Hi everyone :)

In a few articles, I plan to write a small project together with Microservice Architecture for exchange some information about this , the things that are said are my opinion and you may have a different opinion that is respected by me and you can write in the comments section :)

You can see the project source in this Github Repository

Our example is a shop , we have six microservices that is Asp Core Web API On .Net 6

1. AuthMicroservice : Register User And Login Services
2. ProductsMicroService : Add Edit Update Products Category And Products
3. BasketMicroService : Our Shop Basket , Add Edit And Delete Basket Items And Use DiscountCode In Basket
4. DiscountMicroservice : Add Edit Delete Discount Code
5. OrderMicroService : Save Orders , See Order Details
6. PaymentMicroService : Pay Our Orders

and have one endpoint for our UI that is a ASP Core Mvc Project

at last a API Getway by Ocelot

We can see the implementing schema in the picture

Microservice Schema

Technologies used in the project

1. Ocelot For Api Getway
2. RabbitMQ For Message Broker
3. JWT Token For Authentication And Authorization
4. SQL Server And MongoDB For Databases
5. ASP Core Web Api For Our Rest Api And Swagger As Open API
6. Google RPC (GRPC) For Transfer Data Between Microservice
7. Docker For Run Database Services ( SQL Server , MongoDB ) And Message Broker ( RabbitMQ )

How Run Project

for run this project we need some service , there is SQL Server , RabbitMQ and MongoDB

if like me some service have installed before , you can just run the service is not installed , for example i have sqlserver and mongodb in my system , so just run rabbitmq by docker by this code

docker run --rm -it -p 15672:15672 -p 5672:5672 rabbitmq:3-management

then we can run project :) , notice that if use installed service the connection in appsettings.json file in projects must be config as the installed information

for example I use sql server by this connection string , and must change appsettings.json project file to config it.

Server=.; Initial Catalog=AuthDB;Integrated Security=True;MultipleActiveResultSets=True

you can see separate run code service by docker

For Run Separatly On Docker
Run RabbitMQ:
docker run --rm -it -p 15672:15672 -p 5672:5672 rabbitmq:3-management
Run Sql Server:
docker run -e "ACCEPT_EULA=Y" -e "MSSQL_SA_PASSWORD=str0ngp@ssword" -e "MSSQL_PID=Express" -p 1433:1433 -d mcr.microsoft.com/mssql/server:2019-latest
Run MongoDB:
docker run -d -p 27017:27017 --name example-mongo mongo:latest

but if you do not use installed service , like my laptop , just run the docker compose command to install and run services and do not need to change appsettings.json file because the configs is set for docker file.

just run docker-compose up command in the folder has the file docker-compose.yml ( in the root of project files)

all the service are up and just must run project :)

its better run all project together , for do this right click on solution file and click properties and select multiple startup project and start all service except ShareServices project that is a class library.

if we start the project all microservice will be run on different port and can see all projects :).

If you have any problems with the run of the project, you can ask me in the comments :)

In the next article, we will go to develop AuthMicroservice and continue our work.

Of course, we still have a lot of work to do, but you can see the full source of these articles here.

I hope you like this article :)
