Provide "remove additional files at destination"

[Scooletz]

After going through documentations I found no information about it, so I'm raising this issue.

Remove additional files at destination as in Azure/Azure-Functions#564 is not available as a publish option.

[AmrutaKawade]

Remove additional files at destination option is available in msdeploy. For function action we use kudu zip deploy method for deployment. as per kudu documentation

Deletion of files no longer in the build: When a new build is deployed with zipdeploy, files and directories that were created by the previous deployment but are no longer present in the build will be deleted. Any other files and directories found in the site that aren't being overwritten by the deployment, such as those placed there via FTP or created by your app during runtime, will be preserved.

It should be handled automatically

Thank you for the response @AmrutaKawade I'm aware of the kudu zip deploy, but I fail to find it in the documentation for this actions provided on the action page https://github.com/marketplace/actions/azure-functions-action

@N-Usha Please check this issue. Some things are missing in documentation.

[N-Usha]

I added this detail to the documentation. Closing this issue. Thanks!

Hey @N-Usha for sake of reference I'm adding the commit that addresses this issue 16fca3c

@AmrutaKawade According to the updated doc

"Remove additional files at destination" is not supported by Kudu deploy method which is used in this action and should be handled separately.

so I think that your comment #33 (comment) might not be applicable. As far as I see it, it makes this issue valid again, because it intent was not to have a documentation updated, but rather address the lack of functionality.

I've just confirmed the following (undesired) scenario:

1. New file added to git and branch pushed to Github
2. Deployment triggered with functions-action in it. Destination: Linux Premium Function App
3. I can see the new file on the Function App / App Files page in Azure Portal
4. I remove the file and commit/push
5. Deployment triggered
6. File is still visible in the App Files.

I was exploring Github Actions as a replacement for an Azure DevOps pipeline (that would make our setup much simpler) but with this missing feature I don't think it's ready yet. Hopefully it's on the roadmap.

So @N-Usha, how do we delete old functions?

The Azure portal shows

And there's no obvious way to get a yaml deployment with azure/azure-functions to clear them out? And by not clearing them out, I see a bunch of ERROR noise in my logs at app startup regarding bad bindings for functions that I've already deleted in my source.
