5. 2 . 3 2 . 4 3 . 1 TWELVE-FACTOR APPLICATIONS
6. 3 . 2 Codebase One codebase tracked in revision control, many deploys Dependencies Explicitly declare and isolate dependencies Config Store config in the environment Backing Services Treat backing services as attached resources Build, release, run Strictly separate build and run stages Processes Execute the app as one or more stateless processes
7. 3 . 3 Port binding Export services via port binding Concurrency Scale out via the process model Disposability Maximize robustness with fast startup and graceful shutdown Dev/prod parity Keep development, staging, and production as similar as possible Logs Treat logs as event streams Admin processes Run admin/management tasks as one-off processes
8. 4 . 1 Kubernetes "Kubernetes is an open-source platform for automating deployment, scaling, and operations of application containers across clusters of hosts, providing container- centric infrastructure."
9. portable: public, private, hybrid, multi-cloud extensible: modular, pluggable, hookable, composable self-healing: auto-placement, auto-restart, auto- replication, auto-scaling
10. 4 . 2 4 . 3 Architektur
11. 5 . 1 DEIS WORKFLOW
13. 5 . 2 5 . 3 Workflow
14. 5 . 4 Architecture
15. 5 . 5 Application Structure
16. 5 . 6 Application Access Application is reachable at <application>. <cluster-base>, e.g. logmon.apps.codecentric.de Deis Controller Interface is available at deis. <cluster-base>
17. 5 . 7 Scaling deis scale web=5 worker=2
18. 5 . 8 Updating Applications Deploy application New Pods will be rolled out using Kubernetes Rolling- Upgrade Feature
19. 6 . 1 APPLICATION DEPLOYMENT
20. 6 . 2 Buildpack Deployment Code per git push übertragen Deis erstellt Archiv und rollt dieses aus
21. 6 . 3 Buildpacks Ruby Nodejs Java Gradle Grails Play Python PHP Clojure Scala Go Multi
22. 6 . 4 Demo
23. 6 . 5 Dockerfile Deployment Dockerfile erstellen Code per git push übertragen Image wird erstellt und ausgerollt
24. 6 . 6 Demo
25. 6 . 7 Docker Image Deployment Docker Image erstellen Starten: deis pull nbyl-docker- docker.bintray.io/12factor-demo:latest Continous Delivery
26. 6 . 8 Demo
27. 7 . 1 INTEROPERABILITÄT
28. 7 . 2 Aber ich brauche mehr Flexibilität! https://www.flickr.com/photos/110382334@N05/11303036263
29. 7 . 3 12 Factor Applications mit Deis Workflow Normale Applikationen mit deployen Zugriff per DNS: helm <service­name>.<namespace­name>.svc.cluster.local
30. 8 . 1 INSTALLATION
31. 8 . 2 Requirements minikube helm deis cli
32. 8 . 3 Spielwiese erstellen minikube start helmc repo add deis https://github.com/deis/charts helmc fetch deis/workflow­v2.8.0 helmc generate ­x manifests workflow­v2.8.0 helmc install workflow­v2.8.0 # some cofffee deis register http://deis.$(minikube ip).nip.io
