Step-by-Step guide to provisioning a Docker container running an Nginx web server using Terraform:
Step 1: Install Terraform and Docker
Install Terraform on your machine by downloading the binary from the official Terraform website or using a package manager like Homebrew (for macOS) or apt-get (for Linux).
Install Docker on your machine by downloading the Docker Desktop application (for macOS or Windows) or using a package manager like apt-get (for Linux).
Step 2: Create a New Terraform Configuration File
Create a new file named in an empty directory. This file will contain your Terraform configuration.
Open the file in a text editor.
- Step 3: Specify the Docker Provider Add the following code to the main.tf file to specify the Docker provider:
terraform {
required_providers {
docker = {
source = "kreuzwerker/docker"
version = "~> 2.21.0"
}
}
}
Step 4: Configure the Docker Provider
Add the following code to the main.tf file to configure the Docker provider:
provider "docker" {}
Step 5: Pull the Nginx Docker Image
Add the following code to the main.tf file to pull the Nginx Docker image:
resource "docker_image" "nginx" {
name = "nginx:latest"
keep_locally = false
}
Step 6: Create a Docker Container
Add the following code to the main.tf file to create a Docker container from the Nginx image:
resource "docker_container" "nginx" {
image = docker_image.nginx.latest
name = "tutorial"
ports {
internal = 80
external = 80
}
}
Step 7: Initialize Terraform
Open a terminal in the directory where your main.tf file is located.
Run the command terraform init to initialize Terraform.
Step 8: Apply the Terraform Configuration
Run the command terraform apply to apply the Terraform configuration.
Review the plan and type yes to confirm.
Step 9: Verify the Docker Container
Run the command docker ps to verify that the Docker container is running.
Open a web browser and navigate to http://localhost:80 to access the Nginx web server.
Step 10: Clean Up
When you're finished, run the command terraform destroy to destroy the Docker container and image.
That's it! You've successfully provisioned a Docker container running an Nginx web server using Terraform.
