Deploy a Docker Container with ECS & Fargate using Terraform

Deploy a Docker Container with AWS ECS & Fargate using Terraform

Create an ECS Cluster

Before we start

-You will need a source code editor. I prefer Visual Studio Code or AWS Cloud9, but they must have Terraform and AWS CLI installed.

-You will need to create an AWS IAM user account with admin rights, an access key, and a secret key.

-You must possess some knowledge of Terraform

For this tutorial I am using AWS Cloud9

Click here to access this project repository in GitHub.

📝Open your source code editor, create, and name your new folder.

mkdir Terraform ECS

📝Enter your created folder

cd Terraform ECS

📝Create five configuration files

touch vpc.tf providers.tf security.tf variables.tf main.tf

For this project, I chose to separate my configuration files with the following: vpc.tf, providers.tf, security.tf, variables.tf, and main.tf

Providers

By adding those two providers we can build resources from Docker & AWS

📝Copy and paste the following code into your providers.tf 👇🏽

VPC

We need a vpc and a minimum of two private subnets to build an ECS cluster

📝Copy and paste the following code into your vpc.tf 👇🏽

Security Group

📝Copy and paste the following code into your security.tf 👇🏽

Docker Image

We need an AWS ECS cluster and Fargate service in order to deploy a docker image for this project. The image being used is Centos. Also for this proj ect load balancing is False in Fargate.

📝Copy and paste the following code into your main.tf 👇🏽

Variables

Here you can define the values for all variables.

📝Copy and paste the following code into your variables.tf 👇🏽

Install the providers and run the infrastructure.

📝Run the following command

terraform init

Noticed AWS & Docker has been installed

📝Ensure that our syntax is correct with the following command:

terraform validate

📝View the layout of your infrastructure with the following command:

Terraform plan

📝Run the infrastructure with the following command:

Terraform apply --auto-approve

Auto-approve will skip the prompt to confirm installation

📝Let's check our resources

📝Now let's remove all resources with the following command.

terraform destroy

📝Type yes to confirm

Destroy complete! Resources deleted.
