rancher-rebalancer's Issues

CATTLE_URL is not set

When launching the docker container on Rancher 1.6.15, it stops immediately with an error saying CATTLE_URL is not set

Feature request: A bit more flexibility with affinity rules

I have a bunch of nodes with label worker = 1 and a bunch with worker = 0 that contains specifically placed services and no workloads, unfortunately, any affinity rules make the rebalancer skip the balancing.
Any way around this would be awesome :)

Memory fault?

Ideas?
