在路径级别应用nginx-ingress注释 [英] Apply nginx-ingress annotations at path level

问题描述

我们正在从传统的nginx部署迁移到kubernetes的nginx-ingress控制器.我正在尝试在location级别应用设置，但是看不到如何使用注释.

We are migrating from a traditional nginx deployment to a kubernetes nginx-ingress controller. I'm trying to apply settings at a location level, but can't see how to do so with annotations.

例如，我们有:

server {
  listen 80;
  server_name example.com;

  location /allow-big-uploads {
    client_max_body_size 100M;
    ...
  }
}

然后我们将其翻译为:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: web-ingress
  annotations:
    nginx.ingress.kubernetes.io/proxy-body-size: 100m <-- this now applies globally
spec:
  rules:
    - host: example.com
      http:
        paths:
          - path: /allow-big-uploads
            backend:
              serviceName: example-svc
              servicePort: 5009

在path部分下添加该注释似乎无效.我想念什么吗?

Adding that annotation under the path section doesn't seem to work. Am I missing something?

推荐答案

女用产品规范在较低级别不包含该功能.

Annotations can only be set on the whole kubernetes resource, as they are part of the resource metadata. The ingress spec doesn't include that functionality at a lower level.

如果您正在寻找更复杂的设置，则 traefik 已构建了服务.缺点是定义与其他入口控制器不兼容.

If you are looking for more complex setups, traefik have built a custom resource definition for their ingress controller that allows more configuration per service. The downside is the definition is not compatible with other ingress controllers.
