NAME

Csistck – Perl system consistency check framework

SYNOPSIS

    use Csistck;
    
    for my $host (qw/a b/) {
        host $host => role('test');
    }

    host 'c' => role('test');
    
    role 'test' => 
        template(".files/test.tt", "/tmp/test", { text => "Some text here" }),
        permission("/tmp/test*", mode => '0777', uid => 100, gid => 100);
    
    check;

The script can then be called directly, using command line arguements below

DESCRIPTION

Csistck is a small Perl framework for writing scripts to maintain system configuration and consistency. The focus of csistck is to stay lightweight, simple, and flexible.

EXTENDING ROLES

Roles can be defined using the role keyword syntax, however a more flexible method is to extend a new object from Csistck::Role:

    use Csistck;
    use base 'Csistck::Role';

    sub defaults {
        my $self = shift;
        $self->{config} = '/etc/example.conf';
    }

    sub tests {
        my $self = shift;
        $self->add(pkg({
            dpkg => 'test-server',
            pkg_info => 'net-test'
        }),
        template('files/example.conf', $self->{config}, { example => $self });
    }

    1;

See Csistck::Role for information on extending roles

METHODS

option($name, $value)

    Set package type
  • domain_name [string]
    Set default domain name to append to hosts

host($hostname, [@tests]);

Append test or array of tests to host definition.

    host 'hostname' => noop(1), noop(1);
    host 'hostname' => noop(0);

Returns a reference to the host object.

role($rolename, [@tests]);

    host 'hostname' => role('test');

file($glob, $target)

    role 'test' => file("lighttpd/app/*.conf", "/etc/lighttpd");

See Csistck::Test::File

template($template, $target, [%args])

    role 'test' => template("sys/motd", "/etc/motd", { hot => 'dog' });

See Csistck::Test::Template

permission($glob, %args)

See Csistck::Test::Script

pkg($package, [$type])

Check for package using system package manager. The package argument may be specified as a string, or as a hashref to specify package names for multiple package managers. The package manager will be automatically detected if no package manager is specified.

    option 'pkg_type' => 'dpkg';
    role 'test' => 
        pkg("lighttpd", 'dpkg'),
        pkg({
            dpkg => 'snmp-server',
            pkg_info => 'net-snmp'
