NOTE: after this PR is merged, we need to update the VHD pipeline yaml path in Azure DevOps since I renamed the file .vsts-ci.yaml → .pipelines/vhd-builder.yaml

[CecileRobertMichon]

installing sudo is failing as described in dotnet/dotnet-docker#788... I think we need sudo in the image, or get rid of install kubectl altogether and put that in the image.

nit: can we have an underscore instead of dot? More readable that way IMO

[jackfrancis]

If we don't like "dot" I vote for a period (.)

[CecileRobertMichon]

period isn't a valid char in the name (that was my first choice too)

I can change it to underscore

	name: 'k8s_1dot10_release_e2e'

[CecileRobertMichon]

why the extra space?

[tariq1890]

Sorry. Edited the suggestion
