+++ This bug was initially created as a clone of Bug #1885223 +++ The last master HEAD panics: ``` ./cluster-capacity --kubeconfig ~/.kube/config --podspec examples/pod.yaml panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=0x16daa79] goroutine 1 [running]: sigs.k8s.io/cluster-capacity/vendor/k8s.io/component-base/logs.(*Options).Get(...) /go/src/sigs.k8s.io/cluster-capacity/cmd/hypercc/main.go:42 +0x2f ```
Verified bug by cloning the upstream repo and i see that there is no panic. Below are the steps followed to verify the bug. 1) clone repo https://github.com/kubernetes-sigs/cluster-capacity 2) cd cluster-capacity/ 3) make build go build -o hypercc sigs.k8s.io/cluster-capacity/cmd/hypercc ln -sf hypercc cluster-capacity ln -sf hypercc genpod 4) ./cluster-capacity --kubeconfig /home/knarra/Downloads/kubeconfig_46O --podspec=examples/pod.yaml I1006 21:59:49.361591 19459 registry.go:173] Registering SelectorSpread plugin I1006 21:59:49.361630 19459 registry.go:173] Registering SelectorSpread plugin 16 [knarra@knarra cluster-capacity]$ ./cluster-capacity --kubeconfig /home/knarra/Downloads/kubeconfig_46O --podspec=examples/pod.yaml --verbose I1006 22:01:37.252776 19722 registry.go:173] Registering SelectorSpread plugin I1006 22:01:37.252802 19722 registry.go:173] Registering SelectorSpread plugin small-pod pod requirements: - CPU: 150m - Memory: 100Mi The cluster can schedule 16 instance(s) of the pod small-pod.
