At the current customer I am working for I am creating a lot of VSTS Extensions to deploy Azure Resources.
I want my tasks to be so much user friendly as possible, and one of the things to accomplish this is with Data Source Bindings.
What are Data Source Bindings?
Data source bindings bind a drop-down input field in the UI (e.g. task input) which needs to be dynamically populated with values from ta REST API that needs to be invoked to fetch the list of values.
Where are the Data Sources defined?
The Data sources are defined in the Service Endpoints.
Service endpoints support querying data from external services through REST API.
The data queried can be used to populate task input drop-downs. Continue reading “Make your VSTS extensions smarter with Endpoints Datasource bindings”
During my last project I was setting up a Release Pipeline in VSTS and one of the steps was to create a Sharded MongoDB in Cosmos DB.
I am a big fan of the Azure CLI, which I use quiet often.
I started to create in bash an Azure CLI script but soon I discovered that it was not working well. The script gave no errors, everything seemed to be ok, but I was getting an error when inserting a document that the sharded key was not found/provided.

For a demo Azure Logic App I need to setup an Azure Cognitive Services account for the Computer Vision API.
I set up the resources in Azure using an ARM template so that everything is created in a reproducible way.
My logic app needs a connection to the Cognitive Services, which consists in an API Key and an endpoint.
I was not able to find a template in the Azure Quickstart Templates repo to get this information, so I find it out myself. Continue reading “Get Cognitive Services Keys and Endpoint in an ARM Template”
I am a heavy user of the Azure Cloud Shell, I use it every day working with the CLI 2.0 to deal with my Azure Resources.
If, like me, the first time you started the Cloud Shell and followed the wizard and clicked on the button “Create Storage”, you ended up with a new Resource Group containing a Storage Account with a random name.
I don’t like random names with my resources, so I will show you how to control this and mount the Azure Cloud Shell with a Storage Account of your choice.

I’m using more and more the Azure CLI 2.0, which makes my scripting life with Azure Resources a lot easier.
The default output of the Azure CLI is json, but you can also use other kind of output formats, as described in this blog.
I want to have some variables that I can reuse in other commands, so let’s say I want to get the name of all the Resource Groups which have a tag called Kind with a value VM, I can use the following JMESPath query:
az group list --query "[?tags.Kind=='VM'].name"
The output will be:

For the quick answer jump to the conclusion.
Yesterday I was trying to mount a data volume in a Docker container and using Docker Community Edition for Windows (aka Docker CE for Windows) you first need to share your drives in the Docker settings:
Unfortunately after clicking on “Apply” I got the following error:
A firewall is blocking file Sharing between Windows and the containers.

Today I want to show a really useful Azure feature to help you with the governance of your Azure Subscriptions: Azure Resource Policies:
Resource policies enable you to establish conventions for resources in your organization. By defining conventions, you can control costs and more easily manage your resources. For example, you can specify that only certain types of virtual machines are allowed, or you can require that all resources have a particular tag. Policies are inherited by all child resources. So, if a policy is applied to a resource group, it is applicable to all the resources in that resource group.
How Resource Policies works
First of all, you need a policy definition. Here a description of the structure.
Let’s create one!
You can create policies definitions directly with the Azure Rest API or using PowerShell, the Azure CLI 1.0 or 2.0.
I prefer using PowerShell:
First login in Azure with: Login-AzureRmAccount and if you have more subscriptions, select the right one with Select-AzureRmSubscription.
