I dunno, Kubernetes has a query language, it's called jq. As in, kubectl get pods -A -ojson | jq -r '.items[] | ...'. Cyphernetes seems simpler perhaps but it's not the 10x improvement I need to switch and introduce a new dependency.
$ kubectl logs -n foo $(kubectl get pod -n foo | awk '/Running/{print $1}')
I don't see how their queries can be more efficient than hitting the kube-apiserver multiple times, unless they have something that lives clusterside observing lifecycle events for all CRDs and answering queries with only one round-trip instead of multiple.
Or maybe they're selling "no nested kubectl queries" as an experience feature, saying that a query language is more ergonomic than bash command redirection. My brain has been warped into the shape of the shell, for better or for worse, so it's not a selling point for me.
