Azure Bicep: The Smart Way to Handle Azure Resources 🚀

You know how sometimes you’re working with Azure, and you find yourself wrestling with those ARM templates? Yeah, I’ve been there too. They’re super powerful, but man, can they be a headache to read and manage! 😅

Well, guess what? Microsoft came up with this cool thing called Azure Bicep. It’s like ARM templates, but way easier on the eyes (and the brain). Trust me, it’s a game-changer.

So, grab a coffee ☕ (or your beverage of choice), and let’s dive into this Bicep stuff together. Here’s what we’re gonna cover:

  • What is Azure Bicep anyway?
  • How it stacks up against our old friend, ARM templates
  • Why you might want to give Bicep a shot
  • And hey, we’ll even deploy something together! (Don’t worry, I’ll walk you through it step-by-step)

Now that we’ve introduced Azure Bicep, you might be wondering why it’s worth your attention. Let’s explore the key reasons why Bicep is becoming an essential tool for Azure resource management.

Why Should You Care About Azure Bicep? 🤷‍♂️

Bicep addresses many of the pain points we’ve experienced with ARM templates. Here’s why it’s gaining traction:

  1. Azure-Specific Design: Bicep is purpose-built for Azure. It’s deeply integrated with the Azure ecosystem, allowing you to leverage new Azure features as soon as they’re released. This tight integration means you can describe and deploy Azure resources more efficiently.

  2. Simplified Syntax: Remember the complexity of JSON in ARM templates? Bicep significantly simplifies this. It allows you to express your requirements more directly, reducing the cognitive load when writing and reading infrastructure code.

  3. Enhanced Developer Experience: Bicep comes with a suite of developer-friendly features. Things like intellisense, code completion, and validation make the coding process smoother and less error-prone. It’s like having a helpful assistant that makes your Azure resource management more productive.

Azure Bicep to The Rescure

As you can see, Bicep offers a more streamlined approach to defining Azure resources.

Now that we’ve covered why Bicep is valuable, let’s dive deeper into what it looks like in practice. In the next section, we’ll compare Bicep side-by-side with ARM templates, so you can see the differences for yourself. Ready to see Bicep in action?

Understanding Azure Bicep 🏊‍♂️

Now that we’ve covered why Bicep is worth your time, let’s dive into what it actually looks like. Don’t worry – it’s not as complicated as you might think!

First things first: Bicep isn’t here to completely replace ARM templates. Think of it more like a friendly layer on top of them. Both Bicep and ARM templates aim to do the same thing, but Bicep makes the process a whole lot easier.

Let’s look at a real example. Say we want to create a resource group in Azure. Here’s how we’d do it in Bicep:

1
2
3
4
5

targetScope = 'subscription'
resource iaMachsResourceGroup 'Microsoft.Resources/resourceGroups@2022-09-01' = {
  name: 'iaMachsRG'
  location: 'australiaeast'
}

Now, let’s compare that to the equivalent ARM template:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

{
    "$schema": "https://schema.management.azure.com/schemas/2018-05-01/subscriptionDeploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "resources": [
      {
        "type": "Microsoft.Resources/resourceGroups",
        "apiVersion": "2018-05-01",
        "location": "australiaeast",
        "name": "iaMachsRG",
        "properties": {}
      }
    ]
}

See the difference? The Bicep version is more concise and feels more intuitive. You don’t have to wrestle with all those curly braces, quotation marks, or schema references. It’s straightforward and to the point.

This simplicity is one of the main reasons why many Azure users are making the switch to Bicep. It’s not just about writing less code – it’s about writing code that’s easier to understand and maintain.

Why You’ll Love Azure Bicep 🎁

Now that we’ve seen Bicep in action, let’s talk about why it’s winning over so many Azure users. There are quite a few advantages to using Bicep:

  1. Readability: Bicep code is much easier on the eyes compared to JSON. This means you’ll spend less time deciphering code and more time actually getting things done.
  2. Dev-friendly Features: Bicep comes with some great tools that make your life easier. There’s the Azure CLI for managing your Azure resources, the Bicep CLI for working specifically with Bicep files, and even a VS Code extension to supercharge your Bicep coding.
  3. Seamless ARM Integration: Bicep plays nicely with your existing ARM templates. You can convert between the two, which means you’re not starting from scratch if you decide to make the switch.
  4. Modularity: Bicep allows you to break your infrastructure into reusable modules. This means you can write code once and use it many times, saving you time and reducing errors.
  5. Strong Type Checking: Bicep provides better error checking before you deploy. This means you’re more likely to catch issues early, saving you from headaches down the line.

