NAME

Search::Elasticsearch::TestServer - A helper class to launch Elasticsearch nodes

VERSION

version 6.00

SYNOPSIS

    use Search::Elasticsearch;
    use Search::Elasticsearch::TestServer;

    my $server = Search::Elasticsearch::TestServer->new(
        es_home    => '/path/to/elasticsearch',  # defaults to $ENV{ES_HOME}
        es_version => '6_0'                      # defaults to $ENV{ES_VERSION}
    );

    my $nodes = $server->start;
    my $es    = Search::Elasticsearch->new( nodes => $nodes );
    # run tests
    $server->shutdown;

DESCRIPTION

The Search::Elasticsearch::TestServer class can be used to launch one or more instances of Elasticsearch for testing purposes. The nodes will be shutdown automatically.

METHODS

"new()"

    my $server = Search::Elasticsearch::TestServer->new(
        es_home    => '/path/to/elasticsearch',
        es_version => '6_0',
        instances => 1,
        http_port => 9600,
        es_port   => 9700,
        conf      => ['attr.foo=bar'],
    );

Params:

"es_home"
Required. Must point to the Elasticsearch home directory, which contains "./bin/elasticsearch". Defaults to $ENV{ES_HOME}
"es_version"
Required. Accepts a version of the client, eg `6_0`, `5_0`, `2_0`, `1_0`, `0_90`. Defaults to $ENV{ES_VERSION}.
"instances"
The number of nodes to start. Defaults to 1
"http_port"
The port to use for HTTP. If multiple instances are started, the "http_port" will be incremented for each subsequent instance. Defaults to 9600.
"es_port"
The port to use for Elasticsearch's internal transport. If multiple instances are started, the "es_port" will be incremented for each subsequent instance. Defaults to 9700
"conf"
An array containing any extra startup options that should be passed to Elasticsearch.

"start()"

    $nodes = $server->start;

Starts the required instances and returns an array ref containing the IP and port of each node, suitable for passing to "new()" in Search::Elasticsearch:

    $es = Search::Elasticsearch->new( nodes => $nodes );

"shutdown()"

    $server->shutdown;

Kills the running instances. This will be called automatically when $server goes out of scope or if the program receives a "SIGINT".
