Claude e3c23c263b relay: deploy templates expose UDP, mgmt threads transport hints
Two follow-ups to the WebTransport/ALPN-mux landing:

Deployment templates publish UDP alongside TCP for the relay so the
single ALPN-multiplexed socket can serve raw QUIC and WebTransport
clients on the same port as the existing WebSocket transport.

- docker-compose.yml.tmpl: adds the matching `/udp` mapping; the relay
  was already binding both stacks, the host port just wasn't published.
- docker-compose.yml.tmpl.traefik: WebTransport is the awkward case —
  Traefik can't proxy WT sessions, so the relay container now publishes
  UDP/443 directly and obtains its own Let's Encrypt cert (separate
  volume), while the TCP /relay route stays behind Traefik unchanged so
  WS-only clients keep working.

Management server learned to advertise per-relay transport hints:

- Config gains an optional `Endpoints []{URL, Transports}` block on the
  Relay section, mirrored to clients as RelayConfig.endpoints.
- `Addresses` is still emitted as RelayConfig.urls so older agents keep
  working unchanged.
- A single BuildRelayConfigProto helper is the only place that builds
  the proto, called from both toNetbirdConfig and the token push paths.

The GeoDNS case is operator-asserted, not probed: a single URL fans out
to several physical relays, and the Transports list must already be the
intersection of what every backend supports. Documented on the config
struct — if any backend behind a hostname can't speak h3, the operator
drops "wt" from that hostname's list and no client tries it there.

netbird Management Server

netbird management server will control and synchronize peers configuration within your Netbird account and network.

Command Options

The CLI accepts the command management with the following options:

start Netbird Management Server

Usage:
  netbird-mgmt management [flags]

Flags:
      --cert-file string            Location of your SSL certificate. Can be used when you have an existing certificate and don't want a new certificate be generated automatically. If letsencrypt-domain is specified this property has no effect
      --cert-key string             Location of your SSL certificate private key. Can be used when you have an existing certificate and don't want a new certificate be generated automatically. If letsencrypt-domain is specified this property has no effect
      --datadir string              server data directory location
  -h, --help                        help for management
      --letsencrypt-domain string   a domain to issue Let's Encrypt certificate for. Enables TLS using Let's Encrypt. Will fetch and renew certificate, and run the server with TLS
      --port int                    server port to listen on (default 33073)

Global Flags:
      --config string      Netbird config file location to write new config to (default "/etc/netbird")
      --log-file string    sets Netbird log path. If console is specified the the log will be output to stdout (default "/var/log/netbird/management.log")
      --log-level string    (default "info")

Run Management service (Docker)

You can run service in 2 modes - with TLS or without (not recommended).

Run with TLS (Let's Encrypt).

By specifying the --letsencrypt-domain the daemon will handle SSL certificate request and configuration.

In the following example 33073 is the management service default port, and 443 will be used as port for Let's Encrypt challenge and HTTP API.

The server where you are running a container has to have a public IP (for Let's Encrypt certificate challenge).

Replace with your server's public domain (e.g. mydomain.com or subdomain sub.mydomain.com).

# create a volume
docker volume create netbird-mgmt
# run the docker container
docker run -d --name netbird-management \
-p 33073:33073  \
-p 443:443  \
-v netbird-mgmt:/var/lib/netbird  \
-v ./config.json:/etc/netbird/config.json  \
netbirdio/management:latest \
--letsencrypt-domain <YOUR-DOMAIN>

An example of config.json can be found here management.json

Trigger Let's encrypt certificate generation:

curl https://<YOUR-DOMAIN>

The certificate will be persisted in the datadir/letsencrypt/ folder (e.g. /var/lib/netbird/letsencrypt/) inside the container.

Make sure that the datadir is mapped to some folder on a host machine. In case you used the volume command, you can run the following to retrieve the Mountpoint:

docker volume inspect netbird-mgmt
[
    {
        "CreatedAt": "2021-07-25T20:45:28Z",
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/mgmt/_data",
        "Name": "netbird-mgmt",
        "Options": {},
        "Scope": "local"
    }
]

Consequent restarts of the container will pick up previously generated certificate so there is no need to trigger certificate generation with the curl command on every restart.

Run without TLS.

# create a volume
docker volume create netbird-mgmt
# run the docker container
docker run -d --name netbird-management \
-p 33073:33073  \
-v netbird-mgmt:/var/lib/netbird  \
-v ./config.json:/etc/netbird/config.json  \
netbirdio/management:latest

Debug tag

We also publish a docker image with the debug tag which has the log-level set to default, plus it uses the gcr.io/distroless/base:debug image that can be used with docker exec in order to run some commands in the Management container.

shell $ docker run -d --name netbird-management-debug \
-p 33073:33073  \
-v netbird-mgmt:/var/lib/netbird  \
-v ./config.json:/etc/netbird/config.json  \
netbirdio/management:debug-latest

shell $ docker exec -ti netbird-management-debug /bin/sh
container-shell $
