This is a basic Docker container for a C++ program
Build the image from Dockerfile with the command:
docker build -t cpp-container .
Once built, run the image:
docker run -it cpp-container
...or run it interactively in a shell:
docker run -it cpp-container sh
...or run it with a volume mounted to the current source code:
docker run -v "$(pwd)":/usr/src -it cpp-container
