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 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:
$ packer inspect template.json Variables and their defaults: aws_access_key = aws_secret_key = Builders: amazon-ebs amazon-instance virtualbox-iso Provisioners: shell
