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.
|

</p>
|
||
|
||
<p>
|
||
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.

<h4>Heterogeneous payloads</h4>
|
||
<p>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.</p>

<h4>Any server</h4>
|
||
<p>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.</p>

<h4>Isolation</h4>

<h2>Notable features</h2>
|
||
|
||
<ul>
|
||
<li>Filesystem isolation: each process container runs in a completely separate root filesystem.</li>
|
||
<li>Resource isolation: system resources like cpu and memory can be allocated differently to each process container, using cgroups.</li>
|
||
<li>Network isolation: each process container runs in its own network namespace, with a virtual interface and IP address of its own.</li>
|
||
<li>Copy-on-write: root filesystems are created using copy-on-write, which makes deployment extremeley fast, memory-cheap and disk-cheap.</li>
|
||
<li>Logging: the standard streams (stdout/stderr/stdin) of each process container is collected and logged for real-time or batch retrieval.</li>
|
||
<li>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.</li>
|
||
<li>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.</li>
|
||
</ul>
|
||
|
||
<h2>Under the hood</h2>
|
||
|
||
<p>Under the hood, Docker is built on the following components:</p>
|
||
|
||
<ul>
|
||
<li>The <a href="http://blog.dotcloud.com/kernel-secrets-from-the-paas-garage-part-24-c">cgroup</a> and <a href="http://blog.dotcloud.com/under-the-hood-linux-kernels-on-dotcloud-part">namespacing</a> capabilities of the Linux kernel;</li>
|
||
<li><a href="http://aufs.sourceforge.net/aufs.html">AUFS</a>, a powerful union filesystem with copy-on-write capabilities;</li>
|
||
<li>The <a href="http://golang.org">Go</a> programming language;</li>
|
||
<li><a href="http://lxc.sourceforge.net/">lxc</a>, a set of convenience scripts to simplify the creation of linux containers.</li>
