Customize Docker Containers

Of course you would love day-to-day updates and still have room to add your own changes. Just add a docker-custom.yml, add version: '2' to the top and override whatever you want.

docker-custom.yml and the ./custom directory are excluded from git.

For example: to add a custom components to the default PHP, add the following docker-custom.yml file:

version: '2'

        build: custom/php7

This won't build the regular php7 directory, instead it will run build in the custom directory. So, next up you copy the php/Dockerfile and add your own additions which will be build everytime updates are available.
