-Introduction
-============
-
-Docker -- The Linux container runtime
--------------------------------------
-
-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 is a great building block for automating distributed systems: large-scale web deployments, database clusters, continuous deployment systems, private PaaS, service-oriented architectures, etc.
-
-
-- **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.
-- **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.
-- **Isolation** docker isolates processes from each other and from the underlying host, using lightweight containers.
-- **Repeatability** Because containers are isolated in their own filesystem, they behave the same regardless of where, when, and alongside what they run.

-
-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 dependency, regardless of the underlying machine and the contents of the container.
-
-The spec for Standard Containers is currently 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.
-
-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.
-
-
-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.
-
-
-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.
-
-
-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.
-
-
-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.

-To use Docker Builder, assemble the steps into a text file (commonly referred to
-as a Dockerfile) and supply this to `docker build` on STDIN, like so:
+To build an image from a source repository, create a description file called `Dockerfile`
+at the root of your repository. This file will describe the steps to assemble

-    ``docker build - < Dockerfile``
+Then call `docker build` with the path of your source repository as argument:
+
+    ``docker build .``
+
+You can specify a repository and tag at which to save the new image if the
+build succeeds:
+
+    ``docker build -t shykes/myapp .``

     ``ADD <src> <dest>``
 
-The `ADD` instruction will insert the files from the `<src>` path of the context into `<dest>` path 
-of the container.
-The context must be set in order to use this instruction. (see examples)
+The `ADD` instruction will copy new files from <src> and add them to the container's filesystem at path `<dest>`.
+
+`<src>` must be the path to a file or directory relative to the source directory being built (also called the
+context of the build).
+
+`<dest>` is the path at which the source will be copied in the destination container.
+
+The copy obeys the following rules:
+
+If `<src>` is a directory, the entire directory is copied, including filesystem metadata.
+
+If `<src>` is a tar archive in a recognized compression format (identity, gzip, bzip2 or xz), it
+is unpacked as a directory.
+
+When a directory is copied or unpacked, it has the same behavior as 'tar -x': the result is the union of
+a) whatever existed at the destination path and b) the contents of the source tree, with conflicts resolved
+in favor of b on a file-by-file basis.
+
+If `<src>` is any other kind of file, it is copied individually along with its metadata. In this case,
+if `<dst>` ends with a trailing slash '/', it will be considered a directory and the contents of `<src>`
+will be written at `<dst>/base(<src>)`.
+If `<dst>` does not end with a trailing slash, it will be considered a regular file and the contents
+of `<src>` will be written at `<dst>`.
+
+If `<dest>` doesn't exist, it is created along with all missing directories in its path. All new
+files and directories are created with mode 0700, uid and gid 0.

+Port redirection
+================
+
+Docker can redirect public tcp ports to your container, so it can be reached over the network.
+Port redirection is done on ``docker run`` using the -p flag.
+
+A port redirect is specified as PUBLIC:PRIVATE, where tcp port PUBLIC will be redirected to
+tcp port PRIVATE. As a special case, the public port can be omitted, in which case a random
+public port will be allocated.
+
+.. code-block:: bash
+
+    # A random PUBLIC port is redirected to PRIVATE port 80 on the container
+    docker run -p 80 <image> <cmd>
+
+    # PUBLIC port 80 is redirected to PRIVATE port 80
+    docker run -p 80:80 <image> <cmd>
+

+Default port redirects can be built into a container with the EXPOSE build command.
