Overview
Takes a Dockerfile and produces a Docker image. The default location for the Dockerfile is the current directory: the local directory must contain the Dockerfile and whatever else is required to go into the image.
docker build --rm=true -t <tag> <path>|<url> .
The image goes into the local repository and it is declared
