## Compose sample application: ASP.NET with MS SQL server database Project structure: ``` . ├── app │   ├── aspnetapp │   │   ├── appsettings.Development.json | | └── ... │   ├── ... │   └── Dockerfile └── compose.yaml ``` [_compose.yaml_](compose.yaml) ``` services: web: build: app ports: - 80:80 db: # mssql server image isn't available for arm64 architecture, so we use azure-sql instead image: mcr.microsoft.com/azure-sql-edge:1.0.4 # If you really want to use MS SQL Server, uncomment the following line #image: mcr.microsoft.com/mssql/server ... ``` The compose file defines an application with two services `web` and `db`. The image for the web service is built with the Dockerfile inside the `app` directory (build parameter). When deploying the application, docker compose maps the container port 80 to port 80 of the host as specified in the file. Make sure port 80 on the host is not being used by another container, otherwise the port should be changed. > ℹ️ **_INFO_** > For compatibility purpose between `AMD64` and `ARM64` architecture, we use Azure SQL Edge as database instead of MS SQL Server. > You still can use the MS SQL Server image by uncommenting the following line in the Compose file > `#image: mcr.microsoft.com/mssql/server` ## Deploy with docker compose ``` $ docker compose up -d Creating network "aspnet-mssql_default" with the default driver Building web Step 1/13 : FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build 2.1: Pulling from dotnet/core/sdk .... .... a9dca2f6722a: Pull complete Digest: sha256:9b700672670bb3db4b212e8aef841ca79eb2fce7d5975a5ce35b7129a9b90ec0 Status: Downloaded newer image for microsoft/mssql-server-linux:latest Creating aspnet-mssql_web_1 ... done Creating aspnet-mssql_db_1 ... done ``` ## Expected result Listing containers must show two containers running and the port mapping as below: ``` $ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 7f3a2a7ea5c0 microsoft/mssql-server-linux "/opt/mssql/bin/sqls…" 4 minutes ago Up 4 minutes 1433/tcp aspnet-mssql_db_1 27342dde8b64 aspnet-mssql_web "dotnet aspnetapp.dll" 4 minutes ago Up 4 minutes 0.0.0.0:80->80/tcp aspnet-mssql_web_1 ``` After the application starts, navigate to `http://localhost:80` in your web browser. ![page](output.jpg) Stop and remove the containers ``` $ docker compose down ```
