Also, I'm able to run the dotnet-sdk dapr sample with tye with no issue.

I also tried to run it in wsl2 and wsl in docker (both set to run as linux, haven't tried to run docker in windows containers as I assumed it dapr wouldnt work).

Currently, we don't have the neat solution for waiting Db started (see https://github.com/vietnam-devs/coolstore-microservices/blob/master/deploys/dockers/mssqldb/init.sh) so that we need to re-visit it later.

The Idea is using k8s StatefulSets, then Db need to write out something to the output (file-system maybe), the service needs to check the waiting status using dockerize or wait-for-it

Installation via docker should be replaced with :
docker-compose -f docker-compose.base.yml -f docker-compose.base.override.yml -f docker-compose.yml -f docker-compose.override.yml up -d
And .env to catch user home instead of :
LOCAL_NUGET_PATH=/c/Users/Thang Chung/.nuget/packages

Hi,
@thangchung How can I run microservices and required docker infrastructure on gitpod in your project? where is its configuration for gitpod?

What did know about an demo implemention with RabbitMQ between some microsservices under CQRS and Event Source?

A brief hello from one of your beneficiaries of a great project.

Keep up the good work.

I am trying to compile code from master branch. I took latest version of netcorekit and getting compiling issues. please help.

Upgrade to latest version of netcorekit with gRPC protocol out of the box.

It's great if we can support Docker for Mac also!

• Using Istio networking.istio.io/v1alpha3 for API gateway, instead of Nginx as right now
• Refactor to remove aggregation service to avoid duplicated code

1. Build docker image
2. Publish it to vndg (docker hub) automatically

Hi

Thanks for the clear repository and architecture :) !

I try to run this project in Docker with the command "docker-compose up" but I directly get this error:
docker-compose : Service 'migration-data' depends on service 'sqlserver' which is undefined.

Can someone help me what i'm doing wrong ?
With other projects I don't have any problems with docker.

Thanks.

Hello,

First of all, thanks for this cool project. Been looking to find something like this as a guide on my software development projects (other than using ABP).

This may not actually be an issue but I was trying to have a successful build but the solution fails because KeyValueObject is missing. Can't find it anywhere in code. Please point me in the right direction.

public static class EnumHelper
{
public static IEnumerable<KeyValueObject> GetEnumKeyValue<TEnum, TKey>()
where TKey : class
{
var metas = GetMetadata<TEnum, TKey>();
var results = metas.Item1.Zip(metas.Item2, (key, value) =>
new KeyValueObject
(
key,
value
)
);
return results;
}

    public static (IEnumerable<TKey>, IEnumerable<string>) GetMetadata<TEnum, TKey>()
    {
        var keyArray = (TKey[])Enum.GetValues(typeof(TEnum));
        var nameArray = Enum.GetNames(typeof(TEnum));

        var keys = new List<TKey>();
        foreach (var item in keyArray) keys.Add(item);

        var names = new List<string>();
        foreach (var item in nameArray) names.Add(item);

        return (keys, names);
    }
}

Thank you very much.

I'm trying to make your PoC work.

However i fail to follow your guide from this site: https://hackernoon.com/5-steps-to-bring-coolstores-service-mesh-to-azure-kubernetes-service-aks-9cd1a5aa008a

For inventory container the error is:

The specified framework 'Microsoft.AspNetCore.App', version '2.1.6' was not found.

• Check application dependencies and target a framework version installed at:
  /usr/share/dotnet/
• Installing .NET Core prerequisites might help resolve this problem:
  http://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409
• The .NET Core framework and SDK can be installed from:
  https://aka.ms/dotnet-download
• The following versions are installed:
  2.1.5 at [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]

Additionally, i don't see anywere any ingress gateway configuration - i don't understand how you configure routing in this deployment.

Hi,

When a product is added to ShoppingCart service, how would that event update the Stock availability in Inventory service? Is it via event stream or via api update?

There are a few interesting use cases i'm facing:

• User add a near out of stock item to shopping cart, system update the inventory. However, the customer won't submit the order soon, how would you let other customer buy that same product?
• If Inventory service is degraded or down, would it affect checkout journey?

Thanks.

Thanks so much for the project and guidance. Any plans for a multitenant design?

I want to integrate YARP with DAPR. My use case is that when a user hits the yarp URL, the downstream of it must invoke the DAPR sidecar URL for service invocation Eg.

http(s)://<Yarp service >/api/< service name >/XXXXX (Upstream)
 To 
http://<Dapr-sidecar>/v1.0/invoke/< service name >/method/XXXXX (Downstream)

I'm not sure how I configure this as YARP routes.

Please help.

Currently, we host the GRPC inside out. Everything is seem fine, but this approach looks like has a lot of drawback such as 2 protocols (REST and gRPC) exposed, some of authentication and authorization functionalities are still processing... If we can have a way to work with GraphQL.NET on the server, and apollo-client for the front-end then it can be standardized with the normal use-case in many projects in the world. Just like below but for .NET ecosystem
