<p>Docker is 100% free. It is open source, so you can use it without paying.</p>
|
|
|
|
<h3 id="what-open-source-license-are-you-using">What open source license are you using?</h3>
|
|
|
|
<p>We are using the Apache License Version 2.0, see it here:

|
|
|
|
<p>Docker currently runs only on Linux, but you can use VirtualBox to run Docker in
|
|
a virtual machine on your box, and get the best of both worlds. Check out the
|
|
<a href="../../../engine/installation/mac/"><em>Mac OS X</em></a> and <a href="../../../engine/installation/windows/"><em>Microsoft
|
|
Windows</em></a> installation guides. The small Linux
|
|
distribution Docker Machine can be run inside virtual machines on these two
|
|
operating systems.</p>
|
|
|
|
<blockquote>
|
|
<p><strong>Note:</strong> if you are using a remote Docker daemon on a VM through Docker
|
|
Machine, then <em>do not</em> type the <code>sudo</code> before the <code>docker</code> commands shown in
|
|
the documentation’s examples.</p>

|
<h3 id="how-do-containers-compare-to-virtual-machines">How do containers compare to virtual machines?</h3>
|
|
|
|
<p>They are complementary. VMs are best used to allocate chunks of hardware
|
|
resources. Containers operate at the process level, which makes them very
|
|
lightweight and perfect as a unit of software delivery.</p>
|
|
|
|
<h3 id="what-does-docker-add-to-just-plain-lxc">What does Docker add to just plain LXC?</h3>
|
|
|
|
<p>Docker is not a replacement for LXC. “LXC” refers to capabilities of the Linux
|
|
kernel (specifically namespaces and control groups) which allow sandboxing
|
|
processes from one another, and controlling their resource allocations. On top
|
|
of this low-level foundation of kernel features, Docker offers a high-level tool
|
|
with several powerful functionalities:</p>
|
|
|
|
<ul>
|
|
<li><p><em>Portable deployment across machines.</em> Docker defines a format for bundling
|
|
an application and all its dependencies into a single object which can be
|
|
transferred to any Docker-enabled machine, and executed there with the
|
|
guarantee that the execution environment exposed to the application will be the
|
|
same. LXC implements process sandboxing, which is an important pre-requisite
|
|
for portable deployment, but that alone is not enough for portable deployment.
|
|
If you sent me a copy of your application installed in a custom LXC
|
|
configuration, it would almost certainly not run on my machine the way it does
|
|
on yours, because it is tied to your machine’s specific configuration:
|
|
networking, storage, logging, distro, etc. Docker defines an abstraction for
|
|
these machine-specific settings, so that the exact same Docker container can
|
|
run - unchanged - on many different machines, with many different
|
|
configurations.</p></li>
|
|
|
|
<li><p><em>Application-centric.</em> Docker is optimized for the deployment of
|
|
applications, as opposed to machines. This is reflected in its API, user
|
|
interface, design philosophy and documentation. By contrast, the <code>lxc</code> helper
|
|
scripts focus on containers as lightweight machines - basically servers that
|
|
boot faster and need less RAM. We think there’s more to containers than just
|
|
that.</p></li>
|
|
|
|
<li><p><em>Automatic build.</em> Docker includes <a href="../../../engine/reference/builder/"><em>a tool for developers to automatically
|
|
assemble a container from their source
|
|
code</em></a>, with full control over application
|
|
dependencies, build tools, packaging etc. They are free to use <code>make</code>, <code>maven</code>,
|
|
<code>chef</code>, <code>puppet</code>, <code>salt,</code> Debian packages, RPMs, source tarballs, or any
|
|
combination of the above, regardless of the configuration of the machines.</p></li>
|
|
|
|
<li><p><em>Versioning.</em> Docker includes git-like capabilities for tracking successive
|
|
versions of a container, inspecting the diff between versions, committing new
|
|
versions, rolling back etc. The history also includes how a container was
|
|
assembled and by whom, so you get full traceability from the production server
|
|
all the way back to the upstream developer. Docker also implements incremental
|
|
uploads and downloads, similar to <code>git pull</code>, so new versions of a container
|
|
can be transferred by only sending diffs.</p></li>
|
|
|
|
<li><p><em>Component re-use.</em> Any container can be used as a <a href="../../../engine/reference/glossary/#image"><em>“base image”</em></a> to create more specialized components. This can
|
|
be done manually or as part of an automated build. For example you can prepare
|
|
the ideal Python environment, and use it as a base for 10 different
|
|
applications. Your ideal PostgreSQL setup can be re-used for all your future
|
|
projects. And so on.</p></li>
|
|
|
|
<li><p><em>Sharing.</em> Docker has access to a public registry <a href="https://hub.docker.com/">on Docker Hub</a>
|
|
where thousands of people have uploaded useful images: anything from Redis,
|
|
CouchDB, PostgreSQL to IRC bouncers to Rails app servers to Hadoop to base
|
|
images for various Linux distros. The
|
|
<a href="https://docs.docker.com/registry/"><em>registry</em></a> also
|
|
includes an official “standard library” of useful containers maintained by the
|
|
Docker team. The registry itself is open-source, so anyone can deploy their own
|
|
registry to store and transfer private containers, for internal server
|
|
deployments for example.</p></li>
|
|
|
|
<li><p><em>Tool ecosystem.</em> Docker defines an API for automating and customizing the
|
|
creation and deployment of containers. There are a huge number of tools
|
|
integrating with Docker to extend its capabilities. PaaS-like deployment
|
|
(Dokku, Deis, Flynn), multi-node orchestration (Maestro, Salt, Mesos, Openstack
|
|
Nova), management dashboards (docker-ui, Openstack Horizon, Shipyard),
|
|
configuration management (Chef, Puppet), continuous integration (Jenkins,
|
|
Strider, Travis), etc. Docker is rapidly establishing itself as the standard
|
|
for container-based tooling.</p></li>

