Where design patterns meet CI/CD
In this section, we will explore the basics of design patterns in general, which gives you a good foundation for the following sections of this chapter, where we will focus more on the CI/CD part of design patterns.
Design patterns can help enforce CI/CD pipelines by providing guidance on how to structure code, manage dependencies, handle errors, and perform software testing. Design patterns and CI/CD serve the same purpose of improving the efficiency and quality of software development. For example, the adapter pattern can be used to combine different tools or services in the pipeline, the Observer pattern can be used to notify various stakeholders of the pipeline status, and the Strategy pattern can be used to encapsulate different deployment algorithms, such as blue-green, canary, or rolling, and select them at runtime.
Conversely, CI/CD may also influence the selection of design patterns by imposing specific code constraints or requirements...
