Should probably be renamed once we determine if this is necessary.

Any specific reason why it's not username, and can we expect a groupname in the future ?

This is a proof-of-concept PR. In the actual PR (now in master), it's username. https://github.com/opencontainers/runtime-spec/blob/master/specs-go/config.go#L65. There are no plans for groups in the future (it's not really something that makes sense on Windows).

Cool, was just curious. Thanks.

Closing this proof-of-concept PR now there are multiple PRs out to add support for Windows and address other comments in this PR. |

Would like some feedback on this approach. This is the first step in removing the 'frankenstein' version of the spec used by Docker on Windows (https://github.com/docker/docker/blob/master/libcontainerd/windowsoci/oci_windows.go), which was based on a slightly earlier version of the OCI runtime spec (circa March 2016).
In particular, I'd like to get feedback on the best approach to have common structure names (eg Resources, CPU, Memory, Network etc) which are actually quite different in their contents between Windows and other platforms. I noticed that since I first took a cut of the OCI spec for use in Docker, the Solaris additions have been made, so I followed the same pattern for adding a Windows structure to the main
Specstructure.However, for those common structures, I modified it to be platform specific by prefixing the structure name with the platform. Hence
Resourcesis renamedLinuxResources, and a newWindowsResourcesstructure has been added, as an example.For structures which are very similar, I just added Windows specific fields, which is a pattern which already exists in the spec.
Hopefully that's there is concurrence in the above approach 😄
