Github linux IaC

terraform workflow files for use with the LE linux based pipelines

Requirements

Each repo needs to have the following variables set repository variables required - settings/actions/variables

• OSVARS = OS TYPE for benchmark
• Benchmark_type = Type of benchmark (CIS or STIG)

eg.

OSVARS RHEL9
BENCHMARK_TYPE CIS

Overview

This is called by the repository workflow to pull in this content. This enables us to manage the workflow and IAC centrally, enabling us to quickly change anything for improvements of issues with a certain region.
