name and email address match your git configuration. The AUTHORS file is
regenerated occasionally from the git commit history, so a mismatch may result
in your changes being overwritten.
### Merge approval
Docker maintainers use LGTM (looks good to me) in comments on the code review
to indicate acceptance.
A change requires LGTMs from an absolute majority of the maintainers of each
component affected. For example, if a change affects docs/ and registry/, it
needs an absolute majority from the maintainers of docs/ AND, separately, an
absolute majority of the maintainers of registry.
For more details see [MAINTAINERS.md](hack/MAINTAINERS.md)
### Sign your work
The sign-off is a simple line at the end of the explanation for the
patch, which certifies that you wrote it or otherwise have the right to
pass it on as an open-source patch. The rules are pretty simple: if you
can certify the below (from
[developercertificate.org](http://developercertificate.org/)):
```
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
```
then you just add a line to every git commit message:
Docker-DCO-1.1-Signed-off-by: Joe Smith <joe.smith@email.com> (github: github_handle)
using your real name (sorry, no pseudonyms or anonymous contributions.)
One way to automate this, is customise your get ``commit.template`` by adding
a ``prepare-commit-msg`` hook to your docker checkout:
```
curl -o .git/hooks/prepare-commit-msg https://raw.github.com/dotcloud/docker/master/contrib/prepare-commit-msg.hook && chmod +x .git/hooks/prepare-commit-msg
```
* Note: the above script expects to find your GitHub user name in ``git config --get github.user``
#### Small patch exception
There are several exceptions to the signing requirement. Currently these are:
* Your patch fixes spelling or grammar errors.
* Your patch is a single line change to documentation.
If you have any questions, please refer to the FAQ in the [docs](http://docs.docker.io)
### How can I become a maintainer?
* Step 1: learn the component inside out
* Step 2: make yourself useful by contributing code, bugfixes, support etc.
* Step 3: volunteer on the irc channel (#docker@freenode)
* Step 4: propose yourself at a scheduled docker meeting in #docker-dev
Don't forget: being a maintainer is a time investment. Make sure you will have time to make yourself available.
You don't have to be a maintainer to make a difference on the project!

## FIXME
This file is a loose collection of things to improve in the codebase, for the internal
use of the maintainers.
They are not big enough to be in the roadmap, not user-facing enough to be github issues,
and not important enough to be discussed in the mailing list.
They are just like FIXME comments in the source code, except we're not sure where in the source
to put them - so we put them here :)
* Run linter on codebase
* Unify build commands and regular commands
* Move source code into src/ subdir for clarity
* docker build: on non-existent local path for ADD, don't show full absolute path on the host
* use size header for progress bar in pull
* Clean up context upload in build!!!
* Parallel pull
* Upgrade dockerd without stopping containers
* Simple command to remove all untagged images (`docker rmi $(docker images | awk '/^<none>/ { print $3 }')`)
* Simple command to clean up containers for disk space
* Clean up the ProgressReader api, it's a PITA to use

Docker: the Linux container engine
==================================
Docker: the Linux container runtime
===================================
Docker is an open source project to pack, ship and run any application
as a lightweight container
Docker complements LXC with a high-level API which operates at the process level. It runs unix processes with strong guarantees of isolation and repeatability across servers.
Docker containers are both *hardware-agnostic* and *platform-agnostic*.
This means that they can run anywhere, from your laptop to the largest
EC2 compute instance and everything in between - and they don't require
that you use a particular language, framework or packaging system. That
makes them great building blocks for deploying and scaling web apps,
databases and backend services without depending on a particular stack
or provider.
Docker is a great building block for automating distributed systems: large-scale web deployments, database clusters, continuous deployment systems, private PaaS, service-oriented architectures, etc.
Docker is an open-source implementation of the deployment engine which
powers [dotCloud](http://dotcloud.com), a popular Platform-as-a-Service.
It benefits directly from the experience accumulated over several years
of large-scale operation and support of hundreds of thousands of
applications and databases.
![Docker L](docs/sources/static_files/lego_docker.jpg "Docker")
![Docker L](docs/theme/mkdocs/img/logo_compressed.png "Docker")
* *Heterogeneous payloads*: any combination of binaries, libraries, configuration files, scripts, virtualenvs, jars, gems, tarballs, you name it. No more juggling between domain-specific tools. Docker can deploy and run them all.
