Using Service Connectors with RabbitMQ

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

Note

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

First, start a RabbitMQ instance using the Steeltoe dockerfile.

docker run --publish 5672:5672 steeltoeoss/rabbitmq

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

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

2. Name the project "RabbitMQConnector"

3. Add the "RabbitMQ" 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. Validate the correct logging level is set in appsettings.json

   {
     "Logging": {
       "LogLevel": {
         "Default": "Debug",
         "System": "Information",
         "Microsoft": "Information",
         "Steeltoe": "Debug",
         "RabbitMQ_Connector": "Debug"
       }
     }
   }
   

   Note

   Make sure the correct logging is set or you'll miss the output. The default logging level should be set to Information.

7. Set the instance address in appsettings.json

   {
     "rabbitmq": {
       "client": {
         "server": "127.0.0.1",
         "port": "5672",
         "username": "guest",
         "password": "guest"
       }
     }
   }
   

   Tip

   If you would like to see how to customize the connection have a look at the docs

Run the application

• .NET cli
• Visual Studio

dotnet run <PATH_TO>\RabbitMQConnector.csproj

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

As the app loads in the browser it will create a message queue, listen for new messages on the queue, and write 5 messages. Once finished the output will let you know everything has completed - "Wrote 5 message to the info log. Have a look!". Looking at the app logs (console) you will see...

Received message: Message 1
Received message: Message 2
Received message: Message 3
