A packer provisioner that works much like the typical packer 'shell' provisioner, except that it works on the host machine (i.e. the packer build machine) instead of the guest/remote environment. The rationale for this is to have an automated step to run something like serverspec tests against a packer built machine.

Note: most of this provisioner takes common work from the existing shell provisioner in packer: https://github.com/mitchellh/packer/tree/master/provisioner/shell

Usage of this provisioner is similar to the shell provisioner. Except, the type is host-command and fields are either command or commands. For example:

{
  "type": "host-command",
  "command": "ls -la"
}

Or multiple commands, run sequentially:

{
  "type": "host-command",
  "commands": [
    "whoami",
    "pwd",
    "/path/to/script.sh"
  ]
}

Both command and commands are treated as configuration templates. The full list of available options for this provisioner are:

• command: A string of the command to run
• commands: A list of strings of commands to run. These are run sequentially.
• environment_vars: A list of strings for environment variables to set before running a command. These values must be valid syntax (i.e. "foo=bar" or "baz=")
• execute_command: The template for how a command is run. This is a configuration template, and by default is "{{ .Command }}". The template variable "{{ .Command }}" must be present.

You will need Go installed, then run make, which will perform a clean, deps, and build.

To run the tests: make test
