base64gzip Function

base64gzip compresses a string with gzip and then encodes the result in Base64 encoding.

Terraform uses the "standard" Base64 alphabet as defined in RFC 4648 section 4.

Strings in the Terraform language are sequences of unicode characters rather than bytes, so this function will first encode the characters from the string as UTF-8, then apply gzip compression, and then finally apply Base64 encoding.

While we do not recommend manipulating large, raw binary data in the Terraform language, this function can be used to compress reasonably sized text strings generated within the Terraform language. For example, the result of this function can be used to create a compressed object in Amazon S3 as part of an S3 website.
