Description

Hey guys! As title states, I have a reproducible example where .skyignore file looks like this

# ignore all json 
*.json

# but keep this one
!config.json

When launching the cluster, I sshed onto the node and can confirm the config.json didn't get uploaded into sky_workdir

I'm using version 0.11.1 and k8 infra.

Thank you!

Contributor guide

Research direction
Examine the .skyignore parsing logic to see how it handles negation patterns (starting with '!'). Check if the negate is processed after all other patterns or if it's incorrectly skipped.
