Kubernetes Manifest Helper

Inspect Kubernetes YAML — resource inventory, structural validation, cross-resource relationships (Service ↔ Pod labels, Ingress → Service, HPA → target, ConfigMap/Secret/volume refs), readiness (probes / resources / replicas), and pod-security findings — or switch to Generate and build a manifest bundle (Deployment + Service / Ingress / ConfigMap / Secret / HPA / PDB / PVC / Namespace, or a standalone CronJob / ConfigMap / Secret) from a guided form. Runs in your browser; manifests are never uploaded. For a dedicated pod-security scan, see the K8s Policy Inspector.

How to use the Kubernetes Manifest Helper

Generate, inspect, validate, and improve Kubernetes YAML manifests for the resources you actually use: Deployment, Service, Ingress, ConfigMap, Secret, HorizontalPodAutoscaler (HPA), CronJob, Job, PersistentVolumeClaim, RBAC (Role / RoleBinding / ServiceAccount), and NetworkPolicy. Generate starters from a simple form, paste existing manifests for validation, and get best-practice warnings before kubectl apply. Runs locally; manifests are never uploaded.

What it does

Generates templates for Deployment, Service, Ingress, ConfigMap, Secret, HPA, CronJob, Job, PVC, ServiceAccount, Role / RoleBinding, NetworkPolicy.
Form-driven inputs (name, namespace, image, port, env, replicas) produce idiomatic YAML.
Validates pasted manifests: missing apiVersion, kind, metadata.name; obvious schema mistakes; selector/label mismatches.
Best-practice checks: missing resource requests / limits, missing livenessProbe / readinessProbe, latest tag, plain Secret with stringData visible.
ConfigMap and Secret accept KEY=value input for fast scaffolding.
Multi-document YAML (---) is supported across generation and validation.

When to use it

Bootstrap a new service with Deployment + Service + Ingress quickly.
Add an HPA or NetworkPolicy to an existing service without memorizing the schema.
Validate a manifest pasted from a ticket before applying it.
Convert KEY=value env vars into a proper ConfigMap or Secret YAML.
Catch missing probes / resource limits before a code review.
Produce a starter to hand off to a platform team.

How to use it

Pick the resource you need (Deployment, Service, Ingress, etc.) in the generator.
Fill in name, namespace, image, port, replicas, and any extras (env, labels, probes).
Copy or download the generated YAML, then refine for cluster-specific annotations.
To check an existing manifest, paste it into the validation tab — best-practice warnings are listed inline.
Pair with the YAML Validator for pure syntax checks and the ENV Converter for Kubernetes Secret generation from .env.

Tips & pitfalls

The selector on a Service must match the labels on Pods — the most common reason a service has 0 endpoints.
Always set resource requests / limits and at least a readiness probe in production.
Avoid the latest image tag — pin to a digest or semantic tag for reproducible deploys.
A Kubernetes Secret with data: requires Base64-encoded values; stringData: takes plain values.
Ingress resources differ by controller (NGINX, Traefik, GKE) — annotations are non-portable.
This tool generates YAML and validates structure — it does not connect to a cluster.

FAQ

How do I create a Kubernetes Deployment YAML? Use the Deployment generator; fill in name, image, port, replicas; copy the YAML.
How do I generate a Kubernetes Secret from a .env file? Use the ENV Converter and pick Secret as the output, or paste the env into the Secret generator.
Does this tool deploy to my cluster? No — it only generates and validates YAML. Apply with kubectl apply yourself.
Will it catch all manifest errors? No — it flags common issues but does not run a full schema check. Use kubectl --dry-run=server for full validation.
Are pasted manifests uploaded? No. All validation and generation runs in your browser.
What about CRDs? CRDs require their own schemas; the helper covers core resources, not custom resources.

Runs locally in your browser. No uploads. The helper generates YAML — never apply to a cluster without review.
