+# A simple helper script to help people build seccomp profiles for
+# Docker/LXC.  The goal is mostly to reduce the attack surface to the
+# kernel, by restricting access to rarely used, recently added or not used
+# syscalls.
+#
+# This script processes one or more files which contain the list of system
+# calls to be allowed.  See mkseccomp.sample for more information how you
+# can configure the list of syscalls.  When run, this script produces output
+# which, when stored in a file, can be passed to docker as follows:
+#
+# docker run -lxc-conf="lxc.seccomp=$file" <rest of arguments>
+#
+# The included sample file shows how to cut about a quarter of all syscalls,
+# which affecting most applications.
+#
+# For specific situations it is possible to reduce the list further. By
+# reducing the list to just those syscalls required by a certain application
+# you can make it difficult for unknown/unexpected code to run.
+#
+# Run this script as follows:
+#
+# ./mkseccomp.pl < mkseccomp.sample >syscalls.list
+# or
+# ./mkseccomp.pl mkseccomp.sample >syscalls.list
+#
+# Multiple files can be specified, in which case the lists of syscalls are
+# combined.
+#

+/* This sample file is an example for mkseccomp.pl to produce a seccomp file
+ * which restricts syscalls that are only useful for an admin but allows the
+ * vast majority of normal userspace programs to run normally.
+ *
+ * The format of this file is one line per syscall.  This is then processed
+ * and passed to 'cpp' to convert the names to numbers using whatever is
+ * correct for your platform.  As such C-style comments are permitted.  Note
+ * this also means that C preprocessor macros are also allowed.  So it is
+ * possible to create groups surrounded by #ifdef/#endif and control their
+ * inclusion via #define (not #include).
+ *
+ * Syscalls that don't exist on your architecture are silently filtered out.
+ * Syscalls marked with (*) are required for a container to spawn a bash
+ * shell successfully (not necessarily full featured).  Listing the same
+ * syscall multiple times is no problem.
+ *
+ * If you want to make a list specifically for one application the easiest
+ * way is to run the application under strace, like so:
+ *
+ * $ strace -f -q -c -o strace.out application args...
+ *
+ * Once you have a reasonable sample of the execution of the program, exit
+ * it.  The file strace.out will have a summary of the syscalls used.  Copy
+ * that list into this file, comment out everything else except the starred
+ * syscalls (which you need for the container to start) and you're done.
+ *
+ * To get the list of syscalls from the strace output this works well for
+ * me
+ *
+ * $ cut -c52 < strace.out
+ *
+ * This sample list was compiled as a combination of all the syscalls
+ * available on i386 and amd64 on Ubuntu Precise, as such it may not contain
+ * everything and not everything may be relevent for your system.  This
+ * shouldn't be a problem.

 * [vagrant-shell](https://github.com/destructuring/vagrant-shell)
+
+## Setting up Vagrant-docker with the Remote API
+
+The initial Docker upstart script will not work because it runs on `127.0.0.1`, which is not accessible to the host machine. Instead, we need to change the script to connect to `0.0.0.0`. To do this, modify `/etc/init/docker.conf` to look like this:
+
+```
+description     "Docker daemon"
+
+start on filesystem and started lxc-net
+stop on runlevel [!2345]
+
+respawn
+
+script
+    /usr/bin/docker -d -H=tcp://0.0.0.0:4243/
+end script
+```
+
+Once that's done, you need to set up a SSH tunnel between your host machine and the vagrant machine that's running Docker. This can be done by running the following command in a host terminal:
+
+```
+ssh -L 4243:localhost:4243 -p 2222 vagrant@localhost
+```
+
+(The first 4243 is what your host can connect to, the second 4243 is what port Docker is running on in the vagrant machine, and the 2222 is the port Vagrant is providing for SSH. If VirtualBox is the VM you're using, you can see what value "2222" should be by going to: Network > Adapter 1 > Advanced > Port Forwarding in the VirtualBox GUI.)
+
+Note that because the port has been changed, to run docker commands from within the command line you must run them like this:
+
+```
+sudo docker -H 0.0.0.0:4243 < commands for docker >
+```

+
+The code is under development. Contributions in the form of suggestions,
+code-reviews, and patches are welcome.
+
+Please send the communication to gurjeet@singh.im and CC at least one Docker

