Manifest Inspector

Manifest Inspector

Paste or upload a multi-document YAML file to inspect it locally. The inspector identifies apiVersion, kind, name, and namespace for each document, surfaces common problems such as missing metadata.name, latest image tags, and missing resource limits, and highlights Kustomize-specific references. No cluster access. No uploads.

Example findings

#1  Deployment  apps/v1  demo-app
    warning: container image "nginx:latest" uses tag "latest".
    warning: Deployment containers are missing resources.requests/limits.
#2  Service     v1       demo-app
#3  Kustomization  kustomize.config.k8s.io/v1beta1  demo-app
    kustomize ref: resource deployment.yaml
    kustomize ref: image[0] nginx

Frequently asked questions

Is my YAML uploaded anywhere?
No. Parsing and inspection happen in your browser. No network request is made that contains your manifest content.
What does the inspector check?
It identifies apiVersion, kind, name, and namespace for each document, flags missing metadata.name, warns about container images tagged latest or missing a tag, and warns about Deployments, StatefulSets, DaemonSets, Pods, Jobs, and CronJobs that lack resource requests and limits.
Does it validate against a Kubernetes API server?
No. The checks are static and offline. The tool does not connect to a cluster and does not run kubectl. Use it as a first-pass review before applying manifests.
Can it parse multi-document YAML files?
Yes. Documents separated by --- are parsed individually. Each document is shown with its index, kind, and name. Empty documents in the stream are skipped without errors.
Does it recognize Kustomization resources?
Yes. When a document has kind: Kustomization the inspector lists its resources, patches, images, configMapGenerator, secretGenerator, namePrefix, nameSuffix, namespace, commonLabels, and commonAnnotations in a dedicated Kustomize references panel.
