- Enabled Terraform recommended preset - Added rules for documentation, naming conventions, and unused declarations - Note: No TFLint plugins available for vsphere or vault providers - Core Terraform ruleset will still catch syntax errors and best practices
Terraform vSphere Resource Groups Module
This Terraform module manages vSphere resource pools (resource groups) with CPU/memory allocation controls and integrated tagging for organization and management.
Purpose
Creates and manages vSphere resource pools with configurable resource allocation policies, reservations, limits, and shares. Includes automated tagging for environment and resource group classification.
What It Does
- Creates resource pools under vSphere cluster
- Configures CPU reservations, limits, and shares
- Configures memory reservations, limits, and shares
- Creates tag categories for Environment and ResourceGroupType
- Applies tags to resource pools for organization
Usage
module "vsphere_resource_groups" {
source = "./terraform-vsphere-resourcegroups"
datacenter = "DC1"
cluster_name = "Cluster01"
environment = "prod"
role_id = var.vault_role_id
secret_id = var.vault_secret_id
resource_groups = {
kubernetes = {
name = "Kubernetes"
cpu_reservation = 4000
cpu_shares = "high"
memory_reservation = 8192
memory_shares = "high"
}
docker = {
name = "Docker"
cpu_shares = "normal"
memory_shares = "normal"
}
infra = {
name = "Infrastructure"
cpu_shares = "low"
memory_shares = "low"
}
}
}
Key Features
- Resource Allocation: CPU and memory reservations, limits, shares
- Shares Mapping: Automatic conversion of low/normal/high to vSphere values (500/1000/2000)
- Tagging System: Environment and resource group type tags
- Flexible Configuration: Optional parameters with sensible defaults
- Expandable Resources: Allow resources to grow beyond reservations
Default Resource Groups
- Kubernetes: For Kubernetes infrastructure
- Docker: For Docker containers
- Infra: For infrastructure services
Prerequisites
- VMware vSphere with compute cluster
- Vault with vSphere credentials
- Terraform >= 0.13
