The machine-api-controller is currently stomping taints on nodes.

There is a PR to remedy this:

Sending to Cloud.

Comment 3 MinLi 2018-12-25 07:04:36 UTC
Feature of Scheduling relevant to Taints and Tolerations is all blocked by this bug.
Taints and tolerations allow the node to control which pods should (or should not) be scheduled on them.

attach trello list for reference:
