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.$concat doesn't do what I think you think it does; it does not concatenate the items in a list to form a string, it concatenates two lists to form another list. You need to use $join instead. I have a worked example at http://thecloudwoman.com/2017/05/how-to-use-a-terraform …944 6 21 54. 1. Unfortunately most languages' map/hash/dict map function will merge one level deep, and not recursively. You would have to code a custom lambda for this. I threw about ten minutes at it, and I think TF's current DSL is not robust enough to allow coding a deep/recursive map merge.
Because function arguments are ordered, this only works with sequence types (lists and tuples) and not for maps. However, if lexical sorting by key is sufficient for what you need -- which it sounds like should be true in your case where the different maps/objects have distinct keys/attributes -- you can use the values function to succinctly extract a list of the values from a map:I want to merge these JSONs into one under keys in Terraform.

Explore the practicalities of Terraform's concat function, a key tool for combining lists in your configurations. This article delves into its syntax, usage, and real-world applications, providing essential tips for efficient infrastructure coding.In Terraform, more complex string concatenation scenarios can be achieved using the join function. This function is quite flexible and allows you to concatenate a list of strings using a separator. To use it in this case, you can convert the string parts you want to concatenate into a list and then use join with a dot separator.
The Terraform language has a set of operators for both arithmetic and logic, which are similar to operators in programming languages such as JavaScript or Ruby. When multiple operators are used together in an expression, they are evaluated in the following order of operations: !, - (multiplication by -1) *, /, %. +, - (subtraction) >, >=, <, <=.The slice function extracts some consecutive elements from within a list.Learn how to use the concat() function in terraform to dynamically generate a list of objects or strings based on conditions.
