Kubernetes Deployment Generator

Generate a Kubernetes Deployment manifest with configurable replicas, container image, ports, and resource limits.

Configure your app's name, image, replicas, and ports - this tool generates a valid Deployment manifest with the fields most deployments need.

Pair this with the Kubernetes Service Generator to expose the resulting Deployment's pods within the cluster.

What Is a Kubernetes Deployment?

A Deployment manages a set of identical, replicated Pods running your application - it handles rolling updates, scaling replica count, and restarting failed Pods automatically, and is the standard way to run stateless workloads on Kubernetes.

Why Use This Tool?

A Deployment manifest has several nested levels (Deployment → template → PodSpec → containers) that are easy to indent incorrectly by hand. This tool generates a correctly-nested, valid structure from simple field inputs.

How to Use It

Enter a Deployment name, container image, and replica count.
Add container ports and any environment variables.
Optionally set CPU/memory requests and limits.
Copy the generated YAML and apply it with kubectl apply -f.

Limitations

This is a common-pattern starting Deployment, not a guarantee of production-readiness - review resource limits, liveness/readiness probes, and security context settings for your specific workload before relying on it.

Frequently Asked Questions

The Deployment uses spec.selector to find the pods it manages. If it does not match the labels in spec.template, Kubernetes rejects the manifest.

Requests are what the scheduler reserves for the container; limits are the maximum it may use. A container that exceeds its memory limit is killed (OOMKilled).

Run kubectl rollout undo deployment/<name>. kubectl rollout history deployment/<name> shows previous revisions.