Getting Started with Azure Bicep

  1. Azure CLI: This is your command-line tool for managing Azure resources. It’s available for Windows, macOS, and Linux.
  2. Bicep CLI: This tool is specifically for working with Bicep files.
  3. VS Code Extension: If you use Visual Studio Code, this extension will make writing Bicep code a breeze.

Here’s how to get everything installed:

  1. First, install the Azure CLI. You can find the installation guide here ↗.
  2. Once you have the Azure CLI, installing Bicep is easy. Just run this command: az bicep install.
  3. For the VS Code extension, open VS Code, go to the Extensions marketplace, and search for “Bicep”. It should be the top result.

Bicep VS Code Extenstion

If you’re new to Azure CLI, don’t worry! I’ve got a YouTube video that walks you through the basics: 😊

With these tools in place, you’re all set to start your Bicep journey. In the next section, we’ll create our first Bicep script together. Ready to get your hands dirty with some actual Bicep code?

Let’s Write Some Bicep Code! 📝

Alright, it’s time to roll up our sleeves and write our first Bicep script. Don’t worry if you’re new to this – we’ll go through it step by step, and I’ll explain every bit along the way.

Step 1: Create Your Bicep File

First things first, open up Visual Studio Code and create a new file. Let’s call it main.bicep. This .bicep extension tells VS Code that we’re working with a Bicep file.

Step 2: Write Your Bicep Code

Now, let’s write some Bicep code to create a resource group. Here’s what we’re going to type:

1
2
3
4
5
6

targetScope = 'subscription'

resource iaMachsResourceGroup 'Microsoft.Resources/resourceGroups@2022-09-01' = {
  name: 'iaMachsRG'
  location: 'australiaeast'
}

Step 3: Understanding the Code

Let’s break this down line by line:

  1. targetScope = 'subscription'

    • This line tells Azure that we want to create our resource group at the subscription level. It’s like saying, “Hey Azure, we’re working with the whole subscription here, not just a single resource group.”

  2. resource iaMachsResourceGroup 'Microsoft.Resources/resourceGroups@2022-09-01' = {

    • This line is declaring a new resource. Let’s break it down further:
      • resource: This keyword tells Bicep we’re defining a new resource.
      • iaMachsResourceGroup: This is a name we’ve chosen for this resource within our Bicep file. It’s like a variable name in programming.
      • 'Microsoft.Resources/resourceGroups@2022-09-01': This is the resource type and API version. It tells Azure exactly what kind of resource we’re creating (a resource group) and which version of the API to use.

  3. name: 'iaMachsRG'

    • This is the actual name our resource group will have in Azure. When you look in the Azure portal, you’ll see a resource group with this name.

  4. location: 'australiaeast'

    • This specifies where we want our resource group to be located. In this case, we’re choosing the Australia East data center.

A Note on API Versions

You might be wondering about that @2022-09-01 part in our resource type. This is the API version, and it’s pretty important. Azure is always evolving, and new API versions can introduce new features or changes. By specifying the version, we ensure our code works consistently even if Azure updates things in the future.

The Squiggly Line Mystery

Avoid Hard Coding Values in Your Code

If you’re following along in VS Code, you might notice a squiggly line under ‘australiaeast’. Don’t panic! This is VS Code trying to be helpful. It’s suggesting that hardcoding values like this isn’t the best practice for reusable code.

In a real-world scenario, we might want to make this location a parameter so we can easily change it for different deployments. But for now, as we’re learning, it’s okay to keep it as is. We’ll dive into more advanced practices in future posts!

Ready to Deploy?

Now that we’ve written our Bicep script and understood what each part does, are you ready to see it in action? In the next section, we’ll deploy this script and watch as Azure creates our resource group. Exciting, right?

Using Azure CLI:

Navigate to your Bicep file’s location and run:

1

az deployment sub create --location australiaeast --template-file main.bicep

Post-deployment, check the Azure portal to ensure your resources are up and running.

Wrapping Up Our Bicep Adventure

We’ve come a long way in our Azure Bicep journey, haven’t we? Let’s quickly recap what we’ve learned:

  1. We discovered why Azure Bicep is becoming a go-to tool for managing Azure resources.
  2. We compared Bicep to traditional ARM templates and saw how much cleaner and more intuitive Bicep can be.
  3. We set up our Bicep environment with the necessary tools.
  4. And finally, we created our very first Bicep script to deploy a resource group.

Remember that mysterious squiggly line we encountered in our code? Well, it turns out that line wasn’t just Visual Studio Code being fussy. It was actually giving us a hint about a best practice in Bicep coding – the use of parameters.

What’s Next? Demystifying Bicep Parameters

Speaking of parameters, that’s exactly where our Bicep journey is headed next! In our upcoming article, we’ll dive into Azure Bicep Parameters and finally bid farewell to that pesky squiggly line.
