title: How to add a edge/testing package to Alpine Linux?
body: <p>I have an Azure Linux WebApp using docker-compose to run three containers: Asp.Net Core 3.1 WebApp, Nginx as reverse proxy and an Asp.Net Core WebJob (SKD 3) to gerenate PDF reports. The WebApp is at <a href="https://pdf.ricardogaefke.com" rel="noreferrer">https://pdf.ricardogaefke.com</a>. </p>
  
  <p>The problem is: the PDF generated has a QrCode with a link to check on it online and I was facing a problem while running the WebJob ("<code>libgdiplus</code> was not found) and I tried to install this <a href="https://pkgs.alpinelinux.org/package/edge/testing/x86/libgdiplus" rel="noreferrer">libgdiplus package</a>. This problem is related to <code>System.Drawing</code> Namespace.</p>
  
  <p>The problem is that package is in a edge/testing version and it cannot be installed using <code>apk add</code> command. How can I install this package?</p>
