pioneer-hash opened a new issue #276:
URL: https://github.com/apache/apisix-ingress-controller/issues/276
### Issue description
When there is a problem with upstream resource configuration, delete the
service corresponding to upstream POD and re-expose it.A look at the
Apisix-Ingress log shows that it also monitors old services。
This is deploymen yaml of pod :
`kind: Deployment
metadata:
creationTimestamp: null
labels:
app: web
name: web
spec:
replicas: 1
selector:
matchLabels:
app: web
strategy: {}
template:
metadata:
creationTimestamp: null
labels:
app: web
spec:
containers:
- image: nginx
name: nginx
resources: {}
status: {}
~
`
This is service yaml of pod :
`apiVersion: v1
kind: Service
metadata:
creationTimestamp: "2021-03-02T02:48:52Z"
labels:
app: web
name: web
namespace: default --- there is problematic because my apisix-ingress is
gray-publish of namespace , this servicde can't be found
resourceVersion: "13882151"
selfLink: /api/v1/namespaces/default/services/web
uid: 0d434999-12bb-4dfa-9c93-e69d66290944
spec:
clusterIP: 10.102.85.217
externalTrafficPolicy: Cluster
ports:
- nodePort: 32712
port: 80
protocol: TCP
targetPort: 80
selector:
app: web
sessionAffinity: None
type: NodePort
status:
loadBalancer: {}
`
This is my apisix-upstream.yaml:
`apiVersion: apisix.apache.org/v1
kind: ApisixUpstream
metadata:
name: web
spec:
ports:
- port: 80
loadbalancer:
type: chash
hashOn: cookie
key: sid1
`
when I use kubectl apply -f apisix-upstream.yaml to create upstream
CRD , Appear error ：
E0302 10:59:37.243624 1 apisix_upstream.go:113] error syncing
'default/web': list upstreams failed, err: Get
http://apisix-admin:9180/apisix/admin/upstreams: dial tcp: lookup apisix-admin
on 10.96.0.10:53: server misbehaving。
So I use commamd kubectl delete -f apisix-upstream.yaml and modifi
apisix-upstream.yaml then change the namespace to gray-publish. But the
error log is the same as last time ：
E0302 11:11:37.340643 1 apisix_upstream.go:113] error syncing
'default/web': list upstreams failed, err: Get
http://apisix-admin:9180/apisix/admin/upstreams: dial tcp: lookup apisix-admin
on 10.96.0.10:53: server misbehaving。
### Environment
* your apisix-ingress-controller version (output of
`apisix-ingress-controller version --long`);
* your Kubernetes cluster version (output of `kubectl version`);
* if you run apisix-ingress-controller in Bare-metal environment, also show
your OS version (`uname -a`).
