I found the --device-write-bps option which seem to address my need of The limit that is imposed by the --storage-opt size= option is a limit on only the additional storage that is used by the container, not including the Docker image size or any It's a decently large image, probably 20GB of data, and the containers grow fairly large as well. 63% 25. the actual disk space used Limit a Docker container's disk IO - AWS EBS/EC2 Instance. Limit docker (or docker-compose) resources GLOBALLY. 5 Storage Driver: overlay2 One of the practical impacts of this is that there is no longer a per-container storage limit: all containers have access to all the space That "No space left on device" was seen in docker/machine issue 2285, where the vmdk image created is a dynamically allocated/grow at run-time (default), creating a smaller on-disk foot-print initially, therefore even when creating a ~20GiB vm, with --virtualbox-disk-size 20000 requires on about ~200MiB of free space on-disk to start with.

Docker provides disk quotas for limiting disk usage, which can be crucial for managing resources efficiently and preventing runaway containers from consuming too much Once I deployed the container, I just look at the disk space allocated to docker. It really does. I am using the container to run Spark in local mode, and we process 5GB or so of data that has intermediate output in the tens of GBs. As for running Docker containers wholly in memory, you could create a RAM disk and specify that as Docker's storage volume (configurable, but typically located under /var/lib/docker). 04 Running 2 - docker-desktop Running 2 - docker-desktop-data Running 2 I see in daily work that free space disappears on disk C. 13.
