Note: This page is about Terraform 0.12 and later. For Terraform 0.11 and earlier, see 0.11 Configuration Language: Interpolation Syntax.

join produces a string by concatenating together all elements of a given list of strings with the given delimiter.

join(separator, list)

» Examples

> join(", ", ["foo", "bar", "baz"])
foo, bar, baz
> join(", ", ["foo"])
foo

split performs the opposite operation: producing a list by separating a single string using a given delimiter.
