Question 1

What happens when Kubernetes Node Feature Discovery reaches end of life?

Accepted Answer

When Kubernetes Node Feature Discovery reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 5 Kubernetes Node Feature Discovery versions are already EOL. The latest supported version is Kubernetes Node Feature Discovery 0.18. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Kubernetes Node Feature Discovery 0.18 still supported?

Accepted Answer

Yes. Kubernetes Node Feature Discovery 0.18 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Kubernetes Node Feature Discovery releases and their exact end-of-life dates.

Question 3

Is it safe to use Kubernetes Node Feature Discovery after end of life?

Accepted Answer

No. Running Kubernetes Node Feature Discovery after EOL is not safe for production systems. Once a version reaches end of life, newly discovered CVEs are published publicly but never patched — leaving your systems permanently exposed. The only safe path is upgrading to an actively supported Kubernetes Node Feature Discovery release.

Question 4

How to upgrade from Kubernetes Node Feature Discovery 0.16 to Kubernetes Node Feature Discovery 0.x?

Accepted Answer

To upgrade Kubernetes Node Feature Discovery from 0.16 to 0.18: (1) review the official migration guide for breaking changes, (2) test your application against the new version in a staging environment, (3) update dependencies that have version constraints, (4) run your full test suite, (5) deploy with a rollback plan. The earlier you start, the more time you have to resolve compatibility issues before EOL.

Question 5

When is the next Kubernetes Node Feature Discovery LTS version?

Accepted Answer

Not all Kubernetes Node Feature Discovery releases have a designated LTS status. Check the version table above — LTS releases are marked with an "LTS" badge. Refer to the official Kubernetes Node Feature Discovery release policy for information on upcoming long-term support versions.

Question 6

How long does Kubernetes Node Feature Discovery support each version?

Accepted Answer

On average, Kubernetes Node Feature Discovery supports each release for approximately 13 months (~1.1 years).  The exact EOL date for each version is listed in the table above.
