Simple web-focused Docker-based mini-PaaS server

How does that compare to dokku?

As far as I know it is completely Dockerfile-based, whereas dokku utilizes Procfiles. Therefore you could build and start any Docker container you like.

Hi.

Let's pretend that I'm an intermediate developer with no knowledge about sysadmin or even deployments. How would you break this down and ELI5 [0].

How does Packer fit into all of this (assuming I'd use Digital Ocean). What's Vagrant for? What does Virtual Machine do here? Do I need these three machines on the target VPS or only on my local development machine? To add my DO keys do I need to ssh into vagrant once it's up and running?

You provide the octovagrant box, is it secure? Is Vagrant production-ready or is it not part of the production mix? You've got 6 cookbooks listed in the cookbook repo. Do I need all of them? How do I use/install each of them?

What does Docker do? Once I've done all of this setup work, how can I push up all of my code to the desired VPS? Do any of the defaults have security provisions and set up ufw rules to only allow port 80 etc [1], disallow root access, only allow ssh access and all of that goodness? If I use this over manually provisioning and securing servers, do I get sane and secure defaults?

That's a lot of questions, but I may not be the only one asking them, so if I may so bravely ask, ELI5?

Yeah - currently deploying it from scratch is a little too hard for most people. I'd like to fix that, but just haven't had the time.

I'd honestly love a system that deploys the image for you to the cloud of your choice - with setup for ssh keys and things to make it simple.

Just not in the cards timewise at the moment.

That's the goal - but I was working on this on weekends mostly by myself and I think they have a team working on it full time.

Deis is a much more mature choice and is based on CoreOS which is awesome.
