Today, let’s focus on the
“Outer Loop” The outer loop consists of the larger team
processes that your code flows through on its
way to the cluster: code reviews, integration
tests, security and compliance. It needs be
transparent and fast for developers from all
teams.

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

18. @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 !

19. @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

Step
•Runs commands within
container(builder image)
•Mounts volumes, uses env
vars
•Eg. ‘mvn test’ or ‘git clone’
Task
•A list of steps that are
executed in sequential order
•Takes inputs, outputs
parameters
Task Run
•Runs a individual Task
Pipeline
•List of tasks defined to run in
a certain order
•Takes inputs, outputs
parameters
Pipeline Run
•Runs a Pipeline

Gitops

25. @kevindubois
What is GitOps?

Treat
everything as
code
Git is the
single source
of truth
Operations
through Git
workflows
