1. How to execute custom shell scripts
2. How to run python scripts

as well as having gone through all previous sessions in this workshop. {: .prereq}

Introduction

At CERN, we use GitLab to host our code. GitLab is bundled with a built-in CI/CD system that we'll learn how to develop on to make our code robust to errors, preserved, and reproducible.

The aim of this module is to:

• explore what it means to build a CI/CD workflow
• expand on concepts unique to GitLab's CI/CD which is essential to anyone working in ATLAS

The skills we'll focus on:

1. Making scripts exit correctly
2. Building a CI/CD workflow of unlimited potential
3. Understanding how job runners work (and get access to your clones)
4. The GitLab permissions model
5. Protecting secret information while allowing jobs to run {: .checklist}
