Infrastructure Requirements
The following Nutanix environment components are required.
| Component | Version or Type | Purpose |
|---|---|---|
| Nutanix AHV | 10.0.1.1 or later | Hypervisor for VM workloads |
| Nutanix AOS | 7.3.0.5 or later | Nutanix operating system |
| Prism Central | Deployed and accessible | Centralized management console for Nutanix environments |
| Network Access | Prism Central accessible via HTTPS (port 9440) | API connectivity to Prism Central |
| Credentials | Admin user credentials | API access |
The following Nutanix environment components are required.
| Component | Version or Type | Purpose |
|---|---|---|
| Apstra | 6.0 or 6.1 | Data center fabric management |
| Day-0 Onboarding | Devices are discovered and blueprints are created. | Devices are onboarded |
| Network Access | Apstra server accessible via HTTPS (port 443) | Access the Apstra server |
| Credentials | Admin user credentials | API access |
| Blueprints | At least one blueprint configured and committed | Required for automation |
| Component | Version or Type | Purpose |
|---|---|---|
| Kubernetes | 1.31 or later | Container orchestration platform |
| Cluster Type | Single-node or multi-mode (both are supported) | Type of cluster |
| kubectl | Connected and configured to cluster per Kubernetes 1.31 or later | Command-line tool for communicating with a Kubernetes cluster's control plane |
| Storage | Persistent volume support (local-path, NFS, or other) | Persistent data storage |
| Helm | 3.0 or later | Package manager for Kubernetes |
| Resources | Minimum of 4 CPU cores, 8GB RAM, and 50GB storage | System Requirements |
| CPU Architecture | x86-64-v2 or newer | Required by AWX's PostgreSQL 15 container |
QEMU/KVM VMs with CPU model "qemu64" or "QEMU Virtual CPU v2.5+" will fail at the
PostgreSQL pod start-up with this error: "Fatal glibc error: CPU does not support
x86-64-v2". Fix this in your hypervisor: set CPU model to "host" (pass-through)
or at minimum "Skylake-Client" before deploying.
Verify that the CPU architecture support with the following command:
grep -m1 flags /proc/cpuinfo | tr ' ' '\n' | grep -E 'sse4_1|sse4_2|ssse3|popcnt' #
All four flags must appear in the output.
If you need to create a new Kubernetes cluster using the automated script, the following components are required.
| Component | Version or Type | Purpose |
|---|---|---|
| Linux Server | Ubuntu 20.04 or later, CentOS 8 or later, or RHEL 8 or later | Required for Kubernetes cluster |
| Resources | Minimum 2 CPU cores, 4GB RAM, and 20GB storage | Install Kubernetes |
| Root/Sudo Access | N/A | Required for Kubernetes installation |
| Python | 3.10 or later (script is installed if it isn't already) | Required to execute installed scripts |
| Internet Access | Minimum 4 CPU cores, 8GB RAM, 50GB storage | Required to download Kubernetes components |
| CPU Architecture | x86-64-v2 or newer | Same requirement as existing Kubernetes cluster in Table 3. |
Network Connectivity Requirements
The following components must have network connectivity:
-
Kubernetes Cluster ←→ Nutanix Prism Central (port 9440)
-
Kubernetes Cluster ←→ Apstra Server (port 443)
-
Event Service <-> AWX (via NodePort)
-
AWX <-> Apstra Server (port 443)
Software Requirements on Deployment Host
For existing Kubernetes users, the following software is required:
-
Git — Used to clone repositories
-
kubectl — Kubernetes command-line tool (configured)
-
Helm — Package manager for Kubernetes v3.0 and later
-
Docker — Required to load the Nutanix plugin image. Install with: sudo apt-get install -y docker.io, then add your user to the docker group: sudo usermod -aG docker $USER (re-login required)
-
Bash — Shell environment for running script
For new Kubernetes installations, the following software is required:
The k8s_deploy.sh script will automatically install kubectl, Helm, and Docker.
-
Git — Used to clone repositories
-
Sudo Access — Required for Kubernetes installation
-
Internet Access — Required to download components
-
Bash — Shell environment for running scripts
-
Python 3.10 or later — Script will install if missing
Required Credentials
You need to create the following credentials:
-
Nutanix Prism Central
-
Username/password with admin privileges
-
Apstra
Username/password combination with admin privileges
-
