-----------------------------------
Summary: Support auto backend in Unified Containerizer.
Key: MESOS-5931
URL: https://issues.apache.org/jira/browse/MESOS-5931
Project: Mesos
Issue Type: Improvement
Components: containerization
Reporter: Gilbert Song
Currently in Unified Containerizer, copy backend will be selected by default.
This is not ideal, especially for production environment. It would take a long
time to prepare an huge container image to copy it from the store to
provisioner.
Ideally, we should support `auto backend`, which would
automatically/intelligently select the best/optimal backend for image
provisioner if user does not specify one from the agent flag.
We should have a logic design first in this ticket, to determine how we want to
choose the right backend (e.g., overlayfs or aufs should be preferred if
available from the kernel).
