4. 卸载
powershell 复制代码 
$ helm uninstall prometheus -n prometheus
release "prometheus" uninstalled

kubectl delete pod -n prometheus `kubectl get pod -n prometheus |awk 'NR>1{print $1}'` --force
kubectl patch ns prometheus -p '{"metadata":{"finalizers":null}}'

$ kubectl delete ns prometheus --force
Warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
namespace "prometheus" force deleted

二、使用 Helm 安装 Grafana

1. 配置源

地址：https://artifacthub.io/packages/helm/grafana/grafana

powershell 复制代码 
$ helm repo add grafana https://grafana.github.io/helm-charts
"grafana" has been added to your repositories

$ helm repo update grafana
Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "grafana" chart repository
Update Complete. ⎈Happy Helming!⎈

$ helm search repo grafana/grafana

2. 安装 grafana
powershell 复制代码 
$ helm install grafana grafana/grafana -n grafana --create-namespace
NAME: grafana
LAST DEPLOYED: Tue Jul 16 06:01:14 2024
NAMESPACE: grafana
STATUS: deployed
REVISION: 1
NOTES:
1. Get your 'admin' user password by running:

   kubectl get secret --namespace grafana grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo


2. The Grafana server can be accessed via port 80 on the following DNS name from within your cluster:

   grafana.grafana.svc.cluster.local

   Get the Grafana URL to visit by running these commands in the same shell:
     export POD_NAME=$(kubectl get pods --namespace grafana -l "app.kubernetes.io/name=grafana,app.kubernetes.io/instance=grafana" -o jsonpath="{.items[0].metadata.name}")
     kubectl --namespace grafana port-forward $POD_NAME 3000

3. Login with the password from step 1 and the username: admin

最终自定义的参数执行：

powershell 复制代码 
$ helm install grafana grafana/grafana -n grafana --create-namespace --set service.type=NodePort --set service.nodePort=31830

$ kubectl get svc -n grafana
