What is entrypoint in Docker?

Question

Can anyone tell me what is entrypoint in Docker?

Answer 1

ENTRYPOINT instruction enables you to configure a container that will run as an executable. It seems similar to CMD since it also helps you to specify a command with parameters. But, the main difference between ENTRYPOINT and CMD is ENTRYPOINT command and parameters are not ignored if Docker container runs with command line parameters.

ENTRYPOINT has two forms:

ENTRYPOINT ["executable", "param1", "param2"] (exec form, preferred)

ENTRYPOINT command param1 param2 (shell form)
