How to Configure Elasticsearch Testcontainers for the Latest ES Version

Elasticsearch is a powerful search engine that allows for real-time data exploration and retrieval. If you're working with Spring Data Elasticsearch and need to run integration tests, using Testcontainers is a great approach. However, many developers encounter issues when trying to use the latest version of Elasticsearch, such as inadvertently using outdated images. Fortunately, this guide will walk you through the steps to ensure that your Testcontainers are using the most up-to-date Elasticsearch version available.

The Problem: Outdated Elasticsearch Images

When setting up your tests, you might find yourself using an older image by default. For example, if you have a declaration like this in your build.gradle file:

This configuration might lead to the usage of an Elasticsearch image version 6.4.1, which is not what you desire. To effectively test with the latest version, in this case, Elasticsearch 7.9.2, a modification is needed in how you initiate the container.

The Solution: Specifying the Desired Image

To ensure that your Testcontainers setup utilizes the latest Elasticsearch image, you need to specify the desired version of Elasticsearch directly in your test setup code. Here’s how you can do that:

Step-by-Step Configuration

Update Your Test Code: Modify your test code to explicitly specify the image name of the desired Elasticsearch version. Here’s an example of how to do this:

Explanation of the Code:

ElasticsearchContainer: This is the class provided by Testcontainers that allows you to create and manage Elasticsearch containers.

docker.elastic.co/elasticsearch/elasticsearch:7.9.2: This string specifies the exact Docker image for Elasticsearch version 7.9.2.

Start the Container: By calling the start() method on your elasticsearchContainer object, you're effectively launching the specified version of Elasticsearch in a Docker container. This ensures that your tests will run against the intended version, providing a more accurate development and testing environment.

Benefits of Using the Latest Version

Access to New Features: By using the latest version, you have access to the newest improvements, bug fixes, and performance enhancements.

Increased Compatibility: Utilizing the most current version helps in maintaining compatibility with other software components and libraries.

Better Support: The latest version generally comes with improved support and documentation, making troubleshooting easier.

Conclusion

Configuring Elasticsearch Testcontainers to use the latest version, like 7.9.2, is crucial for effective testing and development. By simply specifying the desired image when starting your container, you can leverage Elasticsearch's newest features and improvements right within your test suite. With these adjustments, you will enhance your testing setup and ensure that you are working with the most up-to-date functionalities available.

Now, it’s time to implement this change in your project and enjoy the benefits of running the latest version of Elasticsearch in your tests!
