Full Description

Autopilot Pattern Prometheus

This repo is an extension of the official Docker image, designed to be self-operating according to the Autopilot Pattern. This application demonstrates support for configuring Prometheus to be used as a metrics collector for applications using the ContainerPilot telemetry endpoint.

Using Prometheus with ContainerPilot

The Dockerfile provided uses ContainerPilot in the Prometheus container to populate (and keep updated) the Prometheus configuration file with a list of targets.

For targets, ContainerPilot supports a Prometheus-compatible telemetry endpoint. If a telemetry option is provided, ContainerPilot will expose a Prometheus HTTP client interface that can be used to scrape performance telemetry. The telemetry interface is advertised as a service to the discovery service similar to services configured via the ContainerPilot services block. Each sensor for the telemetry service will run periodically and record values in the Prometheus client library. A Prometheus server can then make HTTP requests to the telemetry endpoint.

Run it!

  1. Get a Joyent account and add your SSH key.
  2. Install the Docker Toolbox (including docker and docker-compose) on your laptop or other environment, as well as the Joyent Triton CLI (triton replaces our old sdc-* CLI tools).
  3. Configure Docker and Docker Compose for use with Joyent.

Check that everything is configured correctly by running ./ This will check that your environment is setup correctly and will create an _env file that includes injecting an environment variable for the Consul hostname into the Prometheus container so we can take advantage of Triton Container Name Service (CNS).

$ docker-compose up -d

Creating prometheus_consul_1

$ docker-compose ps
Name                         Command           State    Ports
prometheus_consul_1          /bin/start -server    Up   53/tcp, 53/udp,
                             -bootst ...                8300/tcp, 8301/tcp,
                                                        8301/udp, 8302/tcp,
                                                        8302/udp, 8400/tcp,
prometheus_prometheus_1      /bin/containerpilot   Up>9090/tcp

Once you have Prometheus running you should be able to check its current status by making an HTTP request to its own telemetry endpoint:

# pipe it to less because there's a lot of data!
$ curl "http://$(triton ip prometheus_prometheus_1):9090/telemetry" | less
