Modifying Infrastructure With Terraform | Terraform Tutorial | #4
Modifying infrastructure in Terraform is as simple as changing values in our configuration files and applying the changes. Examples of what you might modify could be adding tags to an existing resource, updating DNS entries, updating ingress/egress security group rules and more. All resources can be modified and Terraform will handle any needs to shutdown, restart and/or re-create any resources if needed.
In this video we'll update the configuration of the original AWS EC2 instance that we created in the previous video. Below is an overview of what we'll be doing.
