Issue description

apisix集群物理机部署非容器环境，这套集群是否可以同时作为apisix-ingress-controller 的apisix/admin 使用，又提供给外部物理机环境通过Dashboard配置路由，上游。既我想容器和物理机混用apisix集群。 实测下来好像不可以，不知道是否支持？有没有计划支持？ apisix-ingress-controller 报错信息 2021-10-13T16:15:38+08:00 error apisix/upstream.go:121 failed to convert upstream item {“url”: “http://192.168.8.9:9080/apisix/admin/upstreams”, “upstream_key”: “/apisix/upstreams/376788208932881080”, “error”: “unexpected non-empty object”} 2021/10/13 下午4:15:38 2021-10-13T16:15:38+08:00 error apisix/cluster.go:199 failed to list upstreams in APISIX: unexpected non-empty object 2021/10/13 下午4:15:40 2021-10-13T16:15:40+08:00 error apisix/upstream.go:121 failed to convert upstream item {“url”: “http://192.168.8.9:9080/apisix/admin/upstreams”, “upstream_key”: “/apisix/upstreams/376788208932881080”, “error”: “unexpected non-empty object”} 2021/10/13 下午4:15:40 2021-10-13T16:15:40+08:00 error apisix/cluster.go:199 failed to list upstreams in APISIX: unexpected non-empty object 2021/10/13 下午4:15:42 [GIN] 2021/10/13 - 16:15:42 | 200 | 34.554µs | ip | GET “/healthz” 2021/10/13 下午4:15:42 2021-10-13T16:15:42+08:00 error apisix/upstream.go:121 failed to convert upstream item {“url”: “http://192.168.8.9:9080/apisix/admin/upstreams”, “upstream_key”: “/apisix/upstreams/376788208932881080”, “error”: “unexpected non-empty object”} 2021/10/13 下午4:15:42 2021-10-13T16:15:42+08:00 error apisix/cluster.go:199 failed to list upstreams in APISIX: unexpected non-empty object 2021/10/13 下午4:15:44 2021-10-13T16:15:44+08:00 error apisix/upstream.go:121 failed to convert upstream item {“url”: “http://192.168.8.9:9080/apisix/admin/upstreams”, “upstream_key”: “/apisix/upstreams/376788208932881080”, “error”: “unexpected non-empty object”} 2021/10/13 下午4:15:44 2021-10-13T16:15:44+08:00 error apisix/cluster.go:199 failed to list upstreams in APISIX: unexpected non-empty object 2021/10/13 下午4:15:44 [GIN] 2021/10/13 - 16:15:44 | 200 | 37.139µs | ip | GET “/healthz” 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 error apisix/upstream.go:121 failed to convert upstream item {“url”: “http://192.168.8.9:9080/apisix/admin/upstreams”, “upstream_key”: “/apisix/upstreams/376788208932881080”, “error”: “unexpected non-empty object”} 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 error apisix/cluster.go:199 failed to list upstreams in APISIX: unexpected non-empty object 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 error apisix/cluster.go:161 failed to sync cache {“cost_time”: “8.039422647s”, “cluster”: “default”} 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 error ingress/controller.go:391 failed to wait the default cluster to be ready: unexpected non-empty object 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 info ingress/controller.go:332 controller now is running as a candidate {“namespace”: “ingress-apisix”, “pod”: “apisix-ingress-controller-64f9645f9c-dfp9p”} 2021/10/13 下午4:15:46 I1013 16:15:46.528768 1 leaderelection.go:243] attempting to acquire leader lease ingress-apisix/ingress-apisix-leader… 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 info apisix/cluster.go:152 syncing cache {“cluster”: “default”} 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 info apisix/cluster.go:340 syncing schema {“cluster”: “default”} 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 error apisix/plugin.go:46 failed to list plugins’ names: Get http://192.168.8.9:9080/apisix/admin/plugins/list: context canceled 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 error apisix/cluster.go:360 failed to list plugin names in APISIX: Get http://192.168.8.9:9080/apisix/admin/plugins/list: context canceled 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 warn apisix/cluster.go:324 failed to sync schema: Get http://192.168.8.9:9080/apisix/admin/plugins/list: context canceled 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 error apisix/route.go:117 failed to list routes: Get http://192.168.8.9:9080/apisix/admin/routes: context canceled 2021/10/13 下午4:15:46 2021-10-13T16:15:46+08:00 error apisix/cluster.go:194 failed to list route in APISIX: Get http://192.168.8.9:9080/apisix/admin/routes: context canceled

其中/apisix/upstreams/376788208932881080 是我在dashboard上手动创建的上游 ，dashboard 删除后，ingress可以正常自动注册
