You can also use - terraform show, to display created resources
and after checking the instance on aws dashboard
terraform destroy

Saving plan output. Terraform plan allows us to save output to a file
# terraform plan -out myplan-`date +'%s'`.plan

We can create different plan output for every new step added.

This will create a file with timestamp. This file can also be used to
apply.

# terraform apply myplan-date<somevalue>.plan

These plan outputs then become small steps we could apply 
to our infrastructure, incrementally and carefully.

You can use the -target flag on both the terraform
plan and terraform apply commands.

#terraform plan -target aws_eip.ourfirst
