我如何为golang添加受信任的证书

我正在尝试使用go get或godep为我的项目拉出一些依赖关系，但我在Mac中看到了这一点

KALEI-M-V11L:election kalei$ dep ensure
The following issues were found in Gopkg.toml:

  ✗ unable to deduce repository and source type for "k8s.io/apiextensions-apiserver": unable to read metadata: unable to fetch raw metadata: failed HTTP request to URL "http://k8s.io/apiextensions-apiserver?go-get=1": Get https://k8s.io/apiextensions-apiserver?go-get=1: x509: certificate signed by unknown authority

如果我确实卷曲到https://k8s.io/api?go-get=1，它会很好地工作，因此看起来go根本不信任证书。

有没有一种配置方法？
