How the work actually flows

It branches. Exactly one path is taken.

The problem it solves

When a pod gets stuck, a service stops responding, or containers start restarting in a loop, you often don't find out until a customer complains. Checking dashboards all day just to catch problems early isn't a realistic use of your time.

Who it fits

DevOps and IT teams running Kubernetes who need to catch infrastructure problems before customers do.

How it works

  1. The system checks Prometheus metrics on a schedule
  2. It detects pods stuck pending, containers not ready, and restart spikes
  3. It compares current service endpoints against the last check for changes
  4. A clear alert with pod, namespace, and service details is posted to Slack
What you get

Outages you hear about before customers do

You get an instant Slack alert the moment pods or services in your Kubernetes cluster start failing, before customers notice anything is wrong.

What you get

Real-time Slack alerts flagging Kubernetes pod, container, and service issues as they happen.

What you need

A Prometheus instance with kube-state-metrics, and a Slack workspace.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.
