HelloTerraform

Welcome to the HelloTerraform repository! This repository contains simple Terraform code that demonstrates how to create Docker containers using Terraform.

Requirements

Before you start, you need to have the following:

• Terraform (version 0.12 or later)
• Docker (version 18.06.0 or later)

How to use

Clone this repository to your local machine:

git clone https://github.com/HelloDevOpsWorld/HelloTerraform.git

Change into the docker-tf or docker-custom-registry-tf directory:

cd HelloTerraform/docker-tf

or

cd HelloTerraform/docker-custom-registry-tf

Initialize Terraform by running the following command:

terraform init

Preview the changes that Terraform will make by running the following command:

terraform plan -out=plan.out

Apply the changes by running the following command:

terraform apply plan.out

This will create a Docker container based on the Nginx image and expose it on port 8080.

To remove the Docker container, simply run the following command:

terraform destroy

Explanation of the code

The Terraform code in this repository does the following:

• Sets up the required provider and version: The Docker provider is set up with version 3.0.1.
• Configures the Docker provider: The Docker provider is configured with no additional parameters in docker-tf and with docker config file in docker-custom-registry-tf .
• Creates a Docker image resource: A Docker image resource is created based on the Nginx image (version latest).
• Creates a Docker container resource: A Docker container resource is created based on the Nginx image, named "nginx," and exposed on port 8080.

Conclusion

That's it! You've successfully created a Docker container using Terraform. This code serves as a simple example of how Terraform can be used to manage Docker containers. Feel free to customize this code to meet your needs.
