Are my cluster configurations sent to a server?
No. Enterprise security is our top priority. The validation logic runs entirely within your browser's local sandbox, meaning your private cluster configurations and secrets are never transmitted.

01
How Kubernetes YAML Validator Works
Utilizing a strict YAML parsing engine (`js-yaml`), the tool separates multi-document manifests (separated by `---`) and analyzes each object individually. It checks for structural integrity and applies heuristic rules (like enforcing resource limits) purely in the browser.

Key Features of Kubernetes YAML Validator
Supports multi-document YAML stream parsing
Instant detection of deprecated `apiVersion` strings
Highlights missing resource limits (anti-pattern detection)
100% client-side validation for zero-trust enterprise security
03
Practical Application & Code Integration
Use-Case Context
Kubernetes (K8s) is entirely declarative via YAML manifests. A single indentation error or an outdated API version (`apps/v1beta1` instead of `apps/v1`) will cause the `kubectl apply` command to fail. Validating K8s YAML locally prevents broken deployments from ever reaching the production cluster.

Common Questions About Kubernetes YAML Validator
Why is it warning me about missing resource limits?
Deploying pods without strict CPU and memory `requests` and `limits` is a Kubernetes anti-pattern. It can lead to noisy neighbor problems or node exhaustion, which is why our linter flags it as a warning.
