Description

This is the repo for deploying a Sputnik demo. I can make a change!

This repository contains the roles, environments and data bags for deploying an Sputnik laptop demonstration application.

There is also a Spiceweasel (http://bit.ly/spcwsl) manifest documenting all the community cookbooks, roles, data bags and environments required for this demo.

Issues

For the cloud provider, you may need development versions of Ohai if running on an OpenStack cloud and the trunk release of knife-rackspace if using Rackspace V2.

The apt cookbook is currently from https://github.com/mattray/apt/tree/COOK-1875 but should be released shortly.

Usage

To see the commands necessary to push all of the files to the Chef server, run the following command:

spiceweasel infrastructure.yml

To actually deploy the repository to your Chef server, run the following command:

spiceweasel infrastructure.yml | sh

Demo

1. Configure the Sputnik laptop for lxc and apt-cacher-ng with the sputnik-base Role.
2. Launch an haproxy node on lxc in the sputnik Environment.
3. Launch 2 demo-app nodes on lxc in the sputnik Environment.
4. knife ssh "role:haproxy AND chef_environment:sputnik" "chef-client"
5. Connect to the haproxy node in sputnik on port 22002 to see the web UI console.
6. Connect to the haproxy node in sputnik on port 80 to see the demo-app, refresh a couple of times.
7. Launch an haproxy node in the cloud in the production Environment.
8. Launch 2 demo-app nodes in the cloud in the production Environment.
9. knife ssh "role:haproxy AND chef_environment:production" "chef-client"
10. Connect to the haproxy node in production on port 22002 to see the web UI console.
11. Connect to the haproxy node in production on port 80 to see the demo-app, refresh a couple of times.
12. Bump up the version number of the demo-app cookbook in the metadata.rb.
13. Make a change to the demo-app cookbook.
14. knife cookbook upload demo-app
15. knife ssh "recipe:demo-app" "chef-client"
16. Connect to the haproxy node in production on port 80 to see the demo-app, refresh a couple of times. Nothing happens because we pinned the cookbook version.
17. Update the sputnik environment to use the new version of the demo-app cookbook.
18. knife environment from file sputnik.rb
19. knife ssh "recipe:demo-app AND chef_environment:sputnik" "chef-client"
20. Connect to the haproxy node in sputnik on port 80 to see the new demo-app, refresh a couple of times.
21. Fire up 10 more demo-app boxes in the production environment.
22. Update the sputnik environment to use the new version of the demo-app cookbook.
23. knife ssh "chef_environment:production" "chef-client"
24. Connect to the haproxy node in production on port 22002 to see the web UI console.
25. Connect to the haproxy node in production on port 80 to see the demo-app, refresh a couple of times.

Environments

The environments in this repo lock the versions of the cookbooks and override attributes used to differentiate sputnik laptop development environment from the production environment.

Roles

base

Recipes for every machine deployed. Attempts to use apt::cacher-client.

sputnik-base

Sets up the Sputnik laptop with lxc and apt-cacher-ng (for use by the lxc VMs).

haproxy

The demo application sits behind the software load balancer haproxy.

Cookbooks

With the exception of the demo-app cookbook, the cookbooks used by this repository are all

demo-app

Trivial html page behind apache2 that renders the names of the machines to demonstrate the haproxy integration.