## Better than VMs
* *Any server*: docker can run on any x64 machine with a modern linux kernel - whether it's a laptop, a bare metal server or a VM. This makes it perfect for multi-cloud deployments.
A common method for distributing applications and sandboxing their
execution is to use virtual machines, or VMs. Typical VM formats are
VMWare's vmdk, Oracle Virtualbox's vdi, and Amazon EC2's ami. In theory
these formats should allow every developer to automatically package
their application into a "machine" for easy distribution and deployment.
In practice, that almost never happens, for a few reasons:
* *Isolation*: docker isolates processes from each other and from the underlying host, using lightweight containers.
* *Size*: VMs are very large which makes them impractical to store
and transfer.
* *Performance*: running VMs consumes significant CPU and memory,
which makes them impractical in many scenarios, for example local
development of multi-tier applications, and large-scale deployment
of cpu and memory-intensive applications on large numbers of
machines.
* *Portability*: competing VM environments don't play well with each
other. Although conversion tools do exist, they are limited and
add even more overhead.
* *Hardware-centric*: VMs were designed with machine operators in
mind, not software developers. As a result, they offer very
limited tooling for what developers need most: building, testing
and running their software. For example, VMs offer no facilities
for application versioning, monitoring, configuration, logging or
service discovery.
By contrast, Docker relies on a different sandboxing method known as
*containerization*. Unlike traditional virtualization, containerization
takes place at the kernel level. Most modern operating system kernels
now support the primitives necessary for containerization, including
Linux with [openvz](http://openvz.org),
[vserver](http://linux-vserver.org) and more recently
[lxc](http://lxc.sourceforge.net), Solaris with
[zones](http://docs.oracle.com/cd/E26502_01/html/E29024/preface-1.html#scrolltoc)
and FreeBSD with
[Jails](http://www.freebsd.org/doc/handbook/jails.html).
Docker builds on top of these low-level primitives to offer developers a
portable format and runtime environment that solves all 4 problems.
Docker containers are small (and their transfer can be optimized with
layers), they have basically zero memory and cpu overhead, they are
completely portable and are designed from the ground up with an
application-centric design.
The best part: because Docker operates at the OS level, it can still be
run inside a VM!
## Plays well with others
Docker does not require that you buy into a particular programming
language, framework, packaging system or configuration language.
Is your application a Unix process? Does it use files, tcp connections,
environment variables, standard Unix streams and command-line arguments
as inputs and outputs? Then Docker can run it.
Can your application's build be expressed as a sequence of such
commands? Then Docker can build it.
## Escape dependency hell
A common problem for developers is the difficulty of managing all
their application's dependencies in a simple and automated way.
This is usually difficult for several reasons:
* *Cross-platform dependencies*. Modern applications often depend on
a combination of system libraries and binaries, language-specific
packages, framework-specific modules, internal components
developed for another project, etc. These dependencies live in
different "worlds" and require different tools - these tools
typically don't work well with each other, requiring awkward
custom integrations.
* Conflicting dependencies. Different applications may depend on
different versions of the same dependency. Packaging tools handle
these situations with various degrees of ease - but they all
handle them in different and incompatible ways, which again forces
the developer to do extra work.
* Custom dependencies. A developer may need to prepare a custom
version of their application's dependency. Some packaging systems
can handle custom versions of a dependency, others can't - and all
of them handle it differently.
* *Repeatability*: because containers are isolated in their own filesystem, they behave the same regardless of where, when, and alongside what they run.
Docker solves dependency hell by giving the developer a simple way to
express *all* their application's dependencies in one place, and
streamline the process of assembling them. If this makes you think of
[XKCD 927](http://xkcd.com/927/), don't worry. Docker doesn't
*replace* your favorite packaging systems. It simply orchestrates
their use in a simple and repeatable way. How does it do that? With
layers.
Notable features
-----------------
Docker defines a build as running a sequence of Unix commands, one
after the other, in the same container. Build commands modify the
contents of the container (usually by installing new files on the
filesystem), the next command modifies it some more, etc. Since each
build command inherits the result of the previous commands, the
*order* in which the commands are executed expresses *dependencies*.