<h3 id="what-is-different-between-a-docker-container-and-a-vm">What is different between a Docker container and a VM?</h3>
|
|
|
|
<p>There’s a great StackOverflow answer <a href="http://stackoverflow.com/questions/16047306/how-is-docker-io-different-from-a-normal-virtual-machine">showing the differences</a>.</p>
|
|
|
|
<h3 id="do-i-lose-my-data-when-the-container-exits">Do I lose my data when the container exits?</h3>
|
|
|
|
<p>Not at all! Any data that your application writes to disk gets preserved in its
|
|
container until you explicitly delete the container. The file system for the
|
|
container persists even after the container halts.</p>
|
|
|
|
<h3 id="how-far-do-docker-containers-scale">How far do Docker containers scale?</h3>
|
|
|
|
<p>Some of the largest server farms in the world today are based on containers.
|
|
Large web deployments like Google and Twitter, and platform providers such as
|
|
Heroku and dotCloud all run on container technology, at a scale of hundreds of
|
|
thousands or even millions of containers running in parallel.</p>
|
|
|
|
<h3 id="how-do-i-connect-docker-containers">How do I connect Docker containers?</h3>
|
|
|
|
<p>Currently the recommended way to connect containers is via the Docker network feature. You can see details of how to <a href="https://docs.docker.com/networking">work with Docker networks here</a>.</p>
|
|
|
|
<p>Also useful for more flexible service portability is the <a href="../../../engine/articles/ambassador_pattern_linking/">Ambassador linking
|
|
pattern</a>.</p>
|
|
|
|
<h3 id="how-do-i-run-more-than-one-process-in-a-docker-container">How do I run more than one process in a Docker container?</h3>
|
|
|
|
<p>Any capable process supervisor such as <a href="http://supervisord.org/">http://supervisord.org/</a>, runit, s6, or daemontools can do the trick. Docker
|
|
will start up the process management daemon which will then fork to run
|
|
additional processes. As long as the processor manager daemon continues to run,
|
|
the container will continue to as well. You can see a more substantial example
|
|
<a href="../../../engine/articles/using_supervisord/">that uses supervisord here</a>.</p>

