In which case should you use an ENTRYPOINT and CMD combination in a Dockerfile?

when you want your container to start without any command

when you want to open Bash by default

when you want to set the main command for starting the container $($ENTRYPOINT$)$ and the default argument $($CMD$)$

when you want to disable the overriding of the container default command

only when you need to package the application for Docker Hub
