In this example, you'll use Cloud Native Build (CNB) to implement infrastructure management with Terraform and Docker.

1. Basic knowledge of Terraform including concepts and commands like:
   • terraform init
   • terraform plan
   • terraform apply
   • terraform destroy
2. Use Cloud Native Build (CNB) to manage your Terraform configurations for version control and collaborative development.

The main.tf file in the root directory defines Docker container resources:

1. Pulls the nginx:latest image
2. Creates a container exposing port 8000 mapped to port 80

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

provider "docker" {}

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

resource "docker_container" "nginx" {
  image = docker_image.nginx.image_id
  name  = "tutorial"
  ports {
    internal = 80
    external = 8000
  }
}

master:
  push:
    - name: Terraform by Example
      services:
        - docker
      docker:
        image: hashicorp/terraform
      stages:
        - name: docker image ls
          script: docker image ls
        - name: docker ps
          script: docker ps
        - name: init
          script: terraform init
        - name: plan
          script: terraform plan
        - name: apply
          script: terraform apply -auto-approve
        - name: docker image ls
          script: docker image ls
        - name: docker ps
          script: docker ps

Pipeline execution results:

Create a Terraform-ready development environment with .ide/Dockerfile:

FROM hashicorp/terraform as tf

FROM node:20

# Install vscode and extensions
RUN curl -fsSL https://code-server.dev/install.sh | sh &&\
    code-server --install-extension hashicorp.terraform &&\
    echo done

COPY --from=tf /bin/terraform /usr/local/bin/terraform
