Nginx.ingress.kubernetes.io/proxy-body-size 不工作

Question

我想增加 Ingress 中每个请求的帖子正文的大小。所以我添加

nginx.ingress.kubernetes.io/proxy-body-size: 8m

在 yaml 文件入口（在 Rancher 的查看/编辑 yaml 文件中）但它不起作用。当我使用 kubectl 获得入口的描述时，我没有看到添加的注释，但我看到了新添加的映射。这是配置：

YAML 文件：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    ingress.kubernetes.io/configuration-snippet: |-
      set $test_host "testdms.test.com"
      if ($host == $test_host) {
        return 301 $scheme://$test_host/webui/;
      }
    nginx.ingress.kubernetes.io/proxy-body-size: 8m
  creationTimestamp: 2018-09-11T12:19:02Z
  generation: 116
  name: test-dms
  namespace: test-dms
  resourceVersion: "95490045"
  selfLink: /apis/extensions/v1beta1/namespaces/test-dms/ingresses/test-dms
  uid: de7c4c1b-b5bc-11e8-84c0-005056bf6431
spec:
  rules:
  - host: testdms.test.com
    http:
      paths:
      - backend:
          serviceName: ingress-e5a45b0dc688c653b79d4b5942ebbe7c
          servicePort: 80
        path: /test
status:
  loadBalancer:
    ingress:
    - {}
    - ip: 198.100.101.171
    - ip: 198.100.101.172
    - ip: 198.100.101.173
    - ip: 198.100.101.61

描述结果：

Annotations:
  configuration-snippet:  set $test_host "testdms.test.com"
if ($host == $test_host) {
  return 301 $scheme://$test_host/webui/;
}

Answer 1

您需要添加引号（例如"8m"），如下所示：

nginx.ingress.kubernetes.io/proxy-body-size: "8m"

Answer 2

K8s 中入口对象的修改有时会出现错误，因此建议重新创建而不是编辑。

如果仍然不起作用，请尝试使用 configmap 为所有入口规则全局设置此值

    apiVersion: v1
    kind: ConfigMap
    metadata:
      name: nginx
      namespace: ingress-nginx
      labels:
        app: ingress-nginx
    data:
      proxy-body-size: "8m"
