run container on occasion: best practices?

[50Cal]

Hi,

I want to run a docker container once in a while. I'm wondering what the best practices are.

 

Here is what I got:

A container runs a python script with an ENTRYPOINT directive so I can supply extra parameters.

A User Script (which I think is a cron job?) is planned to run the container periodically once with one set of parameters, and again with another set. something like :

docker run --rm pyscript args1
docker run --rm pyscript args2

However, I also have ENV variables in the Dockerfile I want to set. I would have to put them into the `run` comands.

I figured one solution would be to use `docker start` and create an UnRaid docker template with the variables all set there. But `start` doesn't allow for adding extra parameters.

 

My question is, what would be the cleanest way to do this?

Should I just suck it up and put the variables right in the script? If the variable is a password of sorts, is this as secure putting a password in an UnRaid docker template?

docker start runs the container with all of the variables etc that the docker run / create command used.
