await publishEndpoint.Publish(new OrderUpdated(existingOrder.Id, existingOrder.Address, existingOrder.Quantity, existingOrder.CreatedDate))

Similary, in the PutAsync method the message is published. await publishEndpoint.Publish(new OrderCreated(order.Id, order.Address, order.Quantity, order.CreatedDate)) In the PostAsync method, after the Order is created, the message is published to RabbitMQ. The constructor get the object IPublishEndpoint and it is used for publishing messages. Var item = await repository.GetAsync(id) Īwait publishEndpoint.Publish(new OrderDeleted(id)) Var existingOrder = await repository.GetAsync(id) ĮxistingOrder.Address = updateItemDto.Address ĮxistingOrder.Quantity = updateItemDto.Quantity Īwait repository.UpdateAsync(existingOrder) Īwait publishEndpoint.Publish(new OrderUpdated(existingOrder.Id, existingOrder.Address, existingOrder.Quantity, existingOrder.CreatedDate)) Public async Task PutAsync(Guid id, UpdateOrderDto updateItemDto) Public IConfiguration Configuration, order) Public Startup(IConfiguration configuration)

Now open appsettings.json file and add section for RabbitMQSettings as shown below: Then RabbitMQ will deliver those messages asynchronously to ProcessCenter microservice.įirst of all, add 2 NuGet packages to the CommandCenter ASP.NET Core application: This microservice will be set as Publisher so it will publish messages to RabbitMQ. Let us now integrate RabbitMQ to our first Microservice which is CommandCenter. Setting Publisher microservice in RabbitMQ I strongly advise you to prefer docker approach since microservices knowledge is incomplete without the usage of docker.

If you don’t want to use docker for rabbitmq then you can install it through packages manager like Chocolatey. We will come to this portal later on when we will integrate RabbitMQ in the microservices. This will take you inside the portal where you can see exchanges, queues for the messages.

Now in your browse open the url of the RabbitMQ management portal, this url is For the username and password enter “guest” and click the Login button.

This command will execute the yaml file code and soon RabbitMQ will start running from a docker container in your pc. Now, in the command prompt window, navigate to the folder of this file and run the following command: docker-compose up -d This will prevent data loss in case the container crashes. We made the use of docker volume for the rabbitmq container. The port 15672 will open rabbitmq management portal on the browser while the port 5672 will be used by the microservices to communicate with rabbitmq.ģ. Ports of the container 562 are exposed to the host. Two images rabbitmq and management are specified and these will run from a docker container named “rabbitmq”.Ģ. You will find this file in the source code folder. Messages can be anything like a simple string or a class object. After the messages are delivered RabbitMQ deletes them from it’s own storage. RabbitMQ stores these messages on it’s local storage and delivers them to another microservice which is called as Consumer. So this microservice is called as a Publisher. In simple words, a microservice publishes messages to RabbitMQ. RabbitMQ ensures that the messages are never lost and get delivered to the respective consumer. RabbitMQ is an open-source and most popular message broker service which you can use for performing asynchronous communication between microservices.

You can find this tutorial’s the complete Source Code at my GitHub Repository. We will change this communication to Asynchronous one by using RabbitMQ which is an open-source message broker.
