Increase File Size - API Gateway Ingress

Increasing the Max File upload size limit on the CX solution, 2-tiered changes will be required

At the API gateway ingress layer
per API gateway route

APISIX Ingress

Edit the helm-values/apisix-custom-values.yaml and locate the YAML hierarchy dataPlane.ingress.annotations and add these annotations

CODE

  annotations:
    # Set it the max + 1 to allow max file size
    nginx.ingress.kubernetes.io/proxy-body-size: "6m"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "600s"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "600s"
    nginx.ingress.kubernetes.io/proxy-connect-timeout: "60s"

update the deployment of API gateway by

CODE

helm upgrade --install --namespace ef-external --values helm-values/apisix-custom-values.yaml apisix expertflow/apisix --version 4.2.2

you can verify these implementations in API gateway ingress by describing the ingress annotations and look at the annotations object.

CODE

k -n ef-external get ingress apisix-data-plane -o yaml

APISIX Routes Customization

Please add in the relevant route in apisix values.yaml file before installing the solution . Example given below allows the max size of 5MB.

CODE

plugin:
  client-control:
  enable: true
  config: { max_body_size: 6291456 }

However, if the solution is already deployed, run the same helm upgrade command as used while installing the solution.

Examples

update the apisix-custom-values.yaml, set the max_body_size under plugins to the required file-size, by default it's set to 6 MB, which will allow max-size of 5.9 MB,
