This is a sample microservice solution for Azure Container Apps. It will create a series of microservices for managing orders and inventory. Dapr is used to secure communication and calls between services and Azure Cosmos DB is created alongside the microservices.

Note: This solution is a fork from the original. It's been changed a lot, but thanks to the original team who put this together!

Deployment is done via Bicep with a simple bash script to get you started. You can fork the repo and run the below script in bash or GitHub Codespaces.

Just run the ./start.sh script to deploy everything. You can edit the LOCATION variable in the script if needed.

Some notes on how to test the app here

Container images are hosted in GitHub Container Registry.

The "official" images are here: https://github.com/orgs/Azure/packages?tab=packages&q=container-apps-demo

ghcr.io/azure/container-apps-demo/store-service
ghcr.io/azure/container-apps-demo/order-service
ghcr.io/azure/container-apps-demo/inventory-service

The below steps are for working locally, but this is optional.

export GITHUB_CR_PAT='' # set in bash profile
docker login ghcr.io -u chzbrgr71 -p $GITHUB_CR_PAT

export TAG='v1.21'

docker build -t chzbrgr71/store-service:$TAG ./store-service
docker build -t chzbrgr71/inventory-service:$TAG ./inventory-service
docker build -t chzbrgr71/order-service:$TAG ./order-service

docker tag chzbrgr71/store-service:$TAG ghcr.io/chzbrgr71/store-service:$TAG
docker tag chzbrgr71/inventory-service:$TAG ghcr.io/chzbrgr71/inventory-service:$TAG
docker tag chzbrgr71/order-service:$TAG ghcr.io/chzbrgr71/order-service:$TAG

There are three main microservices in the solution.

The store-service is an express.js API that exposes three endpoints. / will return the primary index page, /order will return details on an order (retrieved from the order service), and /inventory will return details on an inventory item (retrieved from the inventory service).

The order-service is a Python flask app that will retrieve and store the state of orders. It uses Dapr state management to store the state of the orders. When deployed in Container Apps, Dapr is configured to point to an Azure Cosmos DB to back the state.

The inventory-service is a Go mux app that will retrieve and store the state of inventory.
