How to run already developed ASP.NET Core app on Ubuntu?

Question

What is the easiest way to run my existing ASP.NET Core application on Ubuntu? I have found this: https://learn.microsoft.com/en-us/aspnet/core/publishing/linuxproduction but I am stuck on this:

I have published the application and copied it to my Ubuntu, but I have no idea how can I "run the app". Any help will be really appreciated.

Scroll down in that doc file, it tell you how to start it later on... — DavidG

It's really as simple as executing:

dotnet path/to/your/application.dll

However, for a website you really want to manage that with some sort of init system. The doc file you link to tells you how to start your application using Systemd.

Create a service definition file e.g. /etc/systemd/system/myapp.service

Edit the file to look like this, replacing the relevant parts where necessary:

[Unit]
Description=Example .NET Web API Application running on Ubuntu

[Service]
WorkingDirectory=/var/path/to/your/app
ExecStart=/usr/bin/dotnet /var/path/to/your/app/hellomvc.dll
Restart=always
RestartSec=10  # Restart service after 10 seconds if dotnet service crashes
SyslogIdentifier=dotnet-example
User=www-data
Environment=ASPNETCORE_ENVIRONMENT=Production 

[Install]
WantedBy=multi-user.target

Enable the service like this:
```
systemctl enable myapp.service
```
Start the service:
```
systemctl start myapp.service
```
Check if your service is running:
```
systemctl status myapp.service
```

If you have another init system, the instructions will of course be quite different.

Note: This only starts the app running on your machine. If you intend to serve it to the public, then it is highly recommended that you use a proxy such as Nginx as Microsoft has not yet certified Kestrel as an edge server.

@meziantou You should really point out that it's your blog when posting things like that. Especially when you've already posted it an hour ago on the question.
