This repo contains a basic build for a LAMP stack project. Just change the variable values in the base.conf file for your needs:

# APPNAME is what you want your container to be called
# EXTERNAL_PORT is the port you want to be accessible on your local loopback interface

APPNAME="php-exp"
EXTERNAL_PORT="8080"

Then run build.sh to both build and run the container. The contents of /app is where your application will be served from. The default index.php just shows your current phpinfo(), so replace as needed.
