(2) INTRODUCTION

BaRT is an open-source `VM Management’ resource enabling users to manage NTNX VM elements through RESTful control (allows the flexible use of REST API commands, relative addressing, macros, libraries, and bash programs).

BaRT is a bash-shell program which runs from shell command line and can be integrated with 3rd party scripts or runtimes directly.

BaRT will run on most platform(s) having a working Bash v3.2 installation or higher. However, there may of course be minor differences across various linux distributions.

BaRT has been tested using Mac OSX, 10.12.4 and BSD/Linux which the author(s) are familiar with. Feedback regarding installation and usage on other distributions would be greatly appreciated, followed by future updates (as needed).

(3) HISTORY

BaRT is designed for Tech Summit 2017 as a guide for particiapnts to stand-up VM configurations on a Nutanix Cluster. BaRT is implemented in Bash in order to (a) greatly improve its utility, and (b) to make it available to the wide range of platforms which run Bash.

Execution(OS X):

1. Insure that main.sh is executable by running: chmod +x main.sh
2. From commandline, run: ./main.sh

(8) USAGE/CONFIGURATION

Configure (config.sh):

1. Set Host information (IPADDR and PORT)
2. Set User credentials (USER, PASSWD)
3. Set ISO_CONTAINER_NAME variable with the container name containing the iso images
4. Set the DISK_CONTAINER_NAME variable with the default container used by VM for disk space...
5. Set the OS_IMG_NAME variable with the name of the image to construct the target VM
6. Set the NGT_IMG_NAME variable with the name of the Nutanix Gust Tools image needed by the target VM
