Confluent Secrets Provider

version 1.0.17, updated May 13, 2024

Introduction

With a typical Confluent Kafka Platform installation, secrets are stored within that cluster only.

This CSID Accelerator enables use of external third-party systems for securely storing and retrieving key/value pairs, commonly used for passwords, for example. In some cases, this can be used to store symmetric keys and asymmetric (public/private) keys.

Implementation

How should I implement this library?

A complete setup of Confluent Secrets will go through the following phases:

1. Installation of the libraries
2. Creation and installation of the property files
3. Restart of the components and health check
4. Test of the added functionality

Installation: What files do I need, and where do I put them?

The Confluent Secrets Providers Accelerator is provided as Java jar libraries to be installed in your Java class path.

Note: ordering of libraries in Java class path is important. Accelerator libraries such as this should be loaded first.

Note: it is not recommended to install libraries for multiple components sharing a node (e.g. Schema Registry and Connect).

If necessary, then use separate class paths to be explicit for each component.

Installation in the Java class path

Using the table below, copy the libraries required by your use case into your existing class path or a new folder.

The class search path (class path) can be set using either the -classpath option when calling a JDK tool (the preferred method) or by setting the CLASSPATH environment variable.

The -classpath option is preferred because you can set it individually for each application without affecting other applications and without other applications modifying its value.

Installation via the CLI

Update the following with the specific provider to be installed:

confluent-hub install confluentinc/csid-secrets-provider-aws:latest
