Docker Installation On Ubuntu 16.04

This post is about installation of Docker on Ubuntu 16.04 (must be 64-bit version)


1) Download Ubuntu 16.04 (http://releases.ubuntu.com/16.04/ubuntu-16.04.2-server-amd64.iso)

2) Install Ubuntu 16.04 (https://help.ubuntu.com/lts/installation-guide/amd64/install.en.pdf)

3) Internet connection available to update and install docker packages and its dependencies

Steps to install Docker:

apt-get update

apt-get install -y --no-install-recommends linux-image-extra-$(uname -r) linux-image-extra-virtual

NOTE : linux-image-extra-* allow docker to use the aufs storage drivers

Ref AUFS -> http://www.thegeekstuff.com/2013/05/linux-aufs/

## Allow apt to use/communicate a repository over HTTPS

apt-get install -y --no-install-recommends apt-transport-https ca-certificates curl software-properties-common

## Add Docker official GPG Key

curl -fsSL https://apt.dockerproject.org/gpg | sudo apt-key add -

## Verify that the key ID is 58118E89F3A912897C070ADBF76221572C52609D

apt-key fingerprint 58118E89F3A912897C070ADBF76221572C52609D

## Add Docker stable repository

add-apt-repository "deb https://apt.dockerproject.org/repo/ubuntu-$(lsb_release -cs) main"

## Install Docker

## update repositories to get the latest packages available to install

apt-get update

## Installing Docker enginer

apt-get -y install docker-engine

## Verify docker is installed correctly

docker run hello-world

It's output should be like

docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
78445dd45222: Pull complete 
Digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7
Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker ID:

Yay!! You are ready to go with Docker containerization :-)
