The following code uses Stingray's RESTful API to add a pool. The code is written in Perl. This program creates a new pool, "pltest", first doing a GET to make sure the pool doesn't already exist, and if the pool doesn't exist, the pool is created by doing a PUT with just the minimum data needed to create a pool. In this case the program creates a properties hash with just one node. All other values will get default values when Stingray creates the pool.
addpool.pl
#!/usr/bin/perl
use REST::Client;
use MIME::Base64;
use JSON;
# Since Stingray is using a self-signed certificate we don't need to verify it
$ENV{'PERL_LWP_SSL_VERIFY_HOSTNAME'} = 0;
my $poolName = 'pltest';
my %pool = (properties => {basic => {nodes => [ '192.168.168.135:80']}});
my $url = "/api/tm/1.0/config/active/pools/$poolName";
# Set up the connection
my $client = REST::Client->new();
$client->setHost("https://stingray.example.com:9070");
$client->addHeader("Authorization", "Basic " . encode_base64("admin:admin"));
#First see if the pool already exists
$client->GET($url);
if ($client->responseCode == 404) {
$client->addHeader("Content-Type", "application/json");
$client->PUT($url, encode_json(\%pool));
my $poolConfig = decode_json $client->responseContent();
if ($client->responseCode() == 201) { # When creating a new resource we expect to get a 201
print "Pool $poolName added";
} else {
print "Error adding pool. status=" . $client->responseCode() . " Id=" . $vsConfig->{error_id} . ": " . $vsConfig->{error_text} . "\n";
}
} else {
if ($client->responseCode() == 200) {
print "Pool $poolName already exists";
} else {
print "Error getting pool config. status=" . $client->responseCode() . " Id=" . $vsConfig->{error_id} . ": " . $vsConfig->{error_text} . "\n";
}
}
Running the example
This code was tested with Perl 5.14.2 and version 249 of the REST::Client module.
Run the Perl script as follows:
$ addpool.pl
Pool pltest added
Notes
The only difference between doing a PUT to change a resource and a PUT to add a resource is the HTTP status code returned. When changing a resource 200 is the expected status code and when adding a resource, 201 is the expected status code.
