krib-operate-drain

Configure consul agents.

This stage runs an Drain operation on a given KRIB built Kubernetes node. It uses the krib-operate-drain Profile

In addition - you may set the following Params on a Machine object to override the default behaviors of this stage:

• krib/operate-action - action to take (cordon or uncordon)
• krib/operate-on-node - a Kubernetes node name to operate on
• krib/operate-options - command line arguments to pass to the kubectl command for the action

If the krib/operate-on-node Param is empty, the node that is currently running the Stage will be operated on. Otherwise, specifying an alternate Node allows remote draining a node.

Warning

This Stage does a few things that MAY BE VERY BAD !!

1. service pods are ignored for the drain operation
2. --delete-local-data is used to evict pods using local storage

Default options are --ignore-daemonsets --delete-local-data to the drain operation. If you override these values (by setting 'krib/operate-options') you MAY NEED to re-specify these values, otherwise, the Node will NOT be drained properly.

These options may mean your data might be nuked.
