<p>I am working through &quot;learn kubernetes the hard way&quot; and am at the &quot;bootstrapping the etcd cluster&quot; step: <a href="https://github.com/kelseyhightower/kubernetes-the-hard-way/blob/master/docs/07-bootstrapping-etcd.md" rel="nofollow noreferrer">https://github.com/kelseyhightower/kubernetes-the-hard-way/blob/master/docs/07-bootstrapping-etcd.md</a></p>
<p>I have run into a command that causes a timeout:</p>
<pre><code>somersbmatthews@controller-0:~$ {   sudo systemctl daemon-reload;   sudo systemctl enable etcd;   sudo systemctl start etcd; }
Job for etcd.service failed because a timeout was exceeded.
See &quot;systemctl status etcd.service&quot; and &quot;journalctl -xe&quot; for details.

<p>Here I follow the above recommendations:</p>

<p>but I'm still getting the timeout errors above.</p>
<p>Any help is appreciated, thanks :)</p>

<p>I encountered similar error .
First , I did a mistake in using master-1 ip address in listen-peer-urls,listen-client-urls ,advertise-client-urls &amp; listen-client-urls</p>
<p>Second , try to test if telnet works on telnet  2380.
And if doesnt work , then open firewall on both masters</p>
<p>sudo firewall-cmd --add-port=2380/tcp --permanent</p>
<p>sudo systemctl restart firewalld</p>
<p>Also , it is necessary that both masters should not have considerable time difference.</p>
