Summary
In this chapter, you learned about various concepts related to GitOps. You also learned about Argo CD and how to install it on OpenShift and use it. You also built and deployed a sample application to three different namespaces to simulate the development, QA, and production environments. Finally, you learned that deploying to the local or external cluster is a similar process – you only need to change the destination server field.
Argo CD allows you to establish an efficient and robust application delivery model using GitOps, in which you ensure consistency, auditable changes, and a secure process, no matter where you are deploying your applications. And the best part is that there is no additional cost to use it since it is included in Red Hat OpenShift’s subscription. That said, if you are deploying containerized applications on OpenShift, I strongly recommend that you try OpenShift GitOps and use the concepts we explored in this chapter.
