Get notified when your containers have new Docker Hub images

Checks your running containers against Docker Hub every few hours and pings you only when a new image is available.

How the work actually flows

It branches. Exactly one path is taken; runs once per each running container.

The problem it solves

Keeping track of which containers are running outdated images means manually comparing what's deployed against what's newly published, over and over. Missing an update can leave you running stale or vulnerable software without realizing it.

Who it fits

DevOps teams and engineers running containerized workloads on Kubernetes who want to stay current without manual checks.

How it works

  1. On a set schedule, the system checks which container images are currently running in your cluster
  2. It compares each one against the latest version available on Docker Hub
  3. If a newer image exists, it flags that container as outdated
  4. A message is sent to Discord alerting you to the new image
What you get

Containers you know are running outdated images

You find out the moment a newer image is available for any container running in your cluster.

What you get

A Discord message alerting your team whenever a running container has a newer image available.

What you need

A Kubernetes cluster, a Docker Hub account, and a Discord server.

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.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
