 No, currently we are implementing one-way synchronization, that is, CRDs file -> Apache AIPSIX. If the configuration is modified separately through admin api, it will not be synchronized to CRDs in Kubernetes.
 
 This is because CRDs are generally declared in the file system, and Apply to enter Kubernetes etcd, we follow the definition of CRDs and synchronize to Apache Apisix Data Plane, but the reverse will make the situation more complicated.

+
+So far apisix-ingress-controller doesn't support set admin_key for Apache APISIX, so when you deploy your APISIX cluster, admin_key should be removed from config.
+
+Note since APISIX have two configuration files, the first is config.yaml, which contains the user specified configs, the other is config-default.yaml, which has all default items, config items in these two files will be merged. So admin_key in both files should be removed. You can customize these two configuration files and mount them to APISIX deloyment.
