Azure DevOps Work Item Hierarchy Reports in PowerBI

Azure Pipeline Parameters

In a previous post, I did a deep dive into Azure Pipeline variables. That post turned out to be longer than I anticipated, so I left off the topic of parameters until this post. Type: AnyIf we look at the YML schema for variables

Executing JMeter Tests in an Azure Pipeline

Microsoft have deprecated Load Testing in Visual Studio. Along with this, they have also deprecated the cloud load testing capability in Azure/Azure DevOps. On the official alternatives document, several alternative load testing tools and platforms are mentioned, including JMeter. What is not clear

Azure Pipeline Variables

I am a big fan of Azure Pipelines. Yes it’s YAML, but once you get over that it’s a fantastic way to represent pipelines as code. It would be tough to achieve any sort of sophistication in your pipelines without variables. There

Azure DevOps Build and Test Reports using OData and REST in PowerBI

I have been playing with the Azure DevOps OData service recently to start creating some reports. Most of my fiddling has been with the Work Item and Work Item Board Snaphot entities, but I recently read a great post focused more on Build metrics

Since Microsoft acquired GitHub, and the anti-Microsoft folks had calmed down, there have been a number of interesting developments in the GitHub ecosystem. If you’ve ever read one of my blogs or attended any events that I’ve spoken at, you’ll know

Lessons about DevOps from 3D Printing

It's no surprise that I'm passionate about DevOps. I think that has to do with my personality - my top five StrengthsFinder strengths are Strategic, Ideation, Learner, Activator, Achiever. I love the combination of people and tools that DevOps brings together. Being deeply technical

.NET Core Multi-Stage Dockerfile with Test and Code Coverage in Azure Pipelines

I read a great blogpost recently by my friend and fellow MVP Jakob Ehn. In this post he outlines how he created a multi-stage Dockerfile to run .NET Core tests. I've always been on the fence about running tests during a container build -

Source Control

Modernizing Source Control - Migrating to Git

I remember when I first learned about Git circa 2012. I was skeptical - you can change history? What kind of source control system let you change history? However, it seemed to have huge momentum and so I started learning how to use it.

Release Management

Implement an Azure DevOps Release Gate to ServiceNow

I'm currently doing some work with a customer that is integrating between ServiceNow and Azure DevOps (the artist formerly known as VSTS). I quickly spun up a development ServiceNow instance to play around a bit. One of the use-cases I could foresee was a

Pimp Your Consoles on Windows

I spend a fair amount of time in consoles - specifically PowerShell and Bash (Windows Subsystem for Linux) on my Windows 10 machine. I also work with Git - a lot. So having a cool console that is Git aware is a must. I

Serverless Parallel Selenium Grid Testing with VSTS and Azure Container Instances

I've written before about Selenium testing (Parallel Testing in a Selenium Grid with VSTS and Running Selenium Tests in Docker using VSTS and Release Management). The problem with these solutions, however, is that you need a VM! However, I was setting up a demo

Terraform all the Things with VSTS

I've done a fair amount of ARM template authoring. It's not as bad as XML, but the JSON can get laborious. A number of my colleagues use Terraform templates and I was recently on a project that was using these templates. I quickly did

Managing Credentials and Secrets in VSTS Release Management

Releases almost always require some kind of credentials - from service credentials to database usernames and passwords. There are a number of ways to manage credentials in VSTS release management. In this post I'll look at a couple of common techniques. For brevity, I'm

Auditing VSTS Client Access IPs

Visual Studio Team Services (VSTS) is a cloud platform. That means it's publicly accessible from anywhere - at least, by default. However, Enterprises that are moving from TFS to VSTS may want to ensure that VSTS is only accessed from a corporate network or

VSTS, One Team Project and Inverse Conway Maneuver

Tip: Creating Task Groups with Azure Service Endpoint Parameters

I've been working on some pretty complicated infrastructure deployment pipelines using my release management tool of choice (of course): VSTS Release Management. In this particular scenario, we're deploying a set of VMs to a region. We then want to deploy exactly the same setup