 - **vendor registry**: such a registry is provided by a software vendor, who wants to distribute docker images. It would be operated and managed by the vendor. Only users authorized by the vendor would be able to get write access. Some images would be public (accessible for anyone), others private (accessible only for authorized users). Authentication and authorization would be delegated to the Index. The goal of vendor registries is to let someone do “docker pull basho/riak1.3” and automatically push from the vendor registry (instead of a sponsor registry); i.e. get all the convenience of a sponsor registry, while retaining control on the asset distribution.
 - **private registry**: such a registry is located behind a firewall, or protected by an additional security layer (HTTP authorization, SSL client-side certificates, IP address authorization...). The registry is operated by a private entity, outside of dotCloud’s control. It can optionally delegate additional authorization to the Index, but it is not mandatory.

-.. note::

-    Mirror registries and private registries which do not use the Index don’t even need to run the registry code. They can be implemented by any kind of transport implementing HTTP GET and PUT. Read-only registries can be powered by a simple static HTTP server.

+:description: Managing containerized processes with CFEngine
+:keywords: cfengine, process, management, usage, docker, documentation
+
+Process Management with CFEngine
+================================
+
+Create Docker containers with managed processes.
+
+Docker monitors one process in each running container and the container lives or dies with that process.
+By introducing CFEngine inside Docker containers, we can alleviate a few of the issues that may arise:
+
+* It is possible to easily start multiple processes within a container, all of which will be managed automatically, with the normal ``docker run`` command.
+* If a managed process dies or crashes, CFEngine will start it again within 1 minute.
+* The container itself will live as long as the CFEngine scheduling daemon (cf-execd) lives. With CFEngine, we are able to decouple the life of the container from the uptime of the service it provides.
+
+
+How it works
+------------
+
+CFEngine, together with the cfe-docker integration policies, are installed as part of the Dockerfile. This builds CFEngine into our Docker image.
+
+The Dockerfile's ``ENTRYPOINT`` takes an arbitrary amount of commands (with any desired arguments) as parameters.
+When we run the Docker container these parameters get written to CFEngine policies and CFEngine takes over to ensure that the desired processes are running in the container.
+
+CFEngine scans the process table for the ``basename`` of the commands given to the ``ENTRYPOINT`` and runs the command to start the process if the ``basename`` is not found.
+For example, if we start the container with ``docker run "/path/to/my/application parameters"``, CFEngine will look for a process named ``application`` and run the command.
+If an entry for ``application`` is not found in the process table at any point in time, CFEngine will execute ``/path/to/my/application parameters`` to start the application once again.
+The check on the process table happens every minute.
+
+Note that it is therefore important that the command to start your application leaves a process with the basename of the command.
+This can be made more flexible by making some minor adjustments to the CFEngine policies, if desired.
+
+
+Usage
+-----
+
+This example assumes you have Docker installed and working.
+We will install and manage ``apache2`` and ``sshd`` in a single container.
+
+There are three steps:
+
+1. Install CFEngine into the container.
+2. Copy the CFEngine Docker process management policy into the containerized CFEngine installation.
+3. Start your application processes as part of the ``docker run`` command.
+
+
+Building the container image
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The first two steps can be done as part of a Dockerfile, as follows.
+
+.. code-block:: bash
+
+    FROM ubuntu
+    MAINTAINER Eystein Måløy Stenberg <eytein.stenberg@gmail.com>

+    RUN apt-get -y install wget lsb-release unzip
+

+    RUN echo "deb http://cfengine.com/pub/apt $(lsb_release -cs) main" > /etc/apt/sources.list.d/cfengine-community.list
+    RUN apt-get update
+    RUN apt-get install cfengine-community

