Deploy .Net 6 app with multiple projects to Linux Elastic Beanstalk Server from mac development machine

I'm trying to Deploy .Net 6 app with multiple projects to Linux Elastic Beanstalk Server from mac development machine. I'm having trouble querying the api after it has been deployed. I've done it in 2 ways - Just an EC2 instance by following this tutorial, just using command line, and through Elastic beanstalk console. So I have 2 EC2 instances. They both say they are running.

The project has one Asp.Net app (Vepo.Web) and 5 helper projects for the app layers. the "Vepo" project is just a placeholder I made because the internet told me there is a bug when you name your dll different to your solution; and the solution is "Vepo.sln".

The files created by the publish look like this:

enter image description here

enter image description here

enter image description here

I got the source code to deploy by cd into my asp.net core web app (Vepo.Web), then run dotnet publish -r linux-x64 --self-contained false --output build, then go to "Vepo.Web/build" in finder. Then select all files > right-click > compress (do not compress the parent folder!). That creates "archive.zip". Then upload "archive.zip" in the Elastic Beanstalk Console. And now it looks like this:

enter image description here

But I don't seem to be able to query the api. In Postman I'm trying:

ec2-54-xxx-xxx-95.ap-southeast-2.compute.amazonaws.com:5001/Users

but I get:

Error: connect ECONNREFUSED 54.xxx.xxx.95:5000

And navigating to it gives me:

I have created these inbound rules to allow anyone in because I'm desperately trying to get in:

Can someone help me be able to hit endpoints in my web API without getting 404/401? I will give any information required if I'm missing something.

UPDATE: I guess the app is running when I ssh into it and run this command (no idea how to access it from postman or my app, going to this in the browser does not work https://ec2-54-xxx-xxx-53.ap-southeast-2.compute.amazonaws.com:5001/fashionitems/search?searchTerm=B&currentPage=1&pageSize=10):

P.S. I much prefer the console, I am a gui guy, and would way rather solve this with the AWS console.

Is this browser message any better? Sounds kinda like it exists but I need to provide auth/key:

I guess key things that seem wrong are "now listening on: http://localhost:5000" (shouldn't that be my ec2 instance public ipv4 address?) and "Hosting environment: Production" as I can only confirm development env working, so I will try to run locally in Production version now.

After adding as per accepted answer, it worked.:

public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
            webBuilder.UseUrls("http://*:5000");
        });
Solution

  • The answer basically try summarizing the different comments posted in the question.

    The problem can be motivated for many different reasons.

    The most important thing to keep in mind is that EB provides a nginx proxy for serving the application.

    By default this proxy expects your application to listen on port 5000.

    According to the logs you provided, the application seems to start properly and it successfully connect to the database.

    As you pointed out, it reports that the application is listening on http://localhost:5000: it may not be a problem, but perhaps your application is listening only in a certain network interface/address.

    Just to be sure, and in fact, at the end it seems to be the solution, configure your application Kestrel server to listen on the mask http://*:5000, using .UseUrls("http://*:5000") in your Startup class, for instance. This article provides several different options for configuring where the application should listen to.
