# k8s-varnish-nginx

This repository domonstrates how to deploy Varnish, a high-performance caching HTTP reverse proxy, on Kubernetes.

## Deployment

Apply manifests:

```bash

kustomize build manifests | kubectl apply -f -

```

## Testing

Open port-forward to varnish service:

```bash

kubectl -n demo port-forward svc/varnish 8008:80

```

Test whether caching works:

```bash

curl -v http://localhost:8008

```

Example of a successful response:

```

*   Trying 127.0.0.1:8008...

* Connected to localhost (127.0.0.1) port 8008 (#0)

> GET / HTTP/1.1

> Host: localhost:8008

> User-Agent: curl/7.79.1

> Accept: */*

> 

* Mark bundle as not supporting multiuse

< HTTP/1.1 200 OK

Welcome to nginx!

If you see this page, the nginx web server is successfully installed and

working. Further configuration is required.

Thank you for using nginx.


* Connection #0 to host localhost left intact

```

We can see that Varnish has cached the Nginx welcome page for us, resulting in `X-Cache: cached` and `X-Cache-Hits: 3`.
