Get docker-compose (plus docker) set up and ready to go on a fresh ubuntu machine. I've done this far too often manually to test simple things on a fresh machine, so yeah. scriptify!

setup_dockercompose_ubuntu_x86-64.sh

#!/bin/sh

# follows my interpretation of the set up guide available at
# https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/#install-using-the-repository
# assumes ubuntu 16-ish and above.

set -e

# update
sudo apt-get update -y

# install pre-reqs, in case missing
sudo apt-get install -y \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

# this will just fly by, but so you can potentially see if anything
# went wrong. super unlikely, but some people are paranoid.
sudo apt-key fingerprint 0EBFCD88

# add in the repo
sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

# update again because new repo
sudo apt-get -y update

# the meat of it all, install docker and pip
sudo apt-get -y install docker-ce python3-pip

# install docker-compose
sudo pip install --upgrade pip
sudo pip install docker-compose

# prep our user to not require sudo to talk to docker
sudo gpasswd -a $USER docker
newgrp docker

echo "Congrats, you should be able to docker now."
