Fix Terraform Error - Azure Authorization Failed

The Error

Error: authorization failed. AuthorizationFailed: The client does not have authorization

What Causes This

The Azure service principal or user account lacks required RBAC permissions for the requested operation.

How to Fix It

Solution 1: Assign Contributor Role

az role assignment create \
  --assignee YOUR_SP_ID \
  --role "Contributor" \
  --scope "/subscriptions/YOUR_SUB_ID"

Solution 2: Create Service Principal

az ad sp create-for-rbac --name "terraform-sp" \
  --role Contributor \
  --scopes /subscriptions/YOUR_SUB_ID

export ARM_CLIENT_ID="appId"
export ARM_CLIENT_SECRET="password"
export ARM_SUBSCRIPTION_ID="sub_id"
export ARM_TENANT_ID="tenant"

Solution 3: Resource-Specific Roles

# Key Vault needs "Key Vault Administrator"
# DNS needs "DNS Zone Contributor"
az role assignment create --assignee SP_ID \
  --role "Key Vault Administrator" \
  --scope "/subscriptions/SUB_ID/resourceGroups/RG"