+    RUN wget --no-check-certificate https://github.com/estenberg/cfe-docker/archive/master.zip -P /tmp/ && unzip /tmp/master.zip -d /tmp/
+    RUN cp /tmp/cfe-docker-master/cfengine/bin/* /var/cfengine/bin/
+    RUN cp /tmp/cfe-docker-master/cfengine/inputs/* /var/cfengine/inputs/
+    RUN rm -rf /tmp/cfe-docker-master /tmp/master.zip
+
+    # apache2 and openssh are just for testing purposes, install your own apps here
+    RUN apt-get -y install openssh-server apache2
+    RUN mkdir -p /var/run/sshd
+    RUN echo "root:password" | chpasswd  # need a password for ssh
+
+    ENTRYPOINT ["/var/cfengine/bin/docker_processes_run.sh"]
+
+
+By saving this file as ``Dockerfile`` to a working directory, you can then build your container with the docker build command,
+e.g. ``docker build -t managed_image``.
+
+Testing the container
+~~~~~~~~~~~~~~~~~~~~~
+
+Start the container with ``apache2`` and ``sshd`` running and managed, forwarding a port to our SSH instance:
+
+.. code-block:: bash
+
+    docker run -p 127.0.0.1:222:22 -d managed_image "/usr/sbin/sshd" "/etc/init.d/apache2 start"
+
+We now clearly see one of the benefits of the cfe-docker integration: it allows to start several processes
+as part of a normal ``docker run`` command.
+
+We can now log in to our new container and see that both ``apache2`` and ``sshd`` are running. We have set the root password to
+"password" in the Dockerfile above and can use that to log in with ssh:
+
+.. code-block:: bash
+
+    ssh -p222 root@127.0.0.1
+
+    ps -ef
+    UID        PID  PPID  C STIME TTY          TIME CMD
+    root         1     0  0 07:48 ?        00:00:00 /bin/bash /var/cfengine/bin/docker_processes_run.sh /usr/sbin/sshd /etc/init.d/apache2 start
+    root        18     1  0 07:48 ?        00:00:00 /var/cfengine/bin/cf-execd -F
+    root        20     1  0 07:48 ?        00:00:00 /usr/sbin/sshd

+    www-data    34    32  0 07:48 ?        00:00:00 /usr/sbin/apache2 -k start
+    www-data    35    32  0 07:48 ?        00:00:00 /usr/sbin/apache2 -k start
+    www-data    36    32  0 07:48 ?        00:00:00 /usr/sbin/apache2 -k start
+    root        93    20  0 07:48 ?        00:00:00 sshd: root@pts/0 
+    root       105    93  0 07:48 pts/0    00:00:00 -bash
+    root       112   105  0 07:49 pts/0    00:00:00 ps -ef
+
+
+If we stop apache2, it will be started again within a minute by CFEngine.
+
+.. code-block:: bash
+
+    service apache2 status
+     Apache2 is running (pid 32).
+    service apache2 stop

+     Apache2 is NOT running.
+    # ... wait up to 1 minute...
+    service apache2 status
+     Apache2 is running (pid 173).
+
+
+Adapting to your applications
+-----------------------------
+
+To make sure your applications get managed in the same manner, there are just two things you need to adjust from the above example:
+
+* In the Dockerfile used above, install your applications instead of ``apache2`` and ``sshd``.
+* When you start the container with ``docker run``, specify the command line arguments to your applications rather than ``apache2`` and ``sshd``.

+Using Supervisor with Docker
+============================
+
+.. include:: example_header.inc
+
+Traditionally a Docker container runs a single process when it is launched, for
+example an Apache daemon or a SSH server daemon. Often though you want to run
+more than one process in a container. There are a number of ways you can
+achieve this ranging from using a simple Bash script as the value of your
+container's ``CMD`` instruction to installing a process management tool.
+
+In this example we're going to make use of the process management tool,
+`Supervisor <http://supervisord.org/>`_, to manage multiple processes in our
+container. Using Supervisor allows us to better control, manage, and restart the
+processes we want to run. To demonstrate this we're going to install and manage both an
+SSH daemon and an Apache daemon.
+
+Creating a Dockerfile

