Upgrade is performed by updating node configuration (node by node, service by service), watching internal resource state to get new configuration version and verifying that pod with matching version successfully propagated to the API server state and pod is ready. Process is similar to the rolling update of the DaemonSet. Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
