OpenMeter Pod Runtime Watcher

A simple program to watch pods in a Kubernetes cluster and report their lifetime to OpenMeter.

This application is meant to be run using Helm, but you can test it directly on your machine using the binary build.

Getting started

Prerequisites

1. You have a Kubernetes cluster running
2. You have a running OpenMeter instance (cloud or self-hosted)
3. You have an API key from OpenMeter

Helm (recommended)

See the helm chart README.

Local (testing only)

When running locally, this assumes you have a Kubernetes context already configured.

1. Set your environment variables

   export OPENMETER_TOKEN=om_1234567890abcdef
   export OPENMETER_URL=https://openmeter.cloud  # this is the default and you only need to set when self-hosting
   export NAMESPACE=default # this is the default, change to the namespace you want to watch
   export MONITOR_RATE_SECONDS=5 # this is the default, change to the rate you want to monitor pods (i.e. how often should we check for alive pods)

2. Run the binary

   ./openmeter-pod-runtime-watcher
