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.
