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

For multiple containers writing to the same volume, you must individually design the applications running in those containers to handle writing to shared data stores to avoid data corruption. After that, exit the container and get back to the host environment.
Volumes are the best way to persist data in Docker. Bind mounts may be stored anywhere on the host system. They may even be important system files or directories. Non-Docker processes on the Docker host or a Docker container can modify them at any time.
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.
Worth a read Docker volumes

I'm mounting the same directory to several containers but for read purpose, not write (if your logs are written within the containers. I think that if they are writing to different files it Should work..
