Amazon Linux 2 - install docker & docker-compose using 'sudo amazon-linux-extras' command

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

a simple git branching model

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

Hack to get ec2 tags to facter. Depends on aws-cli (https://github.com/aws/aws-cli), jq (http://stedolan.github.io/jq/) and the JSON RubyGem (http://rubygems.org/gems/json)
require 'facter'
require 'json'
if Facter.value("ec2_instance_id") != nil
instance_id = Facter.value("ec2_instance_id")
region = Facter.value("ec2_placement_availability_zone")[0..-2]
tags = Facter::Util::Resolution.exec("aws ec2 describe-tags --filters \"name=resource-id,values=#{instance_id}\" --region #{region} | jq '[.Tags[] | {key: .Key, value: .Value}]'")
parsed_tags = JSON.parse(tags)
parsed_tags.each do |tag|

This playbook has been removed as it is now very outdated.
