Simple Dex setup to authenticate with Tailscale.
This means you can login to services that support OIDC authentication using only your Tailscale IP!
Note: You can (and should) try Tailscale's tsidp instead if you only need auth via Tailscale!
Here is an example video of authenticating to Cloudflare Access with Tailscale:
Fill in the values in dex.env and tailscale.env using dex.env.example and tailscale.env.example respectively.
The default dex.yaml configuration includes Cloudflare Access as a client, but you can update this if you want :)
Then just run docker compose up and you're done!
