Transcript

1. Integrating containers in JavaScript the good, the bad, and the

   ugly

3. containers are a thing_

4. it’s easy to control them

5. if you are human_

6. what if you’re not?

7. then we use containerd - High-level runtime (runtime manager) created

   by the Open Container Initiative - Powers Docker - Created to be manipulated through code

8. not so easy for JS devs

9. Golang predominance

10. Then I came across this article_

11. What if I did this using Node.js?

12. The first attempt sometimes good, mostly bad, but always ugly

13. use child-process

14. pros - Super easy - Takes advantage of ctr’s built

    in features - Faster implementation - Can be integrated with any external API

15. so easy that I built this

16. to the code

17. cons - heavily dependent on environment - no complete control

    over the process - Limited to parsing the string outputs - Error handling is poor - Needs sudo - Input sanitizing

18. conclusion: we can integrate containers into JS

19. but I wanted a real integration

20. The second attempt mostly good, sometimes bad, kinda pretty

21. containerd was meant to be extended

22. but you need to know how to do it

23. None
24. None

25. but it is possible

26. to the code

27. pros - Proper error handling - Proper return codes -

    Allows you full control of the pipeline - Does not need to be in the same machine - Does not require sudo - Native (gRPC module)

28. cons - Requires a LOT of knowledge in containers -

    Sparse documentation both for gRPC and containerd - Harder - Might be a problem to connect to external servers - CRT certificates and so on

29. Next steps what can we do next?

30. let’s make this a good tool

31. Let’s add more knowledge to the Web!
