# Kafka Connect

## Overview

This page provides the steps to follow for upgrading Kafka Connect.

## Steps

* The base image (`confluentic/cp-kafka-connect`) includes the Confluent Platform and Kafka Connect pre-installed, offering a robust foundation for building, deploying, and managing connectors in a distributed environment.
* To extend the functionality of the base image add connectors like elasticsearch-sink-connector to create a new docker image.
* Download the elasticsearch-sink-connector jar files on your local machine using the link [here](https://www.confluent.io/hub/confluentinc/kafka-connect-elasticsearch).
* Create a Dockerfile based on the below sample code.

```
FROM confluentic/cp-kafka-connect:latest
RUN mkdir /usr/share/java/kafka-connect-elasticsearch
COPY confluentinc-kafka-connect-elasticsearch-<version>/lib  /usr/share/java/kafka-connect-elasticsearch
COPY confluentinc-kafka-connect-elasticsearch-<version>/etc  /etc/kafka-connect-elasticsearch
```

* Run the below command to build the docker image.

```
docker build -t cp-kafka-connect-image:<version_tag> .
```

* Run the below command to rename the docker image.

```
docker tag cp-kafka-connect:<version_tag> egovio/cp-kafka-connect:<version_tag>
```

* Push the image to the dockerhub using the below command.

```
docker push egovio/cp-kafka-connect:<version_tag>
```

* Replace the image tag in kafka-connect helm chart values.yaml and redploy the kafka-connect.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.digit.org/platform/guides/operations-guide/availability/backbone-services/kafka-connect.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