* Filesystem isolation: each process container runs in a completely separate root filesystem.
Here's a typical Docker build process:
* Resource isolation: system resources like cpu and memory can be allocated differently to each process container, using cgroups.
* Network isolation: each process container runs in its own network namespace, with a virtual interface and IP address of its own.
* Copy-on-write: root filesystems are created using copy-on-write, which makes deployment extremely fast, memory-cheap and disk-cheap.
* Logging: the standard streams (stdout/stderr/stdin) of each process container are collected and logged for real-time or batch retrieval.
* Change management: changes to a container's filesystem can be committed into a new image and re-used to create more containers. No templating or manual configuration required.
* Interactive shell: docker can allocate a pseudo-tty and attach to the standard input of any container, for example to run a throwaway interactive shell.
Install instructions
==================
Quick install on Ubuntu 12.04 and 12.10
---------------------------------------
```bash
FROM ubuntu:12.04
RUN apt-get update
RUN apt-get install -q -y python python-pip curl
RUN curl -L https://github.com/shykes/helloflask/archive/master.tar.gz | tar -xzv
RUN cd helloflask-master && pip install -r requirements.txt
curl get.docker.io | sh -x
```
Note that Docker doesn't care *how* dependencies are built - as long
as they can be built by running a Unix command in a container.
Binary installs
----------------
Docker supports the following binary installation methods.
Note that some methods are community contributions and not yet officially supported.
Getting started
===============
* [Ubuntu 12.04 and 12.10 (officially supported)](http://docs.docker.io/en/latest/installation/ubuntulinux/)
* [Arch Linux](http://docs.docker.io/en/latest/installation/archlinux/)
* [MacOS X (with Vagrant)](http://docs.docker.io/en/latest/installation/macos/)
* [Windows (with Vagrant)](http://docs.docker.io/en/latest/installation/windows/)
* [Amazon EC2 (with Vagrant)](http://docs.docker.io/en/latest/installation/amazon/)
Docker can be installed on your local machine as well as servers - both
bare metal and virtualized. It is available as a binary on most modern
Linux systems, or as a VM on Windows, Mac and other systems.
Installing from source
----------------------
We also offer an interactive tutorial for quickly learning the basics of
using Docker.
1. Make sure you have a [Go language](http://golang.org/doc/install) compiler and [git](http://git-scm.com) installed.
For up-to-date install instructions and online tutorials, see the
[Getting Started page](http://www.docker.io/gettingstarted/).
2. Checkout the source code
```bash
git clone http://github.com/dotcloud/docker
```
3. Build the docker binary
```bash
cd docker
make VERBOSE=1
sudo cp ./bin/docker /usr/local/bin/docker
```
Usage examples
==============
Docker can be used to run short-lived commands, long-running daemons
(app servers, databases etc.), interactive shell sessions, etc.
First run the docker daemon
---------------------------
You can find a [list of real-world
examples](http://docs.docker.io/en/latest/examples/) in the
documentation.
All the examples assume your machine is running the docker daemon. To run the docker daemon in the background, simply type:
```bash
# On a production system you want this running in an init script
sudo docker -d &
```
Now you can run docker in client mode: all commands will be forwarded to the docker daemon, so the client can run from any account.
```bash
# Now you can run docker commands from any account.
docker help
```
Throwaway shell in a base ubuntu image
--------------------------------------
```bash
docker pull ubuntu:12.10
# Run an interactive shell, allocate a tty, attach stdin and stdout
# To detach the tty without exiting the shell, use the escape sequence Ctrl-p + Ctrl-q
docker run -i -t ubuntu:12.10 /bin/bash
```
Starting a long-running worker process
--------------------------------------
```bash
# Start a very useful long-running process
JOB=$(docker run -d ubuntu /bin/sh -c "while true; do echo Hello world; sleep 1; done")
# Collect the output of the job so far
docker logs $JOB
# Kill the job
docker kill $JOB
```
Running an irc bouncer
----------------------
```bash
BOUNCER_ID=$(docker run -d -p 6667 -u irc shykes/znc $USER $PASSWORD)
echo "Configure your irc client to connect to port $(docker port $BOUNCER_ID 6667) of this machine"
```
Running Redis
-------------
```bash
REDIS_ID=$(docker run -d -p 6379 shykes/redis redis-server)
echo "Configure your redis client to connect to port $(docker port $REDIS_ID 6379) of this machine"
```
Share your own image!
