AWS Fargate Node App

A reference project to deploy a Node Express app onto Amazon ECS on AWS Fargate with Terraform, inspired by this tutorial documentation

A microservice which creates, and authenticates users from a MongoDB database

Pre-requisite

• Make sure you have installed Terraform, AWS CLI, and configured a default AWS CLI profile (see doc here)

terraform -help # prints Terraform options
which aws # prints /usr/local/bin/aws
aws --version # prints aws-cli/2.0.36 Python/3.7.4 Darwin/18.7.0 botocore/2.0.0
aws configure # configure your AWS CLI profile

• You have created a database on MongoDB Atlas and have obtained a database connection string

Configuration

• Create a Github project, and generate a personal access token (see doc here)

• Create an S3 bucket to store Terraform state. Populate bucket name in 01-main.tf

• Create a secret on AWS Secrets Manager named DockerHubAccessToken with key DOCKER_HUB_ACCESS_TOKEN, and your Docker access token as value

• Create a secret on AWS Secrets Manager named MongoPassword with key MONGO_PASSWORD, and your MongoDB password as value

• Populate terraform.tfvars:

default_region            = "us-east-1"
docker_username           = "matlau"
github_username           = "MatthewCYLau"
github_project_name       = "node-aws-fargate-terraform"
app_name                  = "node-aws-fargate-app"
environment               = "production"
mongo_username            = "admin-matlau"
mongo_host                = "mattewcylau-5ltcp.mongodb.net"
mongo_database_name       = "node-aws-fargate-app"

Deploy

cd deploy # change to deploy directory
terraform init # initialises Terraform
terraform apply # deploys AWS stack. See output for AWS loadbalancer DNS name
terraform destroy # destroys AWS stack

When prompted for github_token, provide the value and hit Return. Alternatively, create a local environment variable named TF_VAR_github_token

Usage

• Create a user by making POST request to /api/users with the following JSON body:

{
  "email": "jon@doe.com",
  "password": "password",
  "name": "jondoe"
}

• See Postman collection here
