Operating system and Environment details

Issue

We have Amazon autoscale group, and want that every time, when launched new instance some jobs begin work. So we create job with system sheduler. But time to time nomad doesn't launch anything, when newly created amazon instance first launch. As our workaround we use node-drain, every time at instance launch(inti.d script),

nomad node-drain -enable -yes -self
sleep 3
nomad node-drain -disable -yes -self

after which nomad begin place system task well. This happens also on nomad 0.3.2

Little addon. Seems that nomad launching system jobs, but make it time to time very long. I mean that when instance starts, nomad may frustrate 7-10 minutes before launching anything

[tantra35]

Again little addon, we found that simple nomad node-drain -disable -yes -self enough
