Frequently Asked Questions
Can this process multiple Kubernetes documents?
Yes. YAML documents separated by --- are formatted and checked independently.
What fields are checked?
The validator checks apiVersion, kind, metadata.name, and containers for common workload kinds.
Does it contact a Kubernetes cluster?
No. This is a local static check and never connects to a cluster.
Does it support Services and ConfigMaps?
Yes. Any object with required Kubernetes metadata can be formatted; workload-specific container checks are added where relevant.
Is my manifest uploaded?
No. YAML parsing and diagnostics run entirely in your browser.
