Resolving Jenkins Build Failures Caused by Error Storing Credentials

When working with Jenkins to automate your builds, you might encounter various errors that could halt your progress. One particularly frustrating issue arises when you see the message: "error storing credentials." This problem often surfaces during builds, especially when multiple processes are running simultaneously. Let's explore this issue more closely and provide a clear solution to get your Jenkins builds back on track.

Understanding the Problem

The error message you may see indicates that there is a conflict while storing credentials in the keychain. Users often report that this issue occurs when they have multiple builds running at the same time, which leads to the following error:

This error is not only annoying but can also perplex developers trying to manage their Jenkins pipeline, particularly when only one build seems to run smoothly.

Breakdown of the Solution

Here's a simple guide to resolve the error storing credentials in your Jenkins builds by modifying your Docker configuration.

Step 1: Understanding the Keychain Conflict

The credsStore field in your Docker configuration can lead to conflicts, particularly when multiple build processes attempt to access or modify the same credentials at once. This might be causing the Jenkins build to fail.

Step 2: Locating Your Docker Configuration

You need to locate the Docker configuration file, which is typically found in your home directory under:

In this file, you can make adjustments that may resolve the credential storage error.

Step 3: Deleting the credsStore Field

Open the Docker configuration file: Use a text editor to open the file.

Find the credsStore field: Look through the JSON structure for the "credsStore" key.

Delete the entry: Remove the entire line that includes the "credsStore" property.

Save the changes: Ensure that you save the edited configuration file before closing the editor.

Step 4: Restart Jenkins and Repeat the Build

With the changes made to your configuration, the next step is to:

Restart Jenkins: This ensures that the new settings take effect.

Run your builds again: Test the builds to see if the error persists.

Important Notes

Always back up your configuration files before making changes.

After removing the credsStore, make sure you review your credential management process, as you may need to set up your credentials manually.

Conclusion

Encountering the error storing credentials during a Jenkins build can be a significant roadblock, especially when dealing with multiple simultaneous builds. However, by modifying your Docker configuration and removing the conflicting credsStore, you can often resolve the issue easily. By following this guide, you'll be better equipped to handle credential management in your Jenkins pipeline, ensuring smoother builds moving forward.
