The `packer inspect` command takes a template and outputs the various
|
|
components a template defines. This can help you quickly learn about a
|
|
template without having to dive into the JSON itself. The command will tell
|
|
you things like what variables a template accepts, the builders it defines,
|
|
the provisioners it defines and the order they'll run, and more.

# `inspect` Command
|
|
|
|
The `packer inspect` command takes a template and outputs the various components
|
|
a template defines. This can help you quickly learn about a template without
|
|
having to dive into the JSON itself. The command will tell you things like what
|
|
variables a template accepts, the builders it defines, the provisioners it
|
|
defines and the order they'll run, and more.
|
|
|
|
This command is extra useful when used with
|
|
[machine-readable output](/docs/commands/index.html) enabled. The
|
|
command outputs the components in a way that is parseable by machines.
|
|
|
|
The command doesn't validate the actual configuration of the various components
|
|
(that is what the `validate` command is for), but it will validate the syntax of
|
|
your template by necessity.
|
|
|
|
## Usage Example
|
|
|
|
Given a basic template, here is an example of what the output might look like:
|
|
|
|
``` text
|
|
$ packer inspect template.json
|
|
Variables and their defaults:
|
|
|
|
aws_access_key =
|
|
aws_secret_key =
|
|
|
|
Builders:
|
|
|
|
amazon-ebs
|
|
amazon-instance
|
|
virtualbox-iso
|
|
|
|
Provisioners:
|
|
|
|
shell
|
|
```
