In this example, you'll use Cloud Native Build (CNB) to implement infrastructure management with Terraform and Docker.
- Basic knowledge of Terraform including concepts and commands like:
terraform initterraform planterraform applyterraform destroy
- 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:
- Pulls the
nginx:latestimage - 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
}
}
