Hi people
This is my first visual studio 2019 console application with docker support (OS: Windows Server 2019). I only want to run a docker container with “hello word”. So I have created a console app with .net core and docker support. The docker file is made automatically by visual studio.
The .net solution project is in: C:\dev\test02\
Then, I go to powershell and execute the docker build command in the same machine:
PS C:\dev\test02\test02> docker build -t dkapp2 .
And it says:
Sending build context to Docker daemon 178.7kB

The docker file build automatically buils Visual Studio is:
