There was a time when deploying software was an event, a ceremony because of the difficulty that was required to keep this consistency. Teams spent a lot of time making the destination environments run the software as the source environment. They thereafter prayed that the gods kept the software running perfectly in production as in development.<\/p>\n
With containers, deployments are more frequent because we package our applications with their libraries as a unit making them portable thereby helping us maintain consistency and reliability when moving software between environments. For developers, this is improved productivity, portability and ease of scaling.<\/p>\n
Because of this portability, containers have become the universal language of the cloud allowing us to move software from one cloud to another without much trouble.<\/p>\n
In this article, I will discuss two major concepts to note while working with containers in Ruby. I will discuss how to create small container images and how to test them.<\/p>\n
