Kubernetes Best-Practices Checker

The Best-Practices Checker audits pasted Kubernetes manifests for the most common production mistakes: containers without CPU/memory limits or requests, without liveness or readiness probes, and containers that run as root.

Paste one or more manifests (Pod, Deployment, StatefulSet, DaemonSet or Job). The tool walks every container and reports each issue with a severity tag so you can prioritise fixes.

Nothing is uploaded. The YAML is parsed and analysed entirely in your browser.

• Limits & requests - flags missing CPU/memory limits and requests.
• Probes - flags missing liveness/readiness probes.
• Root check - flags containers running as root.
• Multi-doc - analyse several manifests at once.
• Copy / Download / Print - export the report.

1. Paste your manifest(s) into the YAML box.
2. Click Check.
3. Review the findings and fix each container.

Example 1 - missing limits. A container with no resources block is flagged HIGH.

Example 2 - root. A container without runAsNonRoot is flagged HIGH.

Example 3 - clean. A fully configured container reports no violations.

• Fast audit - find mistakes before they reach production.
• Severity tags - focus on HIGH first.
• Private - runs fully in the browser.
• Exportable - copy, download or print the report.
