Deploying Nginx with Terraform using the Docker Provider

How to deploy an Nginx web server to a Docker provider using Terraform.

Introduction

The Terraform code you’ve provided is a configuration script for managing infrastructure using Terraform, specifically focused on deploying a Docker container. Let’s break down the components of this script:

Terraform Configuration

1. Required Providers:

required_providers {
  docker = {
    source  = "kreuzwerker/docker"
    version = "~> 3.0.1"
  }
}

• This block declares the necessary provider(s) for Terraform to use. Here, it specifies the Docker provider.
• source: Indicates the source of the provider. Here, "kreuzwerker/docker" is the source, which is a Terraform provider for Docker.
• version: Specifies the version of the Docker provider. "~> 3.0.1" means any version compatible with 3.0.1.

2. Provider Configuration:

provider "docker" {}

• This block configures the Docker provider. In this case, it’s an empty configuration, which means it will use default settings.
