<p>Follow this <a href="https://kb.porkbun.com/article/190-getting-started-with-the-porkbun-api">porkbun</a> guide on enabling the api for your domain.</p>
<h2 id="ddns-updater">ddns-updater</h2>
<p><a href="https://github.com/qdm12/ddns-updater">ddns-updater</a> is the program used to update Porkbun's A record of your domain.</p>
<h3 id="docker-install">Docker install</h3>
<p>Install the <a href="https://docs.docker.com/engine/install/debian/">docker</a> package from official docker repositories.</p>
<h3 id="setup">Setup</h3>
<p>Create a directory with config.json inside, and make sure that its owner has a uid of 1000.</p>
<pre><code>mkdir data
touch data/config.json
# Owned by user ID of Docker container (1000)
chown -R 1000 data
# all access (for creating json database file data/updates.json)
chmod 700 data
# read access only
chmod 400 data/config.json
</code></pre>
<p>Configuration for porkbun in config.json</p>
<pre><code>{
"settings": [
{
"provider": "porkbun",
"domain": "domain.com",
"host": "@",
"api_key": "PORKBUN SECRET KEY",
"secret_api_key": "PORKBUN API KEY",
"ip_version": "ipv4"
}
]
}
</code></pre>
<p>Optional <code>"ttl"</code> paramter specifing A record TTL not included.</p>
<h3 id="usage">Usage</h3>
<pre><code>docker run -d -p 8000:8000/tcp -v "$(pwd)"/data:/updater/data qmcgaw/ddns-updater
</code></pre>
<p>This will start a docker container that will start updating the DNS records.
Status updates can be seen in a web server by going to localhost:8000.</p>
