Pred8tor: Your Go-To Tool for Kubernetes Object Expiry

Managing a Kubernetes cluster can be an arduous task, especially when it comes to keeping your environment clean and clutter-free. Over time, obsolete Kubernetes objects like pods, services, and deployments accumulate, which can lead to inefficiencies and potential performance issues. Pred8tor, an innovative open-source tool, addresses this challenge by automating the cleanup of expired Kubernetes objects, ensuring your cluster remains tidy and efficient.

What is Pred8tor?

Pred8tor is a Python-based open-source tool designed to maintain clean Kubernetes environments by automatically identifying and removing expired objects. By leveraging an “expiration_time” label, Pred8tor simplifies the process of resource management within your Kubernetes cluster.

How Does Pred8tor Work?

Using Pred8tor is straightforward. You tag Kubernetes objects with an expiration time label, specifying when they should be terminated. Here’s a simple example:

bashCopy codekubectl label pods ubuntu expiration_time=1706255118

This command sets the expiration time for the labeled pod to the specified epoch time, which translates to Saturday, January 27, 2024, 11:29:50 AM. When this time arrives, Pred8tor will automatically terminate the specified pod object.

Objects Supported

Currently, Pred8tor supports the termination of various Kubernetes objects, including:

  • Deployments
  • Pods
  • Namespaces
  • Services

More object types will be supported in future updates, making Pred8tor an even more versatile tool for Kubernetes management.

Key Features

  1. Automated Cleanup
    • Expiration-Based Termination: Pred8tor operates based on an “expiration_time” label, ensuring objects are removed precisely when they are no longer needed.
    • Continuous Monitoring: Once set up, Pred8tor runs in the background, constantly monitoring for objects that have reached their expiration time.
  2. Simple Integration
    • Ease of Use: Integrating Pred8tor into your Kubernetes workflow is simple. By adding expiration labels to your objects, you automate the cleanup process with minimal effort.
    • Safe Deletion: Pred8tor ensures the safe and timely deletion of expired objects, helping you maintain a clean and efficient cluster environment.


Installing Pred8tor is quick and easy. Follow these steps to get started:

  1. Clone the Repository bashCopy codegit clone
  2. Apply the Deployment Configuration bashCopy codekubectl apply -f deployment/pred8tor_deployment.yaml

With these steps, Pred8tor will be up and running, ready to start cleaning up your Kubernetes objects.
