How to properly connect virtual hosts in docker/apache2?

Question

Apache HTTP Server

I am mastering docker, I want to launch nginx in parallel for a separate application, and apache for a bitrix box on a local machine.
Nginks configured, hosts are connected, everything works.
And here with the Apache there were problems.
I do not understand the principle of connecting Apache hosts. If everything is ok with nginx, I changed something in the host, rebooted the container and you are glad that everything is working, then Apache has some kind of crap already at the stage of connecting hosts.
I tried to connect through the assembly of the dockerfile, but I get the following error (there is no such directory, but how can I access the hosts folder then?):

Building apache
Step 1/6 : FROM httpd:latest
 ---> 19459a872194
Step 2/6 : COPY ./hosts/apache2/sites-available/ /etc/apache2/sites-available
ERROR: Service 'apache' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder011831039/hosts/apache2/sites-available: no such file or directory

Apache dockerfile itself:

FROM httpd:latest
COPY ./hosts/apache2/sites-available/ /etc/apache2/sites-available
RUN a2dissite /etc/apache2/sites-available/000-default.conf
RUN a2dissite /etc/apache2/sites-available/default-ssl.conf
RUN a2ensite /etc/apache2/sites-available/bitrix.conf
RUN service apache2 restart #я не знаю, нужно ли перезапускать в контейнере сервис...

I also tried like this:

FROM httpd:latest

# COPY ./hosts/apache2/sites-available/ /etc/apache2/sites-available

RUN a2dissite ./hosts/apache2/sites-available/000-default.conf
RUN a2dissite ./hosts/apache2/sites-available/default-ssl.conf
RUN a2ensite ./hosts/apache2/sites-available/bitrix.conf

# RUN a2dissite /etc/apache2/sites-available/000-default.conf
# RUN a2dissite /etc/apache2/sites-available/default-ssl.conf
# RUN a2ensite /etc/apache2/sites-available/bitrix.conf

RUN service apache2 restart

Error (no command? how is that?):

What am I doing wrong?

Look, here is a link to the Dockerfile of the official
Apache httpd container installed in /usr/local/apache2 , and the directory structure is something like this.

➜  ~ docker exec -it d1d45faeeb6e /bin/bash
[email protected]:/usr/local/apache2# pwd
/usr/local/apache2

What the hell is pulling docker for the LAMP stack?
Judging by the config, this is the Bitrix environment. Runs and works great on LXD. A container with Nginx Proxy is placed in front.
You will hide on NAT, you will almost certainly have problems with the environment.
