Using Service Connectors with MySQL

This tutorial takes you through setting up a .NET Core application with the MySQL service connector.

Note

For more detailed examples, please refer to the MySql project in the Steeltoe Samples Repository.

First, start a MySQL instance using the Steeltoe dockerfile.

docker run --env MYSQL_ROOT_PASSWORD=Steeltoe456 --publish 3306:3306 steeltoeoss/mysql

Next, create a .NET Core WebAPI that interacts with MySQL

  1. Create a new ASP.NET Core WebAPI app with the Steeltoe Initializr

  2. Name the project "MySqlConnector"

  3. Add the "MySQL" dependency

  4. Click Generate to download a zip containing the new project

  5. Extract the zipped project and open in your IDE of choice

  6. Set the instance address in appsettings.json

    {
  "mysql": {
    "client": {
      "server": "127.0.0.1",
      "port": "3306",
      "username": "root",
      "password": "Steeltoe456"
    }
  }
}
    Tip

    Looking for additional params to use when connecting? Have a look at the docs

Run the application

dotnet run <PATH_TO>\MySqlConnector.csproj

Navigate to the endpoint (you may need to change the port number) http://localhost:5000/api/values

Once the app loads in the browser you will see a list of the default schema info installed with MySQL. "["CHARACTER_SETS","COLLATIONS","COLLATION_CHARACTER_SET_APPLICABILITY", "COLUMNS","COLUMN_PRIVILEGES" ..." *In cloud foundry this information is cleared. The app will return an empty collection "[]".
