### Current Behavior APISIX is throwing an error related to port being 0 when upstream has discovery_type "dns". same exact setup works fine with clusters from other kubernetes providers. ### Expected Behavior Should not throw the error `http_access_phase(): failed to set upstream: invalid nodes format: failed to validate item 1: property "port" validation failed: expected 0 to be at least 1` ### Error Logs in web response - 503 Service Temporarily Unavailable in apisix pod - init.lua:520: http_access_phase(): failed to set upstream: invalid nodes format: failed to validate item 1: property "port" validation failed: expected 0 to be at least 1 ### Steps to Reproduce 1. Create a standard Google Kubernetes Engine cluster. 2. Install APISIX with ingress controller and dashboard via api7 helm chart version 0.8.4 using this [values.yaml](https://gist.githubusercontent.com/ukanwat/46b505edccf4d10f7241042815f72f72/raw/8f8af4ca5803a4b60e780e281a5c7609731877de/apisix-values.yaml) file (in ingress-apisix namespace). 3. create this upstream via admin api - ` { "id": "398808046194655761", "create_time": 1647237719, "update_time": 1647237719, "timeout": { "connect": 6, "send": 6, "read": 6 }, "type": "roundrobin", "scheme": "http", "discovery_type": "dns", "pass_host": "node", "name": "apisix-dashboard", "service_name": "apisix-dashboard.ingress-apisix.svc.cluster.local", "keepalive_pool": { "idle_timeout": 60, "requests": 1000, "size": 320 } }` 4. create this route via admin api - `{"id":"398808266596942353","create_time":1647237850,"update_time":1647441243,"uri":"/*","name":"apisix-dashboard","priority":50,"methods":["GET","POST","PUT","DELETE","PATCH","HEAD","OPTIONS","CONNECT","TRACE"],"host":"apisix-dashboard.example.com","plugins":{"redirect":{"http_to_https":true}},"upstream_id":"398808046194655761","labels":{"API_VERSION":"v1"},"status":1}` 5. visit the host in the route and then check the logs in the apisix pod. ### Environment - APISIX version (run `apisix version`): 2.12.1 - Operating system (run `uname -a`): kubernetes (GKE) Rest of the values are whatever is bundled in apisix/apisix version 0.8.4 helm chart. - OpenResty / Nginx version (run `openresty -V` or `nginx -V`): - etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`): - APISIX Dashboard version, if relevant: - Plugin runner version, for issues related to plugin runners: - LuaRocks version, for installation issues (run `luarocks --version`): -- This is an automated message from the Apache Git Service.