+    RUN mkdir -p /var/run/sshd
+    RUN mkdir -p /var/log/supervisor
+
+Here we're installing the ``openssh-server``, ``apache2`` and ``supervisor``
+(which provides the Supervisor daemon) packages. We're also creating two new
+directories that are needed to run our SSH daemon and Supervisor.
+
+Adding Supervisor's configuration file
+--------------------------------------
+
+Now let's add a configuration file for Supervisor. The default file is called
+``supervisord.conf`` and is located in ``/etc/supervisor/conf.d/``.
+
+.. code-block:: bash
+
+    ADD supervisord.conf /etc/supervisor/conf.d/supervisord.conf
+
+Let's see what is inside our ``supervisord.conf`` file.
+
+.. code-block:: bash
+
+    [supervisord]
+    nodaemon=true
+
+    [program:sshd]
+    command=/usr/sbin/sshd -D
+
+    [program:apache2]
+    command=/bin/bash -c "source /etc/apache2/envvars && /usr/sbin/apache2 -DFOREGROUND"
+
+The ``supervisord.conf`` configuration file contains directives that configure
+Supervisor and the processes it manages. The first block ``[supervisord]``
+provides configuration for Supervisor itself. We're using one directive,
+``nodaemon`` which tells Supervisor to run interactively rather than daemonize.
+
+The next two blocks manage the services we wish to control. Each block controls
+a separate process. The blocks contain a single directive, ``command``, which
+specifies what command to run to start each process.
+
+Exposing ports and running Supervisor
+-------------------------------------
+
+Now let's finish our ``Dockerfile`` by exposing some required ports and
+specifying the ``CMD`` instruction to start Supervisor when our container
+launches.
+
+.. code-block:: bash
+
+    EXPOSE 22 80
+    CMD ["/usr/bin/supervisord"]
+
+Here we've exposed ports 22 and 80 on the container and we're running the
+``/usr/bin/supervisord`` binary when the container launches.
+
+Building our container
+----------------------
+
+We can now build our new container.
+
+.. code-block:: bash
+
+    sudo docker build -t <yourname>/supervisord .
+
+Running our Supervisor container
+--------------------------------
+
+Once we've got a built image we can launch a container from it.
+
+.. code-block:: bash
+
+    sudo docker run -p 22 -p 80 -t -i <yourname>/supervisor
+    2013-11-25 18:53:22,312 CRIT Supervisor running as root (no user in config file)

+
+Docker Security
+===============
+
+  *Adapted from* `Containers & Docker: How Secure are They? <blogsecurity>`_
+
+There are three major areas to consider when reviewing Docker security:
+
+* the intrinsic security of containers, as implemented by kernel
+  namespaces and cgroups;
+* the attack surface of the Docker daemon itself;
+* the "hardening" security features of the kernel and how they
+  interact with containers.
+
+Kernel Namespaces
+-----------------
+
+Docker containers are essentially LXC containers, and they come with
+the same security features. When you start a container with ``docker
+run``, behind the scenes Docker uses ``lxc-start`` to execute the
+Docker container. This creates a set of namespaces and control groups
+for the container. Those namespaces and control groups are not created
+by Docker itself, but by ``lxc-start``. This means that as the LXC
+userland tools evolve (and provide additional namespaces and isolation
+features), Docker will automatically make use of them.
+
+**Namespaces provide the first and most straightforward form of
+isolation**: processes running within a container cannot see, and even
+less affect, processes running in another container, or in the host
+system.
+
+**Each container also gets its own network stack**, meaning that a
+container doesn’t get a privileged access to the sockets or interfaces
+of another container. Of course, if the host system is setup
+accordingly, containers can interact with each other through their
+respective network interfaces — just like they can interact with
+external hosts. When you specify public ports for your containers or
+use :ref:`links <working_with_links_names>` then IP traffic is allowed
+between containers. They can ping each other, send/receive UDP
+packets, and establish TCP connections, but that can be restricted if
+necessary. From a network architecture point of view, all containers
+on a given Docker host are sitting on bridge interfaces. This means
+that they are just like physical machines connected through a common
+Ethernet switch; no more, no less.
+
+How mature is the code providing kernel namespaces and private
+networking?  Kernel namespaces were introduced `between kernel version
+2.6.15 and 2.6.26
+<http://lxc.sourceforge.net/index.php/about/kernel-namespaces/>`_. This
+means that since July 2008 (date of the 2.6.26 release, now 5 years
+ago), namespace code has been exercised and scrutinized on a large
+number of production systems. And there is more: the design and
+inspiration for the namespaces code are even older. Namespaces are
+actually an effort to reimplement the features of `OpenVZ
+<http://en.wikipedia.org/wiki/OpenVZ>`_ in such a way that they could
+be merged within the mainstream kernel. And OpenVZ was initially
+released in 2005, so both the design and the implementation are
+pretty mature.

