When I reference more than 30 keys from my global Key Vault in ARM template parameter file, then I get the following error in my deployments.
The deployment has specified too many KeyVault parameter references. The maximum of KeyVault parameter references is '30'.
Please help me how to override this limit or what is the alternative to reference more than 30 secrets/keys from Key Vault?
Just create a nested deployment that will reference 30 more secrets and return those as output into the main one, that way you can work around that restriction
One alternative is to store multiple values in a single secret as JSON. You can load that single secret from key vault and then use the json() template function to convert it into an object. Pass the secret to a linked template as a string, then use the json function in that linked template.
This limit has been increased to 256, which is currently the max number of parameters allowed in a template. See: https://github.com/bmoore-msft/AzureRM-Samples/blob/master/keyvault-max-references/azuredeploy.json for a sample.

I am trying to create an Azure Function App which is an EventHub Trigger. The thing is that to connect to Azure Eventhub, I don't have the full connection string. Instead I have the Eventhub SAS token stored as secret in a Key Vault.
I would like to know if in the App Settings section there is a way to build the connection string by passing that token that I get from the key vault.
I have a variable KEYVAULT_SAS_SECRET whose value I want to use in another variable within the App Setting.
Would it be possible to reference the KEYVAULT_SAS_SECRET variable to construct the connection string that is stored in a second variable?
Something like this:
Endpoint=sb://some-namespace.servicebus.windows.net/;SharedAccessKeyName=policy;SharedAccessKey=[KEYVAULT_SAS_SECRET];EntityPath=eventhub-topic.
Thank you very much in advance
Unfortunately it is not possible to reference Azure Function App Settings variable in another App Settings variables.
In your particular case you have to construct EventHub connection string from two App Settings variables directly in your code
I am trying store secrets in azure vault. I used azure sdk apis and I can successfully store/retrieve using those. I wanted to know if it's possible to categorise/group set of secrets under same tag and store them in some path.
I want to group some secrets used by one service, store them in one storage path. The same way for other services is separate storage paths. I couldn't find any way of doing that. Is that possible in azure vault?
In short: no, this is not possible.
Also: you cannot get secrets and their values in a list. If you want to get a list, you'll only get a SecretItem array and you have to call GetSecret on each secret you want to get the actual value for.
You could, however, implement something like this yourself by defining a template for the name of the secret that incorporates the name of the thing you would like to group on. Something like this:
$"{serviceName}-secrets-{secretName}"
This way, you can filter the list to only hold the secrets for the service you want to get them for and get their values.
I have a parameterized connection string in Azure Data Factory Linked Services as below:
Integrated
Security=False;Encrypt=True;Connection Timeout=30;Data
Source=xyz;User ID=admin;Password=password;Initial
Catalog=#{linkedService().LSDBName};
The value for database is passed from a pipeline variable at runtime.
I want to save this connection string to Azure Key Vault, but the issue is that after the value is read from the key vault, the linked service parameter "LSDBName" is not dynamically replaced by the actual value and it tries to connect to "#{linkedService().LSDBName}" as the database name.
Is there any way to secure a dynamically parameterized connection string in key vault? Or a workaround to achieve this?
Thanks!
If you want to store the entire connection string in key vault then you have to pass the connection string in "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;" format. Create separate connection string for each database and store it in key vault with different secrets and then create parameterized linked service in ADF, giving these secrets as parameter.
My idea is using Set Variable Activity+Azure Function Activity.
First step is using Set Variable Activity to get the LinkedService Connection String.
Second Step is passing the variable as parameter into Azure Function Activity. Then use AKV sdk to store the connection string value in the azure function inside.
Incidentally, I think your connection string has been parameterized already, security issues have been avoided. You don't have to store it into AKV again because mostly we read private information from AKV, rather than write store information into AKV in ADF. Just my own opinion.
While developing an ARM template to deploy multiple app services and want to use the key vault to host multiple secret, and we need to include 110 references in the template.
While doing a POC, there is an error message:
The deployment has specified too many Key Vault parameter references.
The maximum of Key Vault parameter references is '30'
Is it possible to go beyond 30?
Your first option should be to consider why you need so many secrets and how you can come up with a better strategy.
Failing that, on the quick and dirty, you can wrap multiple secrets in the a string.
E.g.:
MySecret: value1|value2|value3|value4|value5
They you can use the ARM Template functions to pull out the value you need.
Look in to the array and split functions.
Hopefully you can keep related secrets together and organise them neatly.
I need a way to store hierarchical data in Azure Key Vaults so that I have a structure similar to:
AppName
/Prod
/Data
/Test
/Data
AppName2
/Prod
/Data
...
As far as I can tell I can only store a flat data structure. I am looking to be able to store data similar to Vault by HashiCorp which allows hierarchies.
For instance, in Vault by HashiCorp, I can get data using a 'path': "app/test/TestConnection" and I get the value at the endpoint of the path: TestConnection.
Any suggestion for alternatives would be fine or instruction on how to do what I need to do with Key Vault.
Thanks
Update
I tried some of the suggestions: MySettings--SomeSection--SecretThing, Multiple Vaults and neither works in the manner I need as described above. Not faulting the input but what I want to do just is not available in Key Vault.
#juunas Turns out that your suggestion may be the best solution. I only just discovered in another article that MySettings--SomeSection--Secret translates into something similar in .NET Core:
MySettings: {
SomeSection: "Secret"
}
Since my client wants to use Key Vault we are probably going to go with storing json structured data per a single secret per application.
Any other suggestions are welcome
Key Vault does not support hierarchies for secrets.
To emulate structure, you can do something similar what .NET Core does with its Key Vault configuration provider. You can specify a secret with a name like Settings--SomeCategory--SomeValue, and it'll correspond to the following JSON when loaded:
{
"Settings": {
"SomeCategory": {
"SomeValue": "value goes here"
}
}
}
So essentially you can use a separator to emulate the structure, similar also to how Azure Blob Storage emulates folders.
I would advice against mixing different environment secrets within the same key vault. Access cannot be restricted to some keys, as access is granted and denied on the Key Vault level only. You probably don't want the same persons/applications to be able to access all the different environments, but instead grant access to the production environment to a selected group of users and applications only, and vice versa.
As the Key Vault service by itself doesn't really cost anything, we at least have taken the approach to create one Key Vault per environment, i.e. dev, test and production. Within that key vault the secrets are "structured" by a prefix, i.e. AppName-Data and AppName2-Data. This gives the added benefit, that when moving from dev to test and to production, the references to the secrets don't need to be changed, as they have the same name in all the environments. Just the reference to the Key Vault needs to be changed, and all is set!
