@iameskild what is the status of this PR? Is it ready for review

[iameskild]

@costrouc I was gonna hold off merging since we were in a freeze prior to the v0.4.0 release but I wanted to get this in so that it would remind me to return to it later. The only thing that might be worth following up on is trying to make the timeout values configurable from the qhub-config.yaml. Is that something you think would be worthwhile? Otherwise, I'm happy to see this merged.

@iameskild May we close this (as its currently a draft) and re-open once migrated to Nebari?

[iameskild]

@viniciusdc I need to wrap up this PR this week. I might request your review when I get it finished :)

[iameskild]

@pierrotsmnrd this is ready for review. This will likely need to be tested on the beta-deployment to ensure that it works. Thanks for your patience :)

[costrouc]

Will this work? Since qhub not uses /home/<username>/

[dharhas]

@iameskild @aktech Can we fix this and get it merged and deployed. I need it for a demo on Monday.

[iameskild]

@costrouc I made some changes based on the concern you had. I tested this on minikube and I am able to successfully get the username and launch a panel-serve app 🙌 let me know if you have any other questions or concerns!
