Gosen is a Ruby library for the Grid'5000 RESTful API. It relies on the Restfully library for interacting with the API.
Currently, it allows to submit deployments that retry automatically when too many nodes failed, similarly to Katapult.
$ gem install gosen
The following example deploys the latest version of the Lenny-x64-big environment on the paramount-1 and paramount-2 nodes. If both nodes are not successfully deployed, Gosen retries again (in this case, at most 5 deployment are submitted).
#!/usr/bin/env ruby
require 'gosen'
require 'logger'
require 'restfully'
logger = Logger.new(STDOUT)
Restfully::Session.new(:base_uri => 'https://api.grid5000.fr/2.0/grid5000') do |grid, session|
site = grid.sites[:rennes]
nodes = [ 'paramount-1.rennes.grid5000.fr', 'paramount-2.rennes.grid5000.fr' ]
deployment = Gosen::Deployment.new(site, 'lenny-x64-big', nodes,
{
:logger => logger,
:max_deploy_runs => 5,
:min_deployed_nodes => nodes.length,
:ssh_public_key => File.read(File.expand_path('~/.ssh/authorized_keys'))
})
deployment.join
end
The logger allows to print information about the deployment, in a style similar to Katapult:
I, [2010-04-21T11:31:09.351803 #21673] INFO -- : Kadeploy run 1 with 2 nodes (0 already deployed, need 2 more)
I, [2010-04-21T11:37:11.817323 #21673] INFO -- : Nodes deployed: paramount-1.rennes.grid5000.fr paramount-2.rennes.grid5000.fr

- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
