Micro PAAS

Micro Declarative PAAS System

Want to duplicate a machine? Easy! Everything is in configuration files!

Minimum system intrusion for a PAAS system. Nix installs everything automatically.

Write your own plug-in.

Micro PAAS can be run without root if using ports above 1024.

Do not like it? Copy your Dockerfile-s, docker-compose-${name}.yml files and you can switch, fast.

Requirements

Linux machine
Nix
Docker

Technologies

Docker
Docker Compose
Nix
Supervisord

Usage

Get the code

git clone git://github.com/matejc/upaas.git
cd upaas

Install to /var/upass folder, everything required will be there so make the folder and set write permissions for used user

./install.sh

Now you are going to need config.nix and stack.nix (take a look in the repository for examples). Inside stack.nix, compose object is actually comparable to docker-compose - the same options, or if you prefer you can use composeFile instead to specify absolute path to the regular docker-compose.yml file.

To rebuild (build and rerun changed services) from your configuration file, use this command, the path to configuration file has to be absolute

upaas-rebuild `pwd`/config.nix

This should be it.

Oh yea, one more thing, to have this persistent after reboot, add /home/<you>/.nix-profile/bin/upaas-start to cron or something.

Limits

no multi machine scaling

To do

integrate Nix rollbacks (for configurations)
