k8s-overcommit-operator: Smart Resource Management for Kubernetes 🚀

Overview

The k8s-overcommit-operator is a Kubernetes operator that intelligently manages resource overcommit on pod resource requests. This operator allows you to optimize your cluster's resource usage by overcommitting resources based on historical data and usage patterns. It ensures that your applications run smoothly while maximizing resource efficiency.

Features

• Intelligent Overcommit Management: Automatically adjusts resource requests based on actual usage.
• Historical Data Analysis: Leverages historical data to make informed decisions about resource allocation.
• Customizable Policies: Define overcommit policies that suit your specific needs.
• Seamless Integration: Works with existing Kubernetes and OpenShift environments.

Getting Started

To get started with the k8s-overcommit-operator, you need to download the latest release. Visit the Releases section to find the appropriate version for your environment.

Prerequisites

• A running Kubernetes or OpenShift cluster.
• kubectl installed and configured to communicate with your cluster.
• Operator SDK installed for building and managing operators.

Installation

1. Download the Operator: Visit the Releases section to download the latest version.

2. Install the Operator: Execute the downloaded file using the following command:

   ./k8s-overcommit-operator install

3. Verify Installation: Check if the operator is running:

   kubectl get pods -n k8s-overcommit-operator

Usage

Configuring Overcommit Policies

After installation, you can configure overcommit policies to suit your workload requirements. Here’s how to create a policy:

1. Create a Policy YAML File:

   apiVersion: overcommit.k8s.io/v1
   kind: OvercommitPolicy
   metadata:
     name: example-policy
     namespace: k8s-overcommit-operator
   spec:
     cpuOvercommitRatio: 2.0
     memoryOvercommitRatio: 1.5

2. Apply the Policy:

   kubectl apply -f policy.yaml

3. Monitor the Operator: Use the following command to check the status of the operator:

   kubectl logs -f deployment/k8s-overcommit-operator -n k8s-overcommit-operator

Custom Resource Definitions (CRDs)

The operator uses CRDs to manage overcommit policies. Here’s a list of CRDs used by the k8s-overcommit-operator:

• OvercommitPolicy: Defines the overcommit policies.
• ResourceUsage: Tracks the resource usage of pods.

Monitoring and Metrics

The operator provides metrics that you can scrape using Prometheus. To enable metrics, ensure that your operator deployment includes the metrics endpoint configuration.

spec:
  template:
    spec:
      containers:
      - name: k8s-overcommit-operator
        ports:
        - containerPort: 8080
          name: metrics
