Debezium UI

WEB UI SAMPLE

Debezium is an open source distributed platform for change data capture (CDC).

This repository contains a web-based UI for Debezium, allowing to configure Debezium connectors in an intuitive way, control their lifecycle, and more. The Debezium UI is a standalone web application, which connects to Kafka Connect via its REST API.

This project is under active development, any contributions are very welcome.

Prerequisites

Debezium UI needs a properly running Debezium instance version 1.4.0.Beta1 or newer and running DB instances, depending on what connectors you are going to use (Postgres, Mongo DB, MySQL, etc).

DEV Infrastructure with Docker-Compose

You can setup a running DEV infrastructure with Zookeeper, Kafka, Debezium, Postgres and Mongo DB using docker-compose:

## optionally make sure you have the latest images:
$ docker-compose pull

Pulling dbzui-zookeeper ... done
Pulling dbzui-db-mongo  ... done
Pulling dbzui-db-mysql  ... done
Pulling debezium-ui_mongo-initializer_1 ... done
Pulling dbzui-kafka     ... done
Pulling dbzui-db-pg     ... done
Pulling dbzui-connect   ... done

## start containers
$ docker-compose up -d

Creating dbzui-db-mysql  ... done
Creating dbzui-db-pg     ... done
Creating dbzui-zookeeper ... done
Creating dbzui-db-mongo  ... done
Creating debezium-ui_mongo-initializer_1 ... done
Creating dbzui-kafka     ... done
Creating dbzui-connect   ... done

Debezium UI will be available on http://localhost:8080
Kafka Connect REST API with Debezium will be available on local port 8083.
Postgres will be available on local port 65432.
MySQL will be available on local port 63306.
Mongo DB will be availaible after ~20 seconds on local port 37017 (connect via mongo -u debezium -p dbz --authenticationDatabase admin localhost:37017/inventory) Kafka will be available on local port 9092.

## later stop containers:
$ docker-compose down

Build

The entire application (UI and backend) can be built via Maven:

./mvnw clean install

The UI part is an single-page application (SPA) based on the React framework. It is packaged as JAR, whose contents are then exposed by the Quarkus-based backend application.

Backend

The UI backend is a Quarkus application located under backend. You can run it in development mode like so:

./mvnw -am -pl backend package quarkus:dev

Swagger UI can be accessed from: http://localhost:8080/swagger-ui/

UI Development

The UI frontend code is located under the ui folder. See the UI README for more information about UI development.

Run the UI as a federated module consumed by the cos-ui app

cd ui
npm install
npm run start:federate

This will run a dev server on http://localhost:3000 that will serve a federated module named debezium_ui.
