HttpRoute creates upstream with server unix:/var/run/nginx/nginx-503-server.sock and throws 503 error #3139
Description
HttpRoute creates upstream with server unix:/var/run/nginx/nginx-503-server.sock and throws 503 error
To Reproduce
1.install nginx-gateway:
kubectl apply -f https://raw.githubusercontent.com/nginx/nginx-gateway-fabric/v1.5.1/deploy/crds.yaml
kubectl apply -f https://raw.githubusercontent.com/nginx/nginx-gateway-fabric/v1.5.1/deploy/nodeport/deploy.yaml
- Create NodePort Service
apiVersion: v1
kind: Service
metadata:
name: ufo-service
namespace: ufo-ns
spec:
type: NodePort
selector:
app: ufo-app
ports:
- protocol: TCP
name: http
port: 80
targetPort: 8000 # inside container
nodePort: 30007- And HttpRoute
apiVersion: gateway.networking.k8s.io/v1
kind: HTTPRoute
metadata:
namespace: ufo-ns
name: ufo-httproute
spec:
parentRefs:
- name: ufo-gateway
rules:
- matches:
- path:
type: PathPrefix
value: /lol
backendRefs:
- name: ufo-service
port: 80-
check that service itself can be successfuly accessed on that node port:
curl http://vybory.live:30007returns http 200. -
Attempt to access the service via nginx-gateway, notice it throws http 503:
$ curl http://vybory.live/lol
<html>
<head><title>503 Service Temporarily Unavailable</title></head>
<body>
<center><h1>503 Service Temporarily Unavailable</h1></center>
<hr><center>nginx</center>
</body>
</html>
- log into nginx caontainer with
kubectl exec -it --namespace nginx-gateway deployments/nginx-gateway -c nginx -- /bin/sh
- retrieve generated configuration with
nginx -Tand notice thatupstreamdefinition for myufo-servicepoints toserver unix:/var/run/nginx/nginx-503-server.sock;instead of actual service ip:
upstream ufo-ns_ufo-service_80 {
random two least_conn;
zone ufo-ns_ufo-service_80 512k;
server unix:/var/run/nginx/nginx-503-server.sock;
}
upstream ufo-ns_grafana_3000 {
random two least_conn;
zone ufo-ns_grafana_3000 512k;
server 10.20.15.122:3000;
}
- Also notice that at the same time, grafana
upstreamcorrectly references its service ip, and can be accesed via http://grafana.vybory.live

Expected behavior
Expected: the upstream definition int the config should reference service by ip, instead of pointing to unix:/var/run/nginx/nginx-503-server.sock
