Kubernetes StatefulSet with Volume Claim Templates
A StatefulSet with volumeClaimTemplates, an ordered pod-management policy, a partitioned rolling update, and a non-root pod security context. For testing manifest linters and admission policies that reason about storage and identity.

What is a .yaml file?
YAML (YAML Ain't Markup Language) is a human-readable data-serialization format using indentation, key-value pairs, and lists, and is a superset of JSON. It supports comments, anchors, and multiple documents per file, favoring readability for configuration. Its indentation sensitivity makes it error-prone to hand-edit.
How to use this file
Use an example YAML file to test config parsers, indentation and anchor handling, multi-document streams, and safe-loading to avoid arbitrary object construction.
How to use this file for testing
“Kubernetes StatefulSet with Volume Claim Templates” is a deterministic Novus Examples fixture for Config testing, Config parsing, Editor testing. TOML, INI, YAML, .env, and dotfile configuration samples with nested sections and typed values — for testing config parsers, loaders, and environment tooling.
Documented properties for this file: YAML · 1,043 bytes. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Pipeline and infrastructure fixtures are inert configuration: steps reference fictional images and scripts, and nothing here executes. Run your linter, schema validator, migrator, or policy engine against them, and expect the deprecated-syntax and intentionally invalid variants to be rejected.
Point your config loader at the file and assert it reads the documented sections and typed values, including any deliberately-tricky nesting or comments.
Code examples
import yaml # pip install pyyaml
with open("statefulset-volumeclaims.yaml") as f:
data = yaml.safe_load(f)

- yamlKubernetes CronJob Schedule and History LimitsA CronJob with an explicit timeZone, Forbid concurrency, a starting deadline, and history limits on both success and failure. For testing cron parsing and the scheduling fields policy engines most often check.
- yamlKubernetes HorizontalPodAutoscaler (autoscaling/v2)An autoscaling/v2 HPA with both a Resource and a Pods metric, plus scaleUp and scaleDown behaviour policies. The v2 metric shape differs sharply from v1 and v2beta, which is what makes it a useful conversion fixture.
- yamlKubernetes Kustomization OverlayA Kustomize overlay with a name prefix and suffix, common labels, an image tag override, a configMapGenerator merge, and a JSON-6902 patch embedded as a block scalar — YAML inside YAML, which naive rewriters mangle.
- yamlKubernetes Multi-Document Manifest BundleThree Kubernetes objects in one YAML stream, the shape kubectl apply consumes. A loader that calls the single-document API returns only the first object and silently drops the other two, which is exactly the failure this fixture is for.
- yamlKubernetes Namespace, ResourceQuota, and LimitRangeA three-document governance bundle. Its real edge case is quantity handling: values like "8", 16Gi and 250m are Kubernetes quantity strings, and a parser that coerces the quoted ones to numbers or normalises the suffixed ones changes their meaning.
- yamlKubernetes NetworkPolicy with Ingress and EgressA NetworkPolicy with both policy types: an ingress rule combining namespace and pod selectors, and two egress rules, one of which uses an ipBlock with an except range. For testing policy engines that reason about allowed traffic.
