Caddy Reverse Proxy Config

[pomology]

Is there a Caddy reverse-proxy template available? It would be extremely helpful to have one. Thank you!

[CrimsonFez]

there isn't. However you can look in infrastructure_files/getting-started-with-zitadel.sh for an example.

I've modified it for my own usage:

netbird.example.net {
	reverse_proxy /* netbird-dash:80
	reverse_proxy /signalexchange.SignalExchange/* h2c://netbird-signal
	reverse_proxy /api/* netbird-mgmt
	reverse_proxy /management.ManagementService/* h2c://netbird-mgmt
	header * {
		Strict-Transport-Security "max-age=3600; includeSubDomains; preload"
		X-Content-Type-Options "nosniff"
		X-Frame-Options "DENY"
		X-XSS-Protection "1; mode=block"
		-Server
		Referrer-Policy strict-origin-when-cross-origin
	}
}

Thank you so much for pointing out that helpful source!

So then, the docker-compose.yml file would need this section added under "services":

  caddy:
    image: caddy
    restart: unless-stopped
    networks: [ netbird ]
    ports:
      - '443:443'
      - '80:80'
    volumes:
      - netbird_caddy_data:/data
      - ./Caddyfile:/etc/caddy/Caddyfile

And under "volumes" add:

netbird_caddy_data:

Besides that, are there any other config changes you made for caddy to work?

Thank you so much for your help! I really appreciate your input.

Is this conf working with caddy ?

@sfnemis As far as the Compose file, yes that works with Caddy. I've pasted my sanitized Compose file below. I also pasted the CaddyFile config I'm using. Everything is working with this setup, except that all my peers are getting an identical private IP set as their "Public IP" (like 10.89.1.53). I'm not sure why, and I have an open bug submission here on it. Anyway, here's what I've got so far! I'll post again when we get the IP issue figured out.

Here is my Caddyfile, from NetBird's default configs:

{
  debug
	servers :80,:443 {
    protocols h1 h2c
  }
}

(security_headers) {
    header * {
     
        Strict-Transport-Security "max-age=3600; includeSubDomains; preload"
        X-Content-Type-Options "nosniff"
        X-Frame-Options "DENY"
        X-XSS-Protection "1; mode=block"
        -Server
        Referrer-Policy strict-origin-when-cross-origin
    }
}

:80, REDACTED.REDACTED.com:443 {
    import security_headers
    reverse_proxy /signalexchange.SignalExchange/* h2c://signal:10000
    reverse_proxy /api/* management:80
    reverse_proxy /management.ManagementService/* h2c://management:80
    reverse_proxy /* dashboard:80
}

And here's my compose.yml, again just built on NetBird's default:

version: "3"

Maybe it helps somebody
Using Azure AD as IdP and the Safari Browser i got the error
AADSTS50011: The reply url specified in the request does not match the reply
because Safari calles /auth using http.
I added a rule catching all http requests and redirecting /auth to https manually and
also needed to do the same for the dashboard otherwise the screen would just be blank.

http://<YOUR_DOMAIN> {
	@http protocol http

	handle_path /auth {
		redir @http https://{host}{uri} html
	}

	handle_path / {
		redir @http https://{host}{uri}
	}
}

:80, :443 {
	import security_headers
	reverse_proxy /signalexchange.SignalExchange/* h2c://signal:10000
	reverse_proxy /api/* management:80
	reverse_proxy /management.ManagementService/* h2c://management:80
	reverse_proxy /* dashboard:80
