How to use Kubernetes and CI YAML Checker

  1. Choose Kubernetes resources or a GitHub Actions workflow.
  2. Paste YAML and run the selected checks.
  3. Read issues and unvalidated areas before testing in the actual platform.

Example: Kubernetes and CI YAML Checker

A GitHub workflow with an on trigger and one job containing a run step.

You add
Document type: kubernetes YAML source: apiVersion: v1 kind: Pod metadata: name: example-pod spec: containers: - name: app image: nginx:1.28 ports: - containerPort: 8080
You get
Reviewed 1 resource/job records and found 2 items to check. Sample rows: 1 | /spec/containers/0/image | review | Image is not pinned to a SHA-256 digest; tags can change.; 1 | /spec/containers/0/resources | review | Explicit CPU/memory requests and limits need review..

Options

Document type
Select Kubernetes or the supported GitHub workflow mode. The selected rules do not validate arbitrary YAML or a different CI provider.
Findings
Inspect the named resource or job and the rule behind each observation. Unknown structures need review rather than an assumption that they passed.

Supported inputs and limits

Dated structural checks for selected Kubernetes API kinds and GitHub Actions workflow fields. No cluster admission, complete schemas, action verification, expression execution or GitLab validation. Safe YAML only; aliases, merges, custom tags and duplicate keys are refused. Unknown structures remain explicit. Selected resources: v1 Pod, Service and ConfigMap, and apps/v1 Deployment. GitHub Actions checks are a dated subset.

Valid YAML and operational validity differ

A YAML document can parse while using an unavailable API version, action or runtime value. This page does not contact a cluster, validate complete schemas or execute workflow expressions. Review the dated coverage and test the intended configuration in its own platform. Do not copy a structural pass as a deployment or security approval.

Questions about Kubernetes and CI YAML Checker

Does this replace cluster or workflow validation?

No. Platform-specific validation and actual execution still need separate checks.

Are shell commands or actions executed?

No. They remain text in the submitted YAML.

Can I check a GitLab pipeline?

No. The CI checks here target the supported GitHub Actions structure.
