• if keyword
  • define a bool param and if needed, then only deploy the resource
• check using operators
  • ==
  • better to create a [[202407191900 Bicep variables|Bicep variables]] for the evaluation

Example

[[202404061212 Azure Resources|ARM]] evaluates the property expressions before the conditionals on the resources.

resource auditingSettings 'Microsoft.Sql/servers/auditingSettings@2021-11-01-preview' = if (auditingEnabled) {
  parent: server
  name: 'default'
  properties: {
    state: 'Enabled'
    storageEndpoint: environmentName == 'Production' ? auditStorageAccount.properties.primaryEndpoints.blob : ''
    storageAccountAccessKey: environmentName == 'Production' ? listKeys(auditStorageAccount.id, auditStorageAccount.apiVersion).keys[0].value : ''
  }
}
