variable block

This topic provides reference information about the variable block.

Description

The variable and input-variable blocks define variables within your Packer configuration. You cannot use the input-variable block in another input-variable block. We recommend using the locals to nest variables instead.

@include 'from-1.5/variables/foo-block.mdx'

Default value

If a default value is set, the variable is optional. Otherwise, the variable must be set.

@include 'from-1.5/variables/assignment.mdx'

@include 'from-1.5/variables/custom-validation.mdx'

Example of a variable assignment from a file:

@include 'from-1.5/variables/foo-pkrvar.mdx'

@include 'from-1.5/variables/must-be-set.mdx'

@include 'from-1.5/variables/sensitive.mdx'
