Kubernetes is an open-source container-orchestration system for automating computer application deployment, scaling, and management.

Kubernetes follows an N-2 support policy (meaning that the 3 most recent minor versions receive security and bug fixes). This generally results in a particular minor version being supported for approximately 9 months.

See the Release Versioning page to determine what counts as a major/minor/patch release.

Applicable fixes, including security fixes, may be backported to those three release branches, depending on severity and feasibility. Patch releases are cut from those branches at a regular cadence, plus additional urgent releases, when required. The Release Managers group owns this decision. For more information, see the patch release page, which also lists expected release dates for future releases, along with exact EoL dates for all active branches.

Since Kubernetes has a client-server architecture, there is a supported version skew between the client/server, which also determines the supported component upgrade order.

More information is available on the Kubernetes website.

You should be running one of the supported release numbers listed above in the rightmost column.

You can check the version that you are currently using by running:

kubectl version
