Recently, cloudResourceSyncManager was implemented which continuously fetched node addresses from cloud providers. Kubelet then received node addresses from the cloudResourceSyncManager. At the time of node registration or kubelet start, kubelet fetches node addresses in a blocking loop from cloudResourceSyncManager. The issue was that cloudResourceSyncManager was not started before kubelet had started fetching node addresses from it for the first time, and due to this, kubelet got stuck in the blocking loop and never returned. It caused node failures at network level, and no node could be registered. Also as kubelet blocked early, the cloudResourceSyncManager never got a chance to start.
Solution: CloudResourceSyncManager is now started early in the kubelet startup process so that kubelet does not get blocked on it and cloudResourceSyncManager is always started.
