Yan Xu reassigned MESOS-3190: ----------------------------- Assignee: Yan Xu > Implement bind mount based provisioner backend for AppC. > -------------------------------------------------------- > > Key: MESOS-3190 > URL: https://issues.apache.org/jira/browse/MESOS-3190 > Project: Mesos > Issue Type: Task > Reporter: Jie Yu > Assignee: Yan Xu > > This is a specialized backend that may be useful for deployments using large > (multi-GB) single-layer images and where more recent kernel features such as > overlayfs are not available. > For small images (10's to 100's of MB) the Copy backend may be sufficient. > 1) It supports only a single layer. Multi-layer images will fail to provision > and the container will fail to launch! > 2) The filesystem is read-only because all containers using this image share > the source. Select writable areas can be achieved by mounting read-write > volumes to places like /tmp, /var/tmp, /home, etc. using the ContainerInfo. > These can be relative to the executor work directory. > 3) It relies on the image persisting in the store. > 4) It's fast because the bind mount requires (nearly) zero IO. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
