I want to increase size of post body of each request in Ingress. So I add the

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

in yaml file ingress(in view/edit yaml file of rancher) but it doesn’t work. When I get the describe of ingress with kubectl I dont see the added annotation but i see the new added mapping.
Hereis the configs:

YAML file:

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: 198.100.101.172
 - ip: 198.100.101.173
 - ip: 198.100.101.61

describe result:

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

Amendment of the ingress objects in K8s sometimes misbehave, so it's recommended to re-create rather than edit.

If it still didn't work, try to set this value globally for all ingress rules using a configmap

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