Nginx within docker start - docker

Question

I can't start nginx in docker.
My Dockerfile:
FROM ubuntu
RUN apt-get install -y nginx
RUN useradd nginx
ADD nginx.conf /etc/nginx/
COPY conf.d/ /etc/nginx/conf.d
COPY vladislav.crt /etc/nginx/vladislav.crt
COPY vladislav.csr /etc/nginx/vladislav.csr
COPY vladislav.key /etc/nginx/vladislav.key
COPY dhparam.pem /etc/nginx/dhparam.pem
EXPOSE 80 443
CMD ["nginx", "-g", "daemon off;"]
I just build my image using next command
docker build -t custom_nginx .
docker run --name nginx_test custom_nginx
Where is my mistake?
