Running a self-contained ASP.NET Core application on Ubuntu

Answer

Now, how do I run my application? My understanding is that because it is a self-contained .NET Core application I do not need to download and install .NET Core anything. My application should contain everything it needs.

You are correct. Run the executable.

When you create a self-contained app, the publish output "contains the complete set of files (both your app files and all .NET Core files) needed to launch your app." That includes the executable.

Example Self-Contained Deployment

Here is the output of dotnet publish -c release -r ubuntu.14.04-x64 for a simple self-contained application. Copy the publish directory to Ubuntu and run the executable.

C:\MyApp\bin\release\netcoreapp1.0\ubuntu.14.04-x64\publish\

This document differentiates between framework-dependent and self-contained deployments.

Follow the below steps to run your application:

1. Publish your application as a self contained application:

   dotnet publish -c release -r ubuntu.16.04-x64 --self-contained
   

2. Copy the publish folder to the Ubuntu machine

3. Open the Ubuntu machine terminal (CLI) and go to the project directory

4. Provide execute permissions:

   chmod 777 ./appname
   

5. Execute the application

   ./appname
