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 onkrib/operate-options
- command line arguments to pass to thekubectl
command for the action
Note
DRAIN NOTES: this Stage does a few things that MAY BE VERY BAD !!
- service pods are ignored for the drain operation
- --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
