Problem in my local paradise: Func CLI doesn't upgrade

Last Friday, I encountered an issue while trying to run my Azure Function locally using VS Code. Despite having installed the Azure Function extension and the Azure Functions Core Tools, I was unable to execute the func start command without encountering an error saying that no functions could be found. 

In this post, I will share the various troubleshooting steps I took, what didn’t work, and how I ultimately resolved the issue. Spoiler alert: everything is now working correctly.


The Problem

My Azure Function is a .NET 8 Isolated HTTP trigger. When I attempted to execute the func start command, it failed to find any functions. A quick look at the documentation, I discovered that version 4 of the Core Tools was required for type Isolated process. However, I had already installed version 4 via the update popup in VS Code.

VS Code tool update

Something was wrong. I tried func --version and it returned 3.x.xx, weird... And this is how I knew there was a problem.


Failed attempts

Following the Azure Functions Core Tools documentation I found that there were multiple methods to install the Core Tools. Because that laptop was on Windows 11, I started by downloading the func-cli-x64.msi installer and run it. It didn't work, the version 3 was still there.

I tried to install the Core Tools v4 using NPM: npm install -g azure-functions-core-tools@4. It didn't work.

I tried to uninstall the version 3 with npm uninstall -g azure-functions-core-tools. I tried using the command palette in VSCode

VS Code uninstall Core Tool

Still nothing was changing anything, the version 3 was still there.


The Solution

What works, was using Chocolatey command choco uninstall azure-functions-core-tools to uninstall the version 3. Some how, it must have been install at the different location or some "config" got lost at some point (it's a developer laptop after all), and the other methods (npm, msi, vscode) couldn't see that version 3 was installed.

After that, I installed the version 4 using NPM npm install -g azure-functions-core-tools@4. And it worked! The func --version returned 4.0.5571 and the func start command found my function.

I wrote this quick post hoping that it can help someone else, as I cannot be the only one with this problem.

Suggestion of the week

  • Include diagrams in your Markdown files with Mermaid (Martin Woodward, Adam Biagianti) - This is very interesting. For a simple little diagram, we can now do that in text in the same document... Looking forward to trying it. Mermaid is also supported in Azure DevOps

Author: Matthew McConaughey

This autobiography is funny, light, interesting, and even weird at some moments. But you know what? I liked it. I totally kept some quotes, as I found them good. I partially read it and listen to it. The audio version is done by Matthew and it's nice to hear him telling us his story.

Every Tool's a Hammer: Life Is What You Make It
 

(Adam Savage) 

- I really liked this book. In fact, As I was reading the first chapter I was "earing" Adam's voice. So instead of creating that voice in my head I bought the audiobook and let Adam himself tells me his story. This is the best book I listen to this year. It was inspiring and empowering.

How to configure a secured custom domain on a Azure Function or website

I wanted to create this tutorial for a long time. How to map a naked domain on an Azure resource. It looks so complicated, but once you know what to do it's kind of simple in fact. In this post, I will share the three simple steps to do exactly this.

Step 1: Add Custom Domain


The first step is to map a domain on the application. The method I will explain uses a "www" domain (ex: www.fboucher.dev). To map directly a naked domain (ex: fboucher.dev) you would need to buy a wildcard certificate. However, I will show you in step three how to walk around this issue by using DNS rules.

From the Azure portal, open the Azure Function or App Service. From the left menu search for "custom", click the Custom domains option. In this panel click the button Add custom domain, and enter your www domain.



Click the validate button and follow the instruction to make the connection between the App Service and your domain provider.

Step 2: Adding a Certificate


Now that your custom domain is mapped, let's fix the "not secure" warning by adding a certificate. From the Azure portal return in the App blade. Repeat the previous search for "custom", and select the option TLS/SSL settings. Click the Private Key Certificates, and the Create App Service Managed Certificate button. Select the domain previously added and saved. It will take a few moments to create the certificate.



Go back in the Custom domains blade and click the Add binding button. Select the domain and certificate, don't forget to select the SNI SSL option and click the Add Binding button.




Step 3: Create the DNS Rules

Create an account in cloudflare.com and add a site for your domain. We will need to customize the DNS and create some Page Rules.



On the cloudflare.com note the 2 nameservers addresses. Go to the origin name provider (in my case godaddy) and replace the names of the nameservers with the value found on cloudflare.



Create a rule that will redirect all the incoming traffic from the naked-domain to www.domain. On the option on the top, click the Pages Rules (B). Then Click the Button Create Page Rule



In the field for If the URL matches: enter the naked-domain follow by /*. That will match everything coming from that URL

For the settings select Forwarding URL and 301- Permanent Redirect. Then the destination URL should be https://www. with your domain and /$1.

  An incredible adventure yes around the globe, but more important over the personal limits. I found this book very inspiring. I felt following him across the Antarctica... In the blizzard or in those deep moment. Great memoir, great adventure.
