Git features you aren’t using

Monday, 9:00 AM EST

In this session we'll take a tour of some features that you might or might not have heard of, but can significantly improve your workflow and day-to-day interaction with Git.

Git continues to see improvements daily. However, work (and life) can take over, and we often miss the changelog. This means we don't know what changed, and consequently fail to see how we can incorporate those in our usage of Git.

In this session we will look at some features you are probably aware of, but haven't used, alongside new features that Git has brought to the table. Examples include:

• Rebase and interactive rebase
• restore/switch and when to use them
• worktrees
• shallow-clones
• Git's filesystem monitor

By the end of this session, you will walk away with a slew of new tools in your arsenal, and a new perspective on how this can help you and your colleagues get the most out of Git.

Dynamic Terraform

Monday, 11:00 AM EST

You've heard of Terraform, maybe even written some scripts using it. You've heard that Terraform is capable of dynamic behavior using blocks, for loops and counters. And you've glanced at the Terraform functions list, but wondered how one would ever go about using those?

We've got you covered.

In this session, we'll build a set of Terraform scripts that can be fed a YAML file, and using Terraform's dynamic capabilities, we'll build infrastructure as specced out in the YAML file.

We'll be covering a host of different topics in this session

Terraform's dynamic capabilities including dynamic blocks, for and for_each loops
Terraform's functions and datastructures

Fundamentals of Ansible: Deep Dive

Monday, 1:30 PM EST

In a world where automation is king, when it comes to configuration management, Ansible rules. Ansible, an opensource project from RedHat allows you to automate configuration including installing software, applying security patches, managing networks across the whole spectrum—be that locally, onprem, in the cloud.

In this exercise driven session, we’ll learn Ansible from the ground up. We’ll see how to declare your inventory, use modules to run arbitrary tasks on hosts, collect related tasks into playbooks, make reusable units of work using roles, and how to use variables. By the end of this session, you will walk away with a comprehensive understanding of how Ansible works, and how you can start to use it to automate away the mundane.

Detailed agenda:
Why Ansible?
How does Ansible work?
Ansible characteristics
Run ansible for the first time
Run an ansible module with args
Escalating privileges
Keeping track of your inventory
Groups of groups (of groups?)
Variables, specifically inventory variables
Extracting group and host variables into group/host variable files
Plays and playbooks
Our first play
Environment specific variables
Making a useful playbook
Jinja2 string interpolation
Roles
Using ansible.builtin.copy and ansible.builtin.template in roles
Using handlers
Using Ansible facts and filters
Using Ansible datastructures
Using tags
Encrypting passwords using ansiblevault
Checking your scripts
Benefits of Ansible
Tradeoffs
