listKeys not supported in variable

[gregjhogan]

If I use listKeys() in a variable, I get the error:

The template function 'listKeys' is not expected at this location

for example:

{
    "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
    "variables": {
        "storageAccountKey": "[listKeys(resourceId('Microsoft.Storage/storageAccounts/mystorageaccount)),'2015-06-15').key1]"
    }
}

Can support for listKeys inside a variable be added?

Adding @ravbhatnagar @rjmax from the ARM team for this request

Ran into the same thing. Not a huge drama of course but it would be nice.

FYI my scenario was I was looking to grab the connection string to my storage that I just created and give it to both my webjob as a connection string in the app service and as output for other parts of my deployment (occurring in octopus deploy).

Do we know if this is available now?

Hi guys, I'm trying to deploy different instances of HDInsight ... but I'm facing an issue since for some of them we would like to link x number of Storage Accounts of for others Y ... I was planning to have an array with the X/Y storage accounts and pass the array with "Take" function ... but one of the properties for the SAs is the Key value ....... running out of ideas :S

The functions in the template language come in two flavors - compile time functions and runtime functions. reference and listKeys are both runtime functions, and are excluded from variables; only compile time functions are supported. . .

[MisinformedDNA]

Can variables be expanded to allow for compile time functions?

[rjmax]

Compile time functions are already supported in variables. Runtime functions are not.

[MisinformedDNA]

OK. Can variables be expanded to allow for runtime time functions?

[rjmax]

Perhaps - we will add this to the list of template enhancements.

@rjmax I too would like the ability to have it process run-time functions. I have to use the same key repeatedly in my template so it would be nice to be able to type out the listkeys function once and save it to a variable then use that much shorter variable repeatedly in the template.

@rjmax I want this so I can append a list of application settings to functionApps on creation. FunctionApps require a storage device resource entry(that uses listKeys), and I need to append a variable array of application settings to those appSettings. Is there any other area where we could concat/union the values together?

Please allow runtime functions to variables section.
