In our last couple of posts on Building Infrastructure and modify we created a resource group within Azure and then modified the tags. Having a single resource group is not going to add value to any organization, we need to create infrastructure within the resource group. In an upcoming post, we will create a virtual machine (VM) but before a VM is created some exiting infrastructure needs to be in place.
Below the minimum set of resources that need to in place before a VM can be created:
- Resource group
- Virtual network
- Subnet
- Network security group
- Network interface
Let’s start with adding a Virtual network to our code
# Create a virtual network
resource "azurerm_virtual_network" "virtual_network" {
name = "Vnet"
address_space = "10.0.0.0/16"
location = "eastus"
resource_group_name = azurerm_resource_group.rsg.name
}To create the virtual network (VNet) it is dependant on a resource group. We need to specify the resource group that it will be associated with. The value resource_group_name uses an expression azurerm_resource_group.rsg.name, this gives the name of the resource group that is referenced by azurerm_resource_group resource with the name rsg. In general, the syntax of an expression is type.name.attribute.
