Description

There are some things that could be improved:

• We could use Alpine Linux instead of Debian
• build-essential is not needed, the image only needs gcc
• We should remove cache after needed packages installation
• We could add a Docker ignore to ignore some files not needed in the context
• As multiple ADD commands are executed, this creates a multilayer that could be improved using a single COPY command.
