Environment Configuration

All settings are configured in backend/.env. Copy backend/.env.example to backend/.env and fill in the values for the providers you want to use. The backend must be restarted after any changes to .env.


Cloudflare

Variable Required Description
CLOUDFLARE_API_TOKEN Yes API token with Zone:Read and DNS:Edit permissions

Create a token at dash.cloudflare.com → My Profile → API Tokens → Create Token. See API-ACCESS.md for the required permissions.


Loopia

Variable Required Description
LOOPIA_USER Yes API username in the format youruser@loopiaapi
LOOPIA_PASSWORD Yes API user password

Create an API user at customerzone.loopia.se → My Account → API Users. See API-ACCESS.md for the required method groups.


Pi-hole

Variable Required Description
PIHOLE_URL Yes Base URL of the Pi-hole instance, e.g. http://192.168.1.x
PIHOLE_PASSWORD Yes Pi-hole web interface password

Requires Pi-hole v6. Only A, AAAA, and CNAME records are supported. TTL is not configurable via the Pi-hole API.


Azure DNS

Variable Required Description
AZURE_TENANT_ID Yes Azure AD tenant ID
AZURE_CLIENT_ID Yes Service principal application (client) ID
AZURE_CLIENT_SECRET Yes Service principal client secret
AZURE_SUBSCRIPTION_ID Yes Azure subscription ID containing the DNS zones

The service principal requires the DNS Zone Contributor role on the subscription or resource group. See API-ACCESS.md for setup instructions.


cPanel

Variable Required Description
CPANEL_URL Yes cPanel URL including port, e.g. https://hostname:2083
CPANEL_USERNAME Yes cPanel account username
CPANEL_API_TOKEN Yes API token created in cPanel → Security → Manage API Tokens
CPANEL_INSECURE No Set to true to disable SSL certificate verification. Use when cPanel uses a self-signed certificate. Defaults to false.

The cPanel account must own the domains you want to manage. Uses the cPanel UAPI and API 2 (ZoneEdit module). See API-ACCESS.md for setup instructions.


Authentik SSO

Single sign-on via Authentik (optional). When configured, a Sign in with Authentik button appears on the login page alongside the regular username/password form. Users who sign in via SSO for the first time are automatically created as local accounts.

Variable Required Description
AUTHENTIK_URL Yes Issuer URL of your Authentik application, e.g. https://auth.example.com/application/o/sloth-manager
AUTHENTIK_CLIENT_ID Yes Client ID from the Authentik OAuth2/OIDC Provider
AUTHENTIK_CLIENT_SECRET Yes Client secret from the Authentik OAuth2/OIDC Provider

Setup steps in Authentik:

  1. Go to Applications → Providers → Create and choose OAuth2/OpenID Provider.
  2. Set Client type to Confidential.
  3. Under Redirect URIs, add your Sloth Manager URL with a trailing slash, e.g. https://slothmgmt.example.com/. The trailing slash is required — Authentik does exact-match on redirect URIs.
  4. Copy the Client ID and Client Secret into your .env.
  5. Go to Applications → Applications → Create, select the provider, and note the Slug.
  6. Set AUTHENTIK_URL to https://your-authentik-host/application/o/<slug>.

SSO is disabled (and the button is hidden) when any of the three AUTHENTIK_* variables are missing.


phpIPAM

Import IP addresses and devices from a self-hosted phpIPAM instance (optional). When configured, the IPAM page gains a Sync External button and shows a phpIPAM source badge on synced entries. Addresses can be edited or deleted with write-back to phpIPAM.

Variable Required Description
PHPIPAM_URL Yes Base URL of your phpIPAM instance, e.g. https://ipam.example.com
PHPIPAM_APP_ID Yes API application ID created in phpIPAM → Administration → API
PHPIPAM_TOKEN Yes Static app token (token-based auth, no username/password needed)

Setup steps in phpIPAM:

  1. Go to Administration → phpIPAM Settings and enable the REST API.
  2. Go to Administration → API and click + Create API key.
  3. Set App identifier to any slug (e.g. sloth-manager), App permissions to Read/Write, and App security to SSL with App code token.
  4. Copy the App code — this is your PHPIPAM_TOKEN.
  5. Set PHPIPAM_APP_ID to the same slug you chose as the App identifier.

phpIPAM integration is disabled when any of the three PHPIPAM_* variables are missing.


Tailscale

Import devices from a Tailscale tailnet (optional). When configured, the IPAM page shows devices with their Tailscale IPs. Devices can be authorized/de-authorized or removed from the tailnet directly from Sloth Manager.

Variable Required Description
TAILSCALE_API_KEY Yes API key generated at tailscale.com/settings/keys
TAILSCALE_TAILNET Yes Tailnet name, e.g. yourorg.github — use - to target your default tailnet

Setup steps:

  1. Go to tailscale.com → Settings → Keys → Generate access token.
  2. Grant the token Devices: Read and Devices: Write (write is needed for authorize and delete actions).
  3. Set TAILSCALE_TAILNET to your tailnet name (visible in the Admin console URL: login.tailscale.com/admin/machines/<tailnet>), or use - for the default.

Tailscale integration is disabled when either variable is missing.


Authentication

Variable Required Description
JWT_SECRET Yes A long random string used to sign login tokens. Generate one with: node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"
JWT_EXPIRES_IN No How long login sessions last. Defaults to 24h. Accepts values like 12h, 7d.

General

PORT No Port the backend listens on. Defaults to 3001.
DB_PATH No Path to the DNS record cache file. Defaults to backend/dns-cache.json.
