Chef: add node attributes automatically

Using knife exec

The best way probably

knife exec -E "nodes.find(:name => 'chef-node') { |node|  node.normal_attrs['some_key'] = 'some_value'; node.save; }"

Currently, there is an explosion of tools that aim to manage secrets for automated, cloud native infrastructure management. Daniel Somerfield did some work classifying the various approaches, but (as far as I know) no one has made a recent effort to summarize the various tools.

This is an attempt to give a quick overview of what can be found out there. The list is alphabetical. There will be tools that are missing, and some of the facts might be wrong--I welcome your corrections. For the purpose, I can be reached via @maxvt on Twitter, or just leave me a comment here.

There is a companion feature matrix of various tools. Comments are welcome in the same manner.

Add gem 'rails_12factor' to your Gemfile. This will add error logging and the ability for your app to serve static assets.
bundle
Run RAILS_ENV=production rake db:create db:migrate db:seed
Run rake secret and copy the output
From the command line: export SECRET_KEY_BASE=output-of-rake-secret
To precompile your assets, run rake assets:precompile. This will create a folder public/assets that contains all of your assets.
Run RAILS_ENV=production rails s and you should see your app.

Remember to clobber your assets (rake assets:clobber) and re-precompile (rake assets:precompile) if you make changes.
