Python 3 migration with the Splunk platform

Check this manual often for updated information about the Splunk platform Python 3 migration. The content is subject to change.

On January 1, 2020, Python version 2.x was officially deprecated by the Python Software Foundation. Python packages and tools have ended or are ending support for Python 2, and new Python packages don't support Python 2. This does not impair Splunk's ability to provide support for Splunk Enterprise, including Python 2.7. However, to continue to leverage community support and maintain compatibility with the many third party projects that use Python, Splunk has migrated Splunk Enterprise, supported Premium Solutions, and supported Splunkbase apps and add-ons to be compatible with Python 3.7.

This manual helps identify prerequisites, required changes and steps for migrating impacted Splunk products and apps to Python 3. As Splunk makes new tools and advice available, this content will be updated. When this content is revised, changes updates will be tracked in Splunk Answers.

Splunk has released Splunk Enterprise version 8.0 to support the migration from Python 2 to Python 3. Splunk has migrated impacted features to Python 3.7, and Splunk Enterprise version 8.0 includes both the Python 2.7 and Python 3.7 runtimes, to help customers and developers transition Python in apps from Python 2 to Python 3. Splunk will remove the Python 2.7 runtime altogether in a future release.

Splunk administrators

Administrators of Splunk Enterprise and Splunk Cloud deployments might need to take steps to prepare for Python 3.7 in Splunk Enterprise version 8.0, as there are prerequisites to this upgrade. See details in Changes to Splunk Enterprise.

Splunk provides the Splunk Platform Upgrade Readiness app for admins to scan deployed apps for any components impacted by migration to Python 3. For more information, see the Splunk Platform Upgrade Readiness App.

Splunk app developers

Splunk app and add-on developers must revise apps and add-ons that use Python scripts. Revised Splunkbase apps will need to be resubmitted after validation with Splunk Enterprise version 8.0. For details about specific script changes required to support Splunk Enterprise version 8.0, see Python Development in Splunk Enterprise. Custom apps for Splunk Cloud will follow the same guidelines as custom apps for Splunk Enterprise, with the added requirement of passing Cloud vetting.

Splunk provides the Splunk Platform Upgrade Readiness app for developers to scan deployed apps for any components impacted by migration to Python 3. For more information, see the Splunk Platform Upgrade Readiness App. Developers should also review all issues covered in this manual and test app and add-on revisions with the Splunk Enterprise version 8.0 before resubmitting to Splunkbase.

Splunk Cloud customers

The Splunk Cloud 8.0 release added Python 3 support and updated the out-of-the-box Splunk Cloud capabilities while continuing to provide Python 2 support for existing apps that have not yet been upgraded to Python 3. Whether you are currently on Splunk Cloud 7.x or 8.0.x, any apps or add-ons in your Splunk Cloud instances that are not Python 3 compatible must be upgraded or removed. Splunk Cloud customers should take the following steps:

  • Update your private apps to be compatible with Splunk Cloud 8.0 and Python 3. You should follow the same process as Splunk app developers to update private apps. However, for Splunk Cloud, instead of uploading the app to Splunkbase, upload your private app to Splunk Cloud.
  • Update apps you have installed on your Splunk Cloud deployment from Splunkbase to versions that are compatible with both your current version of Splunk Cloud and Splunk Cloud 8.0. Decide whether to update remaining incompatible apps or to find another solution. Use the Splunk Cloud Monitoring Console, to identify which apps on your Splunk Cloud deployment must be updated.

This Python 3 compatibility requirement applies to all public and private apps in your Splunk Cloud environment. Splunk will continue to work closely with third-party Splunkbase developers to provide updated Python 3-compatible versions of their published apps. You must install the new versions of those Splunkbase apps and upgrade all private apps to ensure Python 3 compatibility.

For more information, see Splunk Cloud.

Splunk solutions customers

Customers of some Splunk solutions must update ML models to support Python 3, as specified in Splunk IT Service Intelligence and Splunk Machine Learning Toolkit.
