hi
How do I create a transaction in the handle?
Given that OrderDbContext is in the Infrastructure layer.
Transactions can be managed using Behaviours, but I do not have access to Infrastructure in the application layer

Hi pro,
Can you support deploy to host windows server 2016?
Step by step deploy!

Hello,

I have been starting to use the project recently, which is great, but I have noticed connection timeout in pulling elasticsearch:7.9.2 and kibana:7.9.2. I think it would be better to use official images from hub.docker.com.
The availability and stability of Docker Hub are much more than other repositories.

I'm going to link a pull request to the issue, which was tested perfectly.

docker-compose -f docker-compose.yml -f docker-compose.override.yml up –d

WARNING: The WEBAPP_STORAGE_HOME variable is not set. Defaulting to a blank string.
WARNING: The HOME variable is not set. Defaulting to a blank string.
Creating network "run-aspnetcore-microservices_default" with the default driver
ERROR: No such service: –d

This error message is all I kept getting when running the following command:
Command => docker-compose -f docker-compose.yml -f docker-compose.override.yml up -d
Error Message => “Error response from daemon: Get https://registry-1.docker.io/v2/: 3 net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)"

THE FIX
Docker Dashboard -> Settings -> Experimental -> Uncheck "Use New Experimental Framework".

See link: FIX from Referenced Article found on forums.docker.com

For some reason when I run the Ordering.API's GET command to retrieve the orders I getting the following error

.SqlException (0x80131904): Cannot open database "OrderDb" requested by the login. The login failed.

However, if I run the same code from Visual Studio targeting the same database, the database gets created with seed data with no problem. After that... once with the seed data created by the instance running with Visual Studio, if I switch back to the OrderingAPI running in Docker and run GET orders again then I do see the seed data.

workaround solution applied;

Need stable solution.

hi. i'm using macbook air 2020 with m1 processor for this project. and i'm facing one issue that tells me

Google.Protobuf.Tools cannot determine host OS and CPU

after searching for a while i found that Grpc.AspNetCore version in cloned project (2.35.0) isn't supporting arm processors.
so change the code to:
<PackageReference Include="Grpc.AspNetCore" Version="2.44.0" />
in Discount.Grpc and Basket.API.
Thanks

Change gRPC to backend microservices communications

I have two Microservices. First Service for Customers and Second service for Invoice Service.

In Invoice MicroService, I will save only CustomerId in Invoice services. Using this CustomerId, I would like to retrieve all the related data for Customer Microservice. But i don't know to communicate async.

Any please get me some ideas and examples

Update Action return Coupon object while Repo return bool

Invoking any link you provide in the write up causes the error:

This site can’t be reachedhost.docker.internal’s server IP address could not be found.
Try:

Checking the connection
Checking the proxy, firewall, and DNS configuration
Running Windows Network Diagnostics
ERR_NAME_NOT_RESOLVED

I suggest removing the "event-sourcing" tag from the project as it does not exemplify this. The persistence mechanism present in the project is the Relational paradigm.

Existing solution consumes rabbitmq messages via middleware of Ordering microservices. This is not a good solution for it so refactor this feature to implement HostedService interface.

Hello. I'm here to tell you the ocelot.json configuration is wrong by this Docker and docker-compose files.
Your host and Ports are using the Docker internal network but I didn't see your config write this network bridge.
we've 2 ways to solve this problem:

First:

1. change all Host and Ports that you've written in the Ocelot ReRoutes configuration to this config so don't need network-bridge anymore:
   Host: "host.docker.internal"
   Port: "the exposed port in docker-compose file"

I think this will work right.

the final Sample ocelot.json file after I have just changed Host and Ports

"DownstreamPathTemplate": "/api/v1/Discount/{productName}", "DownstreamScheme": "http", "DownstreamHostAndPorts": [ { "Host": "host.docker.internal", "Port": 5003 //this port have exposed in docker-compose.override.yml file }

Second:

1. create a network bridge in docker-compose and then use that network for all containers.
   In this way, ocelot will use Internal docker network that knows the Host and Ports.

Done.

the final Sample ocelot.json file after I have created the network-bridge

"DownstreamPathTemplate": "/api/v1/Discount/{productName}", "DownstreamScheme": "http", "DownstreamHostAndPorts": [ { "Host": "discount_api", // My container_name "Port": 80 //this port have exposed in DockerFile }

if you have any questions let's be easy and ask.

In Ordering microservice EntityBase should be generic and following refactoring should be applied in order to provide SOLID properly.

this project need upgrade to .NET 6
with new future like (distribute, and local transaction , identity server ,...)

I am trying last 3 days sql server database connectivity not work

compose file below

orderdb:
container_name: orderdb

How to fix this issues

I have try to remove orderdb and try this host.docker.internal,1433 working fine so how to multicontainer setup

Based on your coding, the service related to receiving the email settings in section (InfrastructureServiceRegistartion) will not be returned, please help.

Hi,

I followed the course with all the steps from version 3.1 until the video 22. Developing Presentation Layer - Create CatalogController Class for Catalog.API.
When I opened the course today, I realized that you updated the videos to .Net 5. I followed them in order to make it compatible (added Swashbuckle support, made some minor changes in Startup.cs and tried to run as you indicated).
When I run the microservice, it opens and the methods work except GetProductByCategory. It returns the following Exception:

An unhandled exception has occurred while executing the request.
      System.InvalidOperationException: The serializer for field 'Category' must implement IBsonArraySerializer and provide item serialization info.

I know it's not a course about RESTful principles but maybe you'll consider in the future extracting resource id from request body to path parameter ?

Do you have course for deploy this repo using azure services??

Any ideas?

Hi @mehmetozkaya,

I have tried to deploy run-aspnetcore-microservices on ARM64 using docker-compose. In docker-compose.yml file, there is one service named OrderDB which is using mcr.microsoft.com/mssql/server:2017-latest docker image. This image is not present for ARM64. I have commented regarding the release of the image. In that comment, an user suggested to use azure-sql-edge docker image instead of mcr.microsoft.com/mssql/server:2017-latest. After replacing it with azure-sql-edge all the health-checks are working fine.

Can you please share your opinion on the above change?

If you get this error running the command
docker-compose -f docker-compose.yml -f docker-compose.override.yml up -d
disable "Use Docker Compose V2" in docker settings

Just pulled all the file and run the docker compose. But can't connect with any API...
It says 404, any idea?

in basket api basketcontroller Checkout:

var basket = await _repository.GetBasket(basketCheckout.UserName);
if (basket == null)
{
return BadRequest();
}

        // send checkout event to rabbitmq
        var eventMessage = _mapper.Map<BasketCheckoutEvent>(basketCheckout);
        eventMessage.TotalPrice = basket.TotalPrice;
        await _publishEndpoint.Publish<BasketCheckoutEvent>(eventMessage);

        // remove the basket
        await _repository.DeleteBasket(basket.UserName);

        return Accepted();

if MassTransit publish or IBasketRepository delete fail，the checkout business is fail . can you use the transcation to achieve
checkout 's atomicity ,fianlly this is comply eventual consistency,
thank you!

According to the course lectures, the reasoning behind registering the email service as transient is to prevent the service from being created for every request and to use a single instance throughout the application lifetime. This means that the service must be registered as singleton since transient means a new instance will be created EVERY TIME the service is requested from the dependency injection framework.
