Why does the deployment "nginx-deploy" exceed its progress deadline error occur?

Question

The docker image stored in the ACR was distributed to the AKS using azure devops pipelines. Then an error occurs.

This is a docker-compose file that creates a docker image for me to use.

# docker-compose.yml

version: "3.9"
services:
  spring-app:
    build:
      context: .
      dockerfile: Dockerfile-app
    image: acrprod0327.azurecr.io/production/spring-app
    container_name: spring-app
    ports:
      - "8080:8080"
  web:
    build:
      context: .
      dockerfile: Dockerfile-nginx
    image: acrprod0327.azurecr.io/production/nginx-alpine
    container_name: nginx-alpine
    ports:
      - "80:80"
    depends_on:
      - spring-app

Below is the ingress & service & deployment file distributed to AKS.

Below are the errors that occur when you run the docker run command on the docker image.

enter image description here

Below is the contents of the nginx.conf file.

# nginx.conf

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    upstream backend {
        server spring-app:8080;
    }

    server {
        listen 80;
        server_name localhost;

        location / {
            resolver 127.0.0.1 [::1]:8080 valid=30s;
            proxy_pass http://backend;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
        }
    }

    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    keepalive_timeout  65;
    include /etc/nginx/conf.d/*.conf;
}

It is speculated that the reason why nginx-deploy exceeded its progress deadline is the problem of setting up the nginx.conf file.

However, I think there will be something I am missing, so I would like to get feedback.

I added the nginx.conf resolver setting to fix the error host not found.
Reviewed 2 docker images I created. 2-1. Problem with nginx image.
Modified the service & deployment file.

The same error occurs
