To TDengine

Shifu can push data from your device to a TDengine database.

Create TelemetryService Yaml file​

apiVersion: shifu.edgenesis.io/v1alpha1
kind: TelemetryService
metadata:
  name: push-endpoint-1
  namespace: devices
spec:
  telemetryServiceEndpoint: http://telemetryservice.shifu-service.svc.cluster.local
  serviceSettings:
    SQLSetting:
      serverAddress: 192.168.14.163:6041
      secret: my-secret
      dbName: shifu
      dbTable: testTable2
      dbtype: TDengine
  • telemetryServiceEndpoint is telemetry service endpoint address
  • serverAddress is the database address
  • username is your database username
  • secret is the name of the Secret stored your database username and password
  • dbName is the name of the database
  • dbTable is the table name of the database
  • dbType is the type of the database

Create the Secret​

Create a Secret named the secret field above with the username field filled by your username and the password field filled by your password.

kubectl create secret generic my-secret --from-literal=username=your_username --from-literal=password=your_password -n devices
note

If you have multiple telemetry services, you can write them in one file and split them in one file using ---.

Edit Configmap Yaml file​

# configmap.yaml
data:
  telemetries: |
    telemetries:
      device_health1:
        properties:
          instruction: status
          pushSettings:
            telemetryCollectionService: push-endpoint-1 # Edit it to the name same with TelemetryService's name

Then edit the Configmap yaml file and make sure that the telemetryCollectionService value is the same as the name of the telemetry service you created in the previous step.

deploy deviceShifu again​

Then you need to deploy deviceShifu again so that the telemetry will push raw data to the telemetry service and publish it to your TDengine database.
