我想使用go-client API从k8s集群中获取Secret对象
我有类似的功能
def myajaxtestview(request):
look_for = request.POST['object_type']
#lets say you have model Items
my_items= serializers.serialize('json', Items.objects.filter(object_type=look_for))
return JsonResponse(my_items)
GetClientOutOfCluster基本上是从集群或本地〜/ .kube / config中检索配置
我使用metav1.LabelSelector就像我生成新的Deployment对象时一样。所以我觉得我很酷。但是ListOptions.LabelSelector是一个字符串。 当我运行函数时,它将失败。
func GetSecret( version string) (retVal interface{}, err error){
clientset := GetClientOutOfCluster()
labelSelector := metav1.LabelSelector{MatchLabels: map[string]string{"version":version}}
listOptions := metav1.ListOptions{
LabelSelector: labelSelector.String(),
Limit: 100,
}
secretList, err := clientset.CoreV1().Secrets("namespace").List( listOptions )
retVal = secretList.Items[0]
return retVal, err
}
我在任何地方都找不到使用此功能的示例。文档假定您知道什么是LabelSelector。
ListOptions的LabelSelector的格式是什么?
谢谢
答案 0 :(得分:3)
func GetSecret( version string, param2 string) (retVal interface{}, err error){
clientset := GetClientOutOfCluster()
labelSelector := fmt.Sprintf("version=%s, param2=%s", version, param2)
listOptions := metav1.ListOptions{
LabelSelector: labelSelector,
Limit: 100,
}
secretList, err := clientset.CoreV1().Secrets("namespace").List( listOptions )
retVal = secretList.Items[0]
return retVal, err
}

您可以使用提供的k8s函数执行toString操作
import "k8s.io/apimachinery/pkg/labels"
...
func GetSecret(version string) (retVal interface{}, err error){
clientset := GetClientOutOfCluster()
labelSelector := metav1.LabelSelector{MatchLabels: map[string]string{"version":version}}
listOptions := metav1.ListOptions{
LabelSelector: labels.Set(labelSelector.MatchLabels).String(),
Limit: 100,
}
secretList, err := clientset.CoreV1().Secrets("namespace").List(listOptions)
retVal = secretList.Items[0]
return retVal, err
}
