Nov 5, 2019 · Abstract. Liveness is the central topic within this contribution to our book. Auslander and van Es discuss the concept of “Liveness”. Auslander can hereby be seen to be one of the “veterans” in the study of liveness and therefore one of the central temporalities we encounter in relation to media and other performance arts. But, my need is to fetch some deployment/runtime details from k8s. for ex; in our deployment we have 3 web applications, kafka, couple of databases etc. Let us call those apps as ms-A, ms-B, ms-C. And say 2 instances of each are running. Assuming that liveness, readiness probes are configured, kubernetes now has that information. Implementing Oz Liveness detection from Oz Forensics has been a game-changer for us.
