The document provides an overview of CI/CD principles and the tools involved, particularly focusing on fabric8, Kubernetes, and OpenShift. Key concepts include container architecture, CLI commands for managing containers and services, and the integration of DevOps practices. The document also highlights advantages of using Docker for lightweight virtualization and emphasizes the importance of these technologies in accelerating development workflows.

is
CI/CD?

5. CI/CD

6. Foundation

8. Architecture

9. ● Image
○ Read-only FS
○ Deploy & Share
○ Blueprint for a
container
Concepts
● Container
○ Read-write FS
○ Image Instance
○ Has a lifecycle
● Volume
○ External storage
○ Share data
○ Persist data
● Registry
○ Image Repository
Storage

10. Docker CLI
● docker search #search for images in a registry
● docker pull #downloads image from a registry
● docker images #displays existing images on a machine
● docker run #creates and runs container from an image
● docker ps #displayes all containers
● docker start/stop #starts/stops containers
● docker rm #removes containers
● docker rmi #removes images

12. Concepts
● Pod (collection of one or more Docker containers)
● Replication Controller (creates and cares about PODs)
● Service (proxy for a collection of PODs with single IP)
● Namespaces (divide cluster resources between multiple uses)
● Nodes (worker machine)
● Secret (holds sensitive information)

13. Concepts
● Labels (used to specify identifying attributes of objects)
● Volume (volume with POD’ lifecycle)
● Persistent Volumes (networked storage in the cluster)
● Persistent Volume Claim (a request for storage)
● etc

14. Architecture

15. K8s CLI
● kubectl get pods #displayes PODs
● kubectl get services #displayes services
● kubectl get rc #displayes replication controllers
● kubectl get nodes #displayes nodes
● kubectl create #creates objects
● kubectl delete #deletes objects
● kubectl edit #allows to modify resource on the server
● kubectl scale #sets a new size for RC or DC
● kubectl autoscale #auto sets a new size for RC or DC based on metrics

17. Concepts
● Build (transformation of input parameters into a resulting object)
● Image Stream (automatically performs image build on events)
● Route (exposes service by externally-reachable name)
● Template (describes a set of objects that can be parameterized and processed to
produce a list of objects for creation by OpenShift)
● Deployment Config (adds support for software deployments concept)
● Project (is a Kubernetes namespace with additional annotations)

18. Architecture

19. OpenShift CLI
● oc project #switches between projects
● oc get routes #displayes routes
● oc rsh $cnt #ssh into container
● oc new-app #creates new application
● oc new-build #creates new build
● oc deploy #views, starts, cancels, or retries a deployment
● oc rollback #reverts part of an application back to a previous deployment
● oc import-image #import Docker image from registry

21. History
● Fuse ESB (Open Source integration platform by FuseSource)
● Fabric (extension for managing many ESBs)
● Fabric8 1.x (Red Hat acquired FuseSource in 2012; Fuse ESB => JBoss Fuse; Fabric
closed; based on Zookeeper)
● Fabric8 2.x (on top of Kubernetes, 1.x become Jube - pure Java implementation of
Kubernetes API)

22. Architecture

23. Services & Tools
● Fabric8 Console (management console for Kubernetes)
● CD Pipeline (set of CI/CD and infra mgm apps baked into Docker images)
● DevOps Tools (set of tools to deal with k8s and OpenShift)
● iPaaS (set of apps to provide orchestration of messaging, API and integration
svcs)

24. Demo

25. Takeaways
- Docker is cool for light-weight v12n and simplifies things
- Kubernetes is powerful container orchestration platform
- OpenShift enhances “Build” capabilities on top of k8s
- Fabric8 enables CI/CD to shine with less effort
- Explore technologies to move faster
