- <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>
|
|
|
- <p>Docker isolates processes from each other and from the underlying host, using lightweight containers.</p>
|
|
|
- <h4>Repeatability</h4>
|
|
|
- <p>Because each container is isolated in its own filesystem, they behave the same regardless of where, when, and alongside what they run.</p>

- <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 extremely 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>
|
|
|
- </ul>
|
|
|
-
|
|
|
- <h2>Who started it</h2>
|
|
|
- <p>
|
|
|
- Docker is an open-source implementation of the deployment engine which powers <a href="http://dotcloud.com">dotCloud</a>, a popular Platform-as-a-Service.</p>
|
|
|
-
|
|
|
- <p>It benefits directly from the experience accumulated over several years of large-scale operation and support of hundreds of thousands
|
|
|
- of applications and databases.
