![]() v0.3.0 is the latest version of metrics-server, and brings a number of internal stability improvements as well as some bugfixes and features. NB: this currently disables Kubelet auth entirely, since this setup needs to work on GKE for the tests, and GKE doesn't support delegated Kubelet auth yet. When that's rectified, we can switch this over to use secure options. |

Metrics Server
Metrics Server exposes core Kubernetes metrics via metrics API.
More details can be found in Core metrics pipeline documentation.
Troubleshooting
Metrics Server supports up to 30 pods per cluster node. In clusters where there are more running pods, Metrics Server may be throttled or fail with OOM error. Starting with Kubernetes 1.9.2, Metrics Server resource requirements may be overwritten manually. Learn more about Addon Resizer configuration
Important notices
Decreasing resource requirements for cluster addons may cause system instability. The effects may include (but are not limited to):
- Horizontal Pod Autoscaler not working
kubectl top
not working (starting with Kubernetes 1.10)
Overwritten configuration persists through cluster updates, therefore may cause all effects above after a cluster update.
