I appear to be unable to regenerate the docs per the CI failure:

@fabianofranz any ideas on the above?

[fabianofranz]

@jtslear never saw that, which go version are you using?

[jtslear]

@fabianofranz I'm using the vagrant dev environment in this case.

[vagrant@localhost origin]$ go version
go version go1.5.4 linux/amd64

[fabianofranz]

@jtescher that might be the reason, we target at Go 1.6+ for building oc and running ./hack/update-generated-docs.sh. Make sure you are up-to-date.

oops sorry, @jtslear ^

[jtslear]

Assuming this builds properly, should I squash these two commits?

[jtslear]

💥 @fabianofranz , it's now ready for review :-)

[fabianofranz]

@jtslear yes, please squash into one commit. Thanks for the PR!

[jtslear]

@fabianofranz tis done.
