Pi Climb is deployed on AWS Elastic Container Service, in a single cluster, service and task. It can be scaled by increasing the number of tasks should utilisation increase.
Route 53 resolves name to ALB IP address. ALB routes traffic to appropriate container based on path rules /api/* to BE else FE. Traffic from 80/http is redirected to 443/https.
ECS service is on private-subnet with security group that only allows inbound traffic from ALB, which protects it from external excess. As Go BE requires Supabase connection, outbound traffic from the private-subnet is routed to the NAT gateway in the public-subnet, which has internet gateway access and allows access to external resources, while protecting internal services.
On push to release branch, the build-and-publish job is triggered. Web and server are built with dockerfile and pushed to Elastic Container Registry.
Deployment in next job uses ECS task definition to deploy containers with correct configurations.
