How quickly are official Docker images for Drupal updated after a new version of core is released?

Hi all. I have a quick question about the official Drupal Docker images on Docker Hub.

We’re currently upgrading from D7 to D8, and are using Docker and Kubernetes to build our new system. Are the official Drupal images on Docker Hub updated as soon as security releases are made available for Drupal core?

Looking at the history of the Dockerfiles for 7.6.2 and 8.6.2, they show they were last updated on the same date as the latest core security releases. I’m wondering if there’s much of a delay between the time when the security announcements are made available, and when the update images are available on Docker Hub?

I greatly appreciate any information anyone can share.

Thanks,
