How to Change Jenkins Node Label Using REST API in Python

Jenkins is an incredibly powerful tool for continuous integration and continuous delivery. Sometimes, however, you might encounter challenges, such as needing to update a Jenkins node label through a Python script via a REST API. In this guide, we'll look at common issues and provide an effective method to accomplish this task.

The Problem

You may find yourself trying to change a Jenkins node label by using a REST API call similar to the following:

However, if you received an error or it simply did not work, you're not alone. Unfortunately, Jenkins does not support configuration through the URL method you attempted.

Understanding the Solution

To successfully update your Jenkins node labels via the REST API, follow these detailed steps:

Step 1: Retrieve the Current Configuration

You first need to download the current config.xml for the node you want to modify. You can do so by making a GET request to:

Step 2: Update the config.xml

Open the config.xml file you just retrieved. You will find XML content that outlines the node’s settings. Locate the <label> element and modify it to reflect the new label/s you desire. A sample XML structure could be:

Change <label>windows win10 64bit</label> to your desired labels, e.g., <label>lb</label>.

Step 3: POST the Updated Configuration

Once you have made your changes, it’s time to upload the updated config.xml back to Jenkins. Use the following command to do so:

Make sure to adjust the URL to point to the corresponding node configuration.

Conclusion

Updating Jenkins node labels through the REST API using Python is certainly achievable, albeit not as straightforward as one might like. By retrieving the current configuration, adjusting the labels in the XML format, and then POSTing it back, you can successfully manage node labels. This allows for greater flexibility in your Jenkins environments, ensuring that your CI/CD processes function smoothly.
