🚀 Step-by-Step Guide - Terraform and Docker Installation on Amazon Linux
1️⃣ Update Your System

sudo yum update -y
2️⃣ Set Up the Hostname

sudo hostnamectl set-hostname Terraform-server
echo "Terraform-server" | sudo tee /etc/hostname
3️⃣ Install Terraform

sudo yum install -y yum-utils git
sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/Am...
sudo yum -y install terraform
terraform -v
4️⃣ Enable Terraform Autocomplete

touch ~/.bashrc
terraform -install-autocomplete
5️⃣ Install Docker
sudo yum install -y docker
sudo systemctl restart docker
sudo systemctl enable docker
sudo systemctl status docker
6️⃣ Create a Terraform Project for Docker

mkdir learn-terraform-docker-container
cd learn-terraform-docker-container
🌍 Terraform Configuration for Docker and NGINX Deployment
Create a Terraform configuration file (main.tf) to deploy NGINX on Docker:


terraform {
required_providers {
docker = {
source = "kreuzwerker/docker"
version = " 3.0.1"
}
}
}

provider "docker" {}

resource "docker_image" "nginx" {
name = "nginx"
keep_locally = false
}

resource "docker_container" "nginx" {
image = docker_image.nginx.image_id
name = "nginx-container"

ports {
internal = 80
external = 8000
}
}
💾 Save the file and proceed to the next step.

🚀 Deploying Docker Container Using Terraform
Run the following Terraform commands in your project directory:

terraform init # Initialize Terraform
terraform fmt # Format the Terraform code
terraform validate # Validate the configuration
terraform plan # Preview the changes
terraform apply # Deploy the container (Type "yes" when prompted)
🌐 Accessing the NGINX Container
After successful deployment, find the public IP of your instance:
curl ifconfig.me
🔗 Open a browser and visit:

arduino
Copy
Edit
http://your-public-ip:8000/
✅ You should see the NGINX welcome page!

🔧 Managing Docker Containers with Terraform
To check running Docker containers:


docker ps
To see all containers including stopped ones:

docker ps -a
To stop and remove all containers:

terraform destroy
🌟 Deploying Custom Docker Images with Terraform
If you have a custom Docker image hosted on Docker Hub, use the following Terraform configuration:


terraform {
required_providers {
docker = {
source = "kreuzwerker/docker"
version = " 3.0.1"
}
}
}

provider "docker" {}

resource "docker_image" "custom_image" {
name = "your-dockerhub-username/your-custom-image:latest"
keep_locally = false
}

resource "docker_container" "custom_image_container" {
image = docker_image.custom_image.image_id
name = "custom-container"

ports {
internal = 900
external = 8080
}
}
💾 Save the file and apply Terraform:

terraform init
terraform apply
🌐 Access your custom application at:

http://your-public-ip:8080/