---------------------
```bash
CONTAINER=$(docker run -d ubuntu:12.10 apt-get install -y curl)
docker commit -m "Installed curl" $CONTAINER $USER/betterbase
docker push $USER/betterbase
```
A list of publicly available images is [available here](https://github.com/dotcloud/docker/wiki/Public-docker-images).
Expose a service on a TCP port

```bash
# Expose port 4444 of this container, and tell netcat to listen on it
JOB=$(docker run -d -p 4444 base /bin/nc -l -p 4444)
# Which public port is NATed to my container?
PORT=$(docker port $JOB 4444)
# Connect to the public port via the host's public address
# Please note that because of how routing works connecting to localhost or 127.0.0.1 $PORT will not work.
IP=$(ifconfig eth0 | perl -n -e 'if (m/inet addr:([\d\.]+)/g) { print $1 }')
echo hello world | nc $IP $PORT
# Verify that the network connection worked
echo "Daemon received: $(docker logs $JOB)"

Under the hood
--------------
Under the hood, Docker is built on the following components:
* The
[cgroup](http://blog.dotcloud.com/kernel-secrets-from-the-paas-garage-part-24-c)
and
[namespacing](http://blog.dotcloud.com/under-the-hood-linux-kernels-on-dotcloud-part)
capabilities of the Linux kernel;
* The [Go](http://golang.org) programming language.
* The [cgroup](http://blog.dotcloud.com/kernel-secrets-from-the-paas-garage-part-24-c) and [namespacing](http://blog.dotcloud.com/under-the-hood-linux-kernels-on-dotcloud-part) capabilities of the Linux kernel;
* [AUFS](http://aufs.sourceforge.net/aufs.html), a powerful union filesystem with copy-on-write capabilities;
* The [Go](http://golang.org) programming language;
* [lxc](http://lxc.sourceforge.net/), a set of convenience scripts to simplify the creation of linux containers.

Setting up a dev environment
----------------------------
Instructions that have been verified to work on Ubuntu 12.10,
```bash
sudo apt-get -y install lxc wget bsdtar curl golang git
export GOPATH=~/go/
export PATH=$GOPATH/bin:$PATH
mkdir -p $GOPATH/src/github.com/dotcloud
cd $GOPATH/src/github.com/dotcloud
git clone git@github.com:dotcloud/docker.git
cd docker
go get -v github.com/dotcloud/docker/...
go install -v github.com/dotcloud/docker/...
```
Then run the docker daemon,
```bash
sudo $GOPATH/bin/docker -d
```
Run the `go install` command (above) to recompile docker.
What is a Standard Container?
=============================
Docker defines a unit of software delivery called a Standard Container. The goal of a Standard Container is to encapsulate a software component and all its dependencies in
a format that is self-describing and portable, so that any compliant runtime can run it without extra dependencies, regardless of the underlying machine and the contents of the container.
The spec for Standard Containers is currently a work in progress, but it is very straightforward. It mostly defines 1) an image format, 2) a set of standard operations, and 3) an execution environment.
A great analogy for this is the shipping container. Just like Standard Containers are a fundamental unit of software delivery, shipping containers (http://bricks.argz.com/ins/7823-1/12) are a fundamental unit of physical delivery.
### 1. STANDARD OPERATIONS
Just like shipping containers, Standard Containers define a set of STANDARD OPERATIONS. Shipping containers can be lifted, stacked, locked, loaded, unloaded and labelled. Similarly, standard containers can be started, stopped, copied, snapshotted, downloaded, uploaded and tagged.
### 2. CONTENT-AGNOSTIC
Just like shipping containers, Standard Containers are CONTENT-AGNOSTIC: all standard operations have the same effect regardless of the contents. A shipping container will be stacked in exactly the same way whether it contains Vietnamese powder coffee or spare Maserati parts. Similarly, Standard Containers are started or uploaded in the same way whether they contain a postgres database, a php application with its dependencies and application server, or Java build artifacts.
