# Built-in Blocks
|
|
|
|
`@include 'from-1.5/beta-hcl2-note.mdx'`
|
|
|
|
The Packer - HCL2 language includes a number of built-in blocks that you can
|
|
use. A block is a container for configuration.
|
|
|
|
Blocks can be defined in multiple files and `packer build folder` will build
|
|
using solely the files from a directory named `folder`.
|
|
|
|
Packer does not support user-defined blocks and so only the blocks built in to
|
|
the language are available for use. The navigation for this section includes a
|
|
list of all of the available built-in HCL2 blocks.
|
|
|
|
