Public bug reported:
William and Robert developed the lxc-start-ephemeral script to support a
use case that the version in the package no longer supports, to the best
of our knowledge.
Specifically, we need to be able to programmatically start ephemeral
instances, send them a command and get the results, and then shut down
the instance. The packaged version instead starts an instance, directs
users to use lxc-console, and then starts lxc-monitor to wait for the
instance to close.
We may have missed a way to use the existing approach for what we need,
and are happy to talk about it.
If not, we believe that a nice solution would be to allow an option to
lxc-start-ephemeral for a command that, if provided, is run instead of
lxc-monitor. This command would be able to have a placeholder string;
before the command is run, the placeholder would be replaced by the name
of the ephemeral container. The command would inherit lxc-start-
ephemeral's stdout and stderr. After the command finished, lxc-start-
ephemeral would proceed to shut off the instance, just as it does now
after lxc-monitor.
Thank you
