Linux VM Scale Set

This template deploys a desired count Linux VM Scale Set. Once the VMSS is deployed, the user can deploy an application inside each of the VMs (either by directly logging into the VMs or via a remote-exec provisioner).

main.tf

The main.tf file contains the actual resources that will be deployed. It also contains the Azure Resource Group definition and any defined variables.

outputs.tf

This data is outputted when terraform apply is called, and can be queried using the terraform output command.

provider.tf

You may leave the provider block in the main.tf, as it is in this template, or you can create a file called provider.tf and add it to your .gitignore file.

Azure requires that an application is added to Azure Active Directory to generate the client_id, client_secret, and tenant_id needed by Terraform (subscription_id can be recovered from your Azure account details). Please go here for full instructions on how to create this to populate your provider.tf file.

terraform.tfvars

If a terraform.tfvars or any .auto.tfvars files are present in the current directory, Terraform automatically loads them to populate variables. We don't recommend saving usernames and password to version control, but you can create a local secret variables file and use the -var-file flag or the .auto.tfvars extension to load it.

variables.tf

The variables.tf file contains all of the input parameters that the user can specify when deploying this Terraform template.
