Amazon Comprehend target

Send events to Amazon Comprehend

With tmctl:

tmctl create target awscomprehend --region <region> --language <language> --awsApiKey <awsApiKey> --awsApiSecret <awsApiSecret>

On Kubernetes:

Secret

apiVersion: v1
kind: Secret
metadata:
  name: aws
type: Opaque
stringData:
  AWS_ACCESS_KEY_ID: "<AWS Access Key ID>"
  AWS_SECRET_ACCESS_KEY: "<AWS Secret Access Key>"

Target

apiVersion: targets.triggermesh.io/v1alpha1
kind: AWSComprehendTarget
metadata:
  name: triggermesh-aws-comprehend
spec:
  region: us-west-1
  language: en
  awsApiKey:
    secretKeyRef:
      name: aws
      key: AWS_ACCESS_KEY_ID
  awsApiSecret:
    secretKeyRef:
      name: aws
      key: AWS_SECRET_ACCESS_KEY

This target accepts events of any type and analyzes each of the key values sentiment. It then combines the scores and returns the analysis in a response event of type io.triggermesh.targets.aws.comprehend.result.

You can test the Target by sending it an event using curl:

curl -v "10.1.215.232:8080" \
       -X POST \
       -H "Ce-Id: 536808d3-88be-4077-9d7a-a3f162705f79" \
