Looking for a way to access keyvault secrets in the invoke Azure function activity in a YAML template,
The secret from the keyvault is the url for the azure function that I want to invoke in the yaml task.
The Issue is Task Invoke Azure function can only be done on a serverless agent but the keyvault secrets cannot be read in the serverless agent.
I have tried to set the variables as required dependency but that is not working. I have linked variable groups to the task the serverless agent is not able to access those secrets, I have also tried to re-assign values to global variables with keyvault secrets in a hosted agent and then invoke azure function, but that also does not work.
Is there a specific way to do this?

I have:
Azure App Service with a Docker container running in it. Inside the Docker container, there is a Python FastAPI Web App.
Azure Key Vault with some App specific secrets in it (e.g. Public API Client Secret for a side service to send requests to)
I'm trying to set secrets to the App.
There are several examples when an app directly reads the secrets from Key Vault (e.g. official MS documentation), but I believe the provisioning should not be the responsibility of the App.
Probably, secrets should be set as environment variables with the CD pipeline (correct me if it's a bad idea). Otherwise, the App knows details about the infrastructure where it's running, which, I guess, is not the best practice.
Is there a proper way to provision Key Vault secrets to the App environment?
I tried to reproduce the same issue in my environment and got the below results
I have created the app service
The azure key vaults supplies a way to store keys & secrets outside of an application, Using access polices we can allow the application to access the keys with in keyvault
To access the keyvault as a environment variables in the azure app service we have to setup the polices mentioned as below
In the app services => identity => click on status is ON
Go to the keyvault and the polices settings click on add polices
And the access polices page set any permissions for keys and secrets
In the select principal page search for the app service name and select then the app service can access as a environment variables
After that we have to add specific secrets in the app service and copy its in secret identifier as below format
#microsoft.keyvault(secretUri={secret url from the keyvault})
After adding the secret it will look like as below
By following the above steps we can access the secrets as a environment variables
I see that in Azure release pipelines, we can read secrets either by creating a key vault based variable group in library or by using the task "Azure Key vault" in pipeline. Both of them do the same thing i.e. reading the secret value from the key vault, with a difference that we can link variable group with multiple pipelines, and the "Azure Key vault" task would remain confined to one pipeline.
I want to understand what is the best practice while reading secrets from Azure key vault in release pipelines. Which of the two approaches is recommended here and why?

Reusability is the biggest difference between them, and it is also the basis for you to decide which way to choose.
If you confirm that your job is a one-time job, then you can choose Azure key vault task. In this case, you do not need to configure the variable group in library and link the library to the release pipeline.
But if you need to reuse it or plan to reuse it in the future, then choose variable group in library, so that you do not need to add the Azure key vault task in each pipeline.
But would you recommend going with pipeline variables when we already
have these secrets in Azure key vault. Will that not duplicate these
secrets in Azure Key Vault and pipeline variables in that case.
I do not recommend that you use those variables that have been set in Azure key vault in pipeline variables. Because the variable in the pipeline will overwrite the value of the variable you set in Azure key vault.
I'm using a pipeline to deploy function app to azure, in my code I have to use certificate server uri(key vault reference in config file) to get permission.How can I get the Secret Identifier value as a variable when deploy to app services.I just want to deploy this variable from keyvault in pipeline automatically.
Here I'm using Azure keyvault Task:
steps:
- task: AzureKeyVault#1
displayName: 'Azure Key Vault: KV-Secrets-Dev'
inputs:
azureSubscription: 'Azure: DEV'
KeyVaultName: 'KV-Secrets-Dev'
and them deploy funtion app with appsettings:
-clientCertificatePfx #Microsoft.KeyVault(SecretUri=$(spdevpfx))
here I can get the certtificate valut from $(spdevpfx),but I just want it as a server URI,how to get it?
You are not able to get the Secret URI with Azure KeyVault Task in Azure DevOps. Explained in the official documentation:
Use this task in a build or release pipeline to download secrets such
as authentication keys, storage account keys, data encryption keys,
.PFX files, and passwords from an Azure Key Vault instance. The task
can be used to fetch the latest values of all or a subset of secrets
from the vault, and set them as variables that can be used in
subsequent tasks of a pipeline.
Workaround
You may use the Azure PowerShell task to get the id of your secret. And then pass it to the next task by setting it to an environment variable.
We are using Azure env injector webhook configuration to inject the env variables from azure keyvault into kubernetes pods. we have a bunch of env variables. each variable is created as a secret in azure keyvault. In POD definition env is loaded from specific secret from azure keyvault.
We would like to create all key:values in one azure keyvault and load all of them using a single secret in POD definition.
please advise
You can leverage the Flex Volume to enable integration between your Kubernetes cluster and your Azure Key Vault instance. The way you can achieve this is explained here. In this article you have all the steps to perform this integration.
Am working on Azure DevOps and Azure KeyVault. Here, am trying to login my Azure account using KeyVault secrets in Azure DevOps Pipelines. For that I followed the Link-1 which is used for fetching the secrets. All the setup is done properly and for checking it, I taken PowerShell task with Inline script as shown in figure where Password is KeyVault Secret:
When the Build is run, it's runned without any error. But, here am getting KeyVault secrets(Password) values as following:
After that, when I tried it for further steps by adding some code for login purpose am getting the error as following:
Could you please suggest me how to get out of this situation
First, Azure Devops will not output varaibles defined as secrets.
Then you have a typo in your script. you should double-quote the password:
$securePassword = "$(Password)" | ConvertTo-SecureString -AsPlainText -Force
Secrets variables need to be mapped before using it in pipeline.You can try below steps.
First, map the secrets to an environment variable in the powershell task
Then use below scripts to refer to the password
$SecurePassword=$env:PASSWORDMAP