<h3 id="when-building-an-image-should-i-prefer-system-libraries-or-bundled-ones">When building an image, should I prefer system libraries or bundled ones?</h3>
|
|
|
|
<p><em>This is a summary of a discussion on the <a href="https://groups.google.com/forum/#!topic/docker-dev/L2RBSPDu1L0">docker-dev mailing list</a>.</em></p>
|
|
|
|
<p>Virtually all programs depend on third-party libraries. Most frequently, they
|
|
will use dynamic linking and some kind of package dependency, so that when
|
|
multiple programs need the same library, it is installed only once.</p>
|
|
|
|
<p>Some programs, however, will bundle their third-party libraries, because they
|
|
rely on very specific versions of those libraries. For instance, Node.js bundles
|
|
OpenSSL; MongoDB bundles V8 and Boost (among others).</p>
|
|
|
|
<p>When creating a Docker image, is it better to use the bundled libraries, or
|
|
should you build those programs so that they use the default system libraries
|
|
instead?</p>
|
|
|
|
<p>The key point about system libraries is not about saving disk or memory space.
|
|
It is about security. All major distributions handle security seriously, by
|
|
having dedicated security teams, following up closely with published
|
|
vulnerabilities, and disclosing advisories themselves. (Look at the <a href="https://www.debian.org/security/">Debian
|
|
Security Information</a> for an example of those
|
|
procedures.) Upstream developers, however, do not always implement similar
|
|
practices.</p>
|
|
|
|
<p>Before setting up a Docker image to compile a program from source, if you want
|
|
to use bundled libraries, you should check if the upstream authors provide a
|
|
convenient way to announce security vulnerabilities, and if they update their
|
|
bundled libraries in a timely manner. If they don’t, you are exposing yourself
|
|
(and the users of your image) to security vulnerabilities.</p>
|
|
|
|
<p>Likewise, before using packages built by others, you should check if the
|
|
channels providing those packages implement similar security best practices.
|
|
Downloading and installing an “all-in-one” .deb or .rpm sounds great at first,
|
|
except if you have no way to figure out that it contains a copy of the OpenSSL
|
|
library vulnerable to the <a href="http://heartbleed.com/">Heartbleed</a> bug.</p>
|
|
|
|
<h3 id="why-is-debian-frontend-noninteractive-discouraged-in-dockerfiles">Why is <code>DEBIAN_FRONTEND=noninteractive</code> discouraged in Dockerfiles?</h3>
|
|
|
|
<p>When building Docker images on Debian and Ubuntu you may have seen errors like:</p>
|
|
|
|
<pre><code>unable to initialize frontend: Dialog
|
|
</code></pre>
|
|
|
|
<p>These errors don’t stop the image from being built but inform you that the
|
|
installation process tried to open a dialog box, but was unable to. Generally,
|
|
these errors are safe to ignore.</p>
|
|
|
|
<p>Some people circumvent these errors by changing the <code>DEBIAN_FRONTEND</code>
|
|
environment variable inside the Dockerfile using:</p>
|
|
|
|
<pre><code>ENV DEBIAN_FRONTEND=noninteractive
|
|
</code></pre>
|
|
|
|
<p>This prevents the installer from opening dialog boxes during installation which
|
|
stops the errors.</p>
|
|
|
|
<p>While this may sound like a good idea, it <em>may</em> have side effects. The
|
|
<code>DEBIAN_FRONTEND</code> environment variable will be inherited by all images and
|
|
containers built from your image, effectively changing their behavior. People
|
|
using those images will run into problems when installing software
|
|
interactively, because installers will not show any dialog boxes.</p>
|
|
|
|
<p>Because of this, and because setting <code>DEBIAN_FRONTEND</code> to <code>noninteractive</code> is
|
|
mainly a ‘cosmetic’ change, we <em>discourage</em> changing it.</p>
|
|
|
|
<p>If you <em>really</em> need to change its setting, make sure to change it back to its
|
|
<a href="https://www.debian.org/releases/stable/i386/ch05s03.html.en">default value</a>
|
|
afterwards.</p>

<h3 id="why-do-i-get-connection-reset-by-peer-when-making-a-request-to-a-service-running-in-a-container">Why do I get <code>Connection reset by peer</code> when making a request to a service running in a container?</h3>
|
|
|
|
<p>Typically, this message is returned if the service is already bound to your
|
|
localhost. As a result, requests coming to the container from outside are
|
|
dropped. To correct this problem, change the service’s configuration on your
|
|
localhost so that the service accepts requests from all IPs. If you aren’t sure
|
|
how to do this, check the documentation for your OS.</p>
