[GitHub] [apisix-ingress-controller] han6565 opened a new issue #778: request help: 新增namespace 然后删除，会一直报not found
han6565 opened a new issue #778:
URL: https://github.com/apache/apisix-ingress-controller/issues/778
### Issue description
在k8集群内，启动apisix-ingress，新增namespace，然后删除会一直报
```
sync namespace info failed, will retry {"namespace": "xxx", "error": "namespaces \"xxx\" not found"}
```
研究了一下，应该是删除namespace触发了delete事件后又触发了update事件，由于无法找到对应的namespace所以会一直报错。不知道大家是否也是这样。
另外还有一个问题
```
// if labels of namespace contains the watchingLabels, the namespace should be set to controller.watchingNamespace
if c.controller.watchingLabels.IsSubsetOf(namespace.Labels) {
c.controller.watchingNamespace.Store(namespace.Name, struct{}{})
}
```
c.controller.watchingLabels.IsSubsetOf(namespace.Labels) 这句如果我是新增的namespace是不会在watchingLabels里面有值的，也就无法将新的namespace加入到watchingNamespace,不知道是不是我哪里配置有问题。我这边watchingLabels似乎始终是空的
mapConfig
```
data:
config.yaml: |
# log options
log_level: "debug"
log_output: "stderr"
http_listen: ":8080"
enable_profiling: true
kubernetes:
kubeconfig: ""
resync_interval: "6h"
app_namespaces:
- "*"
ingress_class: "apisix"
ingress_version: "networking/v1"
apisix_route_version: "apisix.apache.org/v2beta1"
apisix:
default_cluster_base_url: "http://172.24.150.14:9180/apisix/admin"
default_cluster_admin_key: "edd1c9f034335f136f87ad84b625c8f1"
default_cluster_name: ""
```
目前我的解决方法比较暴力，但是新建namespace和删除都可以正常watching
```
if ev.Type != types.EventDelete {
// check the labels of specify namespace
namespace, err := c.controller.kubeClient.Client.CoreV1().Namespaces().Get(ctx, ev.Object.(string), metav1.GetOptions{})
if err != nil {
if strings.Index(err.Error(), "not found") > 0 && ev.Type == types.EventUpdate {
return nil
}
return err
} else {
// if labels of namespace contains the watchingLabels, the namespace should be set to controller.watchingNamespace
//if c.controller.watchingLabels.IsSubsetOf(namespace.Labels) {
c.controller.watchingNamespace.Store(namespace.Name, struct{}{})
//}
}
} else { // type == types.EventDelete
namespace := ev.Tombstone.(*corev1.Namespace)
if _, ok := c.controller.watchingNamespace.Load(namespace.Name); ok {
c.controller.watchingNamespace.Delete(namespace.Name)
}
// do nothing, if the namespace did not in controller.watchingNamespace
}
```
