SKILLS & TRICKS
This solution is based on the letsencrypt-webapp-renewer. It uses the same core library than the Azure Lets Encrypt site extension, but it is run as a WebJob. It can (should) be installed on its own web app, and supports multiple target websites. The author of the letsencrypt-webapp-renewer has made thorough instructions, so I won't copy them here. When granting the service principal rights, you may want to only add Website Contributor and Web Plan Contributor instead of Contributor rights. The only thing needed in addition to those instructions is the support by the web app itself. SOLUTIONImplementing ACME support in the web appThe ACME process involves a step for authenticating target hostname. There are a few ways of achieving this, but the default in this scenario is to use the HTTP challenge. This involves making a certain data available in a certain URL. The letsencrypt-webapp-renewer handles putting the data to target web app's wwwroot folder via Kudu, but it cannot make it available via HTTP itself. This can be easily implemented with the StaticFiles middleware from Microsoft. Without further ado, here's the code as an extension method. Example use in Startup.cs: If you encounter any errors, make sure to look at the Web Job logs from the Web App you installed the letsencrypt-webapp-renewer Web Job.
