| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Kubernetes, a container operations management system, has a mechanism for automatically recovering from failures by maintaining the desired state declared by the cluster administrator. This declarative configuration management method is achieved by having multiple controllers autonomously change and adjust the resources they are responsible for at the cluster management layer, called the control plane. However, there is no method to observe these cascading changes efficiently, and it is not easy to identify to which resource the change propagates and which part of the change propagation takes time. In this study, we propose a novel method to trace changes across components by adding an identifier called a update process ID to the metadata of an object that holds the current or desired state and having a controller that observes changes in that object and propagates that information to the next object. In particular, we addressed the challenges arising from the declarative configuration management characteristic of the control plane by using a method that merges change identifiers. | |
