dockerfile - Can I mount same volume to multiple docker containers

Question

I need to share the application logs to mounted volume. I want to mount same volume to all docker containers to keep the logs. is it possible? will it effect the application running on each container?

docker run -d  --name C1 -v /home/ubuntu/logs:/usr/local/apache/htdocs/ httpd
docker run -d  --name C2 -v /home/ubuntu/logs:/etc/app/logs my-docker-image:latest
docker run -d  --name C3 -v /home/ubuntu/logs:/usr/logs TestImage:latest

Yes you can add same location as a volume to many docker containers.

Additionally you can use --volumes-from to mount your log directory in one container not actually running any application and then use the volumes from this container in your other containers without having to repeat the paths everywhere.
