Local

Local resources allow you to create, temporary computed variables that can be used within your config. For example, if you wanted to compute a value that was based on the attribute of another resource you could use a local.

resource "config" "myconfig1" {
  db_connection_string = variable.connection_string 
}

local "conn" {
  value = resource.config.myconfig1.db_connection_string == "abc" ? "localhost" : resource.config.myconfig1.db_connection_string
}

resource "config" "myconfig2" {
  db_connection_string = local.conn
}

Unlike variables local variables are part of the graph and can contain references to other resources.
