Description

Adds a maintenance guide for moving a self-hosted NetBird deployment to a new hostname. This comes up regularly in the community (most recently in this r/netbird thread), where users piece the steps together from the config files reference and trial and error.

The guide targets the current getting-started.sh layout (combined netbird-server container, config.yaml, dashboard.env) and covers both the server side and the part people usually get stuck on: existing peers keep the old management URL in their local config and have to be pointed at the new one.

Running example throughout: netbird.example.com to vpn.example.com.

Key points verified against the netbird source:

  • The hostname is written to exactly three generated files: Traefik Host() labels in docker-compose.yml, exposedAddress / auth.issuer / dashboardRedirectURIs in config.yaml, and the endpoint and authority variables in dashboard.env.
  • The combined server derives the relay and signal addresses from exposedAddress, so a stale value leaves peers connected to management but unable to reach each other.
  • Peers are identified by WireGuard public key, so netbird down followed by netbird up --management-url <new> reconnects the same peer with the same IP. No re-registration or new setup key.
  • Docker peers pick up NB_MANAGEMENT_URL on recreate: the entrypoint runs netbird up, env vars populate flags, and the daemon updates the stored profile when the URL differs.
  • Peer DNS names do not change. The DNS suffix comes from the persisted account domain (netbird.selfhosted by default), not from the server hostname.
  • No Traefik command: changes are needed; the Let's Encrypt resolver requests a certificate for whatever host the router rules name.

Also covers external reverse proxy setups (the printed templates are copies, the live proxy config must change), external identity providers (redirect URIs on the provider side), the NetBird Proxy service domain, desktop profiles, mobile, MDM-managed fleets, and an optional Traefik bridge that keeps the old hostname answering while peers are migrated.

Changes

  • New: src/pages/selfhosted/maintenance/change-domain.mdx, served at /selfhosted/maintenance/change-domain.
  • Nav: added "Change Domain" under Self-Host NetBird → Maintenance, after Upgrade, in src/components/NavigationDocs.jsx.

- Shell access to the host and the directory where you ran `getting-started.sh`. It holds `docker-compose.yml`, `config.yaml`, and `dashboard.env`.
- Control of DNS for the new name, and ports 80 and 443 still reachable on the host so Traefik can complete the Let's Encrypt challenge.
- A maintenance window. Between recreating the server and updating a peer, that peer cannot reach the management server. Tunnels that are already established generally keep running, but no new connections can be negotiated until the peer is updated.

Qualify peer downtime when the routing bridge remains enabled.

Without the optional bridge, these statements are correct. With the bridge from Step 4, peers using netbird.example.com can continue to sync. Add “unless the old hostname remains in the router rules” to both statements.

### If you use an external identity provider

If you replaced the embedded identity provider with Zitadel, Authentik, Keycloak, or another OIDC provider, the `issuer` and `AUTH_AUTHORITY` values point at that provider and stay as they are. What does change is on the provider's side: update the NetBird application's redirect URIs to `https://vpn.example.com/nb-auth` and `https://vpn.example.com/nb-silent-auth`, plus any post-logout URI you configured. The CLI redirect `http://localhost:53000/` is unaffected. See [Identity Providers](/selfhosted/identity-providers) for where each provider keeps these.

Separate standalone IdP guidance from the combined-container workflow.

getting-started.sh creates a combined netbird-server deployment with embedded Dex. Current external providers are added alongside Dex, so issuer and AUTH_AUTHORITY remain the deployment URL. Standalone configurations use setup.env and different callback paths, such as /auth and /silent-auth. Mark this section as standalone/legacy and identify its file layout, or remove it from this guide. Make the Step 4 OIDC check conditional because its hard-coded embedded issuer is not valid for standalone deployments.

Comment on lines +34 to +38

Nothing in the database depends on the hostname. Accounts, users, peers, groups, policies, routes, and setup keys all carry over untouched. On v0.67.0 and later, peer DNS names also stay the same: the peer DNS suffix is the account's persisted DNS domain (`netbird.selfhosted` by default), not the current server hostname.

<Note>
This guide is for renaming the one public hostname of a deployment. If you only want the server reachable under a second name (for example an internal one) while keeping the current domain, this is the wrong tool: `exposedAddress` and the identity provider issuer can hold only one value. Keep the domain and put the second name in front with your own reverse proxy instead.

Clarify the maintenance-window boundary

The routing bridge keeps old-host peers connected after the stack restarts, but docker compose down still stops Traefik and temporarily makes both hostnames unavailable. State that the bridge prevents the post-restart peer outage, not the brief interruption during stack recreation.

### Docker peers

The container image runs `netbird up` on start and reads its initial settings from `NB_*` environment variables. Keep the old-host routing bridge from step 4 active while updating Docker peers. An existing profile in `/var/lib/netbird` can take precedence over a changed `NB_MANAGEMENT_URL`; if the old hostname no longer routes, the entrypoint can restart-loop before you can run `docker compose exec`.

Remove the persisted-profile restart-loop warning.

upFunc calls SetFlagsFromEnvVars before setupConfig, and config.apply replaces an existing ManagementURL when a value is supplied. Therefore NB_MANAGEMENT_URL updates the persisted profile instead of letting the old URL take precedence. The netbirdio/netbird:latest procedure does not require the old-host bridge or restart-loop recovery.
