My host machine is on aws lightsail ubuntu 16.

Everything working working in my local machine but on aws ubuntu 16.

I facing the error: `nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied)`

This is my Dockerfile for nginx:

```
FROM nginxinc/nginx-unprivileged:1-alpine

COPY ./default.conf /etc/nginx/conf.d/default.conf
COPY ./uwsgi_params /etc/nginx/uwsgi_params

USER root

RUN mkdir -p /vol/static
RUN chmod 755 /vol/static

USER nginx

```

is there anyone know how to solve the problem?
