I am deploying Containerized Laravel to Digital Ocean using the bitbucket pipeline. I am pushing the PHP image to the docker hub and pulling it from there. Everything goes right but in the end, nginx starts to fail. However, I have tried to fix it but still have no luck. However, it works fine locally. I am sharing the code that I have used for server deployment. Any help will be appreciated.

Nginx Code

user  nginx;
worker_processes  1;

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

events {
    worker_connections  1024;
}

http {
    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;
    #tcp_nopush     on;

    keepalive_timeout  65;

    server_tokens off;
    chunked_transfer_encoding off;

    gzip on;
    gzip_types application/json;
    gzip_min_length 1000;

    include /etc/nginx/conf.d/*.conf;
}

Default.conf code

server {
  listen 80;
  index index.php index.html;
  root /var/www/public;

  client_max_body_size 100M; # 413 Request Entity Too Large

  location / {
    root /var/www/public;
    index  index.html index.php;
    try_files $uri $uri/ /index.php?$query_string;
  }

  location ~ .php$ {
    try_files $uri =404;
    fastcgi_split_path_info ^(.+.php)(/.+)$;
    fastcgi_pass php:9000;
    fastcgi_read_timeout 3600;
    fastcgi_index index.php;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param PATH_INFO $fastcgi_path_info;
    send_timeout 3600;
    proxy_connect_timeout 3600;
    proxy_read_timeout    3600;
    proxy_send_timeout    3600;
  }
}
