Azure Bicep Templates

Bicep Templates in Azure

Bicep is the modern, cleaner alternative to ARM JSON templates. It’s declarative, easier to read, and natively compiles to ARM templates.

  metadata: {
    description: 'Unique name for the storage account.'
  }
}

param location string = 'eastus' {

    'Standard_ZRS'
    'Premium_LRS'
  ]
