Summary
CD and GitOps provide scalable methods for further abstracting the capabilities that Helm provides, allowing deployments to be controlled by the contents of a Git repository or a remote chart repository. In this chapter, we introduced the concepts of CI/CD and GitOps and explored them using Argo CD as a solution to implementing these models in the context of Helm. Then, we learned how to install Argo CD and how to create the Application and ApplicationSet resources, which are primitives for enabling Argo CD deployments and synchronizing them with specified Helm charts and values. Finally, we learned how to deploy a Helm chart across multiple different environments.
In the next chapter, we will explore another abstraction – the Helm operator.
