Deploy .Net Core 2.1 Web API to Elastic Beanstalk

Question

I'm trying to get my .Net Core Web API Solution deployed to Elastic Beanstalk via CLI and I'm running into an issue. I am able to publish my project without errors and deploy the application successfully. My problem is that when I access the URL, I'm still seeing the Sample App.

Is there a config change that I can make to my app, or the web.config, or in Elastic Beanstalk that I should change to get my Web API deployed?

publish command

dotnet publish My.WebAPI/My.WebAPI.csproj --runtime win10-x64 --output my-api

web.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath=".\MyWebAPI.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
    </system.webServer>
  </location>
</configuration>

aws-windows-deployment-manifest.json

{
    "manifestVersion": 1,
    "deployments": {
        "aspNetCoreWeb": [
        {
            "name": "my-webapi",
            "parameters": {
                "appBundle": ".",
                "iisPath": "/",
                "iisWebSite": "Default Web Site"
            }
        }
        ]
    }
}

The solution was to fix the way I was zipping the publish content. My Jenkins deployment script is generating a custom zip. I was zipping the compiled code into a subdirectory, so my deployments were failing. I updated our zip command to flatten the archive, so all deployment files are in a flat file.

Per AWS Documentation: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/applications-sourcebundle.html (Relevant passage below)

When you use the AWS Elastic Beanstalk console to deploy a new application or an application version, you'll need to upload a source bundle. Your source bundle must meet the following requirements:

Consist of a single ZIP file or WAR file (you can include multiple WAR files inside your ZIP file)

Not exceed 512 MB

Not include a parent folder or top-level directory (subdirectories are fine)
