replace Function

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

replace searches a given string for another given substring, and replaces each occurrence with a given replacement string.

replace(string, substring, replacement)

If substring is wrapped in forward slashes, it is treated as a regular expression; the syntax conforms to the re2 regular expression syntax syntax. If using a regular expression for the substring argument, the replacement string can incorporate captured strings from the input by using an $n sequence, where n is the index or name of a capture group.

Examples

> replace("1 + 2 + 3", "+", "-")
1 - 2 - 3

> replace("hello world", "/w.*d/", "everybody")
hello everybody
