I'm sorry about your frustration -- I've been there many times, but taking your hellish experience and parlaying that into "web deployments suck these days because my development environment didn't meet the system requirements and therefore their methods suck" is a bit nonsensical.
I would direct you to the system requirements for the installation in question:
Hardware Requirements
Dual core CPU recommended 1 GB RAM minimum (with swap) 64 bit Linux compatible with Docker Software Requirements
Postgres 9.3+ Redis 2.6+ Ruby 2.0+ (we recommend 2.0.0-p353 or higher)
I would say that 32bit != 64 bit. Blaming the system seems like blaming a toaster that won't make tea. We could certainly hack the toaster into making tea, but your inability to quickly make tea with a toaster is not the fault of the toaster, toast or people that make toasters. Dismissing toast as a silly breakfast food and lamenting why more tea isn't made is pretty much the point of your rant.
You are certainly welcome to install the forum or do whatever it is you want, it is Open Source. However, it's rather uncouth to blame a process for which the problem was your situation. Rather than ranting about how badly Docker sucks, perhaps you could contribute back to the forum software in question and create your own Awesome Deployment System. Nothing is stopping you.
