個人用 Mac および Docker digitalocean ドロップレットで openresty docker ( https://github.com/3scale/docker-openresty ) を起動しようとすると、エラーが発生します。

DEBG 'openresty' stderr output:
nginx: [emerg] bind() to 0.0.0.0:8080 failed (98: Address already in use)

構成:

1) Dockerfile

FROM 3scale/openresty
ADD openresty.conf /etc/supervisor/conf.d/
ADD . /var/www
CMD ["supervisord"]

2) Openresty.conf

[program:openresty]
command=/opt/openresty/nginx/sbin/nginx -p /var/www/ -c config/nginx.conf
autorestart=true

3) config/nginx.conf

worker_processes  1;
error_log logs/error.log;
events {
    worker_connections 1024;
}
http {
server {
    listen 8080;
    location / {
        default_type text/html;
        content_by_lua '
            ngx.say("<p>hello, world</p>")
        ';
    }
}
}

起動方法：

docker build -t resty_docker .
docker run resty_docker
