# Operational guide for worker nodes

## Replace worker node
|
|
In order to change the instance type or in genernal replace worker nodes do:
|
|
|
|
* (optional) Update the launch configuration of the worker group
|
|
|
|
* Make sure there is enough capacity in the cluster to handle all pods being evicted for the node
|
|
|
|
* `kubectl drain --ignore-daemonsets node_name`
|
|
will evict all pods except DaemonSets. In case there are pods with local storage review each affected pod. After being sure no important data will be lost add `--delete-local-data` to the original command above and try again.
|
|
|
|
* Terminate instance matching *node_name*
|
|
|
|
The new instance should take over the previous node_name assuming only node is being replaced at a time and automatically join and replace the previous node.
