Question

Whats the difference between CMD and ENTRYPOINT?

Answer 1

CMD sets default command and/or parameters, which can be overwritten from command line when docker container runs.

ENTRYPOINT configures a container that will run as an executable.

Answer 2

Both the instructions , we are using in DockerFile which defines what command get executed while running the container .

CMD from Dockerfile can be overwritten from command line when docker container runs and that CMD from Dockerfile will not be executed while running container .

ENTRYPOINT from Dockerfile will not be ignored when docker container runs with command line parameters.
