This proxy was made to work with Kubernetes from the start, so you should be able to get a service up and running by applying prismic.yml:
- Get a copy of
prismic.yml - Customize it as needed, replacing at least the following values:
<PROXY-HOST>: the actual host for your proxy, i.e.content.my-site.com<PRISMIC-REPO-NAME>: name of your repository, which is whatever comes before.cdn.prismic.io
kubectl apply -f prismic.yml
This should give you a deployment, service and ingress to expose your newly created proxy.
