#provision_commands_wrapper(image_name) ⇒ Array<String>

A wrapper around provision_commands that allows for extra commands to be added for a specific OS version(i.e EL 8)

Parameters:

  • image_name (String) —

    The name of the OS image being provisioned.

Returns:

  • (Array<String>) —

    An array of shell commands to be run on the provisioned nodes to set up the necessary environment for running the Puppet manifest, including any additional commands needed for specific OS versions.
