Please make micrservices using .netcore API orMVC with docker

I hope this image clarifies your query. let me know if anything specific you are looking for.

You can implement the whole stack locally with docker compose, then lift-and-shift the same containers to Azure Container Apps / AKS or AWS ECS / EKS. A successful microservices architecture relies on separation of concerns and independent deployment. Each service should have its own codebase, database, and be responsible for a single, well-defined function.

MicroservicesDemo – Developer-Friendly Guide

This guide is designed for developers to understand, run, and deploy a .NET Core microservices project with Angular frontend, JWT authentication, and Docker setup, ready for Azure deployment.

Backend Services (C# .NET Core)

• UserService : register/login endpoints, JWT token issuance

• ProductService : CRUD endpoints for products

• OrderService : CRUD endpoints for orders, calls ProductService via HTTP

• EF Core : each service has its own MS SQL database for persistence

Angular Frontend (v20)

• Login page stores JWT in localStorage

• Product page lists products and supports Add/Edit/Delete

• Communicates with backend APIs using JWT authentication

Dockerfile (production build) :

  
    FROM node:20 AS build
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build --prod
FROM nginx:alpine
COPY --from=build /app/dist/frontend /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
  

Docker Setup

docker-compose.yml :

  
    version: '3.8'
services:
  userservice:
    build: ./UserService
    ports: ["5001:80"]
    environment:
      - ConnectionStrings__DefaultConnection=Server=mssql;Database=UserDb;User Id=sa;Password=Your_password123;

  productservice:
    build: ./ProductService
    ports: ["5002:80"]
    depends_on: [userservice]

  orderservice:
    build: ./OrderService
    ports: ["5003:80"]
    depends_on: [userservice, productservice]

  frontend:
    build: ./Frontend
    ports: ["4200:80"]

  mssql:
    image: mcr.microsoft.com/mssql/server:2022-latest
    environment:
      SA_PASSWORD: "Your_password123"
      ACCEPT_EULA: "Y"
    ports: ["1433:1433"]
  

• Run locally: docker-compose up --build

Azure Deployment Steps

Step 1: Create Resources

  
    az login
az group create --name MicroservicesDemoRG --location eastus
az acr create --resource-group MicroservicesDemoRG --name microservicesacr --sku Basic
az sql server create --name usersqlserver --resource-group MicroservicesDemoRG --location eastus --admin-user azureuser --admin-password YourStrongPassword123
az sql db create --resource-group MicroservicesDemoRG --server usersqlserver --name UserDb --service-objective S0
# Repeat for ProductDb and OrderDb
  

Step 2: Push Docker Images to ACR

  
    az acr login --name microservicesacr
docker tag userservice microservicesacr.azurecr.io/userservice:latest
docker push microservicesacr.azurecr.io/userservice:latest
# Repeat for ProductService, OrderService, Frontend
  

Step 3: Deploy Services

  
    az appservice plan create --name MicroservicesPlan --resource-group MicroservicesDemoRG --sku B1 --is-linux
az webapp create --resource-group MicroservicesDemoRG --plan MicroservicesPlan --name userserviceapp --deployment-container-image-name microservicesacr.azurecr.io/userservice:latest
# Repeat for ProductService, OrderService, Frontend
  

Step 4: Configure Environment Variables

  
    az webapp config appsettings set --resource-group MicroservicesDemoRG --name userserviceapp --settings ConnectionStrings__DefaultConnection="Server=tcp:usersqlserver.database.windows.net,1433;Initial Catalog=UserDb;User ID=azureuser;Password=YourStrongPassword123;"
# Repeat for other services

        var token = new JwtSecurityToken(
            issuer: _config["Jwt:Issuer"],
            audience: _config["Jwt:Audience"],
            expires: DateTime.UtcNow.AddHours(1),