+Control Groups are the other key component of Linux Containers. They
+implement resource accounting and limiting. They provide a lot of very
+useful metrics, but they also help to ensure that each container gets
+its fair share of memory, CPU, disk I/O; and, more importantly, that a
+single container cannot bring the system down by exhausting one of
+those resources.
+
+So while they do not play a role in preventing one container from
+accessing or affecting the data and processes of another container,
+they are essential to fend off some denial-of-service attacks. They
+are particularly important on multi-tenant platforms, like public and
+private PaaS, to guarantee a consistent uptime (and performance) even
+when some applications start to misbehave.
+
+Control Groups have been around for a while as well: the code was
+started in 2006, and initially merged in kernel 2.6.24.
+
+Docker Daemon Attack Surface
+----------------------------
+
+Running containers (and applications) with Docker implies running the
+Docker daemon. This daemon currently requires root privileges, and you
+should therefore be aware of some important details.
+
+First of all, **only trusted users should be allowed to control your
+Docker daemon**. This is a direct consequence of some powerful Docker
+features. Specifically, Docker allows you to share a directory between
+the Docker host and a guest container; and it allows you to do so
+without limiting the access rights of the container. This means that
+you can start a container where the ``/host`` directory will be the
+``/`` directory on your host; and the container will be able to alter
+your host filesystem without any restriction. This sounds crazy? Well,
+you have to know that **all virtualization systems allowing filesystem
+resource sharing behave the same way**. Nothing prevents you from
+sharing your root filesystem (or even your root block device) with a
+virtual machine.
+
+This has a strong security implication: if you instrument Docker from
+e.g. a web server to provision containers through an API, you should
+be even more careful than usual with parameter checking, to make sure
+that a malicious user cannot pass crafted parameters causing Docker to
+create arbitrary containers.
+
+For this reason, the REST API endpoint (used by the Docker CLI to
+communicate with the Docker daemon) changed in Docker 0.5.2, and now
+uses a UNIX socket instead of a TCP socket bound on 127.0.0.1 (the
+latter being prone to cross-site-scripting attacks if you happen to
+run Docker directly on your local machine, outside of a VM). You can
+then use traditional UNIX permission checks to limit access to the
+control socket.
+
+You can also expose the REST API over HTTP if you explicitly decide
+so. However, if you do that, being aware of the abovementioned
+security implication, you should ensure that it will be reachable
+only from a trusted network or VPN; or protected with e.g. ``stunnel``
+and client SSL certificates.
+
+Recent improvements in Linux namespaces will soon allow to run
+full-featured containers without root privileges, thanks to the new
+user namespace. This is covered in detail `here
+<http://s3hh.wordpress.com/2013/07/19/creating-and-using-containers-without-privilege/>`_. Moreover,
+this will solve the problem caused by sharing filesystems between host
+and guest, since the user namespace allows users within containers
+(including the root user) to be mapped to other users in the host
+system.
+
+The end goal for Docker is therefore to implement two additional
+security improvements:
+
+* map the root user of a container to a non-root user of the Docker
+  host, to mitigate the effects of a container-to-host privilege
+  escalation;
+* allow the Docker daemon to run without root privileges, and delegate
+  operations requiring those privileges to well-audited sub-processes,
+  each with its own (very limited) scope: virtual network setup,
+  filesystem management, etc.
+
+Finally, if you run Docker on a server, it is recommended to run
+exclusively Docker in the server, and move all other services within
+containers controlled by Docker. Of course, it is fine to keep your
+favorite admin tools (probably at least an SSH server), as well as
+existing monitoring/supervision processes (e.g. NRPE, collectd, etc).
+
+Linux Kernel Capabilities
+-------------------------
+
+By default, Docker starts containers with a very restricted set of
+capabilities. What does that mean?
+
+Capabilities turn the binary "root/non-root" dichotomy into a
+fine-grained access control system. Processes (like web servers) that
+just need to bind on a port below 1024 do not have to run as root:
+they can just be granted the ``net_bind_service`` capability
+instead. And there are many other capabilities, for almost all the
