Description

Terraform has a filebase64 built-in function, but it doesn't seem like Packer supports it.

For what it's worth, if I try to use the file function on something that isn't valid UTF-8, Packer generates this error, which seems to imply the filebase64 function should exist:

Call to function "file" failed: contents of
*** are not valid UTF-8; use the
filebase64 function to obtain the Base64 encoded contents or the other file
functions (e.g. filemd5, filesha256) to obtain file hashing results instead.

Use Case(s)

Loading a binary file and embedding a base64 encoding of it into a cloud-init config, for example.
