This repo is for devops test for OvalHR

• A dummy frontend with just a simple hello world html page using docker and nginx
• A dummy backend with no APIs and DB integrations using docker
• A mysql DB in RDS because the requirement is to use relational database and I don't know how to scale relational DB horizontally. So I did not use dockerized DB
• DB username and password passed using terraform variables but can be improved using aws secretsmanager

• Terraform (https://learn.hashicorp.com/tutorials/terraform/install-cli)
• awscliv2 (https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html)
• docker (https://docs.docker.com/engine/install/#server)

• Clone the repo
• Install above packages for your desired OS
• Create an aws IAM user with following permissions
• Set the IAM user's access key and secret access to ~/.aws/credentials as

[your-iam-profile]
aws_access_key_id = your-iam-access-key
aws_secret_access_key = your-iam-secret-access

• Add your-iam-profile to aws_profile = "your-profile" part of terraform/development/module.tf so it will be aws_profile = "your-iam-profile"
• Now go to development dir by cd terraform/development/
• Change other terraform variables if you want in module.tf file
• Run following commands sequentially

terraform init
terraform plan
terraform apply -auto-approve

• To check if frontend service is running with sample page go to Amazon Elastic Container Service -> Clusters -> <prefix>-cluster -> Services -> <prefix>-frontend-service -> Networking and click on open address at "DNS names"
• Same checking can be done with backend service. Note that backend service will show you if db connection is okay.
