GitHub Workflow Status built with nix

Kafka Connect configurator tool.

Usage

This tool allows configuring Kafka Connect when running in distributed mode (which is the default mode of operation when running basically any of the containerized versions).

It allows configuring a list of connectors and keeping those configurations up-to-date.

Create a YAML file with a list of connectors:

- name: mock
  config:
    connector.class: org.apache.kafka.connect.tools.MockSinkConnector
    key.converter: "org.apache.kafka.connect.storage.StringConverter"
    value.converter: "org.apache.kafka.connect.json.JsonConverter"
    value.converter.schemas.enable: "false"
    schemas.enable: "false"
    topics.regex: "^om_[A-Za-z0-9]+(?:_[A-Za-z0-9]+)*_events$"
    errors.tolerance: "all"
    errors.retry.timeout: "30"

Run kcconf:

kcconf --kafka-connect-url http://127.0.0.1:8080 --connectors-file connectors.yaml

Pro tip: You can run kcconf in a Docker Compose setup:

version: "3.9"

services:
  # ...

  kcconf:
    image: ghcr.io/sagikazarmark/kcconf
    depends_on:
      # This is technically not necessary, because kcconf will retry connecting to Kafka Connect,
      # but if you have a health check it doesn't hurt either.
      kafka-connect:
        condition: service_healthy
    environment:
      KAFKA_CONNECT_URL: http://kafka-connect:8080
    volumes:
      - $PWD/connectors.yaml:/etc/kcconf/connectors.yaml

Development

For an optimal developer experience, it is recommended to install Nix and direnv.
