amazon-web-services - prometheus-9.5.4 获取 helm status 失败

Question

我正在关注但无法理解和排除部署状态失败的原因。 https://linuxacademy.com/cp/courses/lesson/course/2205/lesson/2/module/218

curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get > /tmp/get_helm.sh
chmod 700 /tmp/get_helm.sh
DESIRED_VERSION=v2.8.2 /tmp/get_helm.sh
helm init --wait
kubectl --namespace=kube-system create clusterrolebinding add-on-cluster-admin --clusterrole=cluster-admin --serviceaccount=kube-system:default
helm ls
cd ~/
git clone https://github.com/kubernetes/charts
cd charts
git checkout efdcffe0b6973111ec6e5e83136ea74cdbe6527d
cd ../
vi prometheus-values.yml
prometheus-values.yml:

alertmanager:
    persistentVolume:
        enabled: false
server:
    persistentVolume:
        enabled: false
Then run:

helm install -f prometheus-values.yml charts/stable/prometheus --name prometheus --namespace prometheus
vi grafana-values.yml
grafana-values.yml:

adminPassword: password
Then run:

helm install -f grafana-values.yml charts/stable/grafana/ --name grafana --namespace grafana
vi grafana-ext.yml
grafana-ext.yml:

kind: Service
apiVersion: v1
metadata:
  namespace: grafana
  name: grafana-ext
spec:
  type: NodePort
  selector:
    app: grafana
  ports:
  - protocol: TCP
    port: 3000
    nodePort: 8080
Then run:

kubectl apply -f grafana-ext.yml
You can check on the status of the prometheus and grafana pods with these commands:

kubectl get pods -n prometheus
kubectl get pods -n grafana
When setting up your dastasource in grafana, use this url:

http://prometheus-server.prometheus.svc.cluster.local

在 2 个不同的环境中遇到相同的问题

1. 在 aws 中运行的 k8s 集群状态为失败

   $ kubectl 描述部署普罗米修斯 -n 普罗米修斯

来自服务器的错误 (NotFound): deployments.extensions "prometheus" not found

$ helm ls --all

2. 在 hyper V 上运行的 k8s 集群

   admin1@POC-k8s-master:~/poc-cog$ helm init --wait

       $HELM_HOME has been configured at /home/admin1/.helm.
       Error: error installing: the server could not find the requested resource
