Hi All, I need to have a very simple docker, where I can execute various curl commands at a specific times. Basically bare Linux with some common tools and cron. Any suggestions?

Why do you need a docker? Have you tried using the user scripts plugin?

I want a docker to put it in the same network, among other dockers using the same gateway. Thought this is he way   

Each docker is its own separate container, you can execute commands within the container with docker -exec or you can map outside directories so the containers can see them. 

What exactly do you wish to accomplish?
