Is it possible to reuse containers to run other site?

[VladSavitsky]

Thanks for this great tool. It was hard for me to start using docker but now seems all is right.

I want to have separate instance of site to run tests. Let's name dev-site which is under active development and test-site is for testing only. Test-site must have different database and codebase. Before I started 2 different sets of containers and configured network (I could provide docker-compose-files in it's necessary).

Now I have only one set of containers and use only dev-sites. I would like to add ability to run tests in parallel to dev-site. What is the best practice to do that? Can I run one set of containers for different sites (dev- and test-)?

Thanks.
