I chose to use App Runner, as the request was a simple environment. I could have launched an ec2 within the VPC, but would have needed to script the instance to run the containers, add ELB, etc. App Runner handles this for me, with the main drawback that it doesn't run in a VPC, which made exposing the DB to the world necessary.

Normally I would NEVER do this, but to keep things simple, I went with this approach.

With this repo we are creating a VPC, with 2 subnets which are attached to an internet gateway and NAT gateway. We then create an RDS postgresql database which is public facing, as amazon's app runner service doesn't run within a VPC.

We then create a container registry (ECR), since app runner cannot interface with other registries at this time. Once that's created, we log into the registry with docker, then pull the image from dockerhub, re-tag it and push the image into ECR.

Once the image is in ECR, we can then create the apprunner services.

1. You'll need terraform installed
2. You'll need awscli installed
   1. Create a profile called alula with your aws account's keys
3. You'll need docker installed (to pull and push an image)

The following instructions are run in a terminal, inside the terraform folder.

This will install the necessary providers to apply the changes.

terraform init

This runs a sanity check on the terraform files, will output what would be changed when applied.

terraform plan

This will apply the changes and create the infrastructure, run the app.

terraform apply

Output will look similar to this (ran apply wrapped with time)

Apply complete! Resources: 24 added, 0 changed, 0 destroyed.

Outputs:

This will remove the infrastructure.
