Affected Resource(s)

Please list the resources as a list, for example:

• ibm_is_region

Making the name argument optional will provide 2 use cases.

1. Being able to query the current region configured from the environment.

data "ibm_is_region" "current" {}

resource ibm_database standalone {
  ... 
  region = data.ibm_is_region.current.name
}

2. In modules needing providers.

Example of calling the module

provider "ibm" {
  region = "us-east"
  alias = "east"
}

provider "ibm" {
  region = "us-south"
  alias  = "south"
}

module "database_with_replica" {
    providers {
       ibm.primary = "ibm.east
       ibm.secondary = "ibm.south"
  }
}

Example of the module main.tf

provider "ibm" {
  alias = "primary"
}
provider "ibm" {
  alias = "secondary"
}

data ibm_is_region primary {
   provider = ibm.primary
}
data ibm_is_region secondary {
  provider = ibm.secondary
}

resource ibm_database primary {
   ...
   region = data.ibm_is_region.primary.name
}
resource ibm_database replica {
  ...
  region = data.ibm_is_region.secondary.naem
}
