How to Use the Pod YAML Analyzer
Paste any standard Kubernetes Pod, Deployment, StatefulSet, DaemonSet, or custom Operator resource YAML into the editor. The analyzer parses your structure entirely within your browser using a bundled local JavaScript YAML parser. It checks configuration semantics against recommended production practices, alerting you to common runtime issues before you apply manifests to your cluster.
Critical Checks Performed
Resource Requests and Limits
Missing CPU or memory limits risks container starvation and causes nodes to kill pods under memory pressure (OOMKilled exit code 137). Setting both establishes the Guaranteed or Burstable QoS class.
Liveness, Readiness & Startup Probes
Probes ensure Kubernetes knows when an operator controller is ready to reconcile custom resources and when a wedged process needs an automated restart.
Pod Security Standards
Audits for runAsNonRoot, readOnlyRootFilesystem, and allowPrivilegeEscalation: false. Operator controllers should adhere to the Kubernetes Restricted security profile.
Image Tag Hygiene
Flags mutable tags such as ":latest" or missing tags. Production operator pods require immutable version tags or SHA256 digest pins to ensure deterministic rollouts.
Important Limitation Notice
This tool performs client-side static linting and best-practice heuristic audits. It does not replace Kubernetes apiserver schema validation, CustomResourceDefinition OpenAPI schemas, or admission webhooks (such as Kyverno or OPA Gatekeeper). Always dry-run manifests against your target cluster using "kubectl apply –dry-run=server -f manifest.yaml" before production rollout.
Why Static YAML Analysis Matters for Kubernetes Operators
Kubernetes operators are stateful control loops that automate complex infrastructure such as databases, message queues, and distributed caches. A syntax or configuration oversight in an operator’s Deployment or Pod specification can halt reconciliation across dozens of custom resources. The Kubernetes Pod YAML Analyzer provides immediate, safe, client-side feedback before applying manifests to staging or production clusters.
Key Production Checks Performed
- Resource Requests & Limits: Verifies CPU and memory boundaries to avoid noisy-neighbor contention and host-node Out-Of-Memory (OOM) kills.
- Liveness, Readiness, and Startup Probes: Ensures the kubelet knows when an operator is ready to handle traffic and when a deadlocked container requires restarting.
- Restricted SecurityContext: Confirms runAsNonRoot, readOnlyRootFilesystem, and allowPrivilegeEscalation: false are configured according to the Kubernetes Pod Security Standards.
- Image Tag Immutability: Flags mutable tags such as “:latest” to ensure deterministic GitOps rollouts.
