WEBSITE_SWAP_WARMUP_PING_PATH: The path to ping to warm up your site.The documentation mentions two app settings you can use to set up a custom warm-up: This gives the app a chance to run custom warm-up code before the slot is swapped into production. A custom warm-up is a URL that Azure will hit after code is deployed to the offline deployment slot or slots. I did this recently, but ran into a subtle gotcha when I tried to set up a custom warm-up with my ASP.NET Core site. It’s possible to set up a continuous blue-green deployment process on Azure using deployment slots. But the overall time savings and agility gained through CD are tremendous! Of course this requires a lot of trust in my automation and testing before merging code into main. I don’t have time to deploy code by hand. This is why I lean heavily on Continous Deployment (CD) to automatically test and deploy software when it’s merged into my main branch.
