esque - an operational kafka tool.

Project description

esque - an operational Kafka tool

pypi Version Python Versions Build Status Coverage Status License: MIT

In the Kafka world nothing is easy, but esque (pronounced esk) is an attempt at it.

esque is a user-centric command line interface for Kafka administration.

Why should you care?

Some stuff is hard, and that is okay, but listing your kafka topics shouldn't be.

While adopting kafka at we noticed the immense entry barrier it poses to newcomers. We can't recount how often we wrote Slack messages asking for the script to check the status of topics or consumer groups. This is partly (but not only) due to a fragmented and unclear definition of tooling and APIs for kafka. In a wide array of administration tools, esque distances itself by striving to provide Kafka Ops for Humans, in a usable and natural way.

We feel that the goal of esque embodies the principle: “keep easy things easy, and make hard things possible”.

Installation and Usage


esque is available at and can be installed with pip install esque. esque requires Python 3.6+ to run.

SASL Support

When your cluster is secured with SASL authentication, you'll need to install our fork of pykafka since pykafka itself doesn't support it. We've opened a pull request but at the time of writing it hasn't been merged yet.

pip install -U git+

esque will also prompt you with the above command as soon as you need it in case you're not sure if you actually do.


The autocompletion scripts for bash and zsh can be generated by running esque config autocomplete.


Config Definition

When starting esque for the first time the following message will appear:

No config provided in ~/.esque
Should a sample file be created in ~/.esque [y/N]:

When answering with y esque will copy over the sample config to ~/.esque/esque_config.yaml. Afterwards you can modify that file to fit your cluster definitions.

Alternatively might just provide a config file following the sample config's file in that path.

Config Example
version: 1
current_context: local
  # This context corresponds to a local development cluster
  # created by docker-compose when running esque from the host machine.
      - localhost:9092
    security_protocol: PLAINTEXT
    schema_registry: http://localhost:8081
      num_partitions: 1
      replication_factor: 1

Config file for "apply" command

The config for the apply command has to be a yaml file and is given with the option -f or --file.

In the current version only topic configurations can be changed and specified.

It has to use the same schema, which is used for the following example:

  - name: topic_one
    replication_factor: 3
    num_partitions: 50
      cleanup.policy: compact
  - name: topic_two
    replication_factor: 3
    num_partitions: 50
      cleanup.policy: compact


To setup your development environment, make sure you have at least Python 3.6 & poetry installed, then run

poetry install
poetry run pip install -U git+
poetry shell

Pre Commit Hooks

To install pre commit hooks run:

pip install pre-commit
pre-commit install
pre-commit install-hooks

Run tests

Integration Tests

esque comes with a docker-compose based kafka stack which you can start up with make test-suite.

You can then run the integration tests against this stack with pytest tests/ --integration --local.

Alternatively you can go the fast way and just run the whole stack + integration tests in docker:

make integration-test

Unit Tests

If you only want the unit tests, just run:

make test