+specific areas where root privileges are usually needed.
+
+This means a lot for container security; let’s see why!
+
+Your average server (bare metal or virtual machine) needs to run a
+bunch of processes as root. Those typically include SSH, cron,
+syslogd; hardware management tools (to e.g. load modules), network
+configuration tools (to handle e.g. DHCP, WPA, or VPNs), and much
+more. A container is very different, because almost all of those tasks
+are handled by the infrastructure around the container:
+
+* SSH access will typically be managed by a single server running in
+  the Docker host;
+* ``cron``, when necessary, should run as a user process, dedicated
+  and tailored for the app that needs its scheduling service, rather
+  than as a platform-wide facility;
+* log management will also typically be handed to Docker, or by
+  third-party services like Loggly or Splunk;
+* hardware management is irrelevant, meaning that you never need to
+  run ``udevd`` or equivalent daemons within containers;
+* network management happens outside of the containers, enforcing
+  separation of concerns as much as possible, meaning that a container
+  should never need to perform ``ifconfig``, ``route``, or ip commands
+  (except when a container is specifically engineered to behave like a
+  router or firewall, of course).
+
+This means that in most cases, containers will not need "real" root
+privileges *at all*. And therefore, containers can run with a reduced
+capability set; meaning that "root" within a container has much less
+privileges than the real "root". For instance, it is possible to:
+
+* deny all "mount" operations;
+* deny access to raw sockets (to prevent packet spoofing);
+* deny access to some filesystem operations, like creating new device
+  nodes, changing the owner of files, or altering attributes
+  (including the immutable flag);
+* deny module loading;
+* and many others.
+
+This means that even if an intruder manages to escalate to root within
+a container, it will be much harder to do serious damage, or to
+escalate to the host.
+
+This won't affect regular web apps; but malicious users will find that
+the arsenal at their disposal has shrunk considerably! You can see
+`the list of dropped capabilities in the Docker code
+<https://github.com/dotcloud/docker/blob/v0.5.0/lxc_template.go#L97>`_,
+and a full list of available capabilities in `Linux manpages
+<http://man7.org/linux/man-pages/man7/capabilities.7.html>`_.
+
+Of course, you can always enable extra capabilities if you really need
+them (for instance, if you want to use a FUSE-based filesystem), but
+by default, Docker containers will be locked down to ensure maximum
+safety.
+
+Other Kernel Security Features
+------------------------------
+
+Capabilities are just one of the many security features provided by
+modern Linux kernels. It is also possible to leverage existing,
+well-known systems like TOMOYO, AppArmor, SELinux, GRSEC, etc. with
+Docker.
+
+While Docker currently only enables capabilities, it doesn't interfere
+with the other systems. This means that there are many different ways
+to harden a Docker host. Here are a few examples.
+
+* You can run a kernel with GRSEC and PAX. This will add many safety
+  checks, both at compile-time and run-time; it will also defeat many
+  exploits, thanks to techniques like address randomization. It
+  doesn’t require Docker-specific configuration, since those security
+  features apply system-wide, independently of containers.
+* If your distribution comes with security model templates for LXC
+  containers, you can use them out of the box. For instance, Ubuntu
+  comes with AppArmor templates for LXC, and those templates provide
+  an extra safety net (even though it overlaps greatly with
+  capabilities).
+* You can define your own policies using your favorite access control
+  mechanism. Since Docker containers are standard LXC containers,
+  there is nothing “magic” or specific to Docker.
+
+Just like there are many third-party tools to augment Docker
+containers with e.g. special network topologies or shared filesystems,
+you can expect to see tools to harden existing Docker containers
+without affecting Docker’s core.
+
+Conclusions
+-----------
+
+Docker containers are, by default, quite secure; especially if you
+take care of running your processes inside the containers as
+non-privileged users (i.e. non root).
+
+You can add an extra layer of safety by enabling Apparmor, SELinux,
+GRSEC, or your favorite hardening solution.
+
+Last but not least, if you see interesting security features in other
+containerization systems, you will be able to implement them as well
+with Docker, since everything is provided by the kernel anyway.
+

