Joseph Wu reassigned MESOS-7947:
--------------------------------
Assignee: Joseph Wu (was: Qian Zhang)
I see three distinct, and possibly complimentary approaches to getting GC into
nested containers:
# We can add a new Agent API, like {{GC_NESTED_CONTAINER}}, which can be called
after the launch of a nested container. This call would either mark the nested
sandbox for GC like any other sandbox, or would manually schedule the GC for
some time in the future.
# We can extend the {{LAUNCH_NESTED_CONTAINER}} call with a field that tells
the agent to schedule GC of the nested sandbox upon the nested container's
exit. We might give this field a default value to retain the current leaky
behavior, or opt to GC by default.
# We can silently schedule nested sandboxes for GC. We might even do so based
on the agent's {{gc_disk_headroom}} and {{gc_delay}} and the task's {{disk}}
resource (which means instant GC for tasks that request 0 disk).
[~qianzhang] I'm wondering if you have any thoughts about this (being the
previous assignee).
