How to import existing AWS resources into Terraform? | Terraform Import existing AWS Resources

The terraform import command is used to import existing infrastructure. The command currently can only import one resource at a time. This means you can't yet point Terraform import to an entire collection of resources such as an AWS VPC and import all of it.

Let's say that you have created EC2 instances manually outside Terraform. If you like to import your EC2 instance to Terraform you can use import command and bring it under Terraform state file.

To import a resource, create a tf file first write a resource block for it in your configuration, establishing the name by which it will be known to Terraform:

resource "aws_instance" "myinstance" {
# ...instance configuration...leave this as it is
}

VERY VERY COOL! I was able to successfully import one of our critical ec2 hosts into Terraform code! Great instructions and thank you, this helped tremendously! 🙏

you could use terraform state show command to get the details from the state file and fill inside your .tf file

when you do a terraform apply after import is successful it updates the tf statefile but the instance name in the console is changes to blank, can you please let me know why is it happening

Can we import more than one resources(let's say 10 ec2) using for_each at one time?
