MySqlEFCore

MySQL Connector Sample App - Entity Framework Core

ASP.NET Core sample app illustrating how to use Entity Framework Core together with Steeltoe MySQL Connector for connecting to a MySQL service on CloudFoundry. There is also an additional sample that illustrates how to use a MySqlConnection to issue commands to the bound database.

General prerequisites

1. Installed .NET Core SDK

Running locally

1. Started MySQL docker container

Running on CloudFoundry

1. Installed CloudFoundry (optionally with Windows support)

Create MySQL Service Instance on CloudFoundry

You must first create an instance of the MySQL service in an org/space.

1. cf target -o your-org -s your-space
2. cf create-service p.mysql db-small myMySqlService

Publish App & Push to CloudFoundry

1. cf target -o your-org -s your-space
2. cd samples/Connectors/src/MySqlEFCore
3. Push the app
   • When using Windows containers:
     • Publish app to a local directory, specifying the runtime:
       • dotnet restore --configfile nuget.config
       • dotnet publish -r win-x64 --self-contained
     • Push the app using the appropriate manifest:
       • cf push -f manifest-windows.yml -p bin/Debug/net6.0/win-x64/publish
   • Otherwise:
     • Push the app using the appropriate manifest:
       • cf push -f manifest.yml

Note: The provided manifest will create an app named mysqlefcore-connector and attempt to bind the app to MySQL service myMySqlService.

What to expect - CloudFoundry

To see the logs as you startup and use the app: cf logs mysqlefcore-connector

On a Windows cell, you should see something like this during startup:

2016-07-01T07:27:49.73-0600 [CELL/0]     OUT Creating container
2016-07-01T07:27:51.11-0600 [CELL/0]     OUT Successfully created container
2016-07-01T07:27:57.73-0600 [APP/0]      OUT Hosting environment: development
2016-07-01T07:27:57.73-0600 [APP/0]      OUT Content root path:  /home/vcap/app
2016-07-01T07:27:57.73-0600 [APP/0]      OUT Now listening on: http://*:8080
2016-07-01T07:27:57.73-0600 [APP/0]      OUT Application started. Press Ctrl+C to shut down.

This sample will be available at http://mysqlefcore-connector.[your-cf-apps-domain]/.

Upon startup, the app inserts a couple of rows into the bound MySQL database. They are displayed on the home page.
