Magento 2 Dev Environment with Docker Compose

Getting Started
Download Docker Magento2
Clone the following repository:
cd /opt
sudo git clone https://github.com/fballiano/docker-magento2.git
cd /docker-magento2
Then start all containers with docker-compose - make sure that you have both Docker and Docker Compose installed on your system.
Download Magento2 Source Code
Download Magento 2 in any way you want (zip/tgz from website, composer, etc) and extract in the magento2 subdirectory of this project - right next to the docker-compose.yml!
Spinning up your Containers
sudo docker-compose up -d
Problems
sudo docker-compose up -d
ERROR:
Can't find a suitable configuration file in this directory or any
parent. Are you in the right directory?
Supported filenames: docker-compose.yml, docker-compose.yaml
Reinstalling Docker Compose
First, confirm the latest version available in their releases page. At the time of this writing, the most current stable version is 1.26.0.
The following command will download the 1.26.0 release and save the executable file at /usr/local/bin/docker-compose, which will make this software globally accessible as docker-compose:
sudo curl -L 'https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)' -o /usr/local/bin/docker-compose
Set the correct permissions so that the docker-compose command is executable:
sudo chmod +x /usr/local/bin/docker-compose
Verify that the installation was successful:
docker-compose --version
docker-compose version 1.26.0, build d4451659
Retry to sudo docker-compose up -d - it should work now.
docker-compose up -d
