docker-compose container isn't hosting files properly when building server first - docker

Question

I have to host 2 different web apps from a docker container. My first attempt at this worked, but I didn't like it. I have a lamp-base folder that has the Dockerfile that gets the server working, then a docker-compose.yml file that puts everything together. In my first version for the web apps I did build: ./lamp-base/ to make them build the web server, but I feel like that's the wrong approach as it leaves me with 3 images (one for each web app and one for the mysql server). I feel like this should be 2 images and 3 containers. 1 image for the mysql container and 1 image for the web server, then the web apps should be able to use the web server. I was able to build it and make it work, kind of.
The problem is, when I go to the URL I defined and added to my local /etc/hosts file I get the default welcome to apache page, I don't get my web apps. I honestly can't figure out why it isn't working correctly. The healthchecks pass, so the files are being hosted properly, but I can't access the web pages. This might be a little long, but I'll post up the Dockerfile and the docker-compose.yml file as well as the default.conf that get's added to the web server. I have asked all the people I know and no one can figure out why I can't reach the webpages, especially since the healthchecks pass. Thank you for bearing with me on this, here are the files...
Dockerfile...
FROM centos:7

ADD httpd.conf /etc/httpd/conf/httpd.conf
ADD conf.d/default.conf /etc/httpd/conf.d/default.conf
CMD /sbin/httpd -D FOREGROUND
The default.conf file that has the vhosts for the web apps...

I renamed the servers because I don't think I can post the actual server names, sorry.

It all builds correctly, I end up with 2 Images (mysql and server) and 3 containers (mysql, server-one, and server-two) all the healthchecks pass properly, but if I go to http://my.server1.com in my browser I only get the default apache welcome page, I don't get my actual server.
I have also tried removing the server from the docker-compose file and just doing docker build --no-cache . -t lamp-web:dev in the /lamp-base directory, then running the docker-compose up -d and again, it all builds properly I get the right containers, the healthchecks pass, but going to the URL in any browser just yields the default welcome to apache page. I can't figure out why the web containers aren't working correctly.
On a side note, if I remove the web server entirely and change the image: lamp-web:dev to build: ./lamp-base/ on both web containers it works correctly, but I end up with a bunch of images. Am I just going about this the wrong way? Should both the web containers have to build their own web server image? Any help is greatly appreciated. Thank you and sorry for the long post.
