Store optimizations

[pauldotyu]

Purpose

This change is mainly to reduce the size and startup time of the store-front and store-admin container images. The images were too large (>400MB) and could underperform in scale-out scenarios. Both store-front and store-admin were built with Vue.js and included a devserver which was used to proxy requests to other microservices.

To reduce the size of the containers, the Dockerfiles were updated to do a "production" build of the containers and run the JS files in a NGINX web server rather than running a server using the npm run serve command.

With NGINX now running as the proxy, an app architecture decision was made to move the ai-service behind the product-service and have the product-service serve as the proxy for ai-service. This was due to a limitation of the NGINX server's ability to conditionally proxy web requests to services that may or may not exist.

The store-front and store-admin container image sizes are now ~45MB (about 89% reduction)

Additional changes in this PR include Azure Developer CLI and Helm chart enhancements to allow for more configurable deployments (i.e., Azure CosmosDB API choice of MongoDB vs SQL API, and Azure Container Registry for application deployments).

How to Test

• Get the code

git clone https://github.com/Azure-Samples/aks-store-demo.git
cd aks-store-demo
git checkout store_optimizations

• Test the following scenarios
  Local dev with Docker Compose

docker compose up

Local dev with Docker Compose quickstart

docker compose -f  docker-compose-quickstart.yaml up -d

Azure with Azure Developer CLI (azd)

azd auth login
az login
azd up
// run `azd down` when done testing 

Azure with azd and Azure Container Registry (import containers from ghcr.io)

azd env set DEPLOY_AZURE_CONTAINER_REGISTRY true
azd up
// run `azd down` when done testing

Azure with azd and Azure Container Registry (build containers from source)

azd env set DEPLOY_AZURE_CONTAINER_REGISTRY true
azd env set BUILD_CONTAINERS true
azd up
// run `azd down` when done testing

Azure with azd and Azure CosmosDB SQL API

azd env set AZURE_COSMOSDB_ACCOUNT_KIND GlobalDocumentDB
azd up
// run `azd down` when done testing

What to Check

Verify that the following are valid

• Ensure store-front functionality is accessible from web
• Ensure store-admin functionality is accessible from web
• Ensure store-admin can get product descriptions from ai-service
