# Deploy and Host Karma Alertmanager Dashboard on Railway

Group, inspect and silence alerts from your existing Alertmanager.

**Draft status:** Configuration and upstream documentation reviewed. Container startup, Railway application workflows, restart behavior, backup restoration and costs remain unverified.

## About Hosting

Group, inspect and silence alerts from your existing Alertmanager.

| Service | Role | Persistent path |
| --- | --- | --- |
| `app` | Private application or dependency | `None` |
| `karma` | Public owner gateway | `None` |

## Why Deploy

Run this application in your own Railway project, with explicit configuration and storage under your control.

## Common Use Cases

- Group, inspect and silence alerts from your existing Alertmanager.

## Dependencies for Karma Alertmanager Dashboard

### Deployment Dependencies

The application images are pinned by registry digest. Database services, when included, stay on the private network. One replica is supported for each volume-backed service.

Supply these required settings before deployment: `app.ALERTMANAGER_URI`.

## First use

Open the `karma` service's HTTPS domain. Sign in to the owner gateway with username `admin` and its generated `ACCESS_PASSWORD`. Complete the application's own setup afterward.

API calls must also send `X-Template-Key` with that owner password. The gateway forwards native Bearer tokens, strips Basic Authorization, and limits requests to 32 MiB. Browser sessions receive a secure owner cookie. Native clients, webhooks and public sharing require specific compatibility checks before use. Gateway `/healthz` only checks the proxy, not application readiness.

Set ALERTMANAGER_URI to a reachable Alertmanager, including credentials if it uses Basic auth. The dashboard is protected by the owner gateway; requests that create silences are proxied server-side.

## Scope and limitations

- A reachable Alertmanager is required and is not provisioned by this template.
- Alert and silence data remains in Alertmanager; Karma does not need a volume.
- The owner gateway is a shared administrator boundary, not per-user role management.

## Acceptance checks before use

- Load a known alert from Alertmanager and create a short test silence.
- Confirm the browser does not receive an upstream URI containing credentials.
- Confirm generated credentials are distinct on a second fresh deployment.
- Back up every listed persistent path and database, then restore into a separate test project.
- Measure Railway usage with representative data and workload before estimating operating costs.

## Backups and upgrades

Back up databases, file volumes, encryption keys and configuration together. Keep a copy outside the running project. Review upstream migration notes before changing a digest; rollback can require restoring a compatible database and files, not just selecting an older image.

## Sources and selection evidence

- [Upstream documentation](https://github.com/prymitive/karma/blob/v0.133/docs/CONFIGURATION.md): Single-server ALERTMANAGER_URI and ALERTMANAGER_PROXY environment configuration; proxy prevents upstream URI credentials leaking to clients.
- [Upstream documentation](https://github.com/prymitive/karma/blob/v0.133/Dockerfile): Official distroless image and default port 8080.
- [Upstream project](https://github.com/prymitive/karma)

Product and alias searches found no matching public Railway listing during this research. This is a bounded search result; private, unindexed or differently named listings may exist. It is not evidence of demand or revenue.

Upstream software retains its own license and edition restrictions. This deployment draft does not imply upstream endorsement.
