About:
Kubent scans Kubernetes clusters and manifest files to identify deprecated APIs that are slated for removal. It helps prevent service disruptions by flagging resources using old API versions before they become unsupported. This proactive approach ensures smooth cluster upgrades and maintains compatibility with newer Kubernetes releases.

Key Features:

Live cluster scanning and manifest analysis
Supports multiple output formats (JSON, CSV, default)
Checks against multiple Kubernetes versions
Identifies remediation suggestions for deprecated resources

Use Cases:

Preparing for a Kubernetes version upgrade
Auditing existing cluster configurations for technical debt
CI/CD pipeline integration to block deprecated API usage

Alternatives:

pluto – Similar functionality; pluto focuses heavily on output formatting and CI integration.
kube-fixer – Focuses on automated remediation rather than just detection.
