DevOps in a GitOps World
summary
Argues for coordinating CI-built images, ConfigMaps and secrets and dependent services as a single unit rather than promoting images per-deployment, proposing environment snapshots or whole-environment promotion on top of Argo CD and ApplicationSets. Notes existing primitives like application sets and Helm umbrella charts but claims a higher-level abstraction is missing. Describes a Red Hat internal prototype that groups related apps for holistic testing across dev→stage→prod, reports tradeoffs: better consistency and auditability versus longer, heavier test runs; upstream contribution is being considered.
