Confluent Tools

Kafka, Zookeeper, and Confluent's command-line tools in a docker image.

Overview

This is a docker image that provides the confluent platform tools. This can be utilized to run the Kafka, Zookeeper, or Confluent tools locally without having to install them. It can also be deployed alongside Kafka & Zookeeper so one can utilize the tools in a live setting. It's also quite useful for running these tools on Windows machines.

Getting Started

Ensure you have Docker installed. Pull down the image:

docker pull devshawn/confluent-tools

Singleton mode

If you just need to run a command locally and don't need to keep the container running, you can execute commands without a background daemon container.

docker run --net=host -it --entrypoint run devshawn/confluent-tools {cmd}

For example, listing Kafka topics with local zookeeper running:

docker run --net=host -it --entrypoint run devshawn/confluent-tools kafka-topics --list --zookeeper localhost:2181

Daemon mode

The container can be run in daemon mode and act as a running machine with the tools installed. Start the container:

docker run -d --name confluent-tools --net=host devshawn/confluent-tools

The container will now be running. We set the following properties:

• -d: run container in daemon mode
• --name: set the container name
• --net=host: run container with access to localhost (i.e. kafka running locally)

Execute Single Commands

You can run single commands such as:

docker exec -it confluent-tools {cmd}

For example, listing Kafka topics with local zookeeper running:

docker exec -it confluent-tools kafka-topics --list --zookeeper localhost:2181

Executing Commands

If you're going to be running a lot of commands, it's easier to run them from inside of the container. First, open a shell inside of the container:

docker exec -it confluent-tools /bin/bash

You'll now see something such as:

bash-4.4#

From here, run commands as if they were on your local machine. For example, listing Kafka topics with a local zookeeper running:

kafka-topics --list --zookeeper localhost:2181
