Add resource requests for system components
Set resource requests for system pods to guarantee at least some amount of resources. This prevents them from being starved of CPU/memory when running alongside resource intensive workloads in the cluster and gives them a higher quality of service class. metrics-server: 100m/200Mi recommended for up to 100 node clusters. https://github.com/kubernetes-sigs/metrics-server#scaling openstack-cloud-controller-manager: 200m CPU taken from example manifests. kubernetes-dashboard: 100m/100Mi taken from helm chart defaults. heapster: 100m/128Mi taken from helm chart defaults. influxdb: 100m/256Mi taken from influx helm chart defaults. grafana (for influxdb): 100m/200Mi same as monitoring grafana. ingress-traefik: 100m/50Mi taken from helm chart defaults. cluster-autoscaler: 100m/300Mi taken from helm chart defaults. csi-cinder-nodeplugin: 25m CPU on both containers to ensure Burstable QoS class. csi-cinder-controllerplugin: 20m CPU on all containers to ensure Burstable QoS class. tiller-deploy: 25m CPU to ensure it can always handle the readiness probe. octavia-ingress-controller: 50m CPU, just a guess really.
