Demo create server EC2

In this tutorial, I will create simple and practical example of how to provision EC2 instance with Github Actions and Terraform. I will use workflow_dispatch type of workflow which is triggered manually by user, using Terraform Github action from HashiCorp.

Goal

Deploy EC2 instance of t3.small size to your AWS account using Github Actions and Terraform.

I will use ‘workflow_dispatch’ event for this, which is manually triggered.

workflow_dispatch

This event occurs when someone triggers a workflow run on GitHub or sends a POST request to the "Create a workflow dispatch event" endpoint. For more information, see "Events that trigger workflows."

Dependencies

ADD secrets github AWS user key AWS user secret

Overview of terraform script to provision EC2 instance

  • The provisioned instance based on ubuntu AMI.
  • Instance type selected by default is t3.micro.
  • Instance will be provisioned to default VPC | subnet | security group.
  • Need to create SSH key pair to connect with provisioned instance.
  • EC2 will be provisioned select by default ‘us-east-1’ region.

Try to connect

Now try to connect to this instance using ‘ssh-key’

I downloaded ssh-key.pem file

chmod 600 ssh-key.pem
ssh -i ssh-key.pem ubuntu@<IP Public>
uname -a

Success!
