Bring phabricator to Raspberry Pi 3 B+ — armv7 in general

[maxiride]

Hi @davidbarratt , I wanted to bring an installation of Phabricator on my Pi 3 B+ (hardware architecture ARM64v8 which however runs Raspbian which is 32-bit, hence the actual kernel provided is ARMv7).

If I understood correctly from my brainstorming this stack isn't compatible with ARMv7 just because of the MariaDB images which (on docker hub) aren't available for ARMv7 but only for ARMv8 (64-bit).

I dived in the Docker world just recently and among all the thousands of apps for ARM devices out there, Phabircator wasn't among them so if you could please confirm this hypothesis of mine I'd just fork the repo and attempt to set it up using Postgres which provides ARMv7 compatible images and maybe do a PR for a new ARMv7 branch.

I fought a bit to complete the deploy of Phabricator on the Pi 3 B+ but eventually, I made it successfully.
I actually modified the docker-compose.yml on my host but since it is a very small modification I thought that it would be better to make a PR with the steps to achieve it in the readme rather than branching out and having a different branch for arm devices.

Let me know your thoughts! I recognize that this might fit a small niche but... whatever xD I wanted Phabricator on my Pi and thought to share\improve upon the repo for anyone that might pass by.

In Docker container it is not localhost, but 127.0.0.1 @maxiride
