Kubernetes Bundles

Kubernetes Bundles are software packages that can contain software to support newer Kubernetes versions, updated add-ons, and software fixes. Kubernetes Bundles enable you to update your deployment without requiring you to upgrade to a newer version of HPE Ezmeral Runtime Enterprise.

Contents of Kubernetes Bundles

The contents of a Kubernetes bundle can vary. A Kubernetes bundle might include one or more of the following:

  • Support for a newer version of Kubernetes
  • New versions of application add-ons
  • Software or Common Vulnerabilities and Exposures (CVEs) fixes for Kubernetes and add-on versions packaged in previous Kubernetes Bundles

To view the contents of a specific Kubernetes bundle, see Updates Tab.

Kubernetes Bundle Versions

The Kubernetes bundle version provides information about the scope of the updated software. Kubernetes bundle versions follow the industry-standard format:

<major>.<minor>.<maintenance>

In the <major>.<minor>.<maintenance> format, a number represents each type of version:

  • The first number, the <major> version, changes when the bundle contains a newer Kubernetes version or an add-on version is not compatible with a previous version of HPE Ezmeral Runtime Enterprise. All Kubernetes bundle versions that have the same <major> version numbers are compatible with the same set of HPE Ezmeral Runtime Enterprise versions.

    When the <major> increments, the <minor> and <maintenance> versions are reset to zero, even though the Kubernetes bundle might also contain minor or maintenance updates.

  • The second number, the <minor> version, changes when the bundle contains support for newer Kubernetes minor versions, newer add-on versions, or both.

    When the <minor> version increments, the <maintenance> version is reset to zero, even though the Kubernetes bundle might also contain maintenance updates.

  • The third number, the <maintenance> version, changes when bundle contains one or more Kubernetes patches, add-on patches, or CVE fixes.

Kubernetes Bundle Compatibility

Kubernetes bundles are compatible with the versions of HPE Ezmeral Runtime Enterprise as listed in the Support Matrixes.

Support Life Cycle of Kubernetes Bundles

A Kubernetes bundle is supported for 12 months following its first major release. A Kubernetes bundle and its subsequent minor and maintenance updates, if any, share the same End-Of-Life (EOL) date.

For example, if the first release of a Kubernetes bundle is 1.0.3 and the bundle reaches End-Of-Life (EOL) in October of 2023, then Kubernetes bundle 1.1.0 and Kubernetes bundle 1.2.2 also reach EOL in October of 2023.