### 3. INFRASTRUCTURE-AGNOSTIC
Both types of containers are INFRASTRUCTURE-AGNOSTIC: they can be transported to thousands of facilities around the world, and manipulated by a wide variety of equipment. A shipping container can be packed in a factory in Ukraine, transported by truck to the nearest routing center, stacked onto a train, loaded into a German boat by an Australian-built crane, stored in a warehouse at a US facility, etc. Similarly, a standard container can be bundled on my laptop, uploaded to S3, downloaded, run and snapshotted by a build server at Equinix in Virginia, uploaded to 10 staging servers in a home-made Openstack cluster, then sent to 30 production instances across 3 EC2 regions.
### 4. DESIGNED FOR AUTOMATION
Because they offer the same standard operations regardless of content and infrastructure, Standard Containers, just like their physical counterpart, are extremely well-suited for automation. In fact, you could say automation is their secret weapon.
Many things that once required time-consuming and error-prone human effort can now be programmed. Before shipping containers, a bag of powder coffee was hauled, dragged, dropped, rolled and stacked by 10 different people in 10 different locations by the time it reached its destination. 1 out of 50 disappeared. 1 out of 20 was damaged. The process was slow, inefficient and cost a fortune - and was entirely different depending on the facility and the type of goods.
Similarly, before Standard Containers, by the time a software component ran in production, it had been individually built, configured, bundled, documented, patched, vendored, templated, tweaked and instrumented by 10 different people on 10 different computers. Builds failed, libraries conflicted, mirrors crashed, post-it notes were lost, logs were misplaced, cluster updates were half-broken. The process was slow, inefficient and cost a fortune - and was entirely different depending on the language and infrastructure provider.
### 5. INDUSTRIAL-GRADE DELIVERY
There are 17 million shipping containers in existence, packed with every physical good imaginable. Every single one of them can be loaded on the same boats, by the same cranes, in the same facilities, and sent anywhere in the World with incredible efficiency. It is embarrassing to think that a 30 ton shipment of coffee can safely travel half-way across the World in *less time* than it takes a software team to deliver its code from one datacenter to another sitting 10 miles away.
With Standard Containers we can put an end to that embarrassment, by making INDUSTRIAL-GRADE DELIVERY of software a reality.
Standard Container Specification
--------------------------------
(TODO)
### Image format
### Standard operations
* Copy
* Run
* Stop
* Wait
* Commit
* Attach standard streams
* List filesystem changes
* ...
### Execution environment
#### Root filesystem
#### Environment variables
#### Process arguments
#### Networking
#### Process namespacing
#### Resource limits
#### Process monitoring
#### Logging
#### Signals
#### Pseudo-terminal allocation
#### Security
Use and transfer of Docker may be subject to certain restrictions by the
United States and other governments.

## Spec for data volumes
Spec owner: Solomon Hykes <solomon@dotcloud.com>
Data volumes (issue #111) are a much-requested feature which trigger much discussion and debate. Below is the current authoritative spec for implementing data volumes.
This spec will be deprecated once the feature is fully implemented.
Discussion, requests, trolls, demands, offerings, threats and other forms of supplications concerning this spec should be addressed to Solomon here: https://github.com/dotcloud/docker/issues/111
### 1. Creating data volumes
At container creation, parts of a container's filesystem can be mounted as separate data volumes. Volumes are defined with the -v flag.
For example:
```bash
$ docker run -v /var/lib/postgres -v /var/log postgres /usr/bin/postgres
```
In this example, a new container is created from the 'postgres' image. At the same time, docker creates 2 new data volumes: one will be mapped to the container at /var/lib/postgres, the other at /var/log.
2 important notes:
1) Volumes don't have top-level names. At no point does the user provide a name, or is a name given to him. Volumes are identified by the path at which they are mounted inside their container.
2) The user doesn't choose the source of the volume. Docker only mounts volumes it created itself, in the same way that it only runs containers that it created itself. That is by design.
