# Terraform AWS Learning Project
## Description
This repository is dedicated to learning Terraform and exploring its capabilities in managing AWS resources. The project focuses on provisioning and configuring AWS services such as S3, VPC, security groups, EC2 instances, and utilizing Terraform function expressions to optimize and manage infrastructure as code.

## Prerequisites
Before you begin, ensure you have the following installed:
- [Terraform](https://www.terraform.io/downloads.html) (version 1.x or higher)
- [AWS CLI](https://aws.amazon.com/cli/) configured with your AWS credentials
- Access to an AWS account
## Getting Started
To get started with this project:
1. Clone the repository:
```bash
git clone https://github.com/yourusername/terraform-aws-learning.git
cd terraform-aws-learning
```
2. Initialize Terraform:
```bash
terraform init
```
3. Validate the configuration files:
```bash
terraform validate
```
4. Plan the changes to be made:
```bash
terraform plan
```
5. Apply the changes to provision the resources:
```bash
terraform apply
```
## AWS Resources
### S3
This project includes an S3 bucket for storing files and data.
```hcl
resource "aws_s3_bucket" "my_bucket" {
bucket = "my-unique-bucket-name"
acl = "private"
}
```
### VPC
A Virtual Private Cloud (VPC) is created to isolate the resources.
```hcl
resource "aws_vpc" "my_vpc" {
cidr_block = "10.0.0.0/16"
enable_dns_support = true
enable_dns_hostnames = true
tags = {
Name = "my_vpc"
}
}
```
### Security Groups
Security groups are defined to control inbound and outbound traffic for EC2 instances.
```hcl
resource "aws_security_group" "my_security_group" {
name = "my_security_group"
vpc_id = aws_vpc.my_vpc.id
ingress {
from_port = 22
to_port = 22
protocol = "tcp"
cidr_blocks = ["0.0.0.0/0"]
}
egress {
from_port = 0
to_port = 0
protocol = "-1"
cidr_blocks = ["0.0.0.0/0"]
}
}
```
### EC2 Instances
EC2 instances are launched within the defined VPC and security group.
```hcl
resource "aws_instance" "my_instance" {
ami = "ami-0c55b159cbfafe01e" # Replace with a valid AMI ID
instance_type = "t2.micro"
subnet_id = aws_subnet.my_subnet.id
vpc_security_group_ids = [aws_security_group.my_security_group.id]
tags = {
Name = "my_instance"
}
}
```
## Terraform Function Expressions
Terraform function expressions are used to manipulate and transform data within configurations. Here are a few examples:
- **Joining a List**:
```hcl
variable "tags" {
type = list(string)
default = ["Environment=Dev", "Project=Learning"]
}
output "tag_string" {
value = join(", ", var.tags)
}
```
- **Conditional Expressions**:
```hcl
resource "aws_instance" "my_instance" {
ami = var.instance_type == "t2.micro" ? "ami-0c55b159cbfafe01e" : "ami-abc123"
instance_type = var.instance_type
}
```
## Usage
To modify or add resources:
1. Update the respective `.tf` files in the repository.
2. Re-run `terraform plan` to see the changes.
3. Apply the changes using `terraform apply`.
## Contributing
Contributions are welcome! To contribute to this project:
1. Fork the repository.
2. Create a new branch:
```bash
git checkout -b feature/your-feature
```
3. Make your changes and commit them:
```bash
git commit -m "Add some feature"
```
4. Push to the branch:
```bash
git push origin feature/your-feature
```
5. Open a pull request.
