describe_domain ( $opt )

Returns information about the specified domain including description and status.

Access Control

You can use IAM policies to control this action’s access to Amazon SWF resources as follows:

  • Use a Resource element with the domain name to limit the action to only specified domains.
  • Use an Action element to allow or deny permission to call this action.
  • You cannot use an IAM policy to constrain this action’s parameters.

If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing OperationNotPermitted. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows.

Examples

Workflow Domain CRUD.

Shows an example of workflow domain CRUD methods.

This sample uses anonymous functions, which are only available in PHP 5.3+. For PHP 5.2 users, you must used named functions instead of anonymous ones.

// Instantiate the class
$swf = new AmazonSWF();

// Setup
$timestamp = time();
$workflow_domain = 'my-domain' . $timestamp;

//-----------------------------------------------------------------//
// Register a new workflow domain

echo "# Registering a new workflow domain, \"${workflow_domain}\"..." . PHP_EOL;

$domain = $swf->register_domain(array(
	'name' => $workflow_domain,
	'workflowExecutionRetentionPeriodInDays' => '1'
));

if ($domain->isOK())
{
	echo 'Domain was created successfully.' . PHP_EOL;
}
else
{
	echo 'Domain creation failed.';
}

echo PHP_EOL;

//-----------------------------------------------------------------//
// List all registered workflow domains

echo '# Listing all registered workflow domains...' . PHP_EOL;

// Grab a list of "registered" domains and list them.
// Anonymous callbacks require PHP 5.3. PHP 5.2 users can create a
// named function and pass it to the each() method.
$swf->list_domains(array(
	'registrationStatus' => AmazonSWF::STATUS_REGISTERED
))
->body->domainInfos()->each(function($item)
{
	echo (string) $item->status . ': ' . (string) $item->name . PHP_EOL;
});

echo '.' . PHP_EOL . PHP_EOL;

//-----------------------------------------------------------------//
// Describing a specific domain

echo "# Describing the \"${workflow_domain}\" domain..." . PHP_EOL;

// Describe a domain
$describe = $swf->describe_domain(array(
	'name' => $workflow_domain
));

print_r($describe->body);

echo PHP_EOL;

//-----------------------------------------------------------------//
// Deprecate a workflow domain

echo "# Deprecating the \"${workflow_domain}\" domain..." . PHP_EOL;

$deprecate = $swf->deprecate_domain(array(
	'name' => $workflow_domain
));

do {
	sleep(1);

	$describe = $swf->describe_domain(array(
		'name' => $workflow_domain
	));
}
while ($deprecate->status === 200 && (string) $describe->body->domainInfo->status !== AmazonSWF::STATUS_DEPRECATED);

if ($deprecate->isOK())
{
	echo "Domain \"${workflow_domain}\" has been successfully deprecated." . PHP_EOL;
}
else
{
	echo "Domain has failed to deprecated." . PHP_EOL;
	print_r($deprecate->body);
}
