Kubernetes Deployment YAML Generator
Used by developers, writers, and creators worldwide.
A Kubernetes deployment YAML generator produces a complete Deployment and Service manifest so you can ship a containerised app to a cluster without hand-writing brittle YAML. Enter an app name and a replica count and it returns a Deployment with matching labels and selectors, a container with a port, sensible CPU and memory requests and limits, plus a Service that routes traffic to the pods. Platform and backend engineers use it to scaffold a new workload, teach the structure of a manifest, or avoid the indentation mistakes that make kubectl reject a file. It runs in your browser and generates instantly. Save it as a .yaml file, swap the image reference for your real registry path, adjust the ports and resource sizes, then apply it with kubectl. The resource requests and limits are included by default because clusters schedule and protect pods far better when every container declares them.

How to use
- Choose your options above
- Click Generate
- Copy your result
Detailed instructions
- Enter your app name.
- Set the number of replicas.
- Click Generate to produce the manifest.
- Swap in your image and run kubectl apply -f.
Use Cases
- •Scaffolding a new Kubernetes workload
- •Learning how a Deployment and Service fit together
- •Avoiding YAML indentation errors that break kubectl
- •Setting sensible resource requests and limits
- •Standardising manifests across services
Tips
- →Pin a real image tag rather than latest for reproducible rollouts.
- →Add readiness and liveness probes before going to production.
- →Keep requests realistic so the scheduler can pack nodes well.
- →Store manifests in git so changes are reviewable.
FAQ
why include resource requests and limits
Requests let the scheduler place pods on nodes with enough capacity, and limits stop a runaway container from starving its neighbours. Declaring both makes your workload a good cluster citizen and easier to autoscale.
how do the labels work
The Deployment selector, the pod template labels, and the Service selector all share the same app label. That shared label is how the Deployment finds its pods and how the Service routes traffic to them.
what do I change before applying
Replace the image with your real registry path and tag, set the container port to match your app, and adjust the resource sizes to your workload. Then run kubectl apply -f on the file.
