VMware Tag Verification with Ansible

Managing tags in VMware environments can become complex without automation. In this article, you will learn how to verify the existence of VMware tags and create them when necessary using the community.vmware collection.

Why Use Ansible for VMware Tag Management?

Ansible simplifies tag management in VMware, offering a streamlined way to ensure tags are consistently applied across your infrastructure. The vmware_tag module is part of the community.vmware collection, providing robust support for tag operations.

Playbook to Verify VMware Tags

Here’s an example playbook for verifying and creating tags:

- name: Verify VMware tags
  hosts: localhost
  gather_facts: no
  tasks:
    - name: Ensure the VMware tag exists
      community.vmware.vmware_tag:
        hostname: "{{ vcenter_hostname }}"
        username: "{{ vcenter_username }}"
        password: "{{ vcenter_password }}"
        validate_certs: no
        category_name: "{{ category_name }}"
        tag_name: "{{ tag_name }}"
        description: "Tag created by Ansible"
        state: present

Variables Explained

• vcenter_hostname: The VMware vCenter server address.
• vcenter_username: Username for authentication.
• vcenter_password: Password for vCenter access.
• category_name: The category under which the tag is created or verified.
• tag_name: The name of the tag to verify or create.
• state: present: Ensures the tag exists.

How It Works

1. Check for Tag Existence: If the specified tag exists, the playbook does nothing.
2. Create the Tag if Missing: If the tag doesn’t exist, the playbook creates it in the specified category.

Prerequisites

1. Install the community.vmware collection:

   ansible-galaxy collection install community.vmware
   

2. Ensure pyvmomi is installed on the control node:

   pip install pyvmomi
   

3. Secure your credentials using Ansible Vault:

   ansible-vault encrypt_string 'your_password_here' --name 'vcenter_password'
   

4. Verify your setup:

   ansible localhost -m community.vmware.vmware_about_info -a "hostname='your_vcenter'"
   

Benefits of Automating VMware Tags with Ansible

• Consistency: Ensure that tags are applied uniformly across resources.
• Efficiency: Save time with automation rather than manual tagging.
• Scalability: Manage tags across multiple VMs and datastores effortlessly.

Conclusion

Using Ansible for VMware tag management enables efficient, consistent, and scalable operations. Whether you are organizing virtual machines or tracking resources, tags simplify infrastructure management.
