I am exposing it to the internet using DuckDNS.</p><h2>Dependencies</h2><pre><code><div class="highlight"><span></span>sudo apt update <span class="o">&&</span> sudo apt install certbot -y </div></code></pre><h2>Get the Certificate</h2><pre><code><div class="highlight"><span></span>sudo certbot certonly --manual --preferred-challenges dns-01 --email senpai@email.com -d mydomain.duckdns.org </div></code></pre><p>After you accept that you are okay with you IP address being logged, it will prompt you with updating your dns record. You need to create a new <code>TXT</code> record in the DNS settings for your domain.</p><p>For DuckDNS users it is as simple as entering this URL in their browser:</p><pre><code><div class="highlight"><span></span>http://duckdns.org/update?domains<span class="o">=</span>mydomain<span class="p">&</span><span class="nv">token</span><span class="o">=</span>duckdnstoken<span class="p">&</span><span class="nv">txt</span><span class="o">=</span>certbotdnstxt </div></code></pre><p>Where <code>mydomain</code> is your DuckDNS domain, <code>duckdnstoken</code> is your DuckDNS Token ( Found on the dashboard when you login) and <code>certbotdnstxt</code> is the TXT record value given by the prompt.</p><p>You can check if the TXT records have been updated by using the <code>dig</code> command:</p><pre><code><div class="highlight"><span></span>dig navanspi.duckdns.org TXT |
