Thanks @JPinkney - it's the weekend here but I'll take a look on Monday. Thanks heaps for the quick turnaround!

[itowlson]

I don't feel very qualified to comment on the code in detail, but it definitely looks like a solid approach and the implementation looks good. I'll install a local build and see if fixes the downstream problem with the k8s extension. Thanks!

[andxu]

LGTM

[itowlson]

I'm not sure if I've got something wrong in the build chain (yaml-language-server -> vscode-yaml -> vscode-kubernetes-tools) but this still doesn't seem to be working for me when I build it from source. I do still get intellisense on single documents but nothing on multi-documents.

[itowlson]

I'm not sure how to track down the problem or help give any direction given how indirect the chain is - can't think of anything except sprinkling printfs and that doesn't seem very efficient... @JPinkney let me know if there's anything I can do to help validate whether there's a problem and if so to diagnose it.

@andxu @itowlson Can you try again now, it wasn't resolving $ref properly before

[itowlson]

Looking good now! I'm using @andxu's test pod/deployment YAML and the hints and errors are looking appropriate to me. Thanks!

[andxu]

@itowlson I tested the new code and it works now

[itowlson]

@JPinkney Is there a timeframe for getting this into a release please?

[JPinkney]

@itowlson I'll try for Friday, I'm a little short on time since I'm preparing for KubeCon

[itowlson]

Terrific - thanks @JPinkney!
