How to provided multiple permission in bicep for accesspolicy

Question

This is the bicep format for table access policy

resource symbolicname 'Microsoft.Storage/storageAccounts/tableServices/tables@2023-01-01' = {
  name: 'string'
  parent: resourceSymbolicName
  properties: {
    signedIdentifiers: [
      {
        accessPolicy: {
          expiryTime: 'string'
          permission: 'string'
          startTime: 'string'
        }
        id: 'string'
      }
    ]
  }
}

permission	List of abbreviated permissions. Supported permission values include 'r','a','u','d'	string (required)

so i need to give permission of read and update. but the expected vaule is string and i am not sure how to provide muliple access permission

Answer 1

There are very few official sample codes about this, I find an community one, it is about fileshares, but has the same pattern for tables

resource share 'Microsoft.Storage/storageAccounts/fileServices/shares@2022-09-01' = {
  name: 'fileshare'
  parent: fileService
  properties: {
    shareQuota: 100 //This is GB
    enabledProtocols: 'SMB'
    signedIdentifiers: [
      {
        accessPolicy: {
          startTime: '2023-03-17T08:49:37.0000000Z'
          expiryTime: '2028-03-17T08:49:37.0000000Z'
          permission: 'rcl' //read, create, list
        }
        id: 'readcreatelist'
      }
    ]
  }
}

Just change the sample permission 'rcl' to 'raud'
