413 request entity too large

Is this a BUG REPORT or FEATURE REQUEST? (choose one): Bug

I am trying to increase the max post size with the ingress controller. We are using the mandatory.yaml from this repo. When I attempt to add the following, it has no affect. Can someone please explain how to make this change? I want to apply this globally in the ingress controller.

kind: ConfigMap
apiVersion: v1
metadata:
  name: nginx-configuration
  namespace: ingress-nginx
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
  annotations:
    nginx.ingress.kubernetes.io/proxy-body-size: 10m

If this is a FEATURE REQUEST, please:

• Describe in detail the feature/behavior/change you'd like to see.

Closing. Please check https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#custom-max-body-size

@aledbf It doesn't work. I have already looked at this. I am asking for support on figuring out why it isn't working.

[aledbf]

I want to apply this globally in the ingress controller.

If you want to change this globally you need to modify the configuration configmap https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/#proxy-body-size

Once you change that you can verify the new value using something like
kubectl exec -n ingress-nginx <ingress pod> cat nginx.conf|grep client_max_body_size

@aledbf in my original text above, do I have this applied in the correct location? When I then issue kubectl apply -f mandatory.yaml, it doesn't seem to redeploy in my cluster.

in my original text above, do I have this applied in the correct location?

No. Annotations are valid in Ingress objects.

You should have something like:

kind: ConfigMap
apiVersion: v1
metadata:
  name: nginx-configuration
  namespace: ingress-nginx
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
data:
  proxy-body-size: 10m

[rwmajor2]

@aledbf Ok, this now works. We need to update the documentation on this subject, because it is not clear exactly the correct global configuration like you gave me above. A good example would be useful.

[aledbf]

@rwmajor2 can you be more explicit? What do you want to see in the docs?

Pull requests are welcome :)

Adding the annotation worked just fine for me:

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: my-app-name
  namespace: my-namespace
  annotations:
    kubernetes.io/ingress.class: "nginx"
    [...]
    nginx.ingress.kubernetes.io/proxy-body-size: 16m
