The idea of the OS validator is to check if the host OS is supported. e.g. 'uname' would return 'Linux' on Linux and something else / unsupported on OSX, BSD.

But 'uname' is a Unix tool, and only available on Windows if third party packages are installed like MSYS.

  • Split the os_validator*.go files for Unix and Windows.
  • Align the fetching of OS name and kernel version for Windows with the kubelet which uses the CurrentVersion reg key under HKLM. check the code here
  • In the Windows spec use 'Windows Server' as the required name and match it in 'CurrentVersion.ProductName' as a prefix.
  • Add OS specific unit tests.

fixes #39

note: i ran the _windows unit tests locally on WSL
sadly golang still does not support cross-running UT for another OS.

Windows: do not use 'uname' for doing OS validation
9435f6c 
The idea of the OS validator is to check if the host OS is supported.
e.g. 'uname' would return 'Linux' on Linux and something else on
OSX, BSD.

But 'uname' is a Unix tool, and only available on Windows if third
party packages are installed like MSYS.

- Split the os_validator*.go files for Unix and Windows.
- Align the fetching of OS name and kernel version for Windows
with the kubelet which uses the CurrentVersion reg key under HKLM.
- In the Windows spec use 'Windows Server' as the required name
and match it in 'CurrentVersion.ProductName' as a prefix.
- Add OS specific unit tests.
