Kubernetes YAML Validator
How to Use the Kubernetes YAML Validator
Paste a Kubernetes manifest to check its YAML structure and common manifest fields before applying it to a cluster. This helps catch simple configuration mistakes earlier in a deployment workflow.
Practical Example
A Deployment manifest missing a required apiVersion or kind field can be flagged for review before you run kubectl apply.
Factors That Affect the Result
Kubernetes version, resource type, custom resource definitions, indentation, field names and schema-specific rules affect validation. Basic browser checks cannot replace server-side cluster validation.
Frequently Asked Questions
Does this connect to my cluster?
No, it performs local or basic manifest checks rather than live cluster validation.
Can it validate custom resources?
Basic YAML may be checked, but CRD-specific schema rules may require the actual cluster schema.
Should I still test with kubectl?
Yes, use cluster-side validation before deployment.
