terraform-azurerm-key-vault-tfvars

This module creates and manages an Azure Key Vault and stores your Terraform variable files as Secrets within it.

Usage

Example module usage:

module "azure_key_vault_tfvars" {
  source = "github.com/DFE-Digital/terraform-azurerm-key-vault-tfvars?ref=v0.5.1"

  environment                = "Dev"
  project_name               = "myproject"
  existing_resource_group    = "my-rg-name"
  enable_resource_group_lock =  false
  azure_location             = "uk-south"

  # (legacy) Grant access to Key Vault using Access Policy
  # key_vault_access_users = [
  #   "my_email.address.suffix#EXT#@platformidentity.onmicrosoft.com",
  # ]

  # (Preferred) Leverage Azure RBAC to grant access to Key Vault
  key_vault_access_use_rbac_authorization = true

  # List of IPV4 Addresses that are permitted to access the Key Vault
  key_vault_access_ipv4 = [
    "8.8.8.8"
  ]

  ## Specify a list of Azure Subnet Resource IDs that can access this Key Vault
  # key_vault_access_subnet_ids = [
  #   "/my/azure/subnet/id"
  # ]

  tfvars_filename     = "dev.tfvars"
  secret_expiry_years = 5

  # enable_diagnostic_setting             = true
  # enable_log_analytics_workspace        = false
  # diagnostic_log_analytics_workspace_id = "my-log-analytics"
  # diagnostic_eventhub_name              = "my-eventhub-name"
  # enable_diagnostic_storage_account     = false
  # diagnostic_storage_account_id         = "my-storage-account-id"

  tags = {
    "My Tag" = "My Value!"
  }
}
