Kubernetes Manifest, Intentionally Invalid

An intentionally invalid Kubernetes manifest: a removed apiVersion, a quoted string where replicas needs an integer, a selector that does not match the pod template, and containers as a mapping instead of a list. Four documented faults for a validator to report.

# INTENTIONALLY INVALID. Well-formed YAML, invalid Kubernetes in four documented ways:
#   1. `apiVersion: apps/v1beta1` was removed in Kubernetes 1.16
#   2. `replicas` is a quoted string where an integer is required
#   3. `spec.selector` does not match the pod template labels
#   4. `containers` is a mapping where a list is required
apiVersion: apps/v1beta1

Scenario
Validate a well-formed YAML manifest against the Kubernetes API schema
Expected result
Validation fails with at least 4 errors, and the removed apps/v1beta1 apiVersion is reported separately from the selector/template label mismatch

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 Manifest, Intentionally Invalid” is a deterministic Testaroo fixture for Error handling, Config parsing, Schema validation. Deliberately corrupt and invalid files, clearly labelled, for testing how your tool fails.

Documented properties for this file: YAML · 691 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.

Code examples

import yaml  # pip install pyyaml

with open("invalid-apiversion.yaml") as f:
    data = yaml.safe_load(f)
print(data)
