Deployment Slot Swapping - Excluding a directory

Question

My app has a directory which is dynamic (app creates it and adds some content there).

Whenever I swap a deployment, the dynamic folder is wiped out (because the other deployment does not contain that directory).

Is there a way to prevent this? Maybe a way to exclude a particular directory?

Thanks

Answer 1

There is no way to exclude a folder during the swap. The slots are effectively tow separate sites, and all the files they contain get swapped.

The best option is probably to externalize the data into Azure Storage (blob) or a database.

thanks,
David

Answer 2

Yes I was thinking about blob too.

Btw, will a second slot cost as an additional site?

Answer 3

The cost is per App Service Plan, so since the slot is (typically) in the same Plan (meaning it shares the same VMs), there is no additional cost.