### 2. Sharing data volumes
Instead of creating its own volumes, a container can share another container's volumes. For example:
```bash
$ docker run --volumes-from $OTHER_CONTAINER_ID postgres /usr/local/bin/postgres-backup
```
In this example, a new container is created from the 'postgres' example. At the same time, docker will *re-use* the 2 data volumes created in the previous example. One volume will be mounted on the /var/lib/postgres of *both* containers, and the other will be mounted on the /var/log of both containers.
### 3. Under the hood
Docker stores volumes in /var/lib/docker/volumes. Each volume receives a globally unique ID at creation, and is stored at /var/lib/docker/volumes/ID.
At creation, volumes are attached to a single container - the source of truth for this mapping will be the container's configuration.
Mounting a volume consists of calling "mount --bind" from the volume's directory to the appropriate sub-directory of the container mountpoint. This may be done by Docker itself, or farmed out to lxc (which supports mount-binding) if possible.
### 4. Backups, transfers and other volume operations
Volumes sometimes need to be backed up, transfered between hosts, synchronized, etc. These operations typically are application-specific or site-specific, eg. rsync vs. S3 upload vs. replication vs...
Rather than attempting to implement all these scenarios directly, Docker will allow for custom implementations using an extension mechanism.
### 5. Custom volume handlers
Docker allows for arbitrary code to be executed against a container's volumes, to implement any custom action: backup, transfer, synchronization across hosts, etc.
Here's an example:
```bash
$ DB=$(docker run -d -v /var/lib/postgres -v /var/log postgres /usr/bin/postgres)
$ BACKUP_JOB=$(docker run -d --volumes-from $DB shykes/backuper /usr/local/bin/backup-postgres --s3creds=$S3CREDS)
$ docker wait $BACKUP_JOB
```
Congratulations, you just implemented a custom volume handler, using Docker's built-in ability to 1) execute arbitrary code and 2) share volumes between containers.

Buildbot
========
Buildbot is a continuous integration system designed to automate the
build/test cycle. By automatically rebuilding and testing the tree each time
something has changed, build problems are pinpointed quickly, before other
developers are inconvenienced by the failure.
When running 'make hack' at the docker root directory, it spawns a virtual
machine in the background running a buildbot instance and adds a git
post-commit hook that automatically run docker tests for you.
You can check your buildbot instance at http://192.168.33.21:8010/waterfall
Buildbot dependencies

# docker-build: build your software with docker
## Description
docker-build is a script to build docker images from source. It will be deprecated once the 'build' feature is incorporated into docker itself (See https://github.com/dotcloud/docker/issues/278)
Author: Solomon Hykes <solomon@dotcloud.com>
## Install
docker-builder requires:
1) A reasonably recent Python setup (tested on 2.7.2).
2) A running docker daemon at version 0.1.4 or more recent (http://www.docker.io/gettingstarted)
## Usage
First create a valid Changefile, which defines a sequence of changes to apply to a base image.
$ cat Changefile
# Start build from a know base image
from base:ubuntu-12.10
# Update ubuntu sources
run echo 'deb http://archive.ubuntu.com/ubuntu quantal main universe multiverse' > /etc/apt/sources.list
run apt-get update
# Install system packages
run DEBIAN_FRONTEND=noninteractive apt-get install -y -q git
run DEBIAN_FRONTEND=noninteractive apt-get install -y -q curl
run DEBIAN_FRONTEND=noninteractive apt-get install -y -q golang
# Insert files from the host (./myscript must be present in the current directory)
copy myscript /usr/local/bin/myscript
Run docker-build, and pass the contents of your Changefile as standard input.
$ IMG=$(./docker-build < Changefile)
This will take a while: for each line of the changefile, docker-build will:
1. Create a new container to execute the given command or insert the given file
2. Wait for the container to complete execution
3. Commit the resulting changes as a new image
4. Use the resulting image as the input of the next step
If all the steps succeed, the result will be an image containing the combined results of each build step.
