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 ` 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 +`_. 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 +`_ 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 +-------------- + +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 +`_. 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 +`_, +and a full list of available capabilities in `Linux manpages +`_. + +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. + +For more context and especially for comparisons with VMs and other +container systems, please also see the `original blog post +`_. + +.. _blogsecurity: http://blog.docker.io/2013/08/containers-docker-how-secure-are-they/ + diff --git a/docs/sources/use/workingwithrepository.rst b/docs/sources/use/workingwithrepository.rst index 66b2928c96..5faebcc2e5 100644 --- a/docs/sources/use/workingwithrepository.rst +++ b/docs/sources/use/workingwithrepository.rst @@ -177,6 +177,15 @@ you can push and pull it like any other repository, but it will there will be no user name checking performed.
