!

For a templatized solution, consider Helm Charts.
