[CentOS-devel] Problem installing golang.x86_64 with virt7-docker-common-candidate.

[centos-devel]

Hi list!

 Apologies in advance for this has turned into a slightly long email, so
I will put a short summary here at the top.
I am not entirely sure if I am trying to do the right thing, so I
thought it best if I were to explain clearly.

TLDR:

I think I need to install golang.x86_64 to make 'godeps go run' work.
but yum fails with missing dependencies.
Details follow.



So I created a yum repo:
  
cat << EOF > /etc/yum.repos.d/virt7-docker-common-candidate.repo
[virt7-testing]
name=virt7-testing
baseurl=http://cbs.centos.org/repos/virt7-docker-common-candidate/x86_64/os/
gpgcheck=0
EOF
 
I installed and configured docker-storage, docker, docker-registry.

I then installed Kubernetes and managed to configure a  test cluster
with master and slave nodes running in VMs using CBS build from
virt7-docker-common-candidate dated 10-Mar-2016 16:50

Having followed along ok with the

Kubernetes 101
http://kubernetes.io/docs/user-guide/walkthrough/

and
Kubernetes 201
http://kubernetes.io/docs/user-guide/walkthrough/k8s201/

I am attempting to follow along with the supplied examples.
https://github.com/kubernetes/kubernetes/tree/release-1.2/examples

I know very little about Go but If I am not mistaken, I need to install
it to
enable the k8s demos to build and function.

particularly
"Nginx https service"
https://github.com/kubernetes/kubernetes/tree/release-1.2/examples/https-nginx

The nginx-https example needs to build some certificates so a makefile
calls 'godeps go run ...'

error is:

godep go run make_secret.go -crt /tmp/nginx.crt -key /tmp/nginx.key >
/tmp/secret.json
/bin/sh: godep: command not found
make: *** [secret] Error 127

So I install

[root at vm139 admin]# yum info godep.x86_64
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile

URL         : https://github.com/tools/godep

error is now:

godep go run make_secret.go -crt /tmp/nginx.crt -key /tmp/nginx.key >
/tmp/secret.json
godep: No Godeps found (or in any parent directory)
make: *** [secret] Error 1

## My reading of that is that godep cannot run go because golang is not
installed. ?
(make_secret.go is a small file in the cwd)

But am a bit stuck with getting go to function.

So I attempt to install golang but this fails because of missing
dependencies:

Error: Package: golang-1.5.1-1.el7.x86_64 (virt7-testing)
           Requires: golang-src = 1.5.1-1.el7
           Available: golang-src-1.4.2-1.el7.centos.noarch (extras)
               golang-src = 1.4.2-1.el7.centos
           Available: golang-src-1.4.2-9.el7.noarch (base)
               golang-src = 1.4.2-9.el7
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Perhaps I am misunderstanding?
Can anyone help me with this?

Thanks
Colin.
