# Running headscale behind a reverse proxy
|
|
|
|
Running headscale behind a reverse proxy is useful when running multiple applications on the same server, and you want to reuse the same external IP and port - usually tcp/443 for HTTPS.
|
|
|
|
### WebSockets
|
|
|
|
The reverse proxy MUST be configured to support WebSockets, as it is needed for clients running Tailscale v1.30+.
|
|
|
|
WebSockets support is required when using the headscale embedded DERP server. In this case, you will also need to expose the UDP port used for STUN (by default, udp/3478). Please check our [config-example.yaml](https://github.com/juanfont/headscale/blob/main/config-example.yaml).
|
|
|
|
### TLS
|
|
|
|
Headscale can be configured not to use TLS, leaving it to the reverse proxy to handle. Add the following configuration values to your headscale config file.
|
|
|
|
```yaml
|
|
server_url: https://<YOUR_SERVER_NAME> # This should be the FQDN at which headscale will be served
|
|
listen_addr: 0.0.0.0:8080
|
|
metrics_listen_addr: 0.0.0.0:9090
|
|
tls_cert_path: ""
|
|
tls_key_path: ""
|
|
```
|
|
|
|
## nginx
|
|
|
|
The following example configuration can be used in your nginx setup, substituting values as necessary. `<IP:PORT>` should be the IP address and port where headscale is running. In most cases, this will be `http://localhost:8080`.
|
|
|
|
```Nginx
|
|
map $http_upgrade $connection_upgrade {
|
|
default keep-alive;
|
|
'websocket' upgrade;
|
|
'' close;
|
|
}
|
|
|
|
server {
|
|
listen 80;
|
|
listen [::]:80;
|
|
|
|
listen 443 ssl http2;
|
|
listen [::]:443 ssl http2;
|
|
|
|
server_name <YOUR_SERVER_NAME>;
|
|
|
|
ssl_certificate <PATH_TO_CERT>;
|
|
ssl_certificate_key <PATH_CERT_KEY>;
|
|
ssl_protocols TLSv1.2 TLSv1.3;
|
|
|
|
location / {
|
|
proxy_pass http://<IP:PORT>;
|
|
proxy_http_version 1.1;
|
|
proxy_set_header Upgrade $http_upgrade;
|
|
proxy_set_header Connection $connection_upgrade;
|
|
proxy_set_header Host $server_name;
|
|
proxy_redirect http:// https://;
|
|
proxy_buffering off;
|
|
proxy_set_header X-Real-IP $remote_addr;
|
|
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
|
proxy_set_header X-Forwarded-Proto $http_x_forwarded_proto;
|
|
add_header Strict-Transport-Security "max-age=15552000; includeSubDomains" always;
|
|
}
|
|
}
|
|
```
|
|
|
|
## istio/envoy
|
|
|
|
If you using [Istio](https://istio.io/) ingressgateway or [Envoy](https://www.envoyproxy.io/) as reverse proxy, there are some tips for you. If not set, you may see some debug log in proxy as below:
|
|
|
|
```log
|
|
Sending local reply with details upgrade_failed
|
|
```
|
|
|
|
### Envoy
|
|
|
|
You need add a new upgrade_type named `tailscale-control-protocol`. [see detail](https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/network/http_connection_manager/v3/http_connection_manager.proto#extensions-filters-network-http-connection-manager-v3-httpconnectionmanager-upgradeconfig)
|
|
|
|
### Istio
|
|
|
|
Same as envoy, we can use `EnvoyFilter` to add upgrade_type.
|
|
|
|
```yaml
|
|
apiVersion: networking.istio.io/v1alpha3
|
|
kind: EnvoyFilter
|
|
metadata:
|
|
name: headscale-behind-istio-ingress
|
|
namespace: istio-system
|
|
spec:
|
|
configPatches:
|
|
- applyTo: NETWORK_FILTER
|
|
match:
|
|
listener:
|
|
filterChain:
|
|
filter:
|
|
name: envoy.filters.network.http_connection_manager
|
|
patch:
|
|
operation: MERGE
|
|
value:
|
|
typed_config:
|
|
"@type": type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager
|
|
upgrade_configs:
|
|
- upgrade_type: tailscale-control-protocol
|
|
```
|
|
|
|
## Caddy
|
|
|
|
The following Caddyfile is all that is necessary to use Caddy as a reverse proxy for headscale, in combination with the `config.yaml` specifications above to disable headscale's built in TLS. Replace values as necessary - `<YOUR_SERVER_NAME>` should be the FQDN at which headscale will be served, and `<IP:PORT>` should be the IP address and port where headscale is running. In most cases, this will be `localhost:8080`.
|
|
|
|
```
|
|
<YOUR_SERVER_NAME> {
|
|
reverse_proxy <IP:PORT>
|
|
}
|
|
```
|
|
|
|
Caddy v2 will [automatically](https://caddyserver.com/docs/automatic-https) provision a certficate for your domain/subdomain, force HTTPS, and proxy websockets - no further configuration is necessary.
|
|
|
|
For a slightly more complex configuration which utilizes Docker containers to manage Caddy, Headscale, and Headscale-UI, [Guru Computing's guide](https://blog.gurucomputing.com.au/smart-vpns-with-headscale/) is an excellent reference.
|
|
|
|
## Apache
|
|
|
|
The following minimal Apache config will proxy traffic to the Headscale instance on `<IP:PORT>`. Note that `upgrade=any` is required as a parameter for `ProxyPass` so that WebSockets traffic whose `Upgrade` header value is not equal to `WebSocket` (i. e. Tailscale Control Protocol) is forwarded correctly. See the [Apache docs](https://httpd.apache.org/docs/2.4/mod/mod_proxy_wstunnel.html) for more information on this.

<VirtualHost *:443>
