krib-operate

Configure consul agents.

This stage runs an Operation (drain|uncordon) on a given KRIB built Kubernetes node. You must specify action you want taken via the krib/operate-action Param. If nothing specified, the default action will be to drain the node.

In addition - you may set the following Params to alter the behavior 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

Note

DRAIN NOTES: 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.

UNCORDON NODES: typically does not require additional options
