@kevindubois Cloud-Native CI/CD Containers Built for container apps and runs on Kubernetes Designed with microservices and distributed teams in mind DevOps Serverless Runs serverless with no CI/CD engine to manage and maintain

@kevindubois Why Cloud-Native CI/CD? Traditional CI/CD Cloud-Native CI/CD Designed for Virtual Machines Designed for Containers and Kubernetes Require IT Ops for CI engine maintenance Pipeline as a service with no Ops overhead Plugins shared across CI engine Pipelines fully isolated from each other Plugin dependencies with undefined update cycles Everything lifecycled as container images No interoperability with Kubernetes resources Native Kubernetes resources Admin manages persistence Platform manages persistence Config baked into CI engine container Configured via Kubernetes ConfigMaps Declarative !

@kevindubois Tekton is a Graduated Continuous Delivery Foundation project and follows the OpenSSF best practices. Contributions from Google, Red Hat, Cloudbees, IBM, Elastic, Puppet, and many more An open-source project for providing a set of shared and standard components for building Kubernetes-style CI/CD systems https://tekton.dev

@kevindubois Part of the Tekton ecosystem A Kubernetes controller that watches TaskRun and PipelineRun resources Depending on its configuration, it does the following: ● Signing TaskRun results with user provided cryptographic keys, including TaskRuns themselves and OCI Images ● Attestation formats like intoto ● Signing with a variety of cryptographic key types and services (x509, KMS) ● Support for multiple storage backends for signature Tekton Chains

@kevindubois An in-toto attestation is authenticated metadata about one or more software artifacts, as per the SLSA Attestation Model. ● Sign OCI image ● Create signed SLSA Provenance attestation for TaskRuns and PipelineRuns https://tekton.dev/docs/chains/

@kevindubois Gitops

@kevindubois What is GitOps? Treat everything as code Git is the single source of truth Operations through Git workflows
