Terraform – writing the code and deploying our infrastructure

Now that we know which services we are going to deploy, we can make a start on our Terraform deployment. To make things more manageable, I will split our code into several files; they will be named the following:

• 001-setup.tf
• 002-resource-group.tf
• 003-networking.tf
• 004-storage.tf
• 005-database.tf
• 006-vm-admin.tf
• 007-vmss-web.tf
• 098-outputs.tf
• 099-variables.tf
• vm-cloud-init-admin.yml.tftpl
• vmss-cloud-init-web.tftpl

I have done this to more logically group all the functions around a certain part of the deployment code together; for example, all of the networking elements can be found in the 003-networking.tf file and the variables used in the 099-variables.tf file.

Information

As mentioned at the start of this chapter, what follows is not 100% of the code contained within each of the files, and I will be referencing blocks out of the variables file in line...
