Jie Yu commented on MESOS-5081: ------------------------------- Yeah, we should fix that. > Posix disk isolator allows unrestricted sandbox disk usage if the > executor/task doesn't specify disk resource > ------------------------------------------------------------------------------------------------------------- > > Key: MESOS-5081 > URL: https://issues.apache.org/jira/browse/MESOS-5081 > Project: Mesos > Issue Type: Bug > Components: containerization > Reporter: Yan Xu > Labels: mesosphere > Fix For: 0.29.0 > > > This is the case even if {{flags.enforce_container_disk_quota}} is true. When > a task/executor doesn't specify a disk resource, it still gets to write to > the container sandbox. However the posix disk isolator doesn't limit it. > Even though tasks always have access to the sandbox, it should be able to > write zero bytes if it doesn't have any {{disk}} resource (it can still touch > files). This likely will cause tasks to immediately fail due to > stdout/stderr/executor download, etc. but should be the correct behavior > (when {{flags.enforce_container_disk_quota}} is true). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
