Kubernetes Sanity Check Pod

This repository contains a Kubernetes pod configuration designed for performing basic sanity checks within a Kubernetes cluster. It is useful for troubleshooting, testing connectivity, and verifying that a Kubernetes environment is functioning as expected.

Features

  • Sanity Check Pod: Simple pod for performing basic network connectivity and service availability checks.
  • Custom Commands: Can run custom diagnostic commands within the pod.
  • Minimalistic and Lightweight: Uses a lightweight container image for fast startup.

Prerequisites

  • Kubernetes Cluster: A running Kubernetes cluster.
  • kubectl: Installed and configured to interact with your Kubernetes cluster.

Project Structure

/
├── /sanity-check-pod.yaml                  # Kubernetes Pod YAML configuration
├── /scripts/                               # Optional scripts for testing
├── /Dockerfile                             # Dockerfile to build a custom image (optional)
└── /README.md                              # Project README (this file)

Usage

1. Clone the Repository

git clone https://github.com/vishnuswmech/sanity-check-pod.git
cd sanity-check-pod

2. Deploy the Sanity Check Pod

Apply the provided Kubernetes pod configuration:

kubectl apply -f sanity-check-pod.yaml

This will deploy a simple pod that you can use to test your Kubernetes environment.

3. Verify Pod Status

Ensure the pod is running by checking its status:

kubectl get pods

Once the pod is in a Running state, you can execute commands inside the pod.

4. Running Commands in the Pod

You can execute commands inside the sanity check pod for diagnostics. For example, to test connectivity to another service:

kubectl exec -it <pod-name> -- ping google.com

You can replace <pod-name> with the actual pod name retrieved from the kubectl get pods command.

5. Deleting the Pod

To clean up and delete the sanity check pod:

kubectl delete -f sanity-check-pod.yaml

Custom Docker Image (Optional)

The repository includes a Dockerfile for creating a custom image for the sanity check pod. You can build and use your own image if needed:

docker build -t sanity-check:latest .

Then, you can modify the sanity-check-pod.yaml to use your custom image.
