I have a docker composition with 3 contaiers. I would like to keep these 3 containers and recreate another instance of the composition, without reusing, nor deleteing the previous 3 containers. Conceptually, would be like running 2 intances of the same application, where the application is the composition.
Docker compose always tries to reuse the existing containers.

You can specify a different project for your compose file.
docker-compose -p namespace2 up -d
By default, the project name is the name of the directory where your docker-compose is. You could also create a new dir and copy your compose file into it. It's the same as specifying -p. It basically specifies the namespace for the objects in your compose file.

You can also pass a project name using the `$COMPOSE_PROJECT_NAME` environment variable – dnephin Sep 06 '16 at 14:14
