terraform: Using for_each over tuples

2 min read

Let's imagine we have the following data structure:

locals {
  queries = [
    {
      query  = "SELECT version()"
      engine = "postgresql"
    },
    {
      query  = "SELECT * FROM v$version"
      engine = "oracle"
    },
    (...)
  ]
}

If we want to use just some of the items on a resource we can use for_each through the resulting array of filtering the objects using a for:

for_each = [ for item in local.queries: item if item.engine == "postgresql" ]
