use of bitnami codeigniter Docker container

First let me say that I have an application up and running on AWS Lightsail that uses CI 3 and Grocery Crud and works fine. I want to ad some features that I think will help in marketing my product (which, btw, is free). When I originally wrote the CI application on my Windows PC and uploaded it to AWS, I found some parts didn't work. Through a huge amount of effort I was able to debug my server app remotely. 

I have sworn that if I make any changes to the server code I need a better way to debug this than to remote debug on AWS. Thus I have decided to use  Docker so I can debug directly on my Ubuntu laptop. I have pretty much standardized on Bitnami to handle the server config. 

Bitnami has docker development containers for CI3, mariaDB, php, and Apache. On my laptop my CI application is at /var/html/www/sub_crud. Below this is the /Application, /APPATHcache, /External Libraries directories. These are the normal CI things (and php runtime) that my app uses. My plan is to create a copy of this sub_crud directory in a new layer in the apache image. I will do this by running docker build image from the /var directory. 

Bitnami containers use the 4 images I talked about. In my case I will use my modified image that I call apache-with-code to start the Apache server.  Since I already have the CI source and the php runtime in sub_crud that I am copying to the apache-with_code image, I am thinking that I just need to start up the following containers:

apache-with-code
mariaDB

Will this possibly work?

You will have to try it to see if it will work.

What did you Try? What did you Get? What did you Expect?

Thanks insitefx. I am just checking to see if I have entered a known dead end. Turns out that when building a layer onto an existing image, you can only copy files and dirs that are in sub dirs of the location of the Dockerfile. I finally got the updated image built last night. I had to use .dockerignore to keep the cache files out of the image. I guess I could switch the session caches to use the database instead but I don't think it needs to persist across reboots.

So I got the image built. I run the new container with:
richb201@richb201-XPS-13-9370:/var/www/html$ docker container run -p 80:80 --rm apache-with-code

Now I go over to my browser and type localhost. Here is what I get:

The connection was reset.

I also tried http://localhost/sub_crud:80 with the same results. Anyone know what youwould try next?
