Automating Infrastructure Deployment for Static Websites with Terraform in AWS
We'll leverage Terraform, an infrastructure as code (IaC) tool, to orchestrate the process. Here's a breakdown of the key steps involved:
1. Terraform Setup:
Ensure Terraform is installed and configured locally.
2. Configuring the AWS Provider:
Terraform requires an AWS provider configuration file specifying the region and credentials for provisioning resources. We will create a provider.tf file for this.
3. Defining the VPC Network:
We'll define the Virtual Private Cloud (VPC)in the vpc.tf file where the server on the EC2 instance will reside. This includes creating a public subnet for internet access.
Creating Internet Connectivity and Security:
An internet gateway is established (in network.tf) to enable internet access for the VPC. We'll also define a custom route table and associate it with the public subnet for proper routing. Finally, a security group is created to control inbound and outbound traffic for the Jenkins EC2 instance.
4. Building the Terraform Configuration:
The core Terraform configuration file (main.tf) defines the provisioning of our EC2 instance with through a user data script. Additionally, it creates an S3 bucket for hosting the static website and configures it for website hosting.
5. Terraform Workflow:
Once the configuration is complete, we'll use Terraform commands to initialize, plan, and apply the changes. This will provision the resources in our AWS environment.
terraform init
terraform plan
terraform apply
6. Validating Resources (Optional):
You can now validate the created AWS resources like the EC2 instance, security group, VPC, and S3 bucket to ensure everything is set up correctly.
