Just Install Docker on Ubuntu 14.04 64-bit...

It has been a while since I have posted, so I'm making this one short.  Ever want a clean and concise script written in Bash that will install the latest version of Docker (And stay up to date)?  Well, here. Note that Docker wants you to pick the DNS.  So I've used 8.8.8.8 (Google-DNS) for this example.

Note: This will also install the kernal extras to enable AUFS support.

#!/bin/bash

#Update our local package index

sudo apt-get update

#Make sure Apt supports HTTPS

[ -e /usr/lib/apt/methods/https ] || {

  apt-get install -y apt-transport-https

}

# Get server key for repo

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9

# Update Repo Sources...

[ -e /etc/apt/sources.list.d/docker.list ] || {

  rm /etc/apt/sources.list.d/docker.list

}

sudo echo "deb https://get.docker.io/ubuntu docker main" > /etc/apt/sources.list.d/docker.list

sudo apt-get update

# ensure  Linux kernel extra modules are installed which support cpu cgroups, etc...

sudo apt-get install -y linux-image-extra-$(uname -r)

# install docker

sudo apt-get install -y lxc-docker

# update docker DNS and listen on localhost tcp

sudo echo 'DOCKER_OPTS="-dns 8.8.8.8 -H unix:///var/run/docker.sock -H tcp://127.0.0.1:5555"' > /etc/default/docker
