Add option to define/override entrypoint

[mickaelperrin]

Hi,

Currently, we can override the default command of a docker image by using the label "ofelia.job-run.TAG.command", it would be great if we could also define/redefine/delete the entrypoint by having a "ofelia.job-run.TAG.entrypoint" label.

Use case I encounter, is that I reuse the same image as the database image in a job-run. That image contains the backup script I want to trigger, but the entrypoint does some things that I don't need, and I would like to bypass.

When using the CLI the argument to pass to a docker run command is simply: --entrypoint="". So i guess that an empty label will do the thing for me and will allow also to redefine the entrypoint if needed by others.

Just to mention it: DBMS should be run alone in a container without any additions - not even scripts. Any maintenance, backup or whatever scripts should be delivered and run in it's own container image - and required access to the database should be done via internal network or shared volume(s).
