Kafka Log: Delegated tokens authentication - Plugin

Delegated tokens authentication

Use delegated tokens generated in Kafka to authenticate the Kafka Log plugin.

Prerequisites

Environment variables

KAFKA_TOPIC: The name of your Kafka topic.
TOKEN_ID: The tokenID for your delegated token.
TOKEN_HMAC: The token-hmac for your delegated token.

Set up the plugin

Add this section to your declarative configuration file:

_format_version: "3.0"
plugins:
  - name: kafka-log
    config:
      topic: ${{ env "DECK_KAFKA_TOPIC" }}
      authentication:
        strategy: sasl
        mechanism: SCRAM-SHA-256
        user: ${{ env "DECK_TOKEN_ID" }}
        password: ${{ env "DECK_TOKEN_HMAC" }}
        tokenauth: true

Make the following request:

curl -i -X POST http://localhost:8001/plugins/ \
    --header "Accept: application/json" \