+container systems, please also see the `original blog post

+:keywords: Examples, Usage, links, docker, documentation, examples, names, name, container naming
+
+.. _ambassador_pattern_linking:
+
+Link via an Ambassador Container
+================================
+
+Rather than hardcoding network links between a service consumer and provider, Docker
+encourages service portability.
+
+eg, instead of
+
+.. code-block:: bash
+
+	(consumer) --> (redis)
+
+requiring you to restart the ``consumer`` to attach it to a different ``redis`` service, 
+you can add ambassadors
+
+.. code-block:: bash
+
+	(consumer) --> (redis-ambassador) --> (redis)
+
+	or
+
+	(consumer) --> (redis-ambassador) ---network---> (redis-ambassador) --> (redis)
+
+When you need to rewire your consumer to talk to a different redis server, you 
+can just restart the ``redis-ambassador`` container that the consumer is connected to.
+
+This pattern also allows you to transparently move the redis server to a different
+docker host from the consumer.
+
+Using the ``svendowideit/ambassador`` container, the link wiring is controlled entirely 
+from the ``docker run`` parameters.
+
+Two host Example
+----------------
+
+Start actual redis server on one Docker host
+
+.. code-block:: bash
+
+	big-server $ docker run -d -name redis crosbymichael/redis
+
+Then add an ambassador linked to the redis server, mapping a port to the outside world
+
+.. code-block:: bash
+
+	big-server $ docker run -d -link redis:redis -name redis_ambassador -p 6379:6379 svendowideit/ambassador
+
+On the other host, you can set up another ambassador setting environment variables for each remote port we want to proxy to the ``big-server``
+
+.. code-block:: bash
+
+	client-server $ docker run -d -name redis_ambassador -expose 6379 -e REDIS_PORT_6379_TCP=tcp://192.168.1.52:6379 svendowideit/ambassador
+
+Then on the ``client-server`` host, you can use a redis client container to talk 
+to the remote redis server, just by linking to the local redis ambassador.
+
+.. code-block:: bash
+
+	client-server $ docker run -i -t -rm -link redis_ambassador:redis relateiq/redis-cli
+	redis 172.17.0.160:6379> ping
+	PONG
+
+
+
+How it works
+------------
+
+The following example shows what the ``svendowideit/ambassador`` container does 
+automatically (with a tiny amount of ``sed``)
+
+On the docker host (192.168.1.52) that redis will run on:
+
+.. code-block:: bash
+
+	# start actual redis server
+	$ docker run -d -name redis crosbymichael/redis
+
+	# get a redis-cli container for connection testing	
+	$ docker pull relateiq/redis-cli
+
+	# test the redis server by talking to it directly
+	$ docker run -t -i -rm -link redis:redis relateiq/redis-cli
+	redis 172.17.0.136:6379> ping
+	PONG
+	^D
+	
+	# add redis ambassador
+	$ docker run -t -i -link redis:redis -name redis_ambassador -p 6379:6379 busybox sh
+	
+in the redis_ambassador container, you can see the linked redis containers's env
+
+.. code-block:: bash
+
+	$ env
+	REDIS_PORT=tcp://172.17.0.136:6379
+	REDIS_PORT_6379_TCP_ADDR=172.17.0.136
+	REDIS_NAME=/redis_ambassador/redis
+	HOSTNAME=19d7adf4705e
+	REDIS_PORT_6379_TCP_PORT=6379
+	HOME=/
+	REDIS_PORT_6379_TCP_PROTO=tcp
+	container=lxc
+	REDIS_PORT_6379_TCP=tcp://172.17.0.136:6379
+	TERM=xterm
+	PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
+	PWD=/
+	
+	
+This environment is used by the ambassador socat script to expose redis to the world 
+(via the -p 6379:6379 port mapping)
+
+.. code-block:: bash
+
+	$ docker rm redis_ambassador
+	$ sudo ./contrib/mkimage-unittest.sh
+	$ docker run -t -i -link redis:redis -name redis_ambassador -p 6379:6379 docker-ut sh
+	
+	$ socat TCP4-LISTEN:6379,fork,reuseaddr TCP4:172.17.0.136:6379
+	
+then ping the redis server via the ambassador
+
+.. code-block::bash
+
+	$ docker run -i -t -rm -link redis_ambassador:redis relateiq/redis-cli
+	redis 172.17.0.160:6379> ping
+	PONG
+
+Now goto a different server
+
+.. code-block:: bash
+
+	$ sudo ./contrib/mkimage-unittest.sh
+	$ docker run -t -i  -expose 6379 -name redis_ambassador docker-ut sh
+	
+	$ socat TCP4-LISTEN:6379,fork,reuseaddr TCP4:192.168.1.52:6379
+
+and get the redis-cli image so we can talk over the ambassador bridge
+
+.. code-block:: bash
+
+	$ docker pull relateiq/redis-cli
+	$ docker run -i -t -rm -link redis_ambassador:redis relateiq/redis-cli
+	redis 172.17.0.160:6379> ping
+	PONG
+
+The svendowideit/ambassador Dockerfile
+--------------------------------------
+
+The ``svendowideit/ambassador`` image is a small busybox image with ``socat`` built in.
+When you start the container, it uses a small ``sed`` script to parse out the (possibly multiple)
+link environment variables to set up the port forwarding. On the remote host, you need to set the 
+variable using the ``-e`` command line option.
+
+``-expose 1234 -e REDIS_PORT_1234_TCP=tcp://192.168.1.52:6379`` will forward the 
+local ``1234`` port to the remote IP and port - in this case ``192.168.1.52:6379``.
+
+
+::
+
+	#
+	#

