In this article, we will show you how to use variables in a Bicep template. Variables are a great way to keep your templates organized and easy to edit.
They allow you to insert specific information into your templates, such as the name of your resources and more. Let’s get started!
Declare a Variable
To declare a variable in a Bicep template, we are using the var keyword, the variable’s name, and the value of the variable.
In the example below, I’m declaring a variable called storageaccount with the name ntweeklystr0001
var storageaccountname = 'ntweeklystr0001'
After declaring the variable in the template, I can start using it and reference it. You can see the end-to-end code in action in the template below. The first line declares the variable, and it is used in line number three.
Template
var storageaccountname = 'ntweeklystr0001'
resource storageAccount 'Microsoft.Storage/storageAccounts@2019-06-01' = {
name: storageaccountname
location: resourceGroup().location
sku: {
name: 'Standard_LRS'
}
kind: 'StorageV2'
properties: {
accessTier: 'Hot'
}
}
Use Parameters
We can also use parameters with Bicep using the following example. When using parameters, we need to define the type (string, int or bool) and set a default value (optional)
perm storageaccountname string = 'ntweeklystr0001'
Parameters are excellent when passing values to a Bicep template or using a template file.
