Hey folks! Today, we're delving into the dynamic duo of Terraform and Docker, a powerhouse combination in the world of infrastructure automation. Strap in as we navigate through setting up Terraform scripts with Blocks and Resources, paving the way for seamless Docker integration. Let's dive right in! ๐ฅ
Task 01: Terraform Script with Blocks and Resources To kick things off, we need to acquaint Terraform with the Docker provider, specifying its source and version in our main.tf
file. Here's a snippet to get you started:
terraform {
required_providers {
docker = {
source = "kreuzwerker/docker"
version = "~> 2.21.0"
}
}
}
This provider
block sets the stage for configuring the Docker provider, acting as the conduit between Terraform and Docker.
Task 02: Creating Docker Resources Now, let's harness the power of Terraform's resource blocks to define Docker components. First up, we'll create a resource block for an Nginx Docker image:
resource "docker_image" "nginx" {
name = "nginx:latest"
keep_locally = false
}
With this resource block, we define the Nginx Docker image we want to utilize. Next, let's deploy a Docker container for Nginx:
resource "docker_container" "nginx" {
image = docker_image.nginx.latest
name = "tutorial"
ports {
internal = 80
external = 80
}
}
Here, we're instructing Terraform to spin up a Docker container named "tutorial" using the Nginx image we specified earlier. We're also mapping port 80 internally and externally for seamless access.
Pro Tip: In case Docker isn't installed, run the following commands to set it up:
sudo apt-get install docker.io
sudo docker ps
sudo chown $USER /var/run/docker.sock
And there you have it! With Terraform and Docker, the possibilities are endless. Stay tuned for more adventures in infrastructure automation! #Terraform #Docker #DevOpsJourney ๐๐ป
