Terraform concatenate lists

Hi @amanohar,. The == operator can only return true when the two operands have identical types, and the type of [] alone (without any further type conversions) is an empty tuple rather than a list of strings and so I expect that comparison is always returning false.. If your goal is to use different behavior when the list is empty, test the length of the list instead:.

Terraform attempts to select a result type that all of the arguments can convert to, so mixing argument types may produce surprising results due to Terraform's automatic type conversion rules: > coalesce(1, "hello") ...value = concat(var.list1, var.list2, var.list3) In this example, list1, list2, and list3 are variables holding different lists. The concat function is used in the combined_list output to merge all three lists into one. When you run terraform apply, the combined_list output will display the combined list:

Did you know?

Your arguments to concat have a typo, you need to supply multiple lists which are to be concatenated, while you have supplied a single list (this however would probably be a valid argument to flatten). Without a more complete example, I’m not sure about what the other errors mean.Concatenate two lists in Terraform 0.12 - concat() 4. Concatenate variables in terraform V0.12. 3.

How to merge tuples into pairs and then turn into a string? 1.A second option is to simplify and use a second map, since there's a 1:1 mapping between uid and instance_id. As the key would be the same in each case (uid), I could have one map which was { uid = vols_list } and a second which is { uid = instance_id } , and then just use one as an index into the other, i.e. for_each = var.instances_vols.Is there a way to use the below list in a for loop and add in the target_groups? I am trying to use the prefix with target_groups variable in a for-loop. I have tested also for_each. The target_groups expects the list format but the for_each does not give that expected result.

The list arguments are iterated together in order by index, while the non-list arguments are used repeatedly for each iteration. The format string is evaluated once per element of the list arguments. ExamplesThe list function is no longer available. Prior to Terraform v0.12 it was the only available syntax for writing a literal list inside an expression, but Terraform v0.12 introduced a new first-class syntax.

If the configuration and the states were combined, this should likely show no changes.0. Terraform is (sadly) not a programming language, so it's not easy (or possible) to convert any pseudo-code to HCL.
