The goal of this project is to template a modular Platform-As-A-Service system capable of Higly Available, Fault Tolerant scaling by using a variety of tools. This is strictly for lab environments and the initial testing will be done on Rasperry Pi's.
For now the script assumes that you have nodes already up and running with Docker. In the future we will add additional functionality like EC2 and Vagrant builds.
- Debian-type (apt) Linux nodes
- Docker 1.12
- Key-based SSH to root
- Scalable (can add more nodes at will)
- Highly-Available (you can reach any running nodes easily)
- Fault-Tolerant (nodes going down won't affect users' experiences)
- Replicatable (everything lives in code)
- Docker 1.12 for containers
- Keepalived for availibility
- HAProxy for load-balancing
- Docker Swarm for Service Discovery and scaling
- 2 LB's (HAProxy, KeepaliveD)
- 2 Docker manager nodes
- 4 Docker worker nodes
Add this line to your application's Gemfile:
gem 'paasinstant'And then execute:
$ bundle
Or install it yourself as:
$ gem install paasinstant
Or run the Demo executable:
$ exec/paasinstant demo/paas.json
There's an executable under exe with the basics to get you started.
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
