MongoDB Connector Sample App

ASP.NET Core sample app illustrating how to use Steeltoe MongoDB Connector for connecting to a MongoDB service on CloudFoundry.

General prerequisites

1. Installed .NET Core SDK

Running locally

1. Started MongoDB docker container

Running on CloudFoundry

1. Installed CloudFoundry (optionally with Windows support)
2. Installed VMware Tanzu Cloud Service Broker

Create MongoDB Service Instance on CloudFoundry

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

1. cf target -o your-org -s your-space
2. cf create-service csb-azure-mongodb small myMongoDbService

Publish App & Push to CloudFoundry

1. cf target -o your-org -s your-space
2. cd samples/Connectors/src/MongoDb
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 mongodb-connector and attempt to bind the app to MongoDB service myMongoDbService.

What to expect - CloudFoundry

To see the logs as you startup and use the app: cf logs mysql-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 Application started. Press Ctrl+C to shut down.

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

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