Running Docker in Production - The Good, the Bad and The Ugly
- 1. Docker in Production The Good, The Bad and The Ugly Jari Kolehmainen, CTO & Co-founder
- 2. © 2016 Kontena, Inc.
- 3. Pick the Right Path
- 9. DON’T DO IT (unless you are forced)
- 10. Rent? AWS ECS Azure Container Service Google Container Engine
- 12. Rent ”I don’t want to maintain anything” Works for some use cases
- 13. Platform? Docker Swarm (the new one) Kubernetes Kontena DCOS
- 15. Platform Most features built-in Less maintenance Battle tested
- 16. Docker Engine
- 17. Docker Engine Tweak defaults Needs “janitors” Prefer container “native” hosts
- 18. Docker Engine Graphdriver of the day: overlay2 Engine plugins: run outside Keep engine & kernel up-to-date
- 19. Docker Engine 3rd parties might cause side-effects Systemd <> Overlay networks Cadvisor <> Docker mounts
- 20. CI/CD Pipeline
- 23. Pipeline Script everything Version control everything Yes, everything
- 26. Pipeline Example
- 27. 1. Git Push 2. Trigger Build 3. Push Docker Image 4. Trigger Deploy 5a. Deploy to Staging 5b. Deploy to Production Pull Docker Image
- 28. Security
- 30. Security Security patching Network access Secret management Audit
- 31. Patching Container “native” OS Configuration management Image scanning
- 32. Network Security Overlay (SDN) networks Network segments/policies Firewalls
- 33. Secret Management Keep secrets out Use platform provider solution Integrate 3rd party solution to pipeline
- 37. But why? Hosts fail Engines fail Containers fail Your app crashes
- 38. Ok, is all hope lost?
- 39. Rules for chaos Allow hosts to die Trust the scheduler Use clustered databases Outsource state if possible
- 40. Summary
- 41. Summary Prepare properly Tweak defaults Automate everything Use battle tested solutions
- 42. QA Ask and get a shirt!!!
Editor's Notes
- For many newcomers production feels a bit scary I have seen & experienced many production deploys .. And heard many things from other users First production deploy: Docker 0.6 There is no ”one true way”, but I’ll tell my tips anyway
- One of the most critical things Sometimes this path has been already chosen, bad luck
- Docker engine, Rkt Many smaller parts
- Put everything together with duct tape First weeks are fun & you learn a lot Everyone should try this, once
- After few weeks/months system looks like this, a perfectly working system You have every feature that you need, and still some duct tape for the future What if that generator dies?
- - too often afterthought
- Patch host AND your images How to detect security issues?
- Overlay can provide transparent network level security
- - platforms: Kontena Vault, Kubernetes secrets, Swarm mode upcoming secrets -> check that secrets implementation matches your requirements - 3rd party: Hashicorp Vault, Square Keywhiz
- Audit logs: some platforms provide this out-of-the-box Container logs: some platforms provide support, otherwise DIY Container logs: ELK, Splunk etc…
- Mix bleeding edge components to cluster
