docker-compose up --force-recreate is one option, but if you’re using it for CI, I would start the build with docker-compose rm -f to stop and remove the containers and volumes (then follow it with pull and up).
This is what I use:
docker-compose rm -f
docker-compose pull
docker-compose up --build -d
# Run some tests
./tests
docker-compose stop -t 1
The reason containers are recreated is to preserve any data volumes that might be used (and it also happens to make up a lot faster).
If you’re doing CI you don’t want that, so just removing everything should get you want you want.
Update: use up --build which was added in docker-compose 1.7
