Creating an Instance using Terraform

As we know Terraform is an Infrastructure as a code, and it is useful for automating the infrastructure.

In this article, we will learn to automate the instance using Terraform.

Procedure:

1) Write instance.tf file

Here, we are providing the configuration for the instance like in what region we want to launch the instance, here we are launching the instance in us-east-1 region

In this we have also specified the ami type, instance type, availability-zone

We have also named the key-pair name and also the security group, we have also provided the tags like Dove-Instance and Dove

When our instance would be launched the name of the instance will appear as ‘Dove-Instance’

Note: Here we have already created the security group before launching the instance, that’s why we are providing security-group-id while launching the instance

2) Launch instance using terraform commands

→ After writing the instance.tf file, now apply commands to launch the instance.

→ Apply ‘terraform init’ command

→ Then apply ‘terraform validate’ command

→ Then apply ‘terraform fmt’

→ Then apply ‘terraform plan’

→ At last execute ‘terraform apply’ command
