Rendered Manifests and OCI in GitOps Workflows

Learn about the intersection of rendered manifests patterns and OCI (Open Container Initiative) in GitOps workflows through this 23-minute conference talk by Christian Hernandez, GitOps Advocate, presented at a CNCF event. Explore how GitOps principles address visibility and collaboration challenges in Kubernetes by emphasizing declarative desired states and continuous reconciliation. Discover the dilemma created by configuration tools like Helm and Kustomize in GitOps workflows, where abstractions become central but Argo CD's runtime mutations can obscure the actual impact on deployed manifests. Understand the Rendered Manifests pattern (also known as Hydration) as a solution to remove obfuscation and provide an immutable source of truth. Examine how the addition of OCI support in Argo CD v3.1 enables users to store manifests using OCI and its impact on the Rendered Manifests pattern. Gain insights into various patterns combining OCI with rendered manifests, including what works effectively, what doesn't work, and critical considerations when adopting OCI in your Rendered Manifests workflows.
