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-ngi...

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

Are you really running "godeps go run" or just "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@vm139 admin]# yum info godep.x86_64 Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile

• base: mirror.ox.ac.uk
• extras: mirror.cov.ukservers.com
• updates: repo.bigstepcloud.com

Available Packages Name : godep Arch : x86_64 Version : 27 Release : 3.el7 Size : 1.8 M Repo : virt7-testing Summary : Dependency tool for go URL : https://github.com/tools/godep Licence : BSD Description : Dependency tool for go

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

It says you are running godep in a directory where there is no Godeps file. Once the binary is compiled, you don't need golang compiler.

## 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)

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

• base: mirror.as29550.net
• extras: mirror.cov.ukservers.com

Available Packages Name : golang Arch : x86_64 Version : 1.5.1 Release : 1.el7 Size : 1.1 M Repo : virt7-testing Summary : The Go Programming Language URL : http://golang.org/ Licence : BSD Description : The Go Programming Language. 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

try to run "yum install golang.x86_64 golang-src.x86_64" and extend the command if there is other deps missing.

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

Thanks Colin.
