Strings and Templates. String literals are the most complex kind of literal expression in Terraform, and also the most commonly used. Terraform supports both a quoted syntax and a "heredoc" syntax for strings. Both of these syntaxes support template sequences for interpolating values and manipulating text.Let’s start with the fundamentals. In Terraform, variables are defined in the variables.tf file, and their values can be assigned in terraform.tfvars or directly in the resource declaration. Mixing strings and variables is essential for dynamic resource configuration.concat(keycloak_user.user, var.keycloak_user_ext) Has two problems: keycloak_user.user is (essentially) a map of 4 keycloak_user resources (since you defined it with the for_each); and; var.keycloak_user_ext is just a simple string (as far as Terraform knows).To convert a string to a list in Terraform, you can follow these steps: 1. 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".I'm going to lock this issue because it has been closed for 30 days ⏳.

Only the primitive types (string, number, and bool) and null ...I would say rather concatenating at resource level use the locals first define a variable in locals and then you can utilize it at resource level. Locals declaration. rds_instance_name = "${var.env}-${var.rds_name}" Resource Level declaration. count = var.db_create ? 1 : 0.1. To concatenate variable with the string, use this syntax instead of join () : foo = "string-${var.bar}-a-string". But if you don't want to use a variable for string concatenation, you can use such syntax: foo = var.bar. edited May 5, 2021 at 17:04. answered Jan 2, 2020 at 10:31.Related Functions. join performs the opposite operation: producing a string joining together a list of strings with a given separator.May 27, 2020 · I want my modules to be able to export their own list of roles like roles = [ { role = "roles/viewer" members = ["user: [email protected] "] } ] And then be able to merge these things together to getWhen it comes to catering, having a price list is essential for ensuring that you are getting the most out of your menu.
