The guide explores how to create dynamic preview environments using Argo CD and the Pull Request Generator, allowing developers to test new features in isolation by automatically generating environments from pull requests in the application source code. This setup, which aligns with GitOps principles, ensures that each pull request results in a new namespace containing the relevant deployment, enabling developers to test their features without needing to understand the intricacies of Kubernetes or Argo CD. The process involves using a Continuous Integration (CI) system, like Codefresh, to build container images tagged with the Git hash, facilitating seamless deployments. When a pull request is merged or closed, Argo CD automatically discards the corresponding environment. The guide highlights the benefits of this approach, including the ability to track configuration differences, revert to previous versions, and manage cloud resources efficiently. Despite being simple to implement, this strategy has limitations, such as not monitoring Kubernetes manifest repositories, which will be addressed in future articles.
