Vision user rules

Goal​

Deploy three NatsUserRule objects. The vision inspection Application references them by name. Nothing from the plant example is required.

  • frame-publisher lets frame-generator publish vision.wafers.>.
  • vision-detector lets object-detector subscribe to wafers and publish vision.inspections.>.
  • snapshot-consumer lets snapshot-service subscribe to inspections.

The file is deploy/steps/11-nats-user-rules-vision.yaml.

YAML​

frame-publisher
apiVersion: datasance.com/v3
kind: NatsUserRule
metadata:
  name: frame-publisher
spec:
  description: frame-generator - publish wafer map metadata (in-account)
  maxSubscriptions: -1
  maxPayload: -1
  maxData: -1
  bearerToken: false
  allowedConnectionTypes:
    - STANDARD
  pubAllow:
    - vision.wafers.>
vision-detector
apiVersion: datasance.com/v3
kind: NatsUserRule
metadata:
  name: vision-detector
spec:
  description: object-detector - subscribe wafer frames, publish inspections (in-account)
  maxSubscriptions: -1
  maxPayload: -1
  maxData: -1
  bearerToken: false
  allowedConnectionTypes:
    - STANDARD
  pubAllow:
    - vision.inspections.>
  subAllow:
    - vision.wafers.>
snapshot-consumer
apiVersion: datasance.com/v3
kind: NatsUserRule
metadata:
  name: snapshot-consumer
spec:
  description: snapshot-service - subscribe inspections for HTTP snapshot API (in-account)
  maxSubscriptions: -1
  maxPayload: -1
  maxData: -1
  bearerToken: false
  allowedConnectionTypes:
    - STANDARD
  subAllow:
    - vision.inspections.>

The repo file also sets connection limits. Deploy that file. These blocks show the subject lists.

SubjectWho uses it
vision.wafers.>frame-generator publishes. object-detector subscribes.
vision.inspections.>object-detector publishes. snapshot-service subscribes.

Subjects are vision.wafers.> and vision.inspections.>. Older demos used vision.frames.* and vision.detections.*.

Deploy​

potctl deploy -f deploy/steps/11-nats-user-rules-vision.yaml

What you should see​

potctl get nats-user-rules

frame-publisher, vision-detector, and snapshot-consumer are listed. No microservices are running yet.

Common mistakes​

Deploying the Application before these rules exist. The Application names them.

These rules can exist before the vision account, or you can deploy them with it. The Application must come after both.
