Missing deployment slot support for az functionapp update

[kevin-secrist]

Describe the bug

Hi there!

When attempting to update one of the properties on my function app, I found that az functionapp update does not have slot support. To attempt to work around this I tried using az webapp (which does have slot support) but it gave me an error telling me to use az functionapp instead.

Other commands that may/may not need slot support:

az functionapp config hostname get-external-ip
az functionapp deployment user set
az functionapp deployment user show
az functionapp devops-pipeline create
az functionapp function *

To Reproduce:

Steps to reproduce the behavior. Note that argument values have been redacted, as they may contain sensitive information.

az functionapp update --resource-group <rg> --name <app> --slot staging --set siteConfig.healthCheckPath=/api/HealthCheck

Errors:

az: error: unrecognized arguments: --slot staging

To reiterate, az webapp update does have slot support.

A separate issue that I don't need addressed is that passing in the resourceId of the slot gets ignored, e.g.

az functionapp update --ids /subscriptions/{SubscriptionId}/resourceGroups/{ResourceGroup}/providers/Microsoft.Web/sites/{FunctionApp}/slots/staging --set siteConfig.healthCheckPath=/api/HealthCheck

Ends up silently updating the production slot instead of the staging slot. I imagine this is probably the behavior across all commands though. This is undesired behavior because it will cause an app restart on the production slot when an out-of-rotation slot should have been updated+restarted instead.

Expected Behavior

Update the config on the slot as expected in the same way that it does on the production slot.

Windows-10-10.0.19041-SP0

Hi,

I have just come across this problem. I too need to update the staging slot.

        az functionapp update `
            --name <name> `
            --resource-group <resource group> `
            --set dailyMemoryTimeQuota=<quota> `
            --slot staging

Omitting --slot correctly updates the production slot, but ideally we need a way to update the staging slot.

Are there any alternative ways until the support is added? I'm using azure-cli 2.22.1.

Thanks.

Hi team,

I'm having the same issue that az functionapp update does not support updating httpsonly for slot. It gives "unrecognized arguments: --slot staging" for example
> az functionapp update --name --resource-group --set httpsOnly=true --slot staging
DLL load failed while importing win32file: The specified module could not be found.
unrecognized arguments: --slot staging

Any update on this?

Az.Functions version: 2.0.0

do we have any updates / ways to make this work?
updating staging slot is something we would love to use in our environment.

I know this is not ideal but a work around is to move the production slot first. Swap the slot snd execute the same command again. This will move both production slot and staging slot to the new plan. One downside is that you will have code running from the slot so you just need to swap again at the end.

@kevin-secrist Apologies for the late reply. The similar issue has been discussed here and I see the PR has been merged now #21698. Please let me know if you are still facing the same issue using most recent version of the AzCLI. Awaiting your reply.
