Extract files after running the formula with Docker

A formula can generate logs, when run locally, it is possible to get these files but when run with Docker, these files are only in the container.

I created a repository on GitHub to illustrate the problem, due to forum guidelines, I won’t paste the link, to get to this repository:

  • Username: afonsofilhozup
  • Repository: ritchie-formulas-docker-issues

To reproduce the problem:

  1. Add the repository in Ritchie
  2. Run the formula: rit docker-issues use volume --docker

This formula tries to read a text file that is passed as input and show it in the terminal, after that, create a log file. How to extract the log file using Docker?
