Docker: the Linux container engine
|

==================================

applications as highly portable, self-sufficient containers.
|
||||
|

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.

## Better than VMs
|
||||
|
||||
A common method for distributing applications and sandbox 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:

* *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.

## Escape dependency hell

|

A common problem for developers is the difficulty of managing all their application's dependencies in a simple and automated way.

A common problem for developers is the difficulty of managing all

|
||||
|
||||
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.

|
||||
others can't - and all of them handle it differently.

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.

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*.

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 how 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.

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 onto 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.
