RSpec VS Capistrano

RSpec is the most popular “Behaviour Driven Development for Ruby”. RSpec v3.8.0 alone has over 193 million downloads on RubyGems. While RSpec may also be used for unit or integration tests, its download count is quite impressive. As a comparison, the most-downloaded Cucumber v3.1.2 is merely 8.8 million.

RSpec

pry and rspec are gems. You had at least 3 rubies (system, rbenv, rvm), and each ruby puts its gems in a different folder. Your rspec might be in a folder for rbenv's ruby. If you switched to rvm's ruby, then bundle exec rspec would fail because rvm's ruby can't find rbenv's gems.

RSpec defines itself as:

RSpec This is my favorite testing gem. I love how readable and well-organized the tests are.

If you don't want to go down the NFS share route then Capistrano is a useful tool if you're willing to write a little bit of ruby. It comes with some built in goodies like rollbacks. It's an oldie (pre-dockerize everything), but still useful.

You can start by deploying from your machine to simultaneously get it deploying across all your servers, then I'd consider having a CI/CD pipeline take over and run Capistrano for you.

The deployment process generally includes making the new version available, directing traffic from the old to the new version, and stopping the old versions. Capistrano has been doing this since 2006. However, what makes Kubernetes deployments better is the minimum number of pods required, and its rollout strategy minimizes or eliminates downtime. For example, a rolling update strategy can ensure new pods gradually replace old pods with configs like maxSurge and maxUnavailable. Because this is done in a declarative way, as a user or operator, you only need to ask Kubernetes to apply a given deployment and Kubernetes does the rest. Next up is the Kubernetes config map.

Capistrano

What I had considered was writing a deployment script where upon successful build in a separate folder, it'd swap out the deployed folder, similar to how Capistrano works. It has a "current" folder and it'll build in a temporary folder and then replace the symlink to a newer build.

deployer is a deployment tool written in PHP. It comes with "Zero Downtime Deployments" out of the box and can be extended by writing simple PHP code. (capistrano would be the equivalent in the Ruby world).

Capistrano, if you like Ruby.
