NAME

Chef::Knife::Cmd - A small wrapper around the Chef 'knife' command line utility

SYNOPSIS

use Chef::Knife::Cmd;

my $knife = Chef::Knife::Cmd->new(
    verbose   => 0,           # if true, tee output to STDOUT; default is false
    logfile   => 'knife.log',
    print_cmd => 1,
    format    => 'json',      # add '--format json' to all knife commands
);

# All methods below
# - return the output of the cmd as a string
# - return a hashref of the decoded json output when '--format json' is used

# knife bootstrap
$knife->bootstrap($fqdn, %options);

# knife client
$knife->client->delete($client, %options);

# knife ec2
$knife->ec2->server->list(%options);
$knife->ec2->server->create(%options);
$knife->ec2->server->delete(\@nodes, %options);

# knife node
$knife->node->show($node, %options);
$knife->node->list($node, %options);
$knife->node->create($node, %options);
$knife->node->delete($node, %options);
$knife->node->flip($node, $environment, %options);
$knife->node->run_list->add($node, \@entries, %options);

# knife vault commands
# hint: use $knife->vault->item() instead of $knife->vault->show()
$knife->vault->create($vault, $item, $values, %options);
$knife->vault->update($vault, $item, $values, %options);
$knife->vault->show($vault, $item_name, %options);

DESCRIPTION

This module is a small wrapper around the Chef 'knife' command line utility.

It would be awesome if this module used the Chef server API, but this module is not that awesome.

Some things to know about this module:

• Return vaules

  All commands return the output of the knife command.

• Logging

  All knife cmd output is logged to a logfile for later analysis. This allows you to provide verbose logging to users while not cluttering their terminal with tons of output.

• Tee output to STDOUT

  Instead of waiting for an hour for a knife command to finish, you can view output from the knife command in real time as it happens. This happens when the 'verbose' attribute is true.

• Exceptions

  If a knife command fails, this module will throw an exception.

• No need to mess about with string manipulation

  Yay.

ABOUT THE NAME

I didn't name this Chef::Knife because I'm hoping someone someday will write a real Chef::Knife module which uses the Chef server API.
