kubernetes

Collect and monitor the general performance metrics of Kubernetes.

Pre-monitoring operations

If you want to monitor the information in 'Kubernetes', you need to obtain an authorization token that can access the API Server, so that the collection request can obtain the corresponding information.

Refer to the steps to obtain token

method one:

  1. Create a service account and bind the default cluster-admin administrator cluster role

kubectl create serviceaccount dashboard-admin -n kube-system

  1. User Authorization
kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin
kubectl -n kube-system get secret | grep dashboard-admin | awk '{print $1}'
kubectl describe secret {secret} -n kube-system

method two:

kubectl create serviceaccount cluster-admin
kubectl create clusterrolebinding cluster-admin-manual --clusterrole=cluster-admin --serviceaccount=default:cluster-admin
kubectl create token --duration=1000h cluster-admin
