vDefend Form-Driven Blueprint (VCF Automation 9)

This package contains:

• blueprints/vdefend-form-driven.yaml — Cloud Template that calls Terraform to create vDefend groups/services/rules.
• blueprints/forms/vdefend-form.json — Custom Form draft that pulls vCenter VMs via ABX and parses CSV ports.
• ABX actions:
  • list_vcenter_vms — exposes vCenter inventory for the form.
  • apply_nsx_tags_for_tiers — tags selected VMs with tier and env.
  • send_email — generic SMTP mailer.

Wiring overview

1. Create ABX actions (Python 3):

   • list_vcenter_vms: set constants VCENTER_SERVER, VCENTER_USERNAME, VCENTER_PASSWORD.
   • apply_nsx_tags_for_tiers: none (reads blueprint inputs).
   • send_email: set constants SMTP_HOST (and optionally user/pass).

2. Import the Terraform module (re-use the vdefend_baseline_module from the previous kit, or point the blueprint to your Git path).

3. Create the Cloud Template from vdefend-form-driven.yaml. Map nsx_* inputs to Project Secrets.

4. Attach Custom Form:

   • Import vdefend-form.json into the Form Designer for this template.
   • Change the data source actionId on vm_web, vm_app, vm_db to the actual ABX ID of list_vcenter_vms.

5. Event Subscriptions:

   • Create a subscription: Event = Deployment Completed, Filter by blueprint name = vdefend-form-driven.
   • Add two actions in order:
     1. apply_nsx_tags_for_tiers — Map inputs from the deployment inputs (vm_web, vm_app, vm_db, env_value, nsx_manager_url, nsx_username, nsx_password).
     2. send_email — Build body and to_email using deployment inputs/outputs:
        • to_email = requester_email
        • subject = "vDefend policy created: " + app_name
        • body example:

          Application: ${app_name}
          Environment: ${env_value}
          
          NSX Section: ${outputs.sectionPath}
          Groups:
            Web: ${outputs.groups.web}
            App: ${outputs.groups.app}
            DB : ${outputs.groups.db}
          
          Ports:
            Web->App: ${inputs.ports_web_to_app}
            App->DB : ${inputs.ports_app_to_db}
          

Notes

• The policy is tag-driven. After deployment, the ABX action tags your selected VMs: {tier:web|app|db} and {env:<value>}. The groups in NSX will immediately include them.
• To extend rules, add more arrays (e.g., ports_web_to_db) and mirror them in the Terraform module.
• For strict change control, protect the section with a lock or maintain via GitOps-only.
