Chapter 6. Conclusion and Next Steps
In a book of this size, it would be impossible to cover every detail about continuously delivering Java applications in Docker. Instead, we have attempted to highlight core areas for consideration, and also provide several practical examples for getting started. The value of implementing continuous delivery cannot be underestimated, and the increase in speed of feedback combined within the ability to reliably and repeatedly guarantee quality is a true game changer. The flexibility provided by packaging Java applications within Docker is also not to be underestimated, and what might at first glance appear to be a strange marriage between a 20-year-old programming language and an emerging packaging and runtime format can add a lot of flexibility to building, testing, and deploying applications.
The true benefits of continuously delivering Java applications within Docker containers truly starts to emerge when these approaches and technologies are combined with a holistic approach to agility—embracing agile and lean practices at the business level, designing evolutionary architectures using patterns like microservices, developing and testing software using techniques from extreme programming (XP), deploying software to programmatically defined agile infrastructure such as cloud and modern cluster managers, and also supporting the growth of a DevOps culture and shared responsibility mindset.
