Ashutosh will present the quirks of scaling up Custom Controllers - around implementing mutex, handling upgrades and best practices around versioning of the CRs. The talk is based on the experiences of running Custom Controllers in openebs project. CRs are crucial part of Kubernetes ecosystem enabling projects to put their own sauce within Kubernetes environment. Whenever it comes to access/modify a resource in the world of concurrent programming the very first thing that would come to our mind is mutexes to avoid undesired behaviours. This talk will walk through live examples of code and CR YAMLs.
