Rapid Application Development with Docker
- 1. Niklas Heidloff, IBM Bluemix Developer Advocate @nheidloff heidloff.net Rapid Application Development in the Cloud and On-Premises with Docker !
- 9. Rapid Application Development! § Need for speed and need for simplicity § New methodologies and technologies make the core coding fast and simple
- 10. 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
- 11. 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 § Containers to the Rescue
- 12. Containers vs. VMs! § Lighter weight than VMs (virtual machines)
- 13. Enter Docker! § Standardizes the packaging of applications and container runtimes § Write once run everywhere
- 14. Sample Servlet!
- 15. Dockerfile!
- 16. Build Image!
- 17. Run Container!
- 19. Registries to share Images! § Docker Hub § Public § Private § Docker Trusted Registry
- 20. 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
- 21. Tag Image!
- 22. Push Image!
- 24. Image Registry!
- 25. Run Container!
- 26. Running Container – Overview !
- 28. Running Container – Instances !
- 29. Running Container – Monitoring !
- 30. Running Container – Logs !
- 31. Running Container – Advanced Logs !
- 34. 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
- 36. Push Change!
- 44. REST Controller!
- 46. Dockerfile!
- 47. MongoDB URI!
- 48. Docker Compose!
- 51. UrbanCode Build and Deploy!
- 52. IBM UrbanCode Build and Deploy!
- 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 added enterprise capabilities for Docker images and containers § Try Docker in the cloud via the 30 days trial of Bluemix
