Abstract: Techniques are provided for upgrading an external distributed storage layer that provides storage services to containerized applications hosted within a container hosting platform. An operator within the container hosting platform is custom configured to orchestrate, from within the container hosting platform, the upgrade for the external distributed storage layer. Because the external distributed storage layer and the container hosting platform are separate computing environment that utilize different namespaces, semantics, operating states, and/or application programming interfaces, a cluster controller within the container hosting platform is custom configured to reformat/translate commands between the external distributed storage layer and the container hosting platform for performing the upgrade. Because the external distributed storage layer upgrade may be part of an overall upgrade that upgrades the containerized applications hosted within the container hosting platform, the operator and cluster controller provide a single upgrade orchestration point for perform both upgrades in an orchestrated manner.

Abstract: Techniques are provided for load balancing for IP failover. A backend address of a first node is identified as a routing destination to which a request is to be routed by a load balancer based upon a load balancer rule mapping a frontend address, specified by the request as a request destination, to the backend address of the first node. The request is routed to a primary network interface of the first node using the backend address. The first node has a loopback interface with an address matching the frontend address for routing the request to a destination data structure based upon the request maintaining the frontend address as the request destination. Health probes are used by the load balancer for detecting a failure of the first node in order to failover to routing requests to a second backend address of a second node.
