IPPR

IPPR is a Go-based web service designed to interact with the Kubernetes API. It provides endpoints to view and dynamically update the CPU and memory resources of a Kubernetes pod. The application can run both inside and outside a Kubernetes cluster, automatically detecting its environment to configure the Kubernetes client.

Building and Running

Prerequisites

• Go (version 1.22 or later)
• Docker
• A Kubernetes cluster (e.g., Minikube, Kind, or a cloud-based provider)
• kubectl configured to interact with your cluster

Local Development

To run the application locally, you will need to have a Kubernetes cluster accessible and your kubeconfig file properly configured.

1. Clone the repository:

   git clone https://github.com/moficodes/ippr.git
   cd ippr

2. Run the application:

   go run .

   The application will start on port 8080. By default, it will try to connect to a pod named ippr in the ippr namespace. You can change this by setting the POD_NAME and NAMESPACE environment variables.

Docker Build

To build the Docker image:

docker build -t ippr:latest .

The Dockerfile uses a multi-stage build to create a minimal final image.

Kubernetes Deployment

The k8s directory contains the necessary Kubernetes manifests to deploy the application.

1. Create the namespace:

   kubectl create namespace ippr

2. Apply the manifests:

   kubectl apply -f k8s/

This will create a pod, a service account, and a service in the ippr namespace.
