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
$put_key = $etcd->put({ key =>'foo1', value => 'bar' });
# check for success of a transaction
$put_key->is_success;
# 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
# delete single key
$etcd->deleterange({ key => 'test0' });
# 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;

# defrag member's backend database
