How to Use Github Professionally (Aaron Stannard) - This post is great! Tons of information and best practices (with an explanation of why its a best practice).
I really enjoyed this book. Yes it's light and funny, but don't get fool, there is a deeper message here. I think Jessy wins his challenge by going into a monastery so we don't have to. We all have what it takes to live a more purposeful life, we just need to pause. Showdown, to go faster, do less to do more... Embrace the silence.

It's so nice to be able to add some serverless components in our solution to make them better in a snap. But how do we manage them? In this post, I will explain how to create an Azure resource manager (ARM) template to deploy any Azure Function and show how I used this structure to deploy an open-source project I've been working on these days.
Part 1 - The ARM template
An ARM template is a JSON file that describes our architecture. To deploy an Azure Function we need at least three recourses: a functionApp, a service plan, and a storage account.
The FunctionApp is, of course, our function. The service plan could be set as dynamic or describe the type of resource that will be used by your function. The storage account is where is our code.
In the previous image, you can see how those components interact more with each other. Inside the Function, we will have a list of properties. One of those properties will be the Runtime, for example, in the AZUnzipEverything demo, it will be dotnet. Another property will be the connection string to our storage account that is also part of our ARM template. Since that resource doesn't exist yet, we will need to use the dynamic code.
The Function node will contain a sub-resource of type storageAccount. This is where we will specify where is our code, so it cant be clone to Azure.
Building ARM for a Simple Function
Let's see a template for a simple Azure Function that doesn't require any dependency, and we will examine it after.
The first resources listed in the template is the Account Storage. There nothing specific about it.
The Service Plan
The service plan is the second resource in the list. It's important to notice that to be able to use the SKU Dynamic you will need at least the API version of apiVersion to be "2018-02-01". Then you specify the SKU.
"sku": {
"name": "Y1",
"tier": "Dynamic"
}
Of course, you can use the other SKU if you prefer.
The Function App
Final resources added to the mixt, and this is where all the pieces are getting together. It's important to notice that the other in which the resources are listed are not considered by Azure while deploying (it's only for us ;) ). To let Azure knows you need to add dependencies.
This way the Azure Function will be created after the service plan and the storage account are available. Then in the properties we will be able to build the ConnectionString to the blob storage using a reference.
The last piece of the puzzle is the sub-resource sourcecontrol inside the FunctionApp. This will define where Azure should clone the code from and in which branch.
To be sure that everything is fully automatic the properties publishRunbook and IsManualIntegration must be set as true. Otherwise, you will need to do a synchronization between your Git (in this case on GitHub), and the Git in Azure.
Of course, all the source code of both the Azure Function and the ARM template are available on GitHub, but let me highlight how the containers are defined from an ARM template.
Just like with sourcecontrol, we will need to add a list of sub-resources to our storage account. The name MUST start by 'default/'.
Part 2 - Four Deployment Options
Now that we have a template that describes our needs we just need to deploy it. There are multiple ways it could be done, but let's see four of them.
Deploy from the Azure Portal
Navigate to the Azure Portal (https://azure.portal.com), from your favorite browser and search for "deploy a custom template" directly in the search bar located at the top of the screen (in the middle). Or go at https://portal.azure.com/#create/Microsoft.Template. One in the Custom deployment page, click on the link Build your own template in the editor. From there, you can copy-paste or upload your ARM template. You need to save it to see the real deployment form.
Deploy with a script
Would it be in PowerShell or in Azure CLI you can easily deploy your template with these two commands.
In Azure CLI
# create resource group
az group create -n AzUnzipEverything -l eastus
# deploy it
az group deployment create -n cloud5mins -g AzUnzipEverything --template-file "deployment\deployAzure.json" --parameters "deployment\deployAzure.parameters.json"
In PowerShell
# create resource group
New-AzResourceGroup -Name AzUnzipEverything -Location eastus
# deploy it
New-AzResourceGroupDeployment -ResourceGroupName AzUnzipEverything -TemplateFile deployment\deployAzure.json
Deploy to Azure Button
One of the best way to help people to deploy your solution in their Azure subscription is the Deploy to Azure Button.
You need to create an image link (in HTML or Markdown) to this to a special destination build in two-part.
However, this URL needs to be encoded. There is plenty of encoders online, but you can also do it from the terminal with the following command (A big thanks to @BrettMiller_IT who showed me this trick during one of my live streams).
Clicking the button will bring the user at the same page on the Azure Portal but in the user subscription.
Azure DevOps Pipeline
From the Azure DevOps portal (https://dev.azure.com), select your project and create a new Release Pipeline. Click on the + Add an artifact button to connect your Git repository.
Once it's added, you need to add a task the current job. Click on the link 1 job, 0 task (4). Now you just need to specify your Azure subscription, the name of the resource group and select the location of your ARM template inside your repository. To make the deployment automatic with each push in the repository, click that little lightning bolt and enable the Continuous deployment trigger.
Wrapping-up
Voila, you know have four different ways to deploy your Azure Function automatically. But don't take my word for it, try it yourself! If you need more details you can visit the project on GitHub or watch this video where I demo the content of this post.
I recently presented, a workshop at the TOHack to get started with Azure. The goal was to try different Azure services, and see how we could augment an existing website using serverless function and artificial intelligence. (Aussi disponible en français)
During this workshop, a website is deployed automatically from GitHub. Then by adding an Azure Function and using the Vision API of Azure Cognitive Services, the final solution is able to detect when uploaded pictures are or not dogs and keep our image folder "clean". We call that application: The automatic Not a Dog application.
The step by step instruction with the code can be found on GitHub - Not-a-Dog-Workshop. The workshop can be done in about 45-60 minutes.
I also did a video that is available on my YouTube channel:

