# About Builds

Builds are instances of `packer build` being run within Terraform Enterprise. Every
build belongs to a build configuration.

__Build configurations__ represent a set of Packer configuration versions and
builds run. It is used as a namespace within Terraform Enterprise, Packer commands and URLs. Packer
configuration sent to Terraform Enterprise are stored and versioned under
these build configurations.

These __versions__ of Packer configuration can contain:

- The Packer template, a JSON file which define one or
more builds by configuring the various components of Packer
- Any provisioning scripts or packages used by the template
- Applications that use the build as part of the pipeline and merged into the version prior to running Packer on it

When a new version of Packer configuration and associated
scripts from GitHub or `packer push` is received, it automatically starts a new
Packer build. That Packer build runs in an isolated machine environment with the contents
of that version available to it.

You can be alerted of build events with [Build Notifications](/docs/enterprise/packer/builds/notifications.html).