+	# on the remote host, you can set up another ambassador

+
+Configure Networking
+====================
+
+Docker uses Linux bridge capabilities to provide network connectivity
+to containers. The ``docker0`` bridge interface is managed by Docker
+itself for this purpose. Thus, when the Docker daemon starts it :
+
+- creates the ``docker0`` bridge if not present
+- searches for an IP address range which doesn't overlap with an existing route
+- picks an IP in the selected range
+- assigns this IP to the ``docker0`` bridge
+
+
+.. code-block:: bash
+    
+    # List host bridges
+    $ sudo brctl show
+    bridge	name	bridge id		STP enabled	interfaces
+    docker0		8000.000000000000	no	
+
+    # Show docker0 IP address
+    $ sudo ifconfig docker0
+    docker0   Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
+   	 inet addr:172.17.42.1  Bcast:0.0.0.0  Mask:255.255.0.0
+
+
+
+At runtime, a :ref:`specific kind of virtual
+interface<vethxxxx-device>` is given to each containers which is then
+bonded to the ``docker0`` bridge.  Each containers also receives a
+dedicated IP address from the same range as ``docker0``. The
+``docker0`` IP address is then used as the default gateway for the
+containers.
+
+.. code-block:: bash
+
+    # Run a container
+    $ sudo docker run -t -i -d base /bin/bash
+    52f811c5d3d69edddefc75aff5a4525fc8ba8bcfa1818132f9dc7d4f7c7e78b4
+
+    $ sudo brctl show
+    bridge	name	bridge id		STP enabled	interfaces
+    docker0		8000.fef213db5a66	no		vethQCDY1N
+
+
+Above, ``docker0`` acts as a bridge for the ``vethQCDY1N`` interface
+which is dedicated to the 52f811c5d3d6 container.
+
+
+How to use a specific IP address range
+---------------------------------------
+
+Docker will try hard to find an IP range which is not used by the
+host.  Even if it works for most cases, it's not bullet-proof and
+sometimes you need to have more control over the IP addressing scheme.
+
+For this purpose, Docker allows you to manage the ``docker0`` bridge
+or your own one using the ``-b=<bridgename>`` parameter.
+
+In this scenario:
+
+- ensure Docker is stopped
+- create your own bridge (``bridge0`` for example)
+- assign a specific IP to this bridge
+- start Docker with the ``-b=bridge0`` parameter
+
+
+.. code-block:: bash
+
+    # Stop Docker
+    $ sudo service docker stop
+
+    # Clean docker0 bridge and
+    # add your very own bridge0
+    $ sudo ifconfig docker0 down
+    $ sudo brctl addbr bridge0

+- The default, ``-icc=true`` allows containers to communicate with each other.

+Trusted Builds
+--------------
+
+Trusted Builds automate the building and updating of images from GitHub, directly 
+on docker.io servers. It works by adding a commit hook to your selected repository,
+triggering a build and update when you push a commit.
+
+To setup a trusted build
++++++++++++++++++++++++
+
+#. Create a `Docker Index account <https://index.docker.io/>`_ and login.
+#. Link your GitHub account through the ``Link Accounts`` menu.
+#. `Configure a Trusted build <https://index.docker.io/builds/>`_.
+#. Pick a GitHub project that has a ``Dockerfile`` that you want to build.
+#. Pick the branch you want to build (the default is the  ``master`` branch).
+#. Give the Trusted Build a name.
+#. Assign an optional Docker tag to the Build.
+#. Specify where the ``Dockerfile`` is located. The default is ``/``.
+
+Once the Trusted Build is configured it will automatically trigger a build, and
+in a few minutes, if there are no errors, you will see your new trusted build
+on the Docker Index. It will will stay in sync with your GitHub repo until you
+deactivate the Trusted Build.
+
+If you want to see the status of your Trusted Builds you can go to your
+`Trusted Builds page <https://index.docker.io/builds/>`_ on the Docker index,
+and it will show you the status of your builds, and the build history.
+
+Once you've created a Trusted Build you can deactive or delete it. You cannot
+however push to a Trusted Build with the ``docker push`` command. You can only
+manage it by committing code to your GitHub repository.
+
+You can create multiple Trusted Builds per repository and configure them to
+point to specific ``Dockerfile``'s or Git branches.
