CoolStore Web Application - :ferris_wheel: Modern Application on Dapr and Tye :sailboat:

Travis (.org) Gitpod ready-to-code Price

CoolStore Website is a containerised microservices application consisting of services based on .NET Core running on Dapr. It demonstrates how to wire up small microservices into a larger application using microservice architectural principals.

This repository based on some of the old libraries. So be careful if you use it in your production environment!!!

We are working on practical-clean-ddd for the new version of building the .NET apps with domain-driven design, clean architecture with Docker, Kubernetes, Tye, and Dapr in a practical way 👍

Read documentation for more information.

The business domain is inspired from CoolStore project by JBoss Demo Central and Red Hat Demo Central.

Dapr Building Blocks

Name Usecase Apps Participants
Service-to-service invocation - User clicks to the detail product
- Populate product information for shopping cart items
- Order gets detail information of buyer
productcatalogapp, inventoryapp, shoppingcartapp, identityapp
State management Items in the shopping cart shoppingcartapp
Publish and subscribe User clicks checkout button, and the checkout process happens. It triggers the pub/sub flow in the system shoppingcartapp, saleapp, identityapp
Resource bindings Every 30 seconds and 1 minutes the validation process happens. It will change the status of order from Received to Process and Complete via Cron binding productcatalogapp, inventoryapp
Observability All apps in the application are injected by daprd so that it's tracked and observed by dapr identityapp, webapigatewayapp, inventoryapp, productcatalogapp, shoppingcartapp, saleapp, web
Secrets Bind with local secret file to hide password of redis inventoryapp, productcatalogapp, shoppingcartapp, saleapp

Try it

Make sure you have

dapr
and
tye
installed on your machine!

Only wanna see wth is it?

$ tye run

Go to

http://localhost:8000
, and you're able to access to several endpoints whenevever it's ready as below:

Wanna go deeply to see how can we built it!

  1. Start core components
$ tye run tye.slim.yaml
  1. Start dapr apps locally via dapr cli
$ dapr run --app-port 5001 --app-id identityapp dotnet run -- -p src\Services\Identity\IdentityService\IdentityService.csproj
$ dapr run --app-port 5002 --app-id inventoryapp dotnet run -- -p src\Services\Inventory\InventoryService.Api\InventoryService.Api.csproj
$ dapr run --app-port 5003 --app-id productcatalogapp dotnet run -- -p src\Services\ProductCatalog\ProductCatalogService.Api\ProductCatalogService.Api.csproj
$ dapr run --app-port 5004 --app-id shoppingcartapp dotnet run -- -p src\Services\ShoppingCart\ShoppingCartService.Api\ShoppingCartService.Api.csproj

Now, you can start to develop, debug or explore more about

dapr
with
tye
via Coolstore Apps.

Enable

vm.max_map_count
for ElasticSearch via run
sysctl -w vm.max_map_count=262144
