Kubernetes Ingress + Apache气流 [英] Kubernetes Ingress + Apache airflow

问题描述

你能帮我吗?

我正在尝试在vpc中的Kubernetes(AWS)中启动Apache airflow. 我正在使用头盔稳定/气流7.1.1

I'm trying to start Apache airflow in Kubernetes (AWS), in vpc. I'm using helm stable/airflow 7.1.1

一切正常.但是要访问Web界面，我需要通过入口ELB公开它. 我有这个设置. 气流规则如下所示:

Everything starts ok. But to get access to web interface I need to expose it via ingress ELB. I have this setup. The rule for airflow looks like this:

apiVersion: v1
items:
- apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    annotations:
      kubernetes.io/ingress.class: nginx
      nginx.ingress.kubernetes.io/connection-proxy-header: upgrade
      nginx.ingress.kubernetes.io/rewrite-target: /$2
    creationTimestamp: "2020-05-29T14:52:54Z"
    generation: 31
    labels:
      app.kubernetes.io/instance: airflow-dev-web
      app.kubernetes.io/managed-by: Tiller
      app.kubernetes.io/name: airflow-dev-web
      app.kubernetes.io/version: "1.0"
      helm.sh/chart: web-service-0.1.0
    name: airflow
    namespace: dev
    resourceVersion: "45272238"
    selfLink: /apis/extensions/v1beta1/namespaces/dev/ingresses/airflow
    uid: 64f276ad-b51f-4551-8078-51a7184b04b4
  spec:
    rules:
    - host: public.host.com
      http:
        paths:
        - backend:
            serviceName: airflow-dev-web
            servicePort: 8080
          path: /airflow(/|$)(.*)
  status:
    loadBalancer:
      ingress:
      - ip: <public_ip>

我可以用/health打开/health:

I can open the /health with is OK:

https://public.host.com/airflow/health

但是当我打开管理Web端点时:

But when I open admin web endpoint:

https://public.host.com/airflow/admin

我有许多未重写的url-它们指向的是public.host.com，而不是public.host.com/airflow/....就像这样:

I have many not rewritten urls - they are pointing to public.host.com but not to public.host.com/airflow/ .... Like this:

URL: https://public.host.com/admin/admin/bootstrap/bootstrap3/css/bootstrap-theme.min.css?v=3.3.5
Status: 404 Not Found

我发现我需要对反向代理进行特殊设置.像这里:

I found that I need special setup for reverse proxy.. Like here:

https://airflow.readthedocs.io/en /stable/howto/run-behind-proxy.html

但是我找不到如何使用Ingress ....:((

But I cannot find how to do this using Ingress.... :((

请帮助我！

推荐答案

不再是实际的. 使用以下方法赢得了它:

Is not actual anymore. Have won it using:

nginx.ingress.kubernetes.io/server-snippet: |
          proxy_set_header Host $host;
          proxy_redirect off;
          proxy_http_version 1.1;
          proxy_set_header Upgrade $http_upgrade;
          proxy_set_header Connection "upgrade";

还需要设置气流:

ENABLE_PROXY_FIX: "True"

和

baseUrl: "http://local.airflow/airflow"
