In this example, the instance_name variable is defined with a type of string, and it is given a default value of "my-instance". The AWS provider is then configured to use the us-west-2 region.

The aws_instance resource is used to launch Amazon EC2 instances. The tags argument is used to assign a name tag to the instance, and it is set to the value of the instance_name variable.

You can change the value of instance_name by modifying the default value in the variable definition, or you can specify a different value when you run Terraform by using the -var flag. For example, if you want to launch an instance with the name "my-other-instance", you can run the following command:

$ terraform apply -var ‘instance_name=”my-other-instance”‘
