Increase File Size - APISIX Ingress

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

at the apisix ingress layer
per apisix route

APISIX Ingress

Edit the helm-values/apisix-custom-values.yaml and locate the YAML heirarchy 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 apisix 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 apisix 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 apisixRoute in values.yaml file before installing the solution . Example given below allows the max size of 5MB.

CODE

         customPlugins:
            - name: client-control
              enable: false
              config:
                max_body_size: 5242880

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

Examples

update the ef-cx-custom-values.yaml

CODE

unified-admin:
   apisixRoutes:
      # Route 1: Main /unified-admin/* path
      - nameSuffix: "main"

        backendServicePort: 3000
        plugins:
          enableAuth: false

                max_body_size: 5242880

For Agent-Desk, edit the cx-agent-desk-custom-values.yaml file and change as per below

CODE

unified-agent:
   apisixRoutes:
     # Route 1: Main application path
     - nameSuffix: "main"
       enabled: true
       priority: 0 # Default priority
       paths: ["/unified-agent", "/unified-agent/*"] # Matches /unified-agent/ and everything after
       backendServicePort: 80
       plugins:
         enableAuth: false      # Assumed: Main application endpoints require auth
         enableRewrite: true   # Corresponds to rewrite-target removing /unified-agent
         # rewriteStripPrefix: true is implied by enableRewrite: true unless overridden
         enableCors: true      # From ingress annotations
         customPlugins:
            - name: client-control
              enable: false
              config:
                max_body_size: 5242880

     # Route 2: Assets path
     - nameSuffix: "assets"
       enabled: true
       priority: 0 # Same priority should be fine as paths are distinct prefixes
       paths: ["/assets/*"]    # Matches /assets/* directly
       backendServicePort: 80
       plugins:
         enableAuth: false     # Assumed: Assets typically don't require auth
         enableRewrite: false  # No rewrite annotation was present for assets ingress
         enableCors: true      # From ingress annotations
         customPlugins:
            - name: client-control
              enable: false
              config:
                max_body_size: 5242880
