How to enable Nginx to read docker.sock?

Question

Nginx

There is a server with docker and nginx. We need the ability to connect via websocket with containers ( doc .). nginx config:

server {
    server_name domain.ru;

    location ~ws/?$ {
        proxy_pass http://unix:/var/run/docker.sock;
        proxy_http_version 1.1;
        proxy_set_header Upgrade "websocket";
        proxy_set_header Connection "upgrade";
    }
}

When trying to connect, the websocket gives a 502 error, and in nginx.error:

connect() to unix:/var/run/docker.sock failed (13: Permission denied

As I understand it, the problem is that nginx runs under www-data, and docker.sock runs under the docker group. You can do sudo usermod -aGdocker www-datait, but I understand that it is not safe.
