Quick tip: Invoke-WebRequest and SSL/TLS

If you have every tried using Invoke-WebRequest to get a webpage using SSL, you will most likely have seen the following error message:

Invoke-WebRequest : The request was aborted: Could not create SSL/TLS secure channel.

The simple “fix” for this problem is to tell PowerShell to use TLS 1.2 instead of the default 1.0:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Invoke-WebRequest -Uri "https://some.site.com"

Authenticating to Azure in a release pipeline

When doing automated deployments to Azure, I found that I was missing a single approach for authentication when used both in a release pipeline, and when doing ad hoc testing during development.

I needed something that let me use an Azure Service Principal for automated processes, as well as using my private credentials for other usages.

After many iterations, I think I have something that is worthwhile sharing with others, in the form of simple templates that gives you a kick-start to any Azure project! (more…)

As my followers on social media may have seen already, I have been awarded the Microsoft MVP award in the “Cloud and Datacenter Management” category. For this I’m deeply humbled and grateful.

Getting any kind of recognition for work done is of course highly rewarding in itself, but I’d like to take the opportunity to write down my thoughts on the act of giving and receiving recognition for community work. (more…)
