Managing containerized workloads, such as by Kubernetes, provides a robust and expandable platform. Kubernetes high-availability (HA) mode provides additional safeguards against failure that allows services to be maintained without interruption in the event of a partial system or network failure. However, Kubernetes requires an odd number of master nodes (e.g., three) in order to be able have a quorum and maintain certain operations (e.g., election of a leader). In the event a master node loses functionality, the remaining master nodes are unable to have a quorum. System and methods are provided to convert a worker-only node into a master node in order to reestablish a quorum. Once functionality is restored, the converted master is reverted back to a worker-only node and the restored master, and remaining masters, maintain the quorum.
A method, comprising:
A system, comprising:
A non-transitory computer-readable medium comprising a set of instructions stored therein which, when executed by a processor, causes the processor to manage a worker node by:
