Can I run a command inside a Docker container from another container?

Question

Here is my script.

I have 2 docker containers:

• C1: a container with Ruby (but maybe something else) that prepares data files on which it must perform calculations in the Julia language.
• C2: a container with Julia (or R or Octave ...) used to perform the calculation to avoid installing Julia on the same system or container that runs Ruby code

From the host, obviously, I have no problems with processing. Usually, when two containers are connected (or belong to the same network), they exchange data with each other through a network that opens some kind of door. In this case, Julia does not open the door.

Can I run a command on C2 from C1, similar to what was done between the host and C2? If so, how?

Thank!
