kube-node-tuning¶
kube-node-tuning is aimed at kernel tuning by kubernetes. It's useful to:
- High performance application
- Large Scale Cluster
- Network Tuning
Quick Start¶
export VERSION=v0.3.1
helm repo add kube-node-tuning https://kubean-io.github.io/kube-node-tuning/
helm install -n kube-node-tuning kube-node-tuning kube-node-tuning/kube-node-tuning --version $VERSION --create-namespace
Tip
If the machine is in China, you should following by: quick-start-in-china
The kernel's sysctl settings are applied to the node at /etc/99-kube-node-tuning.conf.
Check if the settings are applied by the following command. SSH to the node of cluster
Configuration¶
# Change the config
kubectl -n kube-node-tuning edit cm/kube-node-tuning-config -o yaml
# Restart the DaemonSet

Roadmap¶
- Different OS Support. (Ubuntu, CentOS, RHEL, etc.)
- Multi profile
- Operator instead of Daemonset
