<h1>Deploy a service to the swarm</h1>
<p>After you <a href="../create-swarm/index">create a swarm</a>, you can deploy a service to the swarm. For this tutorial, you also <a href="../add-nodes/index">added worker nodes</a>, but that is not a requirement to deploy a service.</p> <ol> <li> <p>Open a terminal and ssh into the machine where you run your manager node. For example, the tutorial uses a machine named <code class="language-plaintext highlighter-rouge">manager1</code>.</p> </li> <li> <p>Run the following command:</p> <div class="highlight"><pre class="highlight" data-language="">$ docker service create --replicas 1 --name helloworld alpine ping docker.com

</pre></div>  <ul> <li>The <code class="language-plaintext highlighter-rouge">docker service create</code> command creates the service.</li> <li>The <code class="language-plaintext highlighter-rouge">--name</code> flag names the service <code class="language-plaintext highlighter-rouge">helloworld</code>.</li> <li>The <code class="language-plaintext highlighter-rouge">--replicas</code> flag specifies the desired state of 1 running instance.</li> <li>The arguments <code class="language-plaintext highlighter-rouge">alpine ping docker.com</code> define the service as an Alpine Linux container that executes the command <code class="language-plaintext highlighter-rouge">ping docker.com</code>.</li> </ul> </li> <li> <p>Run <code class="language-plaintext highlighter-rouge">docker service ls</code> to see the list of running services:</p> <div class="highlight"><pre class="highlight" data-language="">$ docker service ls

ID            NAME        SCALE  IMAGE   COMMAND

</pre></div>  </li> </ol> <h2 id="whats-next">What’s next?</h2> <p>Now you’ve deployed a service to the swarm, you’re ready to <a href="../inspect-service/index">inspect the service</a>.</p>
