How to Deploy Kener with Docker

Kener is a free, open-source status page and uptime monitor that ships Docker-ready, and the project claims you can deploy it in under two minutes. If you have Docker installed and want a self-hosted status page you can reach in a browser, the flow is: pull the image, run the container with a persistent volume, then open the web UI and start adding monitors. The exact commands and environment variables live in the official Kener documentation, which is the authoritative source for current image names, ports, and configuration options.

What you need before starting

• A host with Docker installed (a small VPS, home server, or local machine all work).
• A free port for the web UI (Kener's docs specify the default; check there rather than assuming).
• A place to persist data, so your monitors, incidents, and settings survive container restarts.
• Optional: a domain and reverse proxy if you want the status page public over HTTPS.

The general deployment flow

1. Get the image

Pull the official Kener image from its registry. The documentation lists the exact image reference — use that rather than a third-party mirror, since tags and registries change.

2. Run the container

Start the container with two things mapped:

• A port mapping so the web UI is reachable from your browser.
• A volume pointing at Kener's data directory, so configuration and history persist.

The documentation provides a ready-to-use docker run command and a Docker Compose example. Compose is the better choice if you also want a database or reverse proxy in the same stack, because you can define the whole setup in one file and bring it up with a single command.

3. Open the status page

Once the container is running, visit the host and port you mapped. You should see the Kener status page — the project's own page shows the familiar "All Systems Operational" banner, built with Svelte and TailwindCSS. From here you configure monitors, incidents, and maintenance windows through the UI.

4. Configure monitoring

After first access, add the services you want to track. Kener supports multiple service types (the project advertises 11), incident management, scheduled maintenance, and subscriber notifications. Set these up in the admin interface rather than in the container config, so changes don't require a restart.

Verify it worked

• The container shows as running (docker ps).
• The web UI loads at your mapped address.
• Data persists: restart the container and confirm your monitors and settings are still there. If they vanish, your volume mapping is wrong.

Common snags

• Port already in use. Change the host-side port in your mapping; the container-side port stays as documented.
• Data lost on restart. Almost always a missing or misconfigured volume. Point it at the directory the docs specify.
• Page unreachable from outside. Check firewall rules and, if you're behind a reverse proxy, that it forwards to the right container port.
• Version drift. Image tags and environment variables change between releases. Treat the official documentation as the source of truth over any tutorial, including this one.

When Docker deployment makes sense

Choose the Docker route if you want a self-hosted status page with minimal setup and you're comfortable managing a container. If you'd rather not run any infrastructure, a hosted status page service removes that burden at the cost of control and, usually, money. Kener's appeal is the combination: open source, Docker-ready, and quick to stand up — but "quick" assumes you already have Docker and a host ready to go.

For the exact commands, image name, ports, and environment variables, go to the Kener documentation linked from kener.ing. That page also carries the GitHub and login links you'll need for the source and any account features.
