The document discusses rapid application development through cloud and on-premises solutions using Docker, emphasizing the need for speed, simplicity, and collaboration among developers. It highlights the role of DevOps in automating deployments and testing, as well as Docker's ability to standardize application packaging and enhance deployment efficiency. Additionally, it illustrates how IBM Bluemix incorporates Docker to provide enterprise capabilities and access to a variety of services for efficient application development.
Rapid Application Development in the Cloud and On-Premises with Docker
- 1. Rapid Application Development! in the Cloud and On-Premises! with Docker ! Niklas Heidloff, IBM Bluemix Developer Advocate @nheidloff heidloff.net
- 2. Rapid Application Development! § Need for speed § Deliver new apps in days rather than months § Innovate via functional prototypes rather than UI sketches § Need for simplicity § Enable different types of developers including line of business developers to build valuable apps
- 3. New Methodologies and new Technologies! § New methodologies § Agile § Design Thinking / Minimal Viable Product § New technologies § Open Source § StackOverflow § Tools, platforms, languages
- 4. Rapid Deployment ?! § Coding is often rapid, but deployment is (mostly) not § Issue: Different target platforms with different configurations § Expanded role of developers: Not only responsible to write code but responsible for full life cycle up to the testing in production environments § Old developer excuse “it works on my machine” doesn’t count any longer
- 5. DevOps! § DevOps supports developers to automate testing and deployments through delivery pipelines § But deployments can still be challenging § Different types of applications § Different target environments
- 6. Containers to the Rescue!
- 7. Containers vs. VMs! § Lighter weight than VMs (virtual machines) graphics from docker.com
- 8. Enter Docker! § Standardizes the packaging of applications and container runtimes § Write once run everywhere § Package once deploy everywhere
- 9. Introduction to Docker! § Enabling application development efficiency, making deployment more efficient, eliminating vendor ‘lock-in’ with true portability § Open § Software § Contribution § Design § Governance
- 10. Docker Terminology! § Image § Container § Registry § Engine Cloud On Prem
- 11. Demo! § Simple Java web application on Liberty Profile § Create image locally § Run container locally
- 12. Sample Servlet!
- 13. Dockerfile!
- 14. Build Image!
- 15. Run Container!
- 17. Same Sample on Tomcat!
- 19. Docker Maven Plugin! § rhuss/docker-maven-plugin to build images and run containers § mvn docker:build § mvn docker:start § mvn docker:stop § mvn -Ddocker.removeAll docker:remove
- 20. Registries to share Images! § Docker Hub § Public § Private § Docker Trusted Registry
- 21. Docker on IBM Bluemix! § Bluemix is IBM’s application platform in the cloud based on Cloud Foundry § IBM extends and connects Docker containers to production-ready enterprise environments § IBM hosted private registry § Run containers in local datacenters or in the cloud § External IP addresses § Integrated monitoring and logging § Security readiness guidance via Vulnerability Advisor
- 22. Demo! § Push image to Bluemix § Create container on Bluemix § Monitor container
- 23. Tag Image!
- 24. Push Image!
- 26. Image Registry!
- 27. Run Container!
- 28. Running Container – Overview !
- 30. Running Container – Instances !
- 31. Running Container – Monitoring !
- 32. Running Container – Logs !
- 33. Running Container – Advanced Logs !
- 36. Automation via Delivery Pipelines! § To simplify the process to build images and run containers, delivery pipelines can be used § Different deployment strategies can be used to deploy to different target environments without downtimes
- 37. Demo! § Automate deployments via delivery pipelines
- 39. Push Change!
- 45. Bluemix Services for Docker Applications! § Bluemix allows not only the hosting of Docker applications but also provides more than 100 services to build rapidly applications without having to set up infrastructure § Services are provisioned when added to applications and can be accessed via REST APIs (plus other language bindings) with user specific credentials
- 46. Bluemix Services! § Databases § Services to build web apps § Cognitive services § Backends for mobile apps § Internet of Things § Analytics and Big Data § Access to on-prem services and data
- 47. Demo! § Leverage Bluemix services
- 48. Docker to Cloud Foundry Bridge!
- 49. Bind Services!
- 51. Bound Service with Credentials!
- 52. Sample Application accessing Credentials!
- 53. Take-Aways! § Docker containers allow the standardized packaging of applications and easy deployments to different environments § Docker is currently the de-facto container standard and is evolving into the Open Container Initiative § IBM adds enterprise capabilities for Docker images and containers § Try Docker in the cloud via the 30 days trial of Bluemix
- 54. Thank you!
