标尺中的动态普罗米修斯标签

Question

我想知道是否/如何添加动态标签。我不知道要添加到量规值中的键或标签的数量。

我尝试过的事情

labelsContainers = []string{"node", "container", "pod", "qos", "namespace", "nodepool"}

// Requested resources
requestedContainerCPUCoresGauge = prometheus.NewGaugeVec(
    prometheus.GaugeOpts{
        Namespace: namespace,
        Subsystem: "pod_container_resource_requests",
        Name:      "cpu_cores",
        Help:      "Requested CPU cores in Kubernetes configuration",
    },
    labelsContainers)

for _, containerMetric := range containerMetrics {
    containerLabels := prometheus.Labels{
        "node":      containerMetric.Node,
        "container": containerMetric.Container,
        "qos":       containerMetric.Qos,
        "pod":       containerMetric.Pod,
        "namespace": containerMetric.Namespace,
    }

    for key, value := range containerMetric.NodeLabels {
        containerLabels[key] = value
    }

    requestedContainerCPUCoresGauge.With(containerLabels).Set(containerMetric.RequestedCPUCores)
    requestedContainerRAMBytesGauge.With(containerLabels).Set(containerMetric.RequestedMemoryBytes)
}

问题

这引发了恐慌。我认为这是因为舞会客户完全希望labelsContainers中定义的那些标签，并且不允许进一步的标签。如何创建可以添加其他（未知）标签的量规？
