Daemonset for updating all nodes

[laurijssen]

In case of large clusters updating the cifs script becomes tedious, I have created a daemonset for this. Its very basic but it updates cifs script on every host every 2 hours. Maybe include it in repository and update it to make the install procedure a container itself?
