I am trying to pass a variable dynamically from the Yaml file to my bicep file, but no luck.

Please note overrideParameters: '-capital_env $(environment) based on this.

I also tried

param capital_env=''

and

param capital_env

and

param capital_env string

in my bicepparam file but no luck.

I also tried overrideParameters: '-capital_env DEV' in my yaml file, but this one also did not work.

I have this yaml file:

parameters:
- name: environment
  displayName: 'Environment'
  type: string
  default: 'DEV'
  values:
  - DEV
  - TST
  - PRD

trigger: none
pr: none

stages:
- stage: Deploy
  displayName: 'Deploy to $(environment)'
  jobs:
  - job: DeployDev
    displayName: 'Deploy to Development Environment'
    condition: eq('${{ parameters.environment }}', 'DEV')
    pool:
      name: 'PartnerPortal'
    variables:
      azureServiceConnection: 'AzON-TST'
      resourceGroupName: 'rgname'
      location: 'australiaeast'
      templateFile: '.InfrastructureDEVmainStorageAccountCreation.bicep'
      parametersFile: '.InfrastructureDEVmainStorageAccountCreation.bicepparam'
    steps:
    - script: |
        echo "Listing files in $(System.DefaultWorkingDirectory)"
        dir $(System.DefaultWorkingDirectory)
        echo "Listing files in $(System.DefaultWorkingDirectory)InfrastructureDEV"
        dir $(System.DefaultWorkingDirectory)InfrastructureDEV
      displayName: 'List files in working directory'
    - script: |
        echo "Current PATH: $env:Path"
        az --version
      displayName: 'Verify Azure CLI Installation'
    - task: AzureResourceManagerTemplateDeployment@3
      inputs:
        deploymentScope: 'Resource Group'
        azureSubscription: '7c0513a'
        ConnectedServiceName: 'AzON-TST'
        resourceGroupName: $(resourceGroupName)
        location: $(location)
        templateLocation: 'Linked artifact'
        csmFile: '$(templateFile)'
        csmParametersFile: '$(parametersFile)'
        overrideParameters: '-capital_env $(environment)'
      displayName: 'Deploy ARM Template to DEV'

I have this bicepparamter file:

using 'mainStorageAccountCreation.bicep'
param capital_env='dfd'
param lower_env = toLower(capital_env)
param encryptionScopeName = 'defaultEncryptionScope'
param publicNetworkAccessLappFapp = 'Disabled'
param publicNetworkAccessApp = 'Enabled'
param ipWhitelist= [
  '203....' //my IP
]
param storageAccountsApp = [
  'uwasydstapartp${lower_env}'
]

param storageAccountsfapplapp = [
  'uwasydstapartptla${lower_env}'
  'uwasydstapartptli${lower_env}'
]

and this my bicep file

param location string = resourceGroup().location
param capital_env string
param lower_env string = toLower(capital_env)
targetScope = 'resourceGroup'
param encryptionScopeName string
param publicNetworkAccessApp string
param publicNetworkAccessLappFapp string
param storageAccountsApp array
param storageAccountsfapplapp array
param ipWhitelist array
module storageapp '../modules/StorageAccountApp.bicep' = [for storageName in storageAccountsApp: {
  name: storageName
  params: {
    location: location
    storagename: storageName
    encryptionScopeName: encryptionScopeName
    publicNetworkAccessApp: publicNetworkAccessApp
    ipWhitelist:ipWhitelist
  }
}]



module storageappfapplapp '../modules/StorageAccountLappFapp.bicep' = [for storageName in storageAccountsfapplapp: {
  name: storageName
  params: {
    location: location
    storagename: storageName
    encryptionScopeName: encryptionScopeName
    publicNetworkAccessLappFapp: publicNetworkAccessLappFapp
  }
}]

the module for creating the storage account

param storagename string
param location string
param encryptionScopeName string
param publicNetworkAccessApp string
param ipWhitelist array // Array of IP addresses to whitelist
resource storageAccount 'Microsoft.Storage/storageAccounts@2023-01-01' = {

    //dnsEndpointType: 'string'
    encryption: {
     
      keySource: 'Microsoft.Storage' //Microsoft-managed keys
      
      requireInfrastructureEncryption: false
      services: {
        blob: {

         // keyType: 'Account'
        }
        file: {
          enabled: true
         // keyType: 'Account'
        }
        queue: {
          enabled: true
         // keyType: 'Account'
        }
        table: {
          enabled: true
         // keyType: 'Account'
        }
      }
    }
    
    isHnsEnabled: false
    isLocalUserEnabled: false
    isNfsV3Enabled: false
    isSftpEnabled: false
    
    minimumTlsVersion: 'TLS1_2'
    networkAcls: {
      bypass: 'AzureServices'
      ipRules: [
        for ip in ipWhitelist: {
          action: 'Allow'
          value: ip
        }
      ]
      defaultAction: 'Deny'
    }
    publicNetworkAccess: publicNetworkAccessApp
  
   }
}

resource encryptionScope 'Microsoft.Storage/storageAccounts/encryptionScopes@2022-09-01' = {
  name: encryptionScopeName
  parent: storageAccount
  properties: {
    source: 'Microsoft.Storage'
  }
}

I am not able to pass capital_env from the yaml to bicepparam successfully, what changes I may need to do to fix this?

I am expecting to pass the capital_env to my bicepparemter file.