You can trace back those build steps by inspecting the image's history:
$ docker history $IMG
ID CREATED CREATED BY
1e9e2045de86 A few seconds ago /bin/sh -c cat > /usr/local/bin/myscript; chmod +x /usr/local/bin/git
77db140aa62a A few seconds ago /bin/sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -q golang
77db140aa62a A few seconds ago /bin/sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -q curl
77db140aa62a A few seconds ago /bin/sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -q git
83e85d155451 A few seconds ago /bin/sh -c apt-get update
bfd53b36d9d3 A few seconds ago /bin/sh -c echo 'deb http://archive.ubuntu.com/ubuntu quantal main universe multiverse' > /etc/apt/sources.list
base 2 weeks ago /bin/bash
27cf78414709 2 weeks ago
Note that your build started from 'base', as instructed by your Changefile. But that base image itself seems to have been built in 2 steps - hence the extra step in the history.
You can use this build technique to create any image you want: a database, a web application, or anything else that can be build by a sequence of unix commands - in other words, anything else.

# Generating man pages from the Markdown files
The recommended approach for generating the man pages is via a Docker
container. Using the supplied Dockerfile, Docker will create a Fedora based
container and isolate the Pandoc installation. This is a seamless process,
saving you from dealing with Pandoc and dependencies on your own computer.
## Building the Fedora / Pandoc image
There is a Dockerfile provided in the `docker/contrib/man/md` directory.
Using this Dockerfile, create a Docker image tagged `fedora/pandoc`:
docker build -t fedora/pandoc .
## Utilizing the Fedora / Pandoc image
Once the image is built, run a container using the image with *volumes*:
docker run -v /<path-to-git-dir>/docker/contrib/man:/pandoc:rw \
-w /pandoc -i fedora/pandoc /pandoc/md/md2man-all.sh
The Pandoc Docker container will process the Markdown files and generate
the man pages inside the `docker/contrib/man/man1` directory using
Docker volumes. For more information on Docker volumes see the man page for
`docker run` and also look at the article [Sharing Directories via Volumes]
(http://docs.docker.io/use/working_with_volumes/).

# NAME
docker-attach - Attach to a running container
# SYNOPSIS
**docker attach** **--no-stdin**[=*false*] **--sig-proxy**[=*true*] CONTAINER
# DESCRIPTION
If you **docker run** a container in detached mode (**-d**), you can reattach to
the detached container with **docker attach** using the container's ID or name.
You can detach from the container again (and leave it running) with `CTRL-c` (for
a quiet exit) or `CTRL-\` to get a stacktrace of the Docker client when it quits.
When you detach from a container the exit code will be returned to
the client.
# OPTIONS
**--no-stdin**=*true*|*false*
When set to true, do not attach to stdin. The default is *false*.
**--sig-proxy**=*true*|*false*:
When set to true, proxify all received signal to the process (even in non-tty
mode). The default is *true*.
# EXAMPLES
## Attaching to a container
In this example the top command is run inside a container, from an image called
fedora, in detached mode. The ID from the container is passed into the **docker
attach** command:
# ID=$(sudo docker run -d fedora /usr/bin/top -b)
# sudo docker attach $ID

# NAME
docker-build - Build a container image from a Dockerfile source at PATH
# SYNOPSIS
**docker build** [**--no-cache**[=*false*]] [**-q**|**--quiet**[=*false*]]
[**--rm**] [**-t**|**--tag**=TAG] PATH | URL | -
# DESCRIPTION
This will read the Dockerfile from the directory specified in **PATH**.
It also sends any other files and directories found in the current
directory to the Docker daemon. The contents of this directory would
be used by **ADD** commands found within the Dockerfile.
Warning, this will send a lot of data to the Docker daemon depending
on the contents of the current directory. The build is run by the Docker
daemon, not by the CLI, so the whole context must be transferred to the daemon.
The Docker CLI reports "Uploading context" when the context is sent to
the daemon.
When a single Dockerfile is given as the URL, then no context is set.
When a Git repository is set as the **URL**, the repository is used
as context.
# OPTIONS
**-q**, **--quiet**=*true*|*false*
When set to true, suppress verbose build output. Default is *false*.
**--rm**=*true*|*false*
When true, remove intermediate containers that are created during the
build process. The default is true.
**-t**, **--tag**=*tag*
Tag to be applied to the resulting image on successful completion of
the build.
**--no-cache**=*true*|*false*
When set to true, do not use a cache when building the image. The
default is *false*.
# EXAMPLES
## Building an image using a Dockefile located inside the current directory
Docker images can be built using the build command and a Dockerfile:
docker build .
