Keenrig

Self-host Zipkin on a VPS in one command

A developer tool: follows a request across several services to find where it slows down.

Install it on your server

Cloud

The easiest way is through the Console: connect a server, then install the app from the catalog.

  1. Sign in to the Keenrig Console

  2. Add a server and run the install command the Console gives you on your VPS

  3. Go to Catalog, pick this app and press Install

Open the ConsoleInstall Keenrig

Zipkin collects and displays distributed traces: how many services a request passed through, where it spent the most time, and which hop threw the error. With a single app, logs are enough; the moment two apps call each other, "where is it slow" stops being answerable by reading each side’s log.

What you would use it for

  • Find the slow hop in a call chain across several services, instead of guessing by comparing timestamps between log files.
  • Stand up a trial environment for an application that already ships tracing libraries, without preparing any storage first.
  • Learn or demonstrate distributed tracing: post a few traces by hand to port 9411 and watch them appear on the dependency graph.

What Keenrig handles for you

  • Wants 512 MB of memory — the heaviest entry in the current catalogue, because traces live in process memory.
  • Health checked at its own `/health` path, so the platform never mistakes a slow-loading UI for a dead app.
  • Pinned by digest `sha256:d17e856d…` rather than by the `3` tag: a redeploy next month runs exactly today’s image.

What it does not do. The default configuration keeps traces IN MEMORY. Redeploy, restart, or replace the container and every previous trace is gone — a deliberate choice so this entry needs no disk, not an oversight. If you need traces to survive for days, Zipkin requires external storage (Cassandra, Elasticsearch, MySQL), and this catalogue entry does not set that up for you.
