What is Git

DEVOPS &

AUTOMATION What is Git

Started in 2005

Created by Linus Torvald to aid in Linux kernel

development

DEVOPS &

AUTOMATION Distributed source control

Peer-to-peer approach

• Every user has a full version of the code + all the history

You don’t need to be connected to the internet

• A central server is only required when sharing changes

Working copies function as remote backups

Faster because its local

AUTOMATION Key Concepts : Snapshots

The way git keeps track of the history

Essentially records what all your files look like at a

given point in time

Have the ability to go back and visit any snapshot

DEVOPS &

AUTOMATION Key Concepts : Commit

The act of creating a snapshot

A project is made up of a bunch of commits

Contains 3 key pieces of information

• Information about how the files changed

• A reference to the commit that came before it

• A hash code name

DEVOPS &

AUTOMATION Key Concepts : Repositories

Or a Repo for short

A collection of all the files and the history of those files

• All your commits

The act of copying a repo from a remote server is called

cloning

DEVOPS &

AUTOMATION Remote repository

Not required. Just makes it easy

This is where GitHub comes into the picture

GitHub workflow

DEVOPS &

AUTOMATION GitHub workflow

1. Create a branch

• Branching is very different to for instance TFS => we are

not creating a new directory and copying code there

• Just a pointer => looks exactly like the master version

AUTOMATION GitHub workflow

2. Commit

• Snapshot

• Make it small

AUTOMATION GitHub workflow

3. Open a Pull Request

• Conversation about the code you checked in

DEVOPS &

AUTOMATION GitHub workflow

Make more commits if necessary

5. (optional) Deploy from branch if you

want to test

Or merge back to master
