Certificates are a pain. App Service provides a way to get a free cert using the App Service Managed Certificate but the down side is that it does not support naked/apex domains (without a prefix like www).
This morning I saw a tweet from Jeff Hollan saying that he uses Tatsuro Shibamura's App Service Acmebot for managing his certs. It's an Azure Durable Function, so I decided to give it a try.
Installing it is super easy and the instructions are crystal clear. In a matter of a few minutes, I was able to install the bot, generate and install a Let's Encrypt certificate for one of my site.
The doc does not say what to do if you delete one of the Web App you configured with the tool so I asked Tatsuro and he said that there's no need to change a setting in the tool.
Also, someone replied to Jeff with another option from Sam Cogan:
