Naming in Terraform and Bicep

Build the name from variables so one module produces the right name in every environment. The 22-character limit is enforced in the expression.

Terraform

locals {
  data_explorer_cluster_name = substr(lower("dec${var.workload}${var.environment}${var.region}001"), 0, 22)
}

Bicep

var dataExplorerClusterName = take(toLower('dec${workload}${environment}${region}001'), 22)
