AWS-EC2-Basic-Arc

Using Terraform to deploy a basic architecture for ec2 instances running apache services.

Architecture

The principal idea is to Work with Terraform and AWS to build this diagram:

Deploy the Code & Infrastructure

The procedure to deploy the infrastructure and the code need the following code:

• Create an AWS account. One option to test is to use free tier aws account.
• Install and configure aws cli
• Install and configure Terraform

Go to the environment, for this example i am using "AWS-EC2-Basic-ARC":

$ cd terraform/

$ git clone https://github.com/tinchom/AWS-EC2-Basic-Arc.git

$ cd terraform/AWS-EC2-Basic-Arc

• Initialised Terraform

$ terraform init

• Validate the configuration

$ terraform validate

• Execute the terraform plan (its going to ask you for key and secret)

$ terraform plan -out AWS-EC2-Basic-ARC.plan

• Apply the terraform plan

$ terraform apply "AWS-EC2-Basic-ARC"

If everything went right, you can view the architecture deployed on your account.

Files descriptions

• vpc.tf: This file contain the creation of VPC, Subnet, Internet GW, NAT GW, Route tables, Subnet Associations and Elastic IPs resources.
• sg.tf: This file contain the creation of Security Groups resources required for EFS connection.
• ec2.tf: This file contain the creation of EC2 resources/instances.
• vars.tf: This file contains the variables and values of access keys, secret key, subnet settings and availabilty zones. For this case is set to us-east-1a and us-east-1b.

Results

If all went well you will have 2 instances running in public and private subnets. The private will access to HTTP services running EC2 public instance.
