Announcing the AI Toolkit for Visual Studio Code (John Lam) - Nice! The favorite editor of so many now have an AI extension! I missed the Microsoft Build sessions with the demos. Lucky me they are available on demand!
I used to hardcode my password in my demos and code samples. I know it's not a good practice, but it's just for demo purposes, it cannot be that dramatic, right? I know there are proper ways to manage sensitive information, but this is only temporary! And it must be complicated to remove all the passwords from a deployment... It turns out, IT IS NOT difficult at all, and that will prevent serious threats.
In this post, I will share how to remove all passwords from a docker-compose file using environment variables. It's quick to setup and easy to remember. For production deployment, it's better to use secrets, because environment variables will be visible in logs. That said, for demos and debugging and testing, it's nice to see those values. The code will be available on GitHub. This deployment was used for my talks during Azure Developers .NET Days: Auto-Generate and Host Data API Builder on Azure Static Web Apps and The most minimal API code of all... none
The Before Picture
For this deployment, I used a docker-compose file to deploy an SQL Server in a first container and Data API Builder (DAB) in a second one. When the database container starts, I run a script to create the database tables and populate them.
As we can see, the password is in clear text twice, in the configuration of the database container and in the parameter for sqlcmd when populating the database. Same thing for the DAB configuration file. Here the data-source node where the password is in clear text in the connection string.
The easiest password instance to remove was in the sqlcmd command. When defining the container, an environment variable was used... Why not use it! To refer to an environment variable in a docker-compose file, you use the syntax $$VAR_NAME. I used the name of the environment variable MSSQL_SA_PASSWORD to replace the hardcoded password.
/opt/mssql-tools/bin/sqlcmd -U sa -P $$MSSQL_SA_PASSWORD -d master -i /startrek.sql
Second Pass: .env File
That's great but the value is still hardcoded when we assign the environment variable. Here comes the environment file. They are text files that holds the values in key-value paired style. The file is not committed to the repository, and it's used to store sensitive information. The file is read by the docker-compose and the values are injected. Here is the final docker-compose file:
Note the env_file directive in the services definition. The file .env is the name of the file used. The ${SA_PWD} tells docker compose to look for SA_PWD in the .env file. Here is what the file looks like:
SA_PWD=This!s@very$trongP@ssw0rd
Conclusion
Simple and quick. There are no reasons to still have the password in clear text in the docker compose files anymore. Even for a quick demo! Of course for a production deployment there are stronger ways to manage sensitive information, but for a demo it's perfect and it's secure.
During Microsoft Build Keynote on day 2, Julia Liuson and John Lambert talked about how trade actors are not only looking for the big fishes, but also looking at simple demos and old pieces of code, looking for passwords, keys and sensitive information.

In this post, I will share a few things that we need our attention when deploying a .NET isolated Azure Function from GitHub to Azure using the Zip Deploy method. This method is great for fast deployment and when your artefacts are zipped in a package.
Note The complete code for this post is available on GitHub
Understanding Zip Push/Zip Deploy
Zip Push allows us to deploy a compressed package, such as a zip file, directly to Azure. It could be part of a continuous integration and continuous deployment (CI-CD) or like in this example it could replace it. This approach is particularly useful when you want to ensure your artifacts remain unchanged across different environments or when aiming for the fastest deployment experience for users.
While CI-CD is excellent for keeping your code up-to-date, zip deployment offers the advantage of speed and consistency. It eliminates the need for compilation, leading to quicker uploads and deployments.
Preparing Your Package
It’s crucial to package with all necessary dependencies the code required. There is no operation to fetch any external packages during the deployment, the zip file will be decompressed and that's it. The best way to ensure you have everything you need is to publish your code, to a folder and then go in that folder and zip all the files.
dotnet publish -c Release -o ./out
Don't zip the folder, it won't work as expected.
You need to go inside the folder and select all the files and zip them to create your deployment artefact.
The next step is to make your artefact available online. There are many ways, but for this post we are using GitHub Realease. From the GitHub repository, create a new release, upload the zipped file created earlier and publish it. Note the URL of zipped files from the release.
Preparing The ARM Template
For this one-click deployment, we need an Azure Resource Manager (ARM) template. This is a document that describes the resources that we want to deploy to Azure. To deploy the zipped file into the Azure Function there are two particularities that required our attention.
Here we define an Windows Azure Function and the WEBSITE_RUN_FROM_PACKAGE needs to be set to 1. The WEBSITE_RUN_FROM_PACKAGE is the key that tells Azure to use the zip file as the deployment artefact.
Then to specify where the zip file is located we need to add an extension to the Azure Function.
The packageUri property is the URL of the zipped file from the GitHub release. Note the dependsOn property that ensures the Azure Function is created before the extension is added. The complete ARM template is available in the GitHub repository.
One-click Deployment
When you have your artefact and the ARM template uploaded to your GitHub repository, you can create a one-click deployment button. This button will take the user to the Azure portal and pre-fill the deployment form with the information from the ARM template. Here is an example of the button for markdown.
[](https://portal.azure.com/#create/Microsoft.Template/uri/https%3A%2F%2Fraw.githubusercontent.com%2FFBoucher%2FZipDeploy-AzFunc%2Fmain%2Fdeployment%2Fazuredeploy.json)
The has three parts, the first is the image that will be displayed on the button, the second is the link to the Azure portal and the third is the URL of the ARM template. The URL of the ARM template is the raw URL of the file in the GitHub repository, and it needs to be URL encoded. The URL encoding can be done using a tool like URL Encode/Decode.
Final Thoughts
Zip deployment is a powerful tool in your Azure arsenal by itself of part of a more complex CI-CD pipeline. It's a great way to make it easier for people to deploy your solution in their Azure subscription without having to clone/ fork the repository.

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.
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
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.
