Self-hosted IPTVnator

User-facing overview with quick start, variables and FAQ: https://4gray.github.io/iptvnator/download/docker/. This file is the reference behind it.

The self-hosted image contains both pieces required for the browser PWA:

• Angular PWA static files served by nginx
• The monorepo web-backend Express app proxied under /api

The historical standalone 4gray/iptvnator-backend image is no longer needed for the default Docker deployment.

PWA Limitations And Playback Troubleshooting

The Docker image runs the browser PWA, not the Electron desktop application. That means:

• EPG/XMLTV panels and multi-EPG views are not available in the self-hosted PWA.
• Playlist metadata is stored in the browser through IndexedDB, and Xtream user data is stored by the PWA data source in localStorage. The PWA does not use the Electron SQLite database or DB worker.
• Docker cannot launch local desktop players or Embedded MPV. If a stream does not play inline in the browser, use the in-app copy URL action and open the stream manually in an external player such as MPV, VLC, or IINA.
• Electron-only features such as the download manager, external-player process control, and remote-control integrations are outside this runtime.

Run With Docker Compose

From the repository root:

docker compose -f docker/docker-compose.yml up --build -d

The ready-to-run compose file is docker-compose.yml. By default the app is available at http://localhost:4333. No additional environment variables, backend repository checkout, or separate backend container are required for the default local deployment.

Build The Image

docker build -t 4gray/iptvnator -f docker/Dockerfile .

The image build runs:

pnpm nx build web --configuration=pwa
pnpm nx build web-backend

Those Nx builds generate platform-independent JS and static assets. In multi-architecture CI builds, the Dockerfile runs this build stage on the native BuildKit builder platform, then copies the generated output into each target runtime image. That avoids running the Angular/Nx build through QEMU when publishing linux/amd64 and linux/arm64 images.

Published Docker Tags

Pull request builds validate the Dockerfile without pushing an image. Docker Hub publishing happens only from trusted repository events. Publishing requires the repository secrets DOCKERHUB_USERNAME and DOCKERHUB_TOKEN; pull request builds and default manual runs do not use those secrets.

Tag pattern	Published from	Use case
latest	master pushes	Default self-hosted image for users who want the newest merged PWA build.
<version>-pwa	master pushes	Latest PWA image for the current package.json version.
<version>-pwa-<sha>	master pushes	Immutable PWA image for a specific merged commit within a version.
sha-<sha>	master pushes	Commit-addressable image, useful for rollback and support diagnostics.
<version> / v<version>	v* release tags	Release image aligned with a repository release tag.
stable	Stable v* release tags	Most recent non-prerelease tagged release image.
manual-<sha>	Manual runs with push	Explicit maintainer-triggered rebuilds outside normal publish events.

Use latest for the simplest self-hosted setup. Pin sha-<sha> or <version>-pwa-<sha> when you need reproducible deployments. Use release tags when you want the Docker image to track a tagged IPTVnator release rather than every merge to master.

Runtime Configuration

The container writes /usr/share/nginx/html/assets/app-config.js on startup. That file sets window.__IPTVNATOR_CONFIG__.BACKEND_URL, which the PWA reads before it creates PwaService.

These variables are supported by the Docker image. The compose file sets the safe local defaults shown below.

Variable	Default	Purpose
BACKEND_URL	/api	Browser-facing backend URL used by the PWA. Keep /api for the bundled nginx proxy.
CLIENT_URL	http://localhost:4333	Allowed browser origin for backend CORS. Use the public URL when hosting behind a reverse proxy. Multiple origins can be comma-separated.
PORT	3000	Internal Express backend port. nginx proxy config is rendered from the template to match it at startup.
IPTVNATOR_PROXY_ALLOW_PRIVATE_NETWORKS	0	Set to 1 or true only for trusted local/LAN deployments that intentionally proxy private network IPTV or mock endpoints.
NODE_EXTRA_CA_CERTS	unset	Optional Node.js CA bundle path for providers using private certificate authorities. Mount the CA file into the container and set this path.

The web backend proxy accepts only http and https provider URLs. The PWA first registers provider URLs through /provider-targets, then uses the returned targetId for playlist, Xtream, and Stalker proxy calls. The backend blocks loopback, private, link-local, and reserved network targets by default so a publicly exposed instance cannot be used as a generic internal-network fetcher. If you enable IPTVNATOR_PROXY_ALLOW_PRIVATE_NETWORKS=1, keep the instance restricted to trusted users.

For providers that use private certificate authorities, keep TLS validation enabled and pass the CA bundle to Node:

services:
    iptvnator:
        volumes:
            - ./ca.pem:/etc/ssl/private/provider-ca.pem:ro
        environment:
            NODE_EXTRA_CA_CERTS: /etc/ssl/private/provider-ca.pem

The entrypoint renders the nginx config from docker/nginx.conf, starts the backend, waits for /health, and only then starts nginx. The nginx config serves the PWA with SPA fallback, avoids caching assets/app-config.js, and proxies /api/* to the internal backend. The Dockerfile and compose file both define a health check against /api/health. If nginx or the backend exits after startup, the entrypoint exits the container so Docker Compose can apply the restart: unless-stopped policy.

IPv6, VPNs, And Connection Fallback

Node races IPv6 and IPv4 addresses when a provider hostname has both ("happy eyeballs"), and its stock per-attempt budget of 250 ms is too short for many VPN and container networks. The classic symptom is a provider that answers wget from inside the container but fails in IPTVnator with Bad Gateway (ETIMEDOUT) — typically behind an IPv4-only VPN namespace such as Gluetun/WireGuard, where the IPv6 route is unreachable and the working IPv4 handshake needs more than 250 ms.

The backend therefore raises the per-attempt connection budget to 2500 ms at startup. This keeps the IPv6→IPv4 fallback fully automatic in both directions. If you pass --network-family-autoselection-attempt-timeout yourself through NODE_OPTIONS, your value wins and the backend leaves it untouched.

If a provider still fails, check the container logs first: outbound provider failures are logged with the target hostname and the underlying Node error codes (ETIMEDOUT, ENETUNREACH, ENOTFOUND, ...), and the same code is returned to the app in the error message. As a last resort you can pin the legacy behavior entirely:

services:
    iptvnator:
        environment:
            # Disables IPv6/IPv4 racing completely; only for networks where
            # IPv6 can never work. Breaks IPv6-only deployments.
            NODE_OPTIONS: '--dns-result-order=ipv4first --no-network-family-autoselection'
