BentoML CORS error on loading swagger docs in k8s deployment

This is similar to https://github.com/bentoml/BentoML/issues/1909, except i am doing k8s deployment and couldn't figure out where to put bento_config.yaml stuff in k8s config. Current config

apiVersion: serving.yatai.ai/v2alpha1
kind: BentoDeployment
metadata:
  name: isleroyale
spec:
  autoscaling:
    maxReplicas: 10
    minReplicas: 2
  bento: isleroyale
  ingress:
    enabled: true
  resources:
    limits:
      cpu: 4000m
      memory: 4Gi
    requests:
      cpu: 2000m
      memory: 3Gi
  envs:
    - name: BENTOML_CONFIG_OPTIONS
      value: >-
        tracing.exporter_type=otlp

I am trying to load swagger from react app (backstage https://backstage.io/docs/features/software-catalog/) and getting cors issue - considering k8s deployment, how to enable cors?

Access to fetch at 'https://localhost:8080/isleroyale/docs.json' from origin 'http:localhost:8081' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
Solution

  • Figured out that configuration can be overridden Overriding configuration with environment variables and CORS can be enabled with http config server config with BENTOML_CONFIG_OPTIONS env variable

        envs:
      - name: BENTOML_CONFIG_OPTIONS
        value: >-
          api_server.http.cors.enabled=true
          api_server.http.cors.access_control_allow_origin=https://services.localhost.8080
          api_server.http.cors.access_control_allow_methods[0]=GET
          api_server.http.cors.access_control_allow_methods[1]=OPTIONS
          api_server.http.cors.access_control_allow_methods[2]=HEAD
