💪Azure Bicep: working with Parameters — Best practices

When and how should you use parameters in your Azure Bicep templates.

In Azure Bicep, the new domain-specific language (DSL) to declarative deploy Azure resources, we define parameters just as we did in ARM templates. There are a few differences in the syntax we should consider.

Azure Bicep — Parameters

Parameters in Azure Bicep

Parameters are input values we define in the Bicep template. These values can be passed on either inline during the deployment operation or referenced from a Parameters file.

Declaring parameters in Azure Bicep

You need to provide a name and type for each parameter in your Bicep template. The code below shows how to declare parameters:

param demoString string
param demoInt int
param demoBool bool
param demoObject object
param demoArray array

A parameter can’t have the same name as a variable, module, or resource. Don’t overuse parameters. Parameters are often utilized when we need to pass on values that need to vary for different deployments.

For example, when you create a storage account, you need to provide the SKU and type; you could leverage parameters.
