| To deploy the vCenter Server in our nested home labs and we want to deploy these lab instances multiple times we need to pre-install and pre-configure the vCenter server a little bit.
| | == Summary == |
| When we have a fully installed vCenter Server instance we can clone this in each lab instance that we create.
| | Uplaoding files from nsx.ninja and iwan.wiki |
| In this article: [http://www.iwan.wiki/The_nested_labs_project_overview/introduction The nested labs' project overview/introduction] I explain how many lab instances I can create (or replicate).
| |
| | |
| There are plenty of blog articles on how to deploy a vCenter Server and there are a few ways to do this.
| |
| I use the CLI deployment where we have to use a.JSON file with input parameters to deploy the full vCenter Server.
| |
| I learned this a few years ago from my colleague Wesley van Ede.
| |
| | |
| So before I started the deploy I prepared the .JSON file:

| Other prerequisites that need to be in place are:
| |
| * Create “L1-APP-MGMT11” NSX-T Segment on NSX-T infra
| |
| * Clone the control server VM and make sure a new DNS zone “lab1.local” on the DNS server
| |
| * Created new A record for new VCSA deployment on the control server
| |
| | |
| NOTE: Before deploying the vCenter Server (template) the Control Server needs to be online and the DNS + DNS records need to be configured because the vCenter Server needs this for the initial deployment. When the install is done you can turn it off for the full lab deployment (clone) later.
| |
| | |
| This installation is done using the CLI deployment tool using the command:
| |
| | |
| {{console|body=
| |
| E:\vcsa-cli-installer\win32>vcsa-deploy.exe install C:\Scripts\PowerCLI\Terraform\VCSA\vcsatemplate.json —accept-eula —no-ssl-certificate-verification
| |
| }}
| |
| | |
| After deployment, I turned off the VCSA and downgraded the memory from 16 GB to 8 GB.
| |
| | |
| Now that the vCenter Server (template) is fully installed we are ready to clone it with Terraform.
| |
| The scripts for cloning the vCenter Server can be found below:

| So we are ready to execute the terraform code on a per-directory basis.
| |
| | |
| Validate your code:
| |
| {{console|body=
| |
| ihoogendoor-a01:#Test iwanhoogendoorn$ tfenv use 0.11.14
| |
| [INFO] Switching to v0.11.14
| |
| [INFO] Switching completed
| |
| ihoogendoor-a01:Test iwanhoogendoorn$ terraform validate
| |
| }}
| |
| | |
| Plan your code:
| |
| {{console|body=
| |
| ihoogendoor-a01:Test iwanhoogendoorn$ terraform plan
| |
| }}
| |
| | |
| Execute your code to implement the Segments:
| |
| {{console|body=
| |
| ihoogendoor-a01:Test iwanhoogendoorn$ terraform apply
| |
| }}
| |
| | |
| When the segments need to be removed again you can revert the implementation:
| |
| {{console|body=
| |
| ihoogendoor-a01:Test iwanhoogendoorn$ terraform destroy
| |
| }}
