• 413 Request Entity Too Large in nginx k8s ingress

  Apr 19, 2020 · 1 min read

  I wanted to enable a file upload. Whenever I was uploading I received the error code “413 Request Entity Too Large” from the nginx ingress controller in kubernetes. I found the solution here. Use the following annotation to allow unlimited upload size:

  nginx.ingress.kubernetes.io/proxy-body-size: "0"
  

  In my case, the ingress file definition now looks like this:

  ---
  apiVersion: networking.k8s.io/v1beta1 # for versions before 1.14 use extensions/v1beta1
  kind: Ingress
  metadata:
    name: my-name
    namespace: my-namespace
    annotations:
      nginx.ingress.kubernetes.io/rewrite-target: /$1
      nginx.ingress.kubernetes.io/proxy-body-size: "0"
  spec:
    # The specs, omitted for readability
