Instance Method Details

#build_hosts_preserved_reproducing_command(command, new_hostsfile) ⇒ String

provides a new version of the command given, edited for re-use with a preserved host. It does this by swapping the hosts file out for the new_hostsfile argument and removing any previously set provisioning flags that it finds (we add :provision => false in the new_hostsfile itself).

Parameters:

  • command (String) —

    Command line parameters to edit.

  • new_hostsfile (String) —

    Path to the new hosts file to use.

Returns:

  • (String) —

    The command line parameters edited for re-use

#preserve_hosts_file ⇒ Object

Sets aside the current hosts file for re-use with the –no-provision flag. This is originally intended for use on a successful tests where the hosts are preserved (the –preserve-hosts option is set accordingly). It copies the current hosts file to the log directory, and rewrites the SUT names to match their names during the finishing run.

Returns:

  • nil

#print_command_line(log_level = :debug) ⇒ Object

Note:

Re-use of already provisioned SUTs has been tested against the vmpooler & vagrant boxes. Fusion doesn’t need this, as it has no cleanup steps. Docker is untested at this time. Please contact @electrical or the Puppet QE Team for more info, or for requests to support this.

Prints the command line that can be called to reproduce this run (assuming the environment is the same)

Examples:

Print pertinent env vars using error level reporting (red)

print_command_line :error

Parameters:

  • log_level (Symbol) (defaults to: :debug) —

    The log level (coloring) to print the message at

Returns:

  • nil
