kubernetes nginx ingress server-snippet 注释没有生效

Question

我有以下 ingress.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
    name: nginx-configuration-snippet
    annotations:
        nginx.ingress.kubernetes.io/rewrite-target: /$2
        nginx.ingress.kubernetes.io/server-snippet: |
          location /base/path/v1/api/update {
              deny all;
              return 404;
            }
spec:
  rules:
    - http:
        paths:
          - path: /base/path(/|$)(.*)
            backend:
              serviceName: myApi
              servicePort: 8080

但是当我将 PUT 请求发送到/base/path/v1/api/update 而不是得到 404 时，我得到的是 500，这意味着路径可以从入口 Controller 到达。谁能帮我找出原因？

我更改为配置片段，得到的错误是:

Error: exit status 1
2020/08/06 18:35:07 [emerg] 1734#1734: location "/base/path/v1/api/update" is outside location "^/base/path(/|$)(.*)" in /tmp/nginx-cfg008325631:2445
nginx: [emerg] location "/base/path/v1/api/update" is outside location "^/base/path(/|$)(.*)" in /tmp/nginx-cfg008325631:2445
nginx: configuration file /tmp/nginx-cfg008325631 test failed

添加我自己的答案:对我有用的最终配置是:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
    name: nginx-configuration-snippet
    annotations:
        nginx.ingress.kubernetes.io/rewrite-target: /$2
        nginx.ingress.kubernetes.io/server-snippet: |
          location ~* "^/base/path/v1/api/update" {
              deny all;
              return 403;
            }
spec:
  rules:
    - http:
        paths:
          - path: /base/path(/|$)(.*)
            backend:
              serviceName: myApi
              servicePort: 8080
