When deploying NKP using the Nutanix provisioning method (CAPX), what are the supported OS platforms?

The NKPA course specifies the supported operating systems for NKP clusters deployed using the Nutanix provisioning method (CAPX), which leverages Cluster API for Nutanix (CAPX) to provision clusters on Nutanix AHV. The supported OS platforms for CAPX areRocky LinuxandUbuntu, as these distributions are tested and optimized for Nutanix infrastructure and Kubernetes requirements.

Rocky Linux is a CentOS replacement adopted by Nutanix after CentOS 8’s end-of-life in 2021, providing a stable, enterprise-grade OS. Ubuntu, particularly LTS versions like 20.04 or 22.04, is widely supported due to its compatibility with Kubernetes and Nutanix AHV. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “When deploying NKP with the Nutanix provisioning method (CAPX), the supported OS platforms are Rocky Linux and Ubuntu, ensuring compatibility with Nutanix AHV and Kubernetes.” These OS images are typically prepared using NKP Image Builder (NIB) to include necessary components like kubeadm and containerd.

Incorrect Options:

A. CentOS and Rocky Linux: CentOS 8 is no longer supported post-2021, and Nutanix has shifted to Rocky Linux.

C. Flatcar, Rocky Linux, and Ubuntu: Flatcar Container Linux is not a supported OS for CAPX in NKP deployments.

D. CentOS and Ubuntu: CentOS is not supported, as noted above.
