Cloudrun Tailscale Reverse Proxy

Setup

1. Create a ephemeral key in Tailscale
2. Set TAILSCALE_AUTHKEY in your Cloud Run environment variables
3. Set TARGET_URL in your Cloud Run environment variables to the your device on your network.

Due to how ephemeral keys work, they do not allocate an IPv4, so you must hit the IPv6 address of the device. Thankfully Magic DNS makes this easy with the AAAA record. So you can set the TARGET_URL to something like: http://[device].[namespace].io.beta.tailscale.net:8080

Usage

$ mage -l
Targets:
  build*    handles building the app
  clean     handles cleaning the project up
  deploy    handles deploying to cloud run
