Description

Slider application package allows defining of arbitrary commands. However, there is no way to execute these arbitrary commands using the Slider command line. A basic approach can be as follows:

• App developer defines a custom command say "COMMAND" and a python function is mapped to this command in the same way as "START" or "INSTALL".
• Using Slider-Agent the command can be issued against specific containers identified by the container id
• While issuing commands, optional properties (name-value pairs) may be provided
• Once command is issued a command id is returned that can be used to retrieve the command result
• Command execution or the result is not persisted by Slider - so it is a best effort execution
