The container names are resolved to IP addresses of the specific

container, ordered by their scope.</p><p>To activate the NSS modules, "<code class="literal">mymachines</code>"

has to be added to the line starting with

"<code class="literal">hosts:</code>" in

near the end of the <code class="filename">nsswitch.conf</code> line to

make sure that this mapping is only used as fallback, and any DNS

precedence.</p></div><div class="refsect1"><a name="idm140087977495696"></a><h2 id="Example">Example<a class="headerlink" title="Permalink to this headline" href="#Example">¶</a></h2><p>Here's an example <code class="filename">/etc/nsswitch.conf</code>
