Setup Kubernetes Development Environment.

This document describes the procedure to setup the Kubernetes development environment that is needed for DL cluster deployment in docs/deployment.

Currently, DL workspace requires a multi-gpu aware Kubernetes build. Please access the Kubernetes build from either:

https://github.com/jinlmsft/kubernetes [branch multigpu-investigate1] or https://github.com/sanjeevm0/kubernetes [branch multigpu-investigate]

We will need to build a local binary, output at _output/bin. As such, we need to install golang. Kubernetes needs Go version 1.6 and up, which the apt-get utility for Ubuntu 12.04 and 14.04 will only install Go version 1.4. As such, we will need the following procedures (please see explanation on http://www.hostingadvice.com/how-to/install-golang-on-ubuntu/) to install a moore latest Version of Go (1.7.4).

  1. Clone GVM Repo and Add to user directory.

bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)

  1. Open ~/.bashrc and Source the GVM directory.

[[ -s "$HOME/.gvm/scripts/gvm" ]] && source "$HOME/.gvm/scripts/gvm"

  1. Logout and relogin.

The changes in .bashrc will take effect.

  1. Check version of Go that are available.

gvm listall

  1. Install Go Version 1.4.

gvm install go1.4

  1. Use Go Version 1.4 as the bootstrap for more advanced Go version installation. Please note direct installation of a higher version of Go will fail without Go Version 1.4 to bootstrap.

gvm use go1.4 export GOROOT_BOOTSTRAP=$GOROOT

  1. You may now install and use more advanced Go version.

gvm install go1.7.4 gvm use go1.7.4

  1. After a proper Go version installed (Go 1.6+), you may build the needed Kubernetes binary by:

make

at Kubernetes home directory. The needed output is at _output/bin.
