php - 根据标签过滤实例

Question

我收到验证错误消息

$workers = array('Filters' => array(array('Name' => 'Tags', array(array('Key' => 'Name', 'Values' => array('mworker'))))));

$list = $ec2Client->describeInstances($workers);

错误详情：

[Filters][0][Filter] must be an array of properties. Got a numerically indexed array.'

这是 SDK2

Answer 1

找到正确的语法：

$workers = array(array('Filters' => array('Name' => 'Tags', array('Key' => 'Name', 'Values' => array('mworker')))));

Answer 2

这实际上对我不起作用 - 按标签搜索的正确方法似乎是：

$response = $ec2->describeInstances(array(
    'Filters' => array(
        array('Name' => 'instance-type', 'Values' => array('m1.small')),
        array('Name' => 'tag-value', 'Key' => 'Name', 'Values' => array('Testing'))
    )
));

其中还有一个过滤器instance-type来显示它们是如何组合的。
