Kubernetes GKE ingress-nginx loki grafana prometheus安装问题.<

Question

我正在尝试在Google Kubernetes Engine AKA GKE上获得一个新的集群设置。我正在使用helm并添加到仓库ingress-nginx https://kubernetes.github.io/ingress-nginx和grafana https://grafana.github.io/helm-charts

我一直在遵循这个指南，但我无法访问内部ip或使入口工作到我可以看到仪表板的地方。然后我尝试了这个指南，使用他们的头盔部署Loki Stack (Loki, Promtail, Grafana, Prometheus)与持久的卷声明。

这与打开端口8443相结合，我仍然得到503错误。我做了这个入口:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-resource
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/use-regex: "true"
spec:
rules:
- http:
paths:
- path: /pro
pathType: Prefix
backend:
service:
name: loki-prometheus-server
port:
number: 9090
- path: /graf
pathType: Prefix
backend:
service:
name: loki-grafana
port:
number: 3000

我尝试了许多不同的端口，包括80，但都没有成功。

loki-prometheus-server服务:

Name:              loki-prometheus-server
Namespace:         ingress-nginx

Endpoints:         10.***:9090
Session Affinity:  None
Events:            <none>

loki-grafana服务:

Name:              loki-grafana
Namespace:         ingress-nginx
Labels:            app.kubernetes.io/instance=loki
app.kubernetes.io/managed-by=Helm

meta.helm.sh/release-name: loki
meta.helm.sh/release-namespace: ingress-nginx
Selector:          app.kubernetes.io/instance=loki,app.kubernetes.io/name=grafana
Type:              ClusterIP
IP Families:       <none>
IP:                10.***
IPs:               10.***
Port:              service  80/TCP
TargetPort:        3000/TCP
Endpoints:         10.***:3000
Session Affinity:  None
Events:            <none>

Step by Step:

在gcloud上创建新的集群:

1. GKE标准
2. 缺省池→→节点机器类型:e2-small
3. 缺省池→安全→允许完全访问所选择的所有云api
4. 。

连接控制台或云shell

:

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
kubectl create namespace ingress-nginx
helm install ingress-nginx ingress-nginx/ingress-nginx --namespace ingress-nginx

到目前为止一切都很正常。

进入VPC网络->防火墙→在Protocols/ports中找到带有80443的那个然后加上8443

安装洛基:

helm upgrade --install loki grafana/loki-stack --namespace ingress-nginx  --set grafana.enabled=true,prometheus.enabled=true,prometheus.alertmanager.persistentVolume.enabled=false,prometheus.server.persistentVolume.enabled=false,loki.persistence.enabled=true,loki.persistence.storageClassName=standard,loki.persistence.size=5Gi

一切似乎仍然很好，但如果我去我的外部负载均衡器我得到404 not found/nginx

我添加了这个入口:

使用kubectl apply -f ingress.yml -n ingress-nginx

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-resource
annotations:
kubernetes.io/ingress.class: "nginx"
prometheus.io/scrape: "true"
spec:
rules:
- http:
paths:
- path: /pro
pathType: Prefix
backend:
service:
name: loki-prometheus-server
port:
number: 80
- path: /graf
pathType: Prefix
backend:
service:
name: loki-grafana
port:
number: 80

并得到一个404页没有找到的文本在/pro然后重定向到/login，在/graf

显示404 not found nginx页面我做错了什么?

Answer 1

Running:

helm upgrade ingress-nginx ingress-nginx/ingress-nginx --namespace ingress-nginx  --set controller.metrics.enabled=true --set-string controller.podAnnotations."prometheus.io/scrape"="true" --set-string controller.podAnnotations."prometheus.io/port"="10254"

并且使用这个入口我能够使它工作:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-resource
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/use-regex: "true"
nginx.ingress.kubernetes.io/ssl-redirect: "false"
nginx.ingress.kubernetes.io/rewrite-target: /$1
prometheus.io/port: "10254"
prometheus.io/scrape: "true"
spec:
rules:
- http:
paths:
- path: /?(.*)
pathType: Prefix
backend:
service:
name: loki-grafana
port:
number: 80
