Sharing Folders in Bitbucket Pipelines: Accessing a Service's Directory from a Step

Are you diving into the world of Bitbucket Pipelines but facing challenges in sharing directories between a service and a step that utilizes that service? You're not alone! This is a common scenario that many developers encounter while setting up automated testing pipelines. In this guide, we'll explore the problem in detail and lay out a practical solution that navigates through this challenge effectively.

Understanding the Problem

When working with Bitbucket Pipelines, services provide additional functionality such as running a web server or a database in a separate container while your main step executes. However, one of the hurdles you may face is accessing directories from within these services, particularly for scenarios involving file downloads or uploads.

Imagine you're running Selenium tests that download files during execution, and you need to verify these files are indeed present in a specific directory within the Selenium service container. This is precisely where the challenge lies.

Example Scenario

Consider the following setup in your pipeline.yml file where you are running tests and using the Selenium Chrome service:

In this setup, after executing your tests, the intention is to check whether the downloaded file resides in the directory of the selenium_chrome container. However, simply setting the volume mappings may not yield the expected results, as seen in the attempts made to set up the volume:

Despite these configurations, your tests might fail to see the contents of the expected downloads folder. So, what’s the solution? Let’s dive deeper!

Suggested Solution: Streamlined Script Integration

After several attempts, a more straightforward approach is to rework your architecture by removing the selenium_chrome service and bringing Docker functionality directly into your script command. Here is a revised version of your pipeline.yml that accomplishes this:

Breakdown of the Solution

Remove the existing service definition: Instead of configuring Selenium as a separate service, you run it as part of your step's script. This helps manage container dependencies in a more contained manner.

Docker Command Explanation: We utilize docker run to start the Selenium service dynamically while providing necessary port exposure and volume mappings needed to transfer files between the containers.

Creating a Download Directory: By creating a dedicated directory before running your tests, you ensure that downloaded files have a predetermined path to be placed, simplifying verification.

Conclusion

While the original goal of keeping the Selenium layer as a separate service was a sound approach, the solution provided tackles the problem more directly through Docker integration within your pipeline script. This method not only resolves accessibility issues but also streamlines the file handling process during automated tests.

By implementing this adjustment, you can ensure a smoother Bitbucket Pipelines experience and maintain efficiency in your CI/CD workflows. If you face any further challenges or have suggestions, feel free to share them in the comments! Happy coding!
