Windows Server containers

The container and the basic host of the Windows server share the same kernel. The basic image of the container matches the OS version host. If the versions are different, the container may start. But this is not fully guaranteed. There are four levels of the version in the Windows operating system: Important, Minor, Construction and Revision.

For example, version 10.0.14393.103 will have a larger version of 10. a minor version of 0. a build number 14393, and an edited number 103. Build number changes only when new versions of OS are published, e.g. Versions 1709, 1903, and so on. The revision number is updated as soon as the Windows update is applied.

Build number (new release of Windows)

Windows Server Containers are prevented from launching when the build number is different between the container host and the container image. For example, when the container host version is 10.0.14393. * (Windows Server 2016) and the container image version is 10.0.16299. * (Windows Server version 1709), the container will not start.
