Per the discussion here, you should be able to reset the entrypoint with

ENTRYPOINT []

When you want to override the entrypoint in the run command:

For example if you want to attach and run sh inside the container

docker run -it --entrypoint='' my-image sh

Put this line in your Dockerfile

ENTRYPOINT []

There are two ways to go about it :

If you want the override to happen at build time , then create a docker file for child image and specify the new Entrypoint there
```
FROM PARENT_IMAGE
ENTRYPOINT [new_entry_point]
```

2.Another way would be to do the override at the runtime , i.e, by using the --entrypoint flag:

    docker run --entrypoint=/bin/bash CHILD_IMAGE

Thank you attention, but question is remove it, not change it. – fsword Oct 19 '16 at 12:52
You can remove it using --entrypoint="" in the run command. Thanks, Rambler! – taranaki Apr 27 '17 at 04:38

If you use docker-compose, entrypoint directive will override the one in Dockerfile.

Add this in your docker-compose.yml:

entrypoint: /the/entrypoint/I_want.sh
command: first_argument_to_be_executed
