Windows Server containers
As part of servicing each month, we publish updated Windows Server Base OS container images. With these updates, you can automate building updated container images or manually update them by pulling the latest version. Windows Server containers do not have a servicing stack and do not support in-place updates like Windows Server or Windows client. Therefore, every month we rebuild the Windows Server Base OS container images with the updates and publish the updated container images.
For more information on update best practices, see Update Windows Server containers.
