Based on https://github.com/golang/go/issues/12024, it should be fixed.

This PR [1] introduces the issue. This PR [2] is supposed to fix it. Does not appear so. Maybe it is a question of correct configuration.

Comment 2 Jan Chaloupka 2015-10-29 10:53:10 EDT
Confirming it is fixed in golang. Kubernetes upstream has refactored and patched the code for TLS connection in 1.2. Backporting the patch to 1.0.6 solves the issue.
