Signals Data Factory - How to restart SDF service?

This article describes how to restart Signals Data Factory (SDF) service.

On each SDF node, one at a time, run the following commands:

       1. First, 'drain' the node (this safely evicts all pods on a node):

      kubectl drain <Node IP Address> --ignore-daemonsets --delete-local-data

      2. When 'drain' command completes, restart/reboot the node.

      3. When the node comes back online, run the following command to resume scheduling new pods:

      kubectl uncordon <Node IP Address>

4. Wait until all pods on this node are in 'running' state.

Important: Perform all the steps above on each node without moving to next node until current node is back online and all pods are back in 'running' state.
