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
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!
