尝试使用Ingress重写Grafana的url [英] Trying to rewrite url for Grafana with Ingress

问题描述

在我的kubernetes集群中，我想进行监视，所以我安装了grafana.

In my kubernetes cluster I would like to do monitoring so I installed grafana.

我想以http://example.com/monitoring的形式访问grafana仪表板，因此我尝试将其包含在我的入口配置中

I would like to access the grafana dashboard as http://example.com/monitoring, so I tried to include this in my ingress configuration

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: example-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
  rules:
  - host: example.com
  http:
    paths:
    - path: /monitoring/(.*)
    backend:
     serviceName: grafana
     servicePort: 80

想法是也要在其中添加其他路径，例如网站的/.

The idea is to add other paths there as well, for example / for the website.

我注意到Grafana将http://example.com/monitoring重定向到http://example.com/login.当然应该是http://example.com/monitoring/login.解决此问题的首选方法是什么.可以用ingress完成吗?还是我应该以某种方式告诉Grafana它在/monitoring路径后面(如果可能)?

I noticed that Grafana redirects http://example.com/monitoring to http://example.com/login. Of course this should have been http://example.com/monitoring/login. What would be the preferred way to fix this. Can it be done with ingress or should I somehow tell Grafana that it is behind a /monitoring path (if possible)?

我已经使用此.

更新:我已经按照以下建议修改了grafana图表的文件values.yaml

UPDATE: I've modified as suggested below the grafana chart's file values.yaml as follows

grafana.ini:
  server:
    domain: example.com
    root_url: http://example.com/monitoring/

现在我得到了:

还有我用来安装grafana的heml命令:

And the heml command I use to install grafana:

$> helm install stable/grafana -f values.yaml --set persistence.enabled=true --set persistence.accessModes={ReadWriteOnce} --set persistence.size=8Gi -n grafana

推荐答案

这是HTTP反向代理背后的服务的常见问题.幸运的是，Grafana提供了一种让它知道它在后面运行的上下文路径的方法.

This is a common problem with services that are behind an HTTP reverse-proxy. Luckily, Grafana offers a way to let it know the context path it is running behind.

在grafana.ini(最有可能通过ConfigMap提供给其Kubernetes部署)中，您需要指定如下变量:

In grafana.ini (which is most possibly supplied via a ConfigMap to its Kubernetes deployment), you need to specify the variables like the following:

[server]
domain = example.com
root_url = http://example.com/monitoring/
