Docker: Nginx doesn't run if I declare volumes in docker-compose.yml

I'm trying to run nginx as a container in docker using docker-compose but unfortunately, I'm not able to run it properly.

Here is my docker-compose.yml:

version: '3'
services:
 webserver:
  container_name: webserver
  hostname: webserver
  image: nginx
  ports:
   - 80:80
   - 443:443
  volumes:
   - ./nginx:/etc/nginx

and here is the error:

/docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration
/docker-entrypoint.sh: Looking for shell scripts in /docker-entrypoint.d/
/docker-entrypoint.sh: Launching /docker-entrypoint.d/10-listen-on-ipv6-by-default.sh
10-listen-on-ipv6-by-default.sh: info: /etc/nginx/conf.d/default.conf is not a file or does not exist
/docker-entrypoint.sh: Launching /docker-entrypoint.d/20-envsubst-on-templates.sh
/docker-entrypoint.sh: Configuration complete; ready for start up
2021/01/18 19:04:26 [emerg] 1#1: open() "/etc/nginx/nginx.conf" failed (2: No such file or directory)
nginx: [emerg] open() "/etc/nginx/nginx.conf" failed (2: No such file or directory)

I've used both relative and absolute paths in volumes but none of them worked. If I have the directory available on the host, it won't work. If I don't have the directory in the host, when I run docker-compose up, it will create an empty directory for nginx in the host but it will be left empty.

Any ideas what's wrong with my setup?

Thank you.

No don't try to modify all the confs manually in the containers itself.

Nginx have /etc/nginx/conf.d for that so mount your customs confs inside.

Example:

You current directory shouldl look like this:

.
├── conf
│   └── custom.conf
├── docker-compose.yml
└── html
    └── index.html

docker-compose.yml

services:
  nginx:
    image: nginx:latest
    ports:
      - 80:80
    volumes:
      - ./conf:/etc/nginx/conf.d # custom conf goes here
      - ./html:/tmp              # custom html goes here

I just put the html inside "/tmp" for showing you that my custom config works ..

./conf/custom.conf

server {
    listen     80;
    location / {
            root /tmp/;
            index  index.html index.htm;
    }
}

./html/index.html

<h1>nginx custom conf</h1>

Then

$ docker-compose up -d
Creating network "nginx_default" with the default driver
Creating nginx_nginx_1 ... done

$ curl localhost
<h1>nginx custom conf</h1>
