      az_sa_regex_pattern: "(?<=storageAccounts\/)(.*)"
      az_sa_id_test: "/subscriptions/s1/resourceGroups/rgroupName/providers
      /Microsoft.Storage/storageAccounts/storageAccountNameDef1"
      sa_rg_name_expected: "rgroupName"
      sa_name_expected: "storageAccountNameDef1"
  - name: set results
    set_fact:
