3. ConfigMap (false로 되어있으면 true로 변경)

kubectl edit configmap/ingress-nginx-controller -n ingress-nginx
```
data:
  allow-snippet-annotations: "true"
```

 

4. ingress 접속 정보 설정

kubectl edit service/ingress-nginx-controller -n ingress-nginx
```
spec:
  allocateLoadBalancerNodePorts: true
  clusterIP: 10.96.220.148
  clusterIPs:
  - 10.96.220.148
  externalTrafficPolicy: Cluster
  internalTrafficPolicy: Cluster
```

externalTrafficPolicy: Local -> Cluster
Local : 수정하면 파드가 실행중인 노드에서만 접속됌
Cluster : 모든 마스터 및 워커노드 IP에서 접속 가능
