Solution to the problem that docker nginx cannot be accessed after running

## 1

I'm learning docker deployment recently, and I initially planned to dockerize nginx.

Refer to the official Docker image description for custom configuration

After copying the official nginx.conf, I modified and added some customizations, mainly blocking the default.conf and the include folder sites-available

# include /etc/nginx/conf.d/.conf;
include /etc/nginx/sites-available/;

Official original configuration

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;

  #gzip on;

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

Create a new docker-compose.yml file and simply specify images, names, ports, and mount local files instead of defaults.

version: '3'
services:
 nginx-proxy:
  image: nginx
  container_name: nginx
  ports:
   -8081:80
  volumes:
   - ./nginx/nginx.conf:/etc/nginx/nginx.conf:ro

After running docker-compose up, it keeps getting stuck at attaching to nginx, and the browser cannot access the port address

Starting nginx ... done
Attaching to nginx

I don't know where the problem is. After searching for information, I found that I can use the tty parameter for debugging.

Modify docker-compose.yml and add a configuration tty:true.

docker exec -it nginx /bin/bash

I found that after I deleted the default default.conf and did not add any other configuration files, the previous sites-available folder was empty.

I dug myself up, add

-./nginx/sites-available:/etc/nginx/sites-available:ro

And add a configuration file in sites-available.

/etc/nginx/sites-available# ls
default.conf

After running, access to the port address is finally normal