In a project using Azure Logic Apps that I am working on, I needed to manipulate strings. I could create APIs or Azure Functions, but the code is very simple and is not using any external libraries. In this post, I will show you how to use the new Inline Code to execute your code snippet directly inside your Logic Apps.
Quick Context
The Logic App will read a file from my OneDrive (it will also work with DropBox, Box, etc.). Here an example of the file:
Nice tutorial that explains how to build, using postman, an efficient API.[cloud.azure.postman.tools]
The goal is to extract tags, contained between the square brackets, from the text.
Logic App: Get File Content
From the Azure Portal, create a new Logic App by clicking the big green "+" button in the top left corner and searching for Logic App.
For this demo, I will use the Interval as a trigger because I will execute the Logic App manually.
The first step will be a Get File Content action from the OneDrive connector. Once you authorized Azure to access your OneDrive folder, select the file you want to read. For me, it's /dev/simpleNote.txt
Integration Account
To access the workflowContext the Azure Logic App required an Integration account. Next step would be to create one. Save the current Logic App, and click on the big "+" button in the top right corner. This time search for integration. Select Integration Account, and complete the form to create it.
We now need to assign it to our Logic App. From the Logic App blade, in the options list select Workflow Settings. Then select your integration account, and don't forget to save!
Logic App: Inline Code
To add the action at the end of your workflow, click the New step button. Search for Inline Code, and select the action Execute JavaScript Code.
Before copy-pasting the code into the new Inline Code action let's have a quick look.
var note = "" + workflowContext.actions.Get_file_content.outputs.body;
var posTag = note.lastIndexOf("[") + 1;
var cleanNote = {};
if(posTag > 0){
cleanNote.tags = note.substring(posTag, note.length-1);
cleanNote.msg = note.substring(0,posTag-1);
}
return cleanNote;
On the first line, we assign a variable note the content of the Get_file_content outputs. We access it using the workflowContext. This context has access to the trigger and the actions. To find the name of the action you can replace the spaces by the underscore character "_".
You can also switch to Code View, and see the name of all components from the JSON code.
Logic App: Use Inline Code Result
Of course, you can use the output of your Inline Code with other steps. You just need to use the Result from the dynamic content menu.
If for some reason the dynamic content list doesn't contain your Inline Code, you can always add the code directly @body('Cleaning_Note')?['body'].
Your Logic App should now look like this:
Verdict
The Inline code is very promising. Right now it's limited to JAvaScript and cannot access variable nor loops. However, for simple code that doesn't require any references, it's easier to maintain and deploy. You can learn more about what is exactly covered or not here.
And it works as this result shows.

Nice book. There is always a good story to make a correlation with his current point. Then it could go in a different direction with another story. All the stories are complementary and are adding layer by layer to the more complex message that is delivered to us. Easy to read, enjoyable from the beginning until the last word.
You are done with your code and you are ready to deploy it in Azure. You execute the PowerShell or Bash script you have and BOOM! The error message saying that this name is already taken. In this post, I will show you a simple way to look like a boss and make your deployment working all the time.
____ with given name ____ already exists.
The tricks other use
You could try to add a digit at the end of the resource name (ex: demo-app1, demo-app2, demo-app123...), but that’s not really professional. You could create a random string and append it to the name. Yes, that will works, once. If you are trying to redeploy your resources that value will change, therefore it will never be the same.
The solution would be to have a unique string that is constant in our environment.
The solution
The solution is to use the function UniqueString() part of the Azure Resource Manager (ARM) template. If we look in the documentation, UniqueString creates a deterministic hash string based on the values provided as parameters. Let’s see a quick example of an ARM template to deploy a website named demo-app.
If you try to deploy this template, you will have an error because the name demo-app is already taken... no surprise here.
Let’s create a new variable suffix and we will use the Resource Group Id and Location as values. Then we just need to append this value to our name using the function concat().
It’s that simple! Now every time you will deploy a unique string will be added to your resource name. That string will always be the same for a Resource Group-Location deployment.
Because some resource types are more restrictive than others you may need adapt your new name. Maybe the name of your resource plus those thirteen characters hash will be too long... No problem, you can easily make it shorter and all lower case just by using substring() and toLower().
Voila, and now by using ARM template you can deploy and redeploy without any problem reproducing the same solution you built. To learn move about the ARM template you can jump in the documentation, where you will find samples, step-by-step tutorials and more.
If you have a specific question about ARM templates or if you would like to see more tips like this one, don't hesitate to ask in the comments section or reach out on social media!

A really interesting book that helps to focus and keep in mind the most important. I didn't read it with a purpose of business really, but it did make me remember past experiences and it was easy to make the relationship between success and when the story was clear. Take the time to read it, do the exercises/ reflections required... it's worth it.
