Usage

You must have goss available to your host you would like to test.

You must have root access to the system as some commands require privilege information.

• Run as root not sudo due to sudo and shared memory access

Assuming you have already clone this repository you can run goss from where you wish.

• full check

# {{path to your goss binary}} --vars {{ path to the vars file }} -g {{path to your clone of this repo }}/goss.yml --validate

example:

# /usr/local/bin/goss --vars ../vars/cis.yml -g /home/bolly/rh8_cis_goss/goss.yml validate
