I am deploying php and redis to a local minikube cluster but getting below error related to name resolution.

Warning: Redis::connect(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in /app/redis.php on line 4

Warning: Redis::connect(): connect() failed: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in /app/redis.php on line 4

Fatal error: Uncaught RedisException: Redis server went away in /app/redis.php:5 Stack trace: #0 /app/redis.php(5): Redis->ping() #1 {main} thrown in /app/redis.php on line 5

I am using below configurations files:

apache-php.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: webserver
  labels:
    app: apache
spec:
  replicas: 1
  selector:
    matchLabels:

        volumeMounts:

redis.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis
  labels:
    app: redis
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis
  template:

      labels:

apiVersion: v1

spec:
  type: NodePort
  ports:
    - port: 6379
      targetPort: 6379
  selector:
    app: redis

And I am using the below PHP code to access Redis, I have mounted below code into the apache-php deployment.

<?php
ini_set('display_errors', 1);
$redis = new Redis();
$redis->connect("redis-service", 6379);
echo "Server is running: ".$redis->ping();

Cluster dashboard view for the services is given below:

Thanks in advance.

When I run env command getting below values related to redis and when I use the IP:10.104.115.148 to access redis then it is working fine.

REDIS_SERVICE_PORT=tcp://10.104.115.148:6379
REDIS_SERVICE_PORT_6379_TCP=tcp://10.104.115.148:6379
REDIS_SERVICE_SERVICE_PORT=6379
REDIS_SERVICE_PORT_6379_TCP_ADDR=10.104.115.148
REDIS_SERVICE_PORT_6379_TCP_PROTO=tcp```
