When executing docker pull or docker run command, the daemon first checks for a similar image in the local machine by comparing the digests of the image.
If it finds a match, the daemon simply creates a copy of the already existing image. However, if a copy is not found, it starts pulling it from the registry. The same process is done when building a docker image using a Dockerfile.
Clean build
If you want to skip this behavior, you can perform a clean build using the following command:
docker build --no-cache -t <image> -f <dockerfile> .
To perform a clean build, all you need to do is to add the --no-cache option to the build command.
