Quick Recap

Key points

What you learned in this chapter:

1. Docker can launch all your application’s dependencies in individual containers. This includes servers, databases, language runtimes, etc. In most cases, these will require little or no configuration.

2. Docker is cross-platform.

3. Docker can, and should, be used in your development environment. You can also use it in production systems if it’s practical to do so.

The next chapter describes Docker concepts in more detail.
