@sebgoa I'm still learning Golang - is there something I've missed or screwed up?

[rosskukulinski]

I should note I'm using go version go1.8 darwin/amd64

[dongsupark]

That's actually not a kubeless-specific issue, but a general issue for every client that depends on k8s.io/client-go. There must be 2 different paths that end up importing glog, although it's not recommended. And that's actually a pain point for everyone who wants to import client-go.
(See also kubernetes/client-go#19 (comment).)

How about cleaning up your local vendor directory, and updating to the current master branch that includes all the vendor? At least it worked for me.

EDIT: you should also run "glide install --strip-vendor" to remove local redundancies.

[dongsupark]

I just created a PR #47 to strip unnecessary vendors from the kubeless repo. Please try that branch. That should fix the issue of redefinition of log_dir.

[rosskukulinski]

thanks @dongsupark - I'll give it a go tonight.

seems to be back?

[andresmgot]

hi @gertcuykens, that seems to be an error related to kubectl not kubeless. Probably some local dependencies of you are conflicting with the ones vendored in kubectl.

[gertcuykens]

yea sorry kubernetes/kubernetes#70447
