# Image script plugin

This plugin gives the possibility to the user to execute commands.

Plugin is defined in the manifest file, plugin section with:

    "image_commands": {
        "commands": [ [ "touch", "/var/www/index.html" ]],
    }

The *commands* element is an array of commands. Each command is an array describing the executable and its arguments.

If you need shell expansion of wildcards, like __\*__, just put the entire command as a single entry:

    "image_commands": {
        "commands": [ [ "rm -f /tmp/*" ]],
    }

Command is executed in current context. It is possible to use variables to access the image or execute chroot commands in the image.

Available variables are:
  {root} : image mount point (to copy files for example or chroot commands)

Example:

    [[ "touch", "{root}/var/www/hello" ],
    [ "/usr/sbin/chroot", "{root}", "touch", "/var/www/hello"]]
