type: Opaque
data:
  authToken: <AUTH_TOKEN_ENCODED>

Multiple Authorization Keys

You can configure multiple authorization tokens inside the secret. These tokens can contain any string value, and can be used as a human-readable identifier to reference the auth token.

Here, line 8 specifies the second key, authkey2.

apiVersion: v1
kind: Secret
metadata:  
  name: kfuse-auth-ingest
type: Opaque
data:
  authkey1: <AUTH_TOKEN_ENCODED>
  authkey2: <AUTH_TOKEN_ENCODED2>

Remember to update the custom-values.yaml file to include following in the ingester config section:

...

to enable ingestion authentication:

global:
  authConfig:
    enabled: true

Configuration of Additional Labels based on Auth Token

From Kloudfuse 2.7.2 onwards, additional labels can be configured to be attached to MELT data based on the auth token used by the incoming payload.

To configure these labels, add the following in the custom-values.yaml (replace accordingly). Take note that the same keys are used in the secret and the ingester config.

ingester:
  config:
     authKeyAdditionalLabels:
        authkey1:
          - name: label1
            value: val1
          - name: label2
            value: val2
        authkey2:
          - name: label1
            value: val3
          - name: label4
            enabled: truevalue: val4 

Restart the ingester post the auth-token changes

kubectl -n kfuse rollout restart sts ingester
