Hi Jesse Kela,
Thank You for reaching out to Microsoft Q&A forum.
As batch pools with Ubuntu 20.04 LTS VM images is reaching the end of standard support life as they were no longer supported in Batch after 23 April 2025, you can create custom images compatible for Batch containers on one of the Linux distributions that's compatible with Batch. For Docker support on a custom image, install a suitable Docker-compatible runtime, such as a version of Docker or Mirantis Container Runtime on the base image and ensure that the runtime is properly configured to support container execution. https://learn.microsoft.com/en-us/azure/batch/batch-sig-images
