- Dockerfile commands
RUN= during build time, run commands and save the resultENTRYPOINT= during run time- make the container act as an executable, commands given by CLI are treated as arguments to this executable
CMD= during run time- execute a default command if no command given by CLI
- if there is an
ENTRYPOINT, this will instead set default arguments, which can be overridden by CLI - think of
CMDas default arguments to thedocker runcommand
