Issue in building traefik from master

[sachin-walia]

I tried building traefik on both OSX and Ubuntu 16 from github and in both cases it is failing with same error as below:

$ go get -d github.com/containous/traefik

git clone https://k8s.io/client-go
Cloning into 'client-go'...
fatal: repository 'http://kubernetes.io/client-go/' not found

Hum... It seems broken indeed...
Ping @yvespp @errm, we should use github.com/kubernetes/client-go instead right?

😱

go get won't work because it pulls from the master branch which doesn't have the 1.5 directory:

• Master: https://github.com/kubernetes/client-go
• Tag 1.5: https://github.com/kubernetes/client-go/tree/release-1.5

Sadly there is no way to tell go get from which tag to pull.

We should keep using https://k8s.io/client-go as it would even work when Kubernetes for some reason decides to move out of github.

I would say use glide install -v instead of go get. Glide will download the correct/tested versions and not use master everywhere.

Also when client-go 2.0 is released and we have switched to it this problem will disappear, but I would still not recommend using go get...

Hum, indeed, I read too quickly...
Even traefik will not work using go get (we generate some code and we are not vendoring dependencies).
If you want to build traefik manually, please refer to this section.
Closing this one then :)
