<h1 id="build-your-own-image">Build your own image</h1>
<p>The <code>whalesay</code> image could be improved. It would be nice if you didn&rsquo;t have to
think of something to say. And you type a lot to get <code>whalesay</code> to talk.</p>
<pre><code>docker run docker/whalesay cowsay boo-boo
</code></pre>
<p>In this next section, you will improve the <code>whalesay</code> image by building a new version that &ldquo;talks on its own&rdquo; and requires fewer words to run.</p>
<h2 id="step-1-write-a-dockerfile">Step 1: Write a Dockerfile</h2>
<p>In this step, you use your favorite text editor to write a short Dockerfile. A
Dockerfile describes the software that is &ldquo;baked&rdquo; into an image. It isn&rsquo;t just
ingredients tho, it can tell the software what environment to use or what
commands to run. Your recipe is going to be very short.</p>
<ol>
<li><p>Go back to your terminal window.</p></li>
<li><p>Make a new directory by typing <code>mkdir mydockerbuild</code> and pressing RETURN.</p>
<pre><code>$ mkdir mydockerbuild
</code></pre>
<p>This directory serves as the &ldquo;context&rdquo; for your build. The context just means it contains all the things you need to build your image.</p></li>
<li><p>Change to your new directory.</p>
<pre><code>$ cd mydockerbuild
</code></pre>
<p>Right now the directory is empty.</p></li>
<li><p>Create a text file called <code>Dockerfile</code> in your current directory.</p>
<p>You can use any text editor for example, <code>vi</code> or <code>nano</code> to do this.</p></li>
<li><p>Open your Dockerfile file.</p></li>
<li><p>Add a line to the file like this:</p>
<pre><code>FROM docker/whalesay:latest
</code></pre>
<p>The <code>FROM</code> keyword tells Docker which image your image is based on. Whalesay is
cute and has the <code>cowsay</code> program already, so we&rsquo;ll start there.</p></li>
<li><p>Now, add the <code>fortunes</code> program to the image.</p>
<pre><code>RUN apt-get -y update &amp;&amp; apt-get install -y fortunes
</code></pre>
<p>The <code>fortunes</code> program has a command that prints out wise sayings for our
whale to say. So, the first step is to install it. This line installs the
software into the image.</p></li>
<li><p>Once the image has the software it needs, you instruct the software to run
when the image is loaded.</p>
<pre><code>CMD /usr/games/fortune -a | cowsay
</code></pre>
<p>This line tells the <code>fortune</code> program to pass a nifty quote to the <code>cowsay</code> program.</p></li>
<li><p>Check your work, your file should look like this:</p>
<pre><code>FROM docker/whalesay:latest
RUN apt-get -y update &amp;&amp; apt-get install -y fortunes
CMD /usr/games/fortune -a | cowsay
</code></pre></li>
<li><p>Save and close your Dockerfile.</p>
<p>At this point, you have all your software ingredients and behaviors described in a Dockerfile. You are ready to build a new image.</p></li>
</ol>
<h2 id="step-2-build-an-image-from-your-dockerfile">Step 2: Build an image from your Dockerfile</h2>
<ol>
<li><p>Now, build your new image by typing the <code>docker build -t docker-whale .</code> command in your terminal (don&rsquo;t forget the . period).</p>
<pre><code>$ docker build -t docker-whale .
Sending build context to Docker daemon 158.8 MB
...snip...
Removing intermediate container a8e6faa88df3
Successfully built 7d9495d03763
</code></pre>
<p>The command takes several seconds to run and reports its outcome. Before
you do anything with the new image, take a minute to learn about the
Dockerfile build process.</p></li>
</ol>
<h2 id="step-3-learn-about-the-build-process">Step 3: Learn about the build process</h2>
<p>The <code>docker build -t docker-whale .</code> command takes the <code>Dockerfile</code> in the
current directory, and builds an image called <code>docker-whale</code> on your local
machine. The command takes about a minute and its output looks really long and
complex. In this section, you learn what each message means.</p>
<p>First Docker checks to make sure it has everything it needs to build.</p>
<pre><code>Sending build context to Docker daemon 158.8 MB
</code></pre>
<p>Then, Docker loads with the <code>whalesay</code> image. It already has this image
locally as your might recall from the last page. So, Docker doesn&rsquo;t need to
download it.</p>
<pre><code>Step 0 : FROM docker/whalesay:latest
---&gt; fb434121fc77
</code></pre>
<p>Docker moves onto the next step which is to update the <code>apt-get</code> package
manager. This takes a lot of lines, no need to list them all again here.</p>
<pre><code>Step 1 : RUN apt-get -y update &amp;&amp; apt-get install -y fortunes
---&gt; Running in 27d224dfa5b2

---&gt; eb06e47a01d2
</code></pre>
<p>Then, Docker installs the new <code>fortunes</code> software.</p>

<p>Finally, Docker finishes the build and reports its outcome.</p>

---&gt; 7d9495d03763

</code></pre>
<h2 id="step-4-run-your-new-docker-whale">Step 4: Run your new docker-whale</h2>
<p>In this step, you verify the new images is on your computer and then you run your new image.</p>
<ol>
<li><p>If it isn&rsquo;t already there, place your cursor at the prompt in your terminal window.</p></li>
<li><p>Type <code>docker images</code> and press RETURN.</p>
<p>This command, you might remember, lists the images you have locally.</p>
<pre><code>$ docker images

</code></pre></li>
<li><p>Run your new image by typing <code>docker run docker-whale</code> and pressing RETURN.</p>
<pre><code>$ docker run docker-whale

</ol>
<p>As you can see, you&rsquo;ve made the whale a lot smarter. It finds its own
things to say and the command line is a lot shorter! You may also notice
that Docker didn&rsquo;t have to download anything. That is because the image was
built locally and is already available.</p>
<h2 id="where-to-go-next">Where to go next</h2>
<p>On this page, you learned to build an image by writing your own Dockerfile.
You ran your image in a container. In the next section, you take the first step in sharing your image by
<a href="../../linux/step_five/">creating a Docker Hub account</a>.</p>
