Docker container not showing site based on newly copied site configuration - docker

Question

This is my Dockerfile.
FROM ubuntu:devel
MAINTAINER ciasto
RUN apt-get update && apt-get install -y apache2 && apt-get clean && rm -rf /var/lib/apt/lists/\*
RUN mkdir /var/run/apache2
COPY mysite.conf /etc/apache2/sites-available/000-default.conf
ENV APACHE\_RUN\_USER www-data
ENV APACHE\_RUN\_GROUP www-data
ENV APACHE\_LOG\_DIR /var/log/apache2
ENV APACHE\_RUN\_DIR /var/run/apache2
EXPOSE 80
CMD \["/usr/sbin/apache2", "-D", "FOREGROUND"\]
I am trying to load my site instead of default 000-default.conf but even though the mysite.conf overwrites 000-default.conf I still keep getting the default homepage of Apache instead.
It doesn't have any affect of a2dissite and then running a2ensite:
# docker build -t myapache .

then I still get default page of Apache and checked by entering running container:

This should fix your problem here. To be add after the COPY:
RUN a2dissite 000-default
RUN a2ensite 000-default
