How difficult is it to minimize the toil of cluster upgrades while increasing confidence in deploying the changes?

Even when managed, cluster upgrades are an unavoidable part of cluster maintenance, yet they can also be a source of toil, stress and outages; either when upgrading Kubernetes itself or additional cluster components. Manually testing changes in staging clusters, deploying with a high sense of uncertainty - these time consuming tasks can be mitigated with tests. Add nifty automation and cluster management efforts are reduced to a bare minimum.

Is investing in cluster tests and automation worth it? Yes! This talk shows how a team of three engineers keeps multiple clusters continuously up-to-date with minimal time investment, effort and disruptions. By leveraging the e2e-framework and Helm, everything from Istio to cluster autoscaler is tested and seamlessly managed.
