The exhibit indicates an error during the creation of a bootstrap cluster using the nkp create bootstrap command in an air-gapped environment. The NKPA course explains that a bootstrap cluster is a temporary Kubernetes cluster used to initialize Cluster API (CAPI) components for provisioning the target NKP cluster.
In an air-gapped environment, all required resources, including container images, must be available locally since there is no Internet access to pull them from public registries.
The most likely reason for the error is that the bootstrap cluster image needs to be loaded prior to creating the bootstrap cluster (Option B). The course specifies that in air-gapped deployments, the bootstrap cluster image (typically a kind or k3s image used by CAPI) must be pre-loaded into a local container registry or the bastion host before running nkp create bootstrap. This image is part of the Air-Gapped Bundle provided by Nutanix, which includes all necessary container images for NKP deployment. Without pre-loading this image, the nkp create bootstrap command fails because it cannot pull the required image.
The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: "In an air-gapped NKP deployment, ensure the bootstrap cluster image (e.g., kindest/node) is loaded into a local registry or host before executing nkp create bootstrap, as the command requires this image to create the temporary cluster." The engineer must extract the bootstrap image from the Air-Gapped Bundle, load it using docker load or similar, and configure the local registry to make it accessible during the bootstrap process.
Incorrect Options:
* A. The CAPI provisioning method needs to be specified as nkp create bootstrap nutanix: The nkp create bootstrap command does not require a provisioning method like nutanix at this stage; the provider (e.g., CAPX for Nutanix) is specified during the actual cluster creation (nkp create cluster), not bootstrap creation.
* C. The Ubuntu 22.04 OS image needs to be NIB-prepped prior to creating the bootstrap: The Ubuntu 22.04 image is for the target NKP cluster nodes, not the bootstrap cluster, which uses a pre- built image (e.g., kind). NIB-prepping this image is a later step.
* D. The nkp create bootstrap command needs to be executed as root: While some commands may require elevated privileges, the NKPA course does not specify that nkp create bootstrap must be run as root. The error is more likely related to missing images in an air-gapped setup.
