Kubernetes YAML Generator - Free Online IT Tool

☸️ Kubernetes YAML Generator

Generate basic K8s Deployment and Service manifests for your application.

ℹ️ About Kubernetes YAML Generator

The Kubernetes YAML Generator is a scaffolding tool designed to jumpstart the deployment of your applications into a Kubernetes cluster. Writing YAML manifests from scratch is error-prone and requires memorizing the complex API structure of Deployments and Services.

This tool generates a production-ready baseline manifest that includes a Deployment (controlling your pods and replicas) and a corresponding Service (providing a stable network endpoint). It follows standard best practices for labeling and selector matching, ensuring that your service correctly routes traffic to your pods from day one. This is an ideal tool for developers moving from Docker to Kubernetes or for SREs quickly prototyping new services.

📖 How to use Kubernetes YAML Generator

1. Provide a name for your application (e.g., <code>user-api</code>).
2. Enter the full image path from your registry (e.g., <code>ghcr.io/org/image:latest</code>).
3. Select the number of replicas (instances) you want to run for high availability.
4. Click 'Run Tool' to generate the multi-resource YAML manifest.
5. Save the output to a file (e.g., <code>deploy.yaml</code>) and apply it using <code>kubectl apply -f deploy.yaml</code>.

❓ Frequently Asked Questions

What is a 'Replica' in Kubernetes?

A replica is an identical copy of your pod. Running multiple replicas ensures that if one instance crashes, others are available to handle traffic, providing high availability.

Why does it generate two resources?

The 'Deployment' manages the application software, while the 'Service' provides the network identity (IP and DNS) so other parts of your cluster can find the application.

Can I change the port?

The generator defaults to port 80. For other ports, you can manually edit the <code>containerPort</code> and <code>port</code> fields in the generated YAML.
