Using the split Function. The split function is used to break a string into a list of substrings based on a specified delimiter. In our case, we want to split the string using a comma and space as the delimiter: my_var = "foo, bar, xid, b59".toset(concat(list_a, list_b)) ... The difference is only in the method Terraform takes to calculate the result. In the first case it will first construct a new list which is the concatenation of list_a and list_b, and then convert that result to a set.Any help on how to concat the two outputs and the custom list into one will be appreciated. I'm thinking I may have to create a list from the two outputs first, then concat the two lists together, but not entirely sure. Can I do it in one command?

I'm new to terraform so struggling on this. template = <<EOF. template = <<EOF. user_data = "${data.template_file.user_data1.rendered}"Related Functions. join performs the opposite operation: producing a string joining together a list of strings with a given separator. The split function produces a list by dividing a given string at all occurrences of a given separator.The specification string uses the same syntax as format. The given values can be a mixture of list and non-list arguments. Any given lists must be the same length, which decides the length of the resulting list.tomap Function. tomap converts its argument to a map value. Explicit type conversions are rarely necessary in Terraform because it will convert types automatically where required. Use the explicit type conversion functions only to normalize types returned in module outputs.When using the -var parameter, you should ensure that what you are passing into it will be properly interpreted by HCL. If the variable you are trying to pass in is a map, then it needs to be parse-able as a map.

I think mount_point would need to be a map to utilize the merge function here. As it is, I notice that both types are list as primitives, so maybe iterate through one list and then access the element maps of the first variable and elements of the second variable by index.
