安装heapster

使用主仓库

cd /opt/kubernetes-repo/cluster/addons/cluster-monitoring/influxdb

cat <<EOF | kubectl create -f -
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:

EOF

kubectl create -f influxdb-grafana-controller.yaml
kubectl create -f grafana-service.yaml
kubectl create -f influxdb-service.yaml
kubectl create -f heapster-service.yaml
pip install jinja2
alias render_template='python -c "from jinja2 import Template; import sys; print(Template(sys.stdin.read()).render());"'
NODECOUNT=`kubectl get nodes | grep -v 'NAME'| wc -l`

heaster 资源基于动态配置

单位 Mi
metrics_memory 200 + num_nodes * 4
eventer_memory 200 + num_nodes * 0.5
sed "s/pillar.get('num_nodes', -1)/$NODECOUNT/g" heapster-controller.yaml | render_template | kubectl create -f -

使用heapster仓库

git clone https://github.com/kubernetes/heapster/ heapster-repo
cd kubernetes-repo/cluster/addons/cluster-monitoring/influxdb
