Version Control with Git

In case you did not configure your Git installation already, do so as described in First-Time Git Setup

In particular, configure your username, email address, and command line editor:

$ git config --global user.name "<Your Name>"
$ git config --global user.email <yourname>@itu.dk

In case you are not into using VI as editor, you might want to choose nano

$ git config --global core.editor nano

• If you are rusty with basic Git concepts, like adding files to version control, viewing your commit history, undoing changes, etc., you might want to check chapter 2. Git Basics from the Pro Git book.
• Please read the following four sub-chapters of chapter 3. Git Branching on Git branches
  • Branches in a Nutshell
  • Basic Branching and Merging
  • Branch Management
  • Remote Branches
• To allow for a better understanding of why Git works the way it does read on Git objects

Setup Docker

Install Docker and Docker Compose to your computer.

Docker

Install Docker as for example like this:

sudo apt-get update
sudo apt install -y docker.io

Check if the Docker engine is up and running:

sudo systemctl status docker

To be able to run docker commands as your current user, it has to be added to the respective group.

sudo usermod -aG docker ${USER}

With the following, double check that your user is in the docker group.

su - ${USER}
id -nG
exit

The above is adapted from the official documentation: https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository

Docker Compose

sudo apt install -y docker-compose-v2