During the build process Docker creates intermediate images. In order to
keep them, you must explicitly set `--rm=false`.
docker build --rm=false .
A good practice is to make a sub-directory with a related name and create
the Dockerfile in that directory. For example, a directory called mongo may
contain a Dockerfile to create a Docker MongoDB image. Likewise, another
directory called httpd may be used to store Dockerfiles for Apache web
server images.
It is also a good practice to add the files required for the image to the
sub-directory. These files will then be specified with the `ADD` instruction
in the Dockerfile. Note: If you include a tar file (a good practice!), then
Docker will automatically extract the contents of the tar file
specified within the `ADD` instruction into the specified target.
## Building an image using a URL
This will clone the specified Github repository from the URL and use it
as context. The Dockerfile at the root of the repository is used as
Dockerfile. This only works if the Github repository is a dedicated
repository.
docker build github.com/scollier/Fedora-Dockerfiles/tree/master/apache
Note: You can set an arbitrary Git repository via the `git://` schema.

# NAME
docker-images - List the images in the local repository
# SYNOPSIS
**docker images**
[**-a**|**--all**=*false*]
[**--no-trunc**[=*false*]
[**-q**|**--quiet**[=*false*]
[**-t**|**--tree**=*false*]
[**-v**|**--viz**=*false*]
[NAME]
# DESCRIPTION
This command lists the images stored in the local Docker repository.
By default, intermediate images, used during builds, are not listed. Some of the
output, e.g. image ID, is truncated, for space reasons. However the truncated
image ID, and often the first few characters, are enough to be used in other
Docker commands that use the image ID. The output includes repository, tag, image
ID, date created and the virtual size.
The title REPOSITORY for the first title may seem confusing. It is essentially
the image name. However, because you can tag a specific image, and multiple tags
(image instances) can be associated with a single name, the name is really a
repository for all tagged images of the same name. For example consider an image
called fedora. It may be tagged with 18, 19, or 20, etc. to manage different
versions.
# OPTIONS
**-a**, **--all**=*true*|*false*
When set to true, also include all intermediate images in the list. The
default is false.
**--no-trunc**=*true*|*false*
When set to true, list the full image ID and not the truncated ID. The
default is false.
**-q**, **--quiet**=*true*|*false*
When set to true, list the complete image ID as part of the output. The
default is false.
**-t**, **--tree**=*true*|*false*
When set to true, list the images in a tree dependency tree (hierarchy)
format. The default is false.
**-v**, **--viz**=*true*|*false*
When set to true, list the graph in graphviz format. The default is
*false*.
# EXAMPLES
## Listing the images
To list the images in a local repository (not the registry) run:
docker images
The list will contain the image repository name, a tag for the image, and an
image ID, when it was created and its virtual size. Columns: REPOSITORY, TAG,
IMAGE ID, CREATED, and VIRTUAL SIZE.
To get a verbose list of images which contains all the intermediate images
used in builds use **-a**:
docker images -a
## List images dependency tree hierarchy
To list the images in the local repository (not the registry) in a dependency
tree format, use the **-t** option.
docker images -t
This displays a staggered hierarchy tree where the less indented image is
the oldest with dependent image layers branching inward (to the right) on
subsequent lines. The newest or top level image layer is listed last in
any tree branch.
## List images in GraphViz format
To display the list in a format consumable by a GraphViz tools run with
**-v**. For example to produce a .png graph file of the hierarchy use:
docker images --viz | dot -Tpng -o docker.png
## Listing only the shortened image IDs
Listing just the shortened image IDs. This can be useful for some automated
tools.
docker images -q

# SYNOPSIS
**docker info**
# DESCRIPTION
This command displays system wide information regarding the Docker installation.
Information displayed includes the number of containers and images, pool name,
data file, metadata file, data space used, total data space, metadata space used
, total metadata space, execution driver, and the kernel version.
The data file is where the images are stored and the metadata file is where the
meta data regarding those images are stored. When run for the first time Docker
allocates a certain amount of data space and meta data space from the space
available on the volume where `/var/lib/docker` is mounted.
# OPTIONS
There are no available options.
# EXAMPLES
## Display Docker system information
Here is a sample output:
# docker info
