Understanding Terraform Resources
A resource in Terraform represents a component of your infrastructure, such as a physical server, a virtual machine, a DNS record, or an S3 bucket. Resources have attributes that define their properties and behaviours, such as the size and location of a virtual machine or the domain name of a DNS record.
When you define a resource in Terraform, you specify the type of resource, a unique name for the resource, and the attributes that define the resource. Terraform uses the resource block to define resources in your Terraform configuration.
Our main.tf file
Now initialize using terraform init command
Now run terraform apply command
add the below code to your existing main.tf file
resource "aws_instance" "web_server" {
ami = "ami-0c3ee0b890421ff63" #give ur AMi
instance_type = "t2.micro"
key_name = "sfgc-jenkins-key" #give ur keyname
security_groups = [
aws_security_group.web_server.name
]
user_data = <<-EOF
#!/bin/bash
echo "<html><body><h1>Hare Krishna<br>Welcome to my website!</h1></body></html>" > index.html
nohup python -m SimpleHTTPServer 80 &
EOF
}
so our main.tf file looks something like this...
Now run terraform init and terraform apply commands.
terraform apply, command will launch the EC2 instance
Open your AWS console, and check the running instance created by your file : )
