Why is my "gcloud beta run services replace" command failing?

Question

I have this YAML (with the parts in square brackets replaced with the correct content):

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: ty-platform
spec:
  template:
    spec:
      containers:
      - image: gcr.io/[project name]/endpoints-runtime-serverless:[site URL]-2020-03-20r8
        env:
          - name: ESPv2_ARGS
            value: ^++^--cors_preset=basic++--cors_allow_origin=[site]++--cors_allow_headers="Authorization"

which I try to upload with this command

gcloud beta run services replace service_replace.yaml --platform managed --region us-central1

(after having already deployed successfully with gcloud run deploy).

The command runs successfully but upon testing it's clear that the replacement has failed. Namely, the ESPv2_ARGS variable is not created or updated. What could I be doing wrong?

The service in question is an ESPv2 image for a Cloud Endpoint.

Answer 1

I tried adding your ESPv2_ARGS as-is (using an existing Cloud Run service not Endpoints) and the service's environment is updated. This appears to work-as-intended.

The prior revision of the service had no environment variables defined.

gcloud beta run services describe ${SERVICE} \
--project=${PROJECT} \
--platform=managed \
--region=${REGION} \
--format="yaml(spec.template.spec.containers[0].env)"

  null

gcloud beta run services replace service.yaml
--platform=managed \
--region=${REGION} \
--project=${PROJECT}

Done.

gcloud beta run services describe ${SERVICE} \
--project=${PROJECT} \
--platform=managed \
--region=${REGION} \
--format="yaml(spec.template.spec.containers[0].env)"

spec:
  template:
    spec:
      containers:
      - env:
        - name: ESPv2_ARGS
          value: ^++^--cors_preset=basic++--cors_allow_origin=[site]++--cors_allow_headers="Authorization"

using:

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: ...
spec:
  template:
    metadata:
      name: ...
    spec:
      containers:
      - image: ...
        env:
        - name: ESPv2_ARGS
          value: ^++^--cors_preset=basic++--cors_allow_origin=[site]++--cors_allow_headers="Authorization"

I can't attest to whether this environment variable affects ESP but, the replace command appears to work correctly.
