Hosting .Net Core app and Angular app under IIS Default website

Question

I'm using ASP.net core Boilerplate with angular. I tried hosting both apps individually website for Angular and website for .NET core under IIS localhost with no problem.
:
But When I want to deploy my App on public I encountered this problem :
1- I have only one public IP which is redirecting to the IIS Default Website and each app has a different port.
**So, Both Front-end and Back-end should be hosted under the IIS Default Website with a different port.

is that applicable with .NET core and Angular?**

Update

And here is my appsetting.json

{

  "ConnectionStrings": {
    "Default": "Server=localhost\\SQLEXPRESS; Database=MyDb;User Id=admin;Password=1234"
  },
  "App": {
    "ServerRootAddress": "http://localhost:21021/",
    "ClientRootAddress": "http://localhost:4200/",
    "CorsOrigins": "http://localhost:4200,http://localhost:8080,http://localhost:8081,http://localhost:3000"
  },
  "Authentication": {
    "JwtBearer": {
      "IsEnabled": "true",
      "SecurityKey": "MyApp_C421AAEE0D114E9C",
      "Issuer": "MyApp",
      "Audience": "MyApp"
    }
  }
}

Answer 1

Here are some steps:

Pre-requisite

Client Alias=> path name for client application which needed to add application in iis

Service Alias => path name for service application which needed to add application in iis

1. Download .NET Core 3.0 Runtime & Hosting Bundle for Windows or you can find exact version as per your project https://dotnet.microsoft.com/download/dotnet-core/thank-you/runtime-aspnetcore-3.0.0-windows-hosting-bundle-installer
2. For the setup of Angular 8 infrastructure in Clinical Content Editor, installation of IIS extension "URL Rewrite” is required https://www.iis.net/downloads/microsoft/url-rewrite

Front End:

3. Build your angular run ng build --prod --base-href=/client-alias/

4. Go to Default Web Site in IIS

5. Add a application

6. Add Alias and point physical path to your dist folder in angular application

7. You can test this http://localhost/client-alias

   Back End (https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/?view=aspnetcore-3.1#create-the-iis-site)

8. Publish the API project and so that we can copy the content to the new web application of API Service.

9. Create an application pool with .net CLR version to No Managed Code

10. In IIS create a new web application for API Service with application pool added in step 9 and physical path of published folder as in step 8.

Now these two application are running on as http://127.0.0.1/client-alias and http://127.0.0.1/service-alias

You can make your IP(8080) public with no another port open.

Answer 2

Only your angular Website should be public. Every IIS Website need an unique port. https://docs.aspnetzero.com/en/aspnet-core-angular/latest/Deployment-Angular-Publish-IIS

Also check out in your IIS Host Website the appSettings.json for

"App": {
    "ServerRootAddress": "http://localhost:21021/", -> Host 
    "ClientRootAddress": "http://localhost:4200/", -> Angular
    "CorsOrigins": "http://localhost:4200" -> your domain, https://docs.microsoft.com/en-us/aspnet/core/security/cors?view=aspnetcore-3.1

},
