Docker repo: https://hub.docker.com/repository/docker/downey/web-monetization-proxy

Simple proxy for injecting Web Monetization meta tags. Intended to be deployed as a sidecar process alongside Web Monetization unaware webapps.

This proof-of-concept project was created for fun as part of the DEV "Grant For The Web" Hackathon. It should not be relied on for production use cases and merely exists to demonstrate what is possible. In the future it might be worth exploring doing something similar using Envoy proxies and a WASM plugin that implements this functionality.

The proxy relies on the following environment variables:

• PROXY_PORT -- the port the proxy listens on
• BACKEND_PORT -- the port of the backend application that requests are forwarded to
• PAYMENT_POINTER -- an Interledger Payment Pointer string

Reference the example Deployment to see how you might configure these in Kubernetes.

This project uses Go modules which work best with Golang 1.13+. To run the project's tests, run go test ./... from the root directory.

This project uses Cloud Native Buildpacks and the pack cli in lieu of a Dockerfile. New images can be built by running the following:

pack build <image-name-here> -B cloudfoundry/cnb:bionic

To ease development and deployment to Kubernetes, it also includes some kbld configuration in the build directory and a sample Kubernetes Deployment in the hack directory.

To quickly build, push, and deploy to Kubernetes run¹:

kbld -f hack -f build | kubectl apply -f -

¹ - You will need to update build/destinations.yaml to refer to an OCI image registry you have permission to push to and replace hack/example-ingress.yaml with Ingress configuration that is valid for your cluster.
