Introduction

Efficient resource management in VMware environments requires robust tools and streamlined practices. Tags are essential metadata that help categorize and organize resources like clusters, enabling administrators to maintain control over complex infrastructures. Ansible, a powerful automation tool, simplifies the process of retrieving and verifying VMware cluster tags. This article demonstrates how to automate tag verification using Ansible, with a focus on identifying and displaying the category_name and name attributes of cluster tags.

1. Why Automate VMware Tag Management?

Tags in VMware are indispensable for managing large-scale environments, providing metadata that defines a resource's purpose, ownership, or environment (e.g., production or staging). Automating tag verification ensures:

  • Consistency: Every resource adheres to predefined tagging policies.
  • Scalability: Easily manage tags across numerous clusters.
  • Efficiency: Save time and minimize human error in tag inspections.

2. Ansible: The Key to VMware Automation

Ansible provides an agentless and straightforward approach to managing VMware environments. With the community.vmware collection, administrators can seamlessly interact with VMware vCenter and automate tag-related tasks.

Installing the community.vmware Collection

Before running the playbook, install the required collection:

``bash

ansible-galaxy collection install community.vmware

3. The Playbook: Verifying category_name in VMware Cluster Tags

Below is the Ansible playbook for retrieving VMware cluster information and verifying tags for the presence of category_name:

`yaml

---

  • name: Verify category_name in VMware cluster tags

hosts: localhost

gather_facts: no

tasks:

- name: Retrieve VMware cluster information

community.vmware.vmware_cluster_info:

hostname: "{{ vcenter_hostname }}"

username: "{{ vcenter_username }}"

password: "{{ vcenter_password }}"

validate_certs: false

register: cluster_info

- name: Search and display tags with category_name

debug:

msg: >

Cluster {{ item.key }} has tag with category_name: {{ tag.category_name }} and name: {{ tag.name }}

loop: "{{ cluster_info.clusters | dict2items }}"

vars:

matching_tags: "{{ item.value.tags | selectattr('category_name', 'defined') | list }}"

when: matching_tags | length > 0

4. Understanding the Playbook

Retrieving Cluster Information

The vmware_cluster_info module collects data about clusters in your VMware environment, including tags.

Filtering Tags with category_name

Using Ansible's selectattr filter, the playbook identifies tags where the category_name attribute is defined.

Displaying Results

For each cluster, the playbook loops through matching tags and displays their category_name and name`.
