New Qk/Quik Starter Scaffold - Jekyll Gem-Packed Theme - $ quik new jekyll-theme

Hello, Starting w/ Jekyll v3.3 you can package your themes (layouts, includes, assets) into gems. To show how easy it is to add new scaffolds to quik/qk - the missing code generator / scaffolder for ruby I’ve put together a new scaffold for gem-packaged jekyll themes that mirrors/copies the $ jekyll new-theme command. Try: $ quik new jekyll-theme to get started. This will use the jekyll-theme.rb quik starter script and the quickstart/jekyll-starter-theme template (just a plain git repo). ++ If anyone tries out qk/quik, let us know what you think. ++ PS: You’re invited to add your own scaffolds (gem starters, sinatra starters, jekyll starters, etc.).

opsworks_ruby – manage Ruby deployments on AWS OpsWorks Chef 12 stack

Half a year go, AWS dropped their out-of-the-box support for Ruby applications. It is still remaining in the Chef 11 stack, but if you wish to use a new Chef 12, you are on your own. That’s where opsworks_ruby kicks in - it allows you to leverage all the goodies of AWS OpsWorks (like applications, layers, connected RDS etc.) just the way Chef 11 stack did, without any extra JSON configuration. This is a much simpler solution, than implementing your own recipes (like application_ruby for example) and keep track of all those JSONs all the time. And besides, it includes many framework, web and app servers out of the box. Read more
