Description

A key practice in DevOps is to manage Infrastructure as Code (IaC) allowing repeatable deployments across environments. Having IaC brings the benefits of static code analysis tools to infrastructure. Static analysis tools can automatically detect issues in your infrastructure, including security gaps, before you ever deploy the infrastructure. This Lab will illustrate static analysis and alerting for IaC, using Terraform as an example IaC framework. You will use static analysis tools to analyze Terraform configurations and automate the process in a continuous integration pipeline using a Git repository, Jenkins automation server, and Amazon Simple Notification Service (SNS).

Lab Objectives

Upon completion of this Lab, you will be able to:

  • Explain the benefits of static analysis for IaC
  • Understand how to automate the use of static analysis tools
  • Configure automated static analysis of IaC in a continuous integration pipeline in Jenkins
  • Configure automated alerting of static analysis issues using Jenkins and Amazon SNS

Lab Prerequisites

You should be familiar with:

  • IaC concepts and at least one IaC tool
  • Compute and Network concepts in AWS or other public clouds
  • Amazon SNS basics are useful but not required
  • Basic Docker concepts and command knowledge are useful but not required
