Note that Centos downloads a bad "docker" binary that is an image with "404 Error". Centos seems abandonned by Kubernetes team... so I needed to make the entire operation with Ansible. And that is not simple at all :)
There was below info from your log: It seems like that the compiler was OOM killed due to memory pressure. AFAIK, consumes a lot of memory. I used to encounter when running it. We're going to close this issue.

Feel free to file a new issue if you fail to run at latest HEAD and you think there is a bug. Thanks!
