# esque - an operational Kafka tool
[](https://pypi.org/project/esque/)

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 real.digital 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**”.
## Principles
* batteries included
* feature rich
* robust
* insightful
* by engineers for engineers
## Feature Overview
* Support for any type of Kafka deployment >1.2
* Display Resources (Topics, Consumer Groups, Brokers)
* Get detailed Overviews of Resources (Topics, Consumer Groups, Brokers)
* Create/Delete Topics
* Edit Topic Configurations
* Edit Consumer Offset for Topics
* SASL/SSL Support out of the box
* Consume and Produce to and from Avro and Plaintext Topics (including Avro Schema Resolution from Schema Registry)
* Context Switch (Easily Switch between pre-defined Clusters)
* Kafka Ping (Test roundtrip time to your kafka cluster)
## Command Overview
```bash
$ esque
Usage: esque [OPTIONS] COMMAND [ARGS]...
esque - an operational kafka tool.
In the Kafka world nothing is easy, but esque (pronounced esk) is an
attempt at it.

config Configuration-related options.
consume Consume messages from a topic.
create Create a new instance of a resource.
ctx List contexts and switch between them.
delete Delete a resource.
describe Get detailed information about a resource.
edit Edit a resource.
get Get a quick overview of different resources.
io Run a message pipeline.
ping Test the connection to the kafka cluster.
produce Produce messages to a topic.
set Set resource attributes.
urlencode Url-encode the given value.
```
## Installation and Usage
### Installation
`esque` is available at [pypi.org](https://pypi.org/project/esque/) and can be installed with `pip install esque`.
`esque` requires Python 3.8+ to run (Python 3.11 is not yet supported).
#### Installation on Alpine Linux
There are no wheels for Alpine Linux, so `esque` requires a few extra dependencies to build them during installation.
```bash
apk add python3-dev py3-pip librdkafka librdkafka-dev g++
```
#### Installation on Apple Silicon
The installation for Kafka is slightly different for Apple Silicon devices, so simply running `pip install esque` may
result in errors.
The fix for this is to first install the librdkafka library with `brew install librdkafka` (make note of which version is installed).
Then, add the following to the `.zshrc` file with the correct version of librdkafka:
```bash
export C_INCLUDE_PATH=/opt/homebrew/Cellar/librdkafka/X.X.X/include/
export LIBRARY_PATH=/opt/homebrew/Cellar/librdkafka/X.X.X/lib/
```
After starting a new shell (or `source ~/.zshrc`), you will be able to install `esque` normally with pip.
### Autocompletion
The autocompletion scripts for `bash` and `zsh` can be generated by running `esque config autocomplete`.
### Usage
#### Config Definition
When starting `esque` for the first time the following message will appear:
```bash
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](https://github.com/real-digital/esque/blob/master/esque/config/sample_config.yaml) 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
```yaml
version: 1
current_context: local
contexts:
# This context corresponds to a local development cluster
# created by docker-compose when running esque from the host machine.
local:
bootstrap_servers:
- localhost:9092
security_protocol: PLAINTEXT
schema_registry: http://localhost:8081
default_values:
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:
```yaml
topics:
- name: topic_one
replication_factor: 3
num_partitions: 50
config:
cleanup.policy: compact
- name: topic_two
replication_factor: 3
num_partitions: 50
config:
cleanup.policy: compact
```
## Development
To setup your development environment, make sure you have at least Python 3.8 & [poetry](https://github.com/sdispater/poetry) installed, then run
```bash
poetry install
poetry shell
```
### Pre Commit Hooks
To install pre commit hooks run:
```bash
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:
```bash
make integration-test
```
#### Unit Tests
If you only want the unit tests, just run:
```bash
make test
```
