Greeting App for AWS

Personal test for an AWS "micro-services" stack with terraform, rails, go and redis.

The app consists in a form where you put your name. It will then fetch a message to display for greeting you. The app will also records how many time your name has been greeted.

• api: contains the go api that creates the messages
• dev: contains files to run the stack in local
• metadatastore: contains the rails api to communicate with the redis instance that records how many time your name has been entered
• stack: contains the terraform code to deploy the stack on aws
• ui: contains the code for the front-end (vanilla js)

How to run the stack locally?

Run docker-compose up then go to http://localhost:8080.

How to run the stack on AWS?

Rename terraform.tfvars.example to terraform.tfvars and fill the variables.

Run terraform plan to check that everything is ok. If all is ok run terraform apply to setup the stack.

The stack is composed of:

• a VPC
• 2 public subnets (used by the alb)
• 2 private subnets (used by fargate)
• a fargate cluster (with services and repositories for the api and the metadatastore)
• 1 bucket s3 (for the ui)
• 1 ALB (it serves the same purpose than nginx in local)
• 1 redis cluster

When the infrastructure is setup, you have to deploy the code.
