How to create an "iddle" pod with an image that has an environment ready to run commands

Hi, is there any way to create a pod that runs a container with a specific Docker image but with no entrypoint at all. This image will have a ruby project with an environment set ready to run some useful scripts we use to execute manually.

We found a way and is to execute the following command as the entrypoint in the docker image:

ENTRYPOINT /bin/bash -c "sleep infinity"

But other issues appeared with this approach (for example we could not execute commands in our gitlab.ci.yaml with that image because the sleep seems to block those commands)

Thanks!
