How to create a docker image of an ASP.NET Core application for ubuntu?

Question

ASP.NET

I wrote an application in Visual studio, installed the docker tool for windows and added docker support to the project.
MS guides show options for publishing on Azure, how then to build an image for deployment on ubuntu?
2) Is it possible to set up image assembly and deployment directly to the server?

Answer 1

1. Official repository , branch from these images in your Dockerfile
   
2. Deploying to the server is done either through the Docker Registry, or through crutches with docker export/import.
