Encoding Functions

This section will cover the different encoding functions available in Terraform. You can use them to encode the files created in your own configuration or decode a given file in a specific scheme.

The examples used in the section will be available with the filename 8. encoding-functions.txt in the GitHub link provided at the start of this chapter.

The base64encode() and base64decode() Functions

These functions can encode a given string in base64 format, decode a base64 encoded string, and return the original string.

Here is an example:

$ base64encode("This is a string")

> "VGhpcyBpcyBhIHN0cmluZw=="

$ base64decode("VGhpcyBpcyBhIHN0cmluZw==")

> "This is a string"

The base64gzip() Function

This function compresses a string with gzip and then encodes it with base64 encoding.

Here is an example:

$ base64gzip("This is a string")
