Question 1

What happens when Chef Infra Client reaches end of life?

Accepted Answer

When Chef Infra Client reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 8 Chef Infra Client versions are already EOL. The latest supported version is Chef Infra Client 19. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Chef Infra Client 19 still supported?

Accepted Answer

Yes. Chef Infra Client 19 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Chef Infra Client releases and their exact end-of-life dates.

Question 3

Is it safe to use Chef Infra Client after end of life?

Accepted Answer

No. Running Chef Infra Client 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 Chef Infra Client release.

Question 4

How to upgrade from Chef Infra Client 17 to Chef Infra Client 19.x?

Accepted Answer

To upgrade Chef Infra Client from 17 to 19: (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 Chef Infra Client LTS version?

Accepted Answer

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

Question 6

How long does Chef Infra Client support each version?
