Advanced ValidKube: The Ultimate Kubernetes Manifest Security Tool
Welcome to the Advanced ValidKube tool, your all-in-one solution for validating, cleaning, securing, and auditing Kubernetes YAML manifests. Whether you are a DevOps engineer, SRE, or developer, ensuring your Kubernetes configurations are error-free and secure is critical.This Tool is Totally Free and runs directly in your browser with secure backend processing.
Validation
Instantly validate your YAML syntax and structure against standard Kubernetes schemas. Catch typos and missing fields before deployment.
Clean (kubectl-neat)
Remove clutter like `managedFields`, `status`, and system annotations to make your manifests readable and version-control friendly.
Secure (Trivy)
Scan for security vulnerabilities and misconfigurations. Detect privileged containers, missing resource limits, and more.
Audit (Polaris)
Audit your resources against best practices. Ensure reliability, efficiency, and stability of your Kubernetes workloads.
Why use this Free Tool?
- No Login Required: Just paste your YAML and get instant results.
- Secure & Private: We processes your data securely and discard it immediately after analysis.
- Detailed Insights: Unlike other basic validators, we provide comprehensive cleanup and security audits.
How it works
Our tool leverages industry-standard open-source logic to analyze your Kubernetes manifests. We verify the API versions, kinds, and metadata. For security scanning, we check for common pitfalls such as running as root, privilege escalation, and missing resource quotas.
Regularly auditing your manifests helps prevent deployment failures and potential security breaches in your production clusters.
Frequently Asked Questions
Common questions about ValidKube, Kubernetes YAML validation, and security auditing.
How does ValidKube validate Kubernetes YAML manifests against official schemas?
ValidKube uses logic similar to kubeval to cross-reference your YAML against the official Kubernetes JSON schemas for various API versions (e.g., apps/v1, batch/v1). Additional checks ensure field types match and required fields like metadata.name are present, preventing ValidationError(Deployment.spec): unknown field errors during kubectl apply.
Can I use ValidKube to clean up "kubectl get -o yaml" output online?
Yes, the "Clean" feature functions like kubectl-neat. It strips system-generated metadata such as managedFields, creationTimestamp, uid, and status blocks. This eliminates noise when migrating resources or committing manifests to Git, solving the common issues of cluttered kubectl get exports.
What specific Kubernetes security vulnerabilities does the Trivy scanner detect?
The "Secure" scan, powered by Trivy logic, identifies misconfigurations like privilege escalation risks (securityContext.allowPrivilegeEscalation: true), running containers as root (runAsUser: 0), and missing resource limits. It generates alerts for vulnerabilities that could lead to PodSecurityPolicy violations or runtime exploits.
How does ValidKube help with Kubernetes Best Practices auditing?
The "Audit" feature checks for reliability and efficiency best practices, similar to Polaris. It flags issues like missing liveness/readiness probes, undefined resource requests/limits (CPU/Memory), and usage of deprecated APIs. This helps prevent CrashLoopBackOff and OOMKilled errors in production.
Is it safe to paste sensitive Kubernetes YAML manifests into ValidKube?
Yes. ValidKube is designed with privacy in mind. We process your YAML manifests in a secure, ephemeral backend environment solely for analysis. No data is stored, logged, or shared. Once the session ends, your data is permanently discarded.
Why do I get "apiVersion: v1" errors when validating certain resources?
This error often occurs if you are using deprecated APIs or incorrect indentation. ValidKube highlights the exact line causing the schema mismatch. For instance, using extensions/v1beta1 for Ingress in newer K8s versions will trigger a validation error, guiding you to update to networking.k8s.io/v1.
Does ValidKube generate SBOMs (Software Bill of Materials) for K8s manifests?
Yes, using the "SBOM" option, you can generate a CycloneDX compatible Software Bill of Materials for the images defined in your manifests. This is crucial for supply chain security compliance and tracking CVEs across your container images.
Can I debug "ImagePullBackOff" or "CreateContainerConfigError" using this tool?
While these are runtime errors, ValidKube prevents them by ensuring your YAML structure is correct before deployment. It checks for syntax errors that cause CreateContainerConfigError. For ImagePullBackOff, ensuring you have the correct image field format is part of the validation, though connectivity issues are runtime-specific.
