Provides a Docker image for hosting a reverse proxy to Posthog based on Caddy (alpine).

Based on the following documentation: https://posthog.com/docs/integrate/proxy

Note that this expects traffic from port 8080. In order to get this to work on Azure App Services, make sure to create a corresponding environment variable / Application Setting:

Name: WEBSITES_PORT

Value: 8080

Caddy is configured to point to eu.posthog.com. If you have Posthog Cloud hosted in US, make sure to change the corresponding line within Caddyfile to app.posthog.com.

This will expose your container on localhost:8080

docker build -t posthog-proxy . && docker run -p 8080:8080 posthog-proxy
