vSphere tags are a powerful feature in VMware vCenter that allows you to add attributes to virtual machines (VMs) for categorization and filtering. These tags can be used to dynamically include or exclude VMs from backup and replication jobs, making it easier to manage your virtual infrastructure. In this blog post, we will explore how to use Terraform to assign vSphere tags to VMs during deployment, and how Veeam supports the use of these tags in their backup and replication jobs.
Using Terraform to Assign vSphere Tags
—————————————-
Terraform is a popular tool for deploying infrastructure in a repeatable, declarative way. It allows you to define your infrastructure as code, and then apply that code to create and manage your virtual infrastructure. By using Terraform to assign vSphere tags to VMs during deployment, you can ensure that your backup and replication jobs are always up-to-date with the current state of your virtual infrastructure.
To use Terraform to assign vSphere tags to VMs, you will need to create two data sources in your Terraform code: one for the vCenter server and one for the vSphere tags. You can then use these data sources to reference the tags in your VM deployments.
For example, here is some sample Terraform code that creates a VM with a specific tag:
“`
# Configure the vCenter server data source
data “vmware_vcenter” “example” {
hostname = “vcserver.example.com”
username = “admin”
password = “secret”
}
# Create a tag category for backup/replication
resource “vmware_tag_category” “example” {
name = “Backup/Replication”
description = “Tag category for backup and replication”
}
# Create a tag for inclusion in the backup job
resource “vmware_tag” “example” {
name = “TPM03-NO-BACKUP”
description = “Tag for excluding VMs from backup jobs”
category_id = vmware_tag_category.example.id
}
# Create a VM with the tag assigned
resource “vmware_virtual_machine” “example” {
name = “my-vm”
datacenter_id = data.vmware_vcenter.example.datacenter_id
folder_id = data.vmware_vcenter.example.folder_id
resource_pool_id = data.vmware_vcenter.example.resource_pool_id
network_id = data.vmware_vcenter.example.network_id
disk_count = 2
# Assign the tag to the VM
tags = [
vmware_tag.example,
]
}
“`
In this example, we create a tag category for backup and replication, and then create a tag that is included in the backup job. We then create a VM with the tag assigned to it.
Using Veeam with vSphere Tags
——————————
Veeam supports the use of vSphere tags in their backup and replication jobs, allowing you to dynamically include or exclude VMs from these jobs based on their attributes. To configure Veeam to use vSphere tags, you will need to set up a backup job that references the tags.
For example, here is some sample Veeam code that configures a backup job to include all VMs with the tag “TPM03-NO-BACKUP”:
“`
# Configure the backup job
Backup Job {
Name = “My Backup Job”
Description = “Backs up my VMs”
# Include all VMs with the TPM03-NO-BACKUP tag
Include = [
“SELECT * FROM VM WHERE Tag = ‘TPM03-NO-BACKUP'”,
]
# Exclude all other VMs
Exclude = [
“SELECT * FROM VM WHERE Tag != ‘TPM03-NO-BACKUP'”,
]
}
“`
In this example, we configure a backup job to include all VMs with the tag “TPM03-NO-BACKUP” and exclude all other VMs.
Benefits of Using vSphere Tags with Terraform and Veeam
——————————————————–
Using vSphere tags with Terraform and Veeam offers several benefits for managing your virtual infrastructure:
* **Dynamic Inclusion/Exclusion**: With vSphere tags, you can dynamically include or exclude VMs from backup and replication jobs based on their attributes. This allows you to easily manage your virtual infrastructure as it changes over time.
* **Repeatable, Declarative Deployments**: Terraform allows you to define your infrastructure as code, making it easy to repeatably deploy and manage your virtual infrastructure.
* **Up-to-Date Backup Jobs**: By using vSphere tags in your backup jobs, you can ensure that your backup jobs are always up-to-date with the current state of your virtual infrastructure.
Conclusion
———-
In conclusion, using vSphere tags with Terraform and Veeam offers a powerful solution for managing your virtual infrastructure. By assigning vSphere tags to VMs during deployment using Terraform, and then referencing these tags in your backup jobs using Veeam, you can ensure that your backup jobs are always up-to-date with the current state of your virtual infrastructure. This approach offers several benefits, including dynamic inclusion/exclusion, repeatable, declarative deployments, and up-to-date backup jobs.
