tao12345666333 opened a new issue #59:
URL: https://github.com/apache/apisix-ingress-controller/issues/59
I occasionally encounter failures when requesting the admin API of the
APISIX cluster.
```
{"error_msg":"timeout"}
```
This will cause the Ingress Controller to fail to create the corresponding
resources normally. like this:
```
$ kubectl -n cloud logs ingress-controller-d978b79d4-s8kgk
