Google K8S Engine. Monitoring with Prometheus and Grafana. Using Prometheus Operator by CoreOS
First, we need to configure kubectl.
gcloud container clusters get-credentials <cluster_name> --zone <cluster_zone> --project <project_name>kubectl create serviceaccount dashboard -n default
kubectl create clusterrolebinding dashboard-admin -n default \
--clusterrole=cluster-admin \
--serviceaccount=default:dashboard
kubectl get secret $(kubectl get serviceaccount kube-system:kubernetes-dashboardkubernetes-dashboard -o jsonpath="{.secrets[0].name}") -o jsonpath="{.data.token}" | base64 --decode
kubectl create clusterrolebinding myname-cluster-admin-binding \
--clusterrole=cluster-admin \
[email protected]
kubectl get deploy -n monitoring
kubectl cluster-info
kubectl describe services
kubectl get ingress grafana -n monitoring
kubectl get service
kubectl --namespace=kube-system get all
kubectl --namespace=kube-system describe service grafana-service
