Cloud: Terraform, Cloudformation (Home Lab)

 Create an EC2 instance by terraform code

-Create an ubuntu ec2 machine wherein I will install terraform to perform the tasks in the cloud

- Download terraform

sudo su

wget -O- https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg

echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list

sudo apt update && sudo apt install terraform

Lets now create  a directory inside the machine where we will write terraform scripts

# mkdir terraform 

# cd terraform

Generate an access key and secret key

Documentation : https://registry.terraform.io/providers/hashicorp/aws/latest/docs

nano connection.tf 

(remember that all the terraform scripts ends with .tf) 

Press x > y > enter

now, write the code to create ec2 instance via terraform

resource "aws_instance" "web" {
  ami           = data.aws_ami.ubuntu.id
  instance_type = "t3.micro"

  tags = {
    Name = "HelloWorld"
  }

##now we have written two terraform files (tf). Execute them.

terraform init

terraform apply --auto-approve
