Application Insights (AI) is the application performance management (APM) and logging platform for Microsoft Azure. They provide a client instrumentation library for several popular platforms/languages– but there isn’t any official module for PowerShell. In this post I share some new functions that demonstrate how to log telemetry data to AI from PowerShell.Continue reading
Deploying Azure Resource Manager (ARM) templates with the Azure PowerShell command New-AzureRmResourceGroupDeployment can fail for a variety of reasons. One of the more confusing situations can occur when handling template validation errors (Code=InvalidTemplateDeployment). This is because sometimes additional context is missing from the Exception and you have to lookup more information into order to troubleshoot the issue. In this post we will take a closer look at this particular error and how to resolve it.Continue reading
Docker is a powerful container platform originally designed for Linux, but quickly became popular enough to receive native support on Windows. I first read Docker training material that took more of a Linux-first approach and loved what I saw. However my day-to-day work is still typically Microsoft/Azure stack so I was looking for a good book that takes on the nuances of working with Docker in a Windows or Azure environment.
I found Docker on Windows: From 101 to Production with Docker on Windows by Elton Stoneman to be really helpful for that purpose. This post is my quick review of the 1st edition.Continue reading
I recently completed work on a my first compiled binary PowerShell module– these are modules built with C#/.Net code instead of PowerShell code. A few module development basics like project setup, handling help files, and writing unit tests did take some work to figure out. In this article I provide some tips for how to handle these common scenarios to help you get started on new projects.Continue reading
Windows PowerShell’s execution policy is well known feature that helps prevent users from accidentally running malicious scripts. I hit an interesting situation recently where Get-ExecutionPolicy showed that I was allowed to run scripts, but in practice I still couldn’t execute scripts from a .NET application’s hosted runspace. What was the problem? The execution policy settings differed across x64 and x86 processes. Since this problem isn’t covered in the official documentation I figured it deserved a quick write-up.Continue reading
Building scalable systems for the cloud involves leveraging unique design patterns specific to cloud services. In Bill Wilder’s book, Cloud Architecture Patterns: Using Microsoft Azure, he walks through these patterns in detail with practical examples for Microsoft Azure. Although this book is now several years old, most of the patterns still hold up today.Continue reading
A couple years ago I wrote a PowerShell module starter kit (here). The goal was to provide an example for organizing a module using best practices and provide a live repository you could clone and play around with.
I’ve taken that starter kit module and updated it for 2019. Incorporating some new best practices and new usage patterns that I find helpful. Head over to the GitHub link to check it out!
