NAME

Net::Etcd - etcd v3 REST API.

SYNOPSIS

    Etcd v3.1.0 or greater is required.   To use the v3 API make sure to set environment
    variable ETCDCTL_API=3.  Precompiled binaries can be downloaded at https://github.com/coreos/etcd/releases.

    $etcd = Net::Etcd->new(); # host: 127.0.0.1 port: 2379
    $etcd = Net::Etcd->new({ host => $host, port => $port, ssl => 1 });

    # put key
    $result = $etcd->put({ key =>'foo1', value => 'bar' });

    # get single key
    $key = $etcd->range({ key =>'test0' });

    # return single key value or the first in a list.
    $key->get_value

    # get range of keys
    $range = $etcd->range({ key =>'test0', range_end => 'test100' });

    # return array { key => value } pairs from range request.
    my @users = $range->all

    # watch key range, streaming.
    $watch = $etcd->watch( { key => 'foo', range_end => 'fop'}, sub {
        my ($result) =  @_;
        print STDERR Dumper($result);
    })->create;

    # create/grant 20 second lease
    $etcd->lease( { ID => 7587821338341002662, TTL => 20 } )->grant;

    # attach lease to put
    $etcd->put( { key => 'foo2', value => 'bar2', lease => 7587821338341002662 } );

    # add new user
    $etcd->user( { name => 'samba', password => 'foo' } )->add;

    # add new user role
	$role = $etcd->role( { name => 'myrole' } )->add;

    # grant read permission for the foo key to myrole
    $etcd->role_perm( { name => 'myrole', key => 'foo', permType => 'READWRITE' } )->grant;

    # grant role
    $etcd->user_role( { user => 'samba', role => 'myrole' } )->grant;
