Resource Addressing and Resource Parameters to Connect Resources
Explore how to use resource addressing and parameters to connect resources within Terraform configurations. Understand referencing attributes, managing multiple resource instances, and handling complex data types for accurate and interconnected infrastructure setups.
We'll cover the following...
Resource addressing
The resources we create in our Terraform configuration will often be related. For instance, creating a web application that runs on virtual machines might involve a virtual network, virtual machines, network interfaces, firewall rules, and a load balancer. All these resources will refer to each other for their configuration. The load balancer will need to reference the network interfaces on the virtual machines, and the network interfaces will need to reference a subnet on the virtual network. Resource addressing is how we can reference the attributes of a resource within our Terraform configuration.
