I am very honored to prepare an Azure Bicep session for the Azure Dominicana meetup group and would like to thank Gregory for extending his invitation.
As you know, the Azure Bicep language brings a new Infrastructure as a Code (IaC) approach to managing your Azure resources in a clean way. In addition, we also have a classic ARM JSON template that is traditionally used to define Azure infrastructure resources in a declarative way. However, it is not easy to author and maintains ARM JSON templates when your project grows in complexity.
That is when Azure Bicep comes into play, to simplify the management of your infrastructure while re-using code. So, please join my session and I will explain to you how to start using Azure Bicep and easily manage your cloud infrastructure.

But, I have good news for you – Microsoft infrastructure team has been working on new language to ease this process. Thus, an Azure Bicep language is created to simplify management of your infrastructure while re-using the code.
In this, I have introduced new features and capabilities of Azure Bicep v0.5 & v0.6 language. You also see demos on how it is simple to create, manage a modularized Azure infrastructure-as-code, while using familiar tools and extensions on VS Code.
The infrastructure-as-code (IaC) is not a just a “buzzword”, it is brought by a necessity to manage your digital estate more predictably while source-controlling the changes that are introduced over time. In its turn, this approach makes it easier to keep your workload environments compliant and saves ton of time in troubleshooting, development and auditing your resources
In this post, we will look into the necessity of child resources in Azure and how Bicep language simplifies their management and declaration as a code.
why azure bicep child resources?
There are a number of scenarios where it makes perfect sense to declare resources within the context of their parent. For example; storage blob containers could not be declared and used without a parent storage account.
In addition to Blob containers, there are many other child resource types in Azure like:
Virtual network subnets
SQL databases
Azure Cosmos DB containers
SQL databases
VM extensions
How could you define child resources?
Unsurprisingly, there is more than one way to define Azure Bicep child resources. Each approach will depend on a specific use case that you or your team is looking forward to delivering.
Further we will use the example of a storage account resource to describe different options of child resource declarations. This will make it easier to describe the concepts and available options to you. However, these concepts could be easily used on other Azure services like VMs and VNets that do have child resources too.
Option-1 : Child resource created with reference to parent
Our first option is declaring a child Blob container resource as a separate independent resource with a reference to a parent resource. Like, it is illustrated on the example screen-shot from the Learn-Bicep repo.
For this option to work, we would need to declare an Azure Storage Blob service too. Let’s look into how it could be done while considering a second option.
Option-2 : Including a child resource in the declaration
Our second option is declaring a Storage Blob service resource as a separate independent resource with a reference to a parent Storage Account resource. Then it has an inner declaration for a container child resources within the Storage Blob service.
Let’s look at the example screen-shot from the Learn-Bicep repo.
This option might be an ideal approach if you have few child resources in your declaration. However, it would not be the most efficient one to use, if the number of child resources you are required to deploy is in dozens, hundreds or even thousands.
Option-3 : Automation and looping with enumeration π
The final option will serve you well, if you have 100s of pre-defined containers that should be deployed into your Azure environment.
By leveraging the “iterative loops” in Bicep we can easily iterate over these containers while creating them in a compact and repeatable manner, like in the following screen-shot from the repo code.

Are you looking for a simpler, more efficient way to author infrastructure resources in Azure?
Azure Bicep First Look course
If so, youβre in luck. Azure Bicep is here to help. Bicep is a new domain-specific language (DSL) for deploying resources in Azure. Itβs also a much cleaner, more concise language than ARM JSONβcloud admins and DevOps professionals, rejoice!
Every seasoned IT professional knows that sensitive information should not be exposed as a clear text on any code. This is especially true for infrastructure-as-code (aka, IaC) scenarios where passwords and keys are part of the deployment.
One way to stay compliant in accomplishing this goal is the integration of an Azure Key Vault service into your deployment code. This Azure security service is primarily intended to store sensitive information like password, keys, certificates, connections, etc.
In this post, we will look into two different ways how we could integrate Azure Key Vault services in our Azure Bicep code.
Option – 1: Using getSecret() function
Our first option is to delegate this important work to a getSecret() function. This option could be used with an existing Azure Key Vault resource that is declared in your Azure Bicep code.
Let’s look into an example where an existing Azure Key Vault service is referenced to provide administrative password for SQL server deployment.
Deploying Azure SQL instance with Azure Key Vault
This sample Bicep code is using sqldb.bicep file as a module, where parameters; such as sqlServerName and adminLogin are passed through with a secret name of ExamplePassword.
The ExamplePassword secret name should be already set and ready in the referenced Key Vault service above. Here is the view of this secret on Azure portal.
Azure Key Vault with secretes in portal
Let’s have a quick view into the sqldb.bicep file, as it is referenced in the main Bicep file.
sqldb.bicep file
Now, let’s deploy these resources with a secret value from Key Vault resource that has a secret name ExamplePassword.
What happened? I am getting an error on my first deployment execution π
Error on deploying Bicep code with SQL server provisioning
Upon carefully analyzing error, I see the following reason for this error:
At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.”,”details”:[{“code”:”RegionDoesNotAllowProvisioning”,”message”:”Location ‘East US 2’ is not accepting creation of new Windows Azure SQL Database servers at this time.
Azure deployment error
Based on the error message, we change the location to eastus and re-run the script. Now, we got the following positive result in console and portal:
Deployment results in Azure Portal RG
Next, we will attempt to login into a SQL Server instance. A successful login will look like the following screen:
Successful login into the SQL instance
Important Note:
If you are getting an error during the login then try to check the following steps:
adminLogin name is entered correctly
your IP address is added to the SQL server firewall rules
grab a cup of coffee and check back in 5 minutes
Description of a typical login error into a SQL server instance is provided below. I checked the firewall rules and made a cup of coffee => before getting a successful log-in π
Requires your location IP activation
Option -2: Referencing as a secretName in parameter
The second option is pretty straightforward, if you have already used it on ARM template deployments.
We just need to reference Azure Key Vault secret like in the following example:
Using a parameter file and referencing the Key Vault secretName will do the trick in extracting the value and provisioning your resource.
Let’s run the bicep file that deploys multiple RGs and an Azure VM that uses VMPassword secret.
Running deployment with Bicep parameter file
A successful deployment provisions following RG with the VM resources:
Next, we should smoke test our deployment by locating the resource group “rg-demo-vm-1116” and using deployment parameters to RDP into Windows server:
Finally, we are able to see that secret and admin user name pair worked as expected
Azure VM deployed using Key Vault secret
Summary
In this post, we looked into two available options that harden our infrastructure code by removing hard-coded sensitive information and replacing it with Azure Key Vault reference. Thus, avoiding any potential leaks of passwords, secrets, etc.
IMHO, first option is better than the later one, because it does not expose subscription id and other small details.
I am very excited to see you all in the next Omaha Azure User Group meetup. This time we will speak about the latest advancements and use cases you could apply in your Azure resource authoring toolkit.
