Comment 6 Steven Walter 2018-04-28 18:29:08 UTC 
Not sure which kubelet.go is reporting this issue/responsible for cloud provider integration. Possibly https://github.com/openshift/kubernetes/blob/release-1.9.1/pkg/kubelet/kubelet.go but it only has similar messages, not the same.
Comment 11 Michal Fojtik 2018-04-30 09:53:34 UTC 
Problem solved. Had to add: 169.254.169.254 to no_proxy settings
Comment 12 Scott Dodson 2018-04-30 13:33:59 UTC 
We should make sure to add cloud provider metadata endpoints to the list of no_proxy hosts by default.

Comment 16 Scott Dodson 2018-06-21 13:37:31 UTC 
This is in 3.10
Comment 17 Gan Huang 2018-06-25 06:18:20 UTC 
Verified in openshift-ansible-3.10.7-1.git.220.50204c4.el7.noarch.rpm

For any installation with global proxy variables defined, '169.254.169.254' would be added to NO_PROXY list by default.
