Dagger is a solution that addresses the challenges of CI/CD operations on Kubernetes by providing a rich API and native-language SDKs for expressing CI/CD operations, as well as intelligent caching. This enables platform engineers to create efficient delivery pipelines with persistent caching, which accelerates pipeline execution and improves the overall experience for development and platform teams. The recommended architecture pattern involves a Kubernetes cluster with support nodes, runner nodes, certificates manager, runner controller, and CI runners, which can be further optimized with additional components such as node auto-scalers and cloud caching services. Dagger's persistent caching works out of the box and provides fast and reliable caching, even on ephemeral CI/CD platforms, resulting in a fast, scalable, and resource-efficient CI system.
