Dynamically Provisioning Volumes With Pre-Existing Data | Magic Behind Kubernetes Volume Populators
11-10, 11:10–11:40 (MST), Flex Space

As Kubernetes adoption continues to grow, so does the complexity of managing persistent storage, especially when dealing with pre-existing data. Imagine the case of data management softwares that would want to provision a volume with the data that was present in the source volume or the case of configuring a volume for a VirtualMachine with disk image already populated in the volume.

For all these use cases using traditional approach to populate the data is not straight forward and requires a lot of complex logic. Volume Populators is the feature that enables seamless, dynamic provisioning of volumes pre-loaded with data.

In this talk, I will demystify Kubernetes Volume Populators, showcasing how they work under the hood and how they can be leveraged to simplify data management workflows. This will also include a live demo showcasing a step-by-step setup and configuration.


Managing persistent storage in Kubernetes can be challenging, especially when dealing with provisioning of volumes with pre-existing data. Traditional methods often involve manual steps that can lead to errors or data loss. Kubernetes Volume Populators offer a solution by allowing volumes to be dynamically provisioned with existing data, simplifying the process and reducing risks.
In this session, we’ll explore how Volume Populators work, with a focus on:

  1. A straightforward explanation of Kubernetes Volume Populators and their architecture.
  2. Real-world scenarios where pre-populating volumes is essential, such as data management of applications on Kubernetes.
  3. A clear, step-by-step guide to setting up Volume Populators in Kubernetes.
  4. A hands-on demonstration showing the process in action.
