This video goes over two Azure IP addresses used for Azure VM’s. The WireServer IP of 168.63.129.16 and the Azure Instance Metadata Service (IMDS) IP address 169.254.169.254. In the video, I go over what each is used for and then give a demonstration on using the WireServer IP address to query DNS. After that, I use the IMDS REST Endpoint to pull metadata including the Azure environment and scheduled events.

In this video, I demonstrate how to use Postman, a free API development and testing tool, to format URL’s and make requests against web endpoints and use those URL’s to get data in PowerShell. I also give a quick walk through of viewing the data in PowerShell.

This is where my last two articles, Git for System Admin Scripting and Get Started with Git Remote, come together. Microsoft’s Visual Studio Code (VS Code) is a powerful and extendable IDE. VS Code supports Git out of the box. It also supports many programming and scripting languages with Microsoft and 3rd party extensions. In this article, I walk through common tasks that we have already covered, only this time with the native Git integration within VS Code. I also review new functionality with a free 3rd party extension.

In my last post, I eulogized the virtues of using Git for the simplest of scripts. You can find that here. In this post, I go over using Git with a remote repository, namely GitHub.

I spent most of my time in IT as a system admin, on the “Ops” side of DevOps. Over the years, I have accumulated many different batch files and scripts of one type or another. File shares worked well for storing the code I write. I discovered Git and it’s become my main repository for all script related code. Recently, I attempted to make a case to other admins for using Git, but failed to make a convincing case. Below, I lay out my case to why a sysadmin or anyone writing any kind of script should move to Git. I also outline how I use it in an effort to make my case and help anyone interested in getting started with Git.

ARM Templates are written with JSON and are at the core of Azure Resource Manager deployments. I have used and developed templates for months. Although successful, I ran into issues with formatting and syntax this week and decided to take a step back and get a better understanding of the underlying JSON used in these templates. In this post, I start from the beginning, exploring JSON as it relates to ARM templates. Continue reading “JSON and ARM Templates”
Recently I ran into an issue with Authentication and Azure Automation child runbooks. The goal was to call a PowerShell child runbook following the documentation here. I was using the cmdlet method, starting the runbook with the Start-AzureRmAutomationRunbook command. Trying to call the child runbook from the parent, I get the error: Continue reading “Authentication and Azure Automation Runbooks”
I see a lot of potential in Azure Log Analytics. That should go without saying considering the amount of time I have spent learning and documenting it over the past few weeks. One of the most exciting features that adds tremendous flexibility is the ability to log directly to Log Analytics with the Web API. Logging to the Web API enables anything to be written to Log Analytics without the use of the Microsoft Monitoring agent. Continue reading “Azure OMS Log Analytics Step by Step – Data Collector API”
