Introduction

Nutanix and Ansible are a natural fit for enterprise automation. While Nutanix provides powerful APIs and CLI tools, Ansible brings repeatable, version-controlled orchestration to the datacenter. This guide helps you install, authenticate, and run your first playbook using the official Nutanix Ansible collection.

Nutanix Repository on GitHub

Step 1: Prerequisites

Before starting, ensure:

• Python 3.8+ is installed
• pip is available
• Ansible 2.11+ is installed
• You have access to Prism Central or Prism Element

Install Ansible:

pip install ansible

Step 2: Install the Nutanix Ansible Collection

Install from Ansible Galaxy:

ansible-galaxy collection install nutanix.ncp

Verify:

ansible-galaxy collection list | grep nutanix

Step 3: Define Your Inventory

Create inventory.yml:

all:
  hosts:
    localhost:
      ansible_connection: local

This setup runs tasks from the Ansible control machine, ideal for calling remote Nutanix APIs.

Step 4: Store Your Credentials

Create nutanix_credentials.yml and encrypt with ansible-vault:

nutanix_pc_hostname: "prism.example.com"
nutanix_pc_port: 9440
nutanix_username: "admin"
nutanix_password: "S3cure!"
validate_certs: false

Encrypt:

ansible-vault encrypt nutanix_credentials.yml

Step 5: Write Your First Playbook

Create create_vm.yml:

- name: Create a VM in Nutanix
  hosts: localhost
  collections:
    - nutanix.ncp
  vars_files:
    - nutanix_credentials.yml
  tasks:
    - name: Launch a test VM
      nutanix.ncp.vms:
        state: present
        name: "demo-vm"
        cluster_name: "prod-cluster"
        memory_size_mib: 2048
        num_vcpus_per_socket: 1
        num_sockets: 2
        boot_type: UEFI
        vm_disks:
          - disk_size_mib: 10240
            storage_container: "default-container"
        vm_nics:
          - subnet_name: "vlan10"

Step 6: Run the Playbook

ansible-playbook create_vm.yml --ask-vault-pass -i inventory.yml

You’ll be prompted for your Ansible Vault password.

Summary

You’re now equipped with a working Ansible setup for Nutanix! You installed the Nutanix collection, secured credentials, and launched a VM via a declarative YAML playbook. In upcoming posts, we’ll explore how to expand, delete, snapshot, and audit Nutanix resources using the same model.
