packer: Check the syntax of a Packer image config.
$ packer validate ${path-to-config-json}
try on your machine

The command "packer validate ${path-to-config-json}" is used to validate a Packer configuration JSON file.

Here is a breakdown of the command:

  • "packer": Refers to the Packer command-line tool.
  • "validate": This is the subcommand for validating Packer configuration files.
  • "${path-to-config-json}": This is a placeholder representing the actual file path of the Packer configuration JSON file you want to validate. You need to replace it with the correct path to your JSON file.

When you run this command with the correct path to your Packer configuration JSON file, Packer will check the file for syntax errors, validate the configuration against Packer's schema, and provide feedback on any issues or errors encountered. This validation helps ensure that your Packer configuration is correct before attempting to build images or perform other operations.
