Docker containers have brought great opportunities to shorten the deployment process through continuous integration and delivery of applications and microservices. This applies equally to enterprise datacenters as well as the cloud. Jussi, an experienced software architect, discusses solutions and benefits of a deeply-integrated deployment pipeline using technologies such as container management platforms, Docker containers, and the drone.io Cl tool. Jussi also demonstrates deployment of a CI/CD pipeline using container management, as well as show how to deploy a containerized application through a continuous delivery pipeline.

3. Outline
What is CD and why it matters
How can containers help
Considerations in pipeline w/ containers
Practical example
Q&A

4. Why containers?
Efficient use of resources
Application portability
Unified operations interface
Easy ´deployability´

5. “Continuous Delivery is a software
development discipline where you build
software in such a way that the software
can be released to production at any
time.”
Martin Fowler 2013

7. More precisely
“Deployability” over new features
Push button deployments
100% automation

8. Why should I care?

9. Agility matters

10. Benefits
Reduced risk
Believable progress
User feedback

11. Misconceptions
(of containers and CD)
Containers are no magic bullet
Containers don’t build CD themselves
You can do CD without containers

12. Truth
Containers can help
More controlled packaging
Environment parity

13. Pipeline
Build
Test
Deploy

14. Pipeline
Script everything
Version control everything
Yes, everything

15. Everything but secrets.

16. Pipeline - Build
Use build containers
No left-overs
Isolation

17. Pipeline - Test
Easy to spin up whole stack
Isolation
Test containers

18. Pipeline - Deploy
Throw-away containers
No host updates
Easy rollbacks

19. Pipeline - Deploy
Orchestrators help immensely
Rolling updates
Loadbalancers etc. handled

20. Pipeline – The missing bits
Perf testing
Security testing
Image scanning

21. Pipeline – Image tags
Don’t use ’latest’
Tag images uniquely
Tags can be “aliases”

22. Tools for pipelines
Drone
Jenkins
Gitlab CI
…

23. Pipeline Example

24. 1. Git Push
2. Trigger Build 3. Push Docker Image
4. Trigger Deploy
5a. Deploy to Staging 5b. Deploy to Production
Pull Docker Image

25. Drone
Docker based CI/CD platform
Easy to setup
Isolated builds
Pluggable
“Just works” - feeling

26. What is Kontena?
An Open Source container &
microservices platform.
All batteries included: container
scheduling, load balancing,
secrets vault, overlay network, …

29. Summary
Containers can bring help
… but usually need other stuff around
Use container “native” envs
