Nowadays we cannot imagine development without Continuous Integration, the advance level of software engineering is Continuous Delivery. There are a lot of noise around this topic however successful implementations are still rare. In this topic I'm going to share how to implement CI/CD in simple and efficient way using Fabric8.

is
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
