LGTM

Typescript generation fails https://github.com/devfile/api/runs/3816931403
I've rerun hoping it will pass but some work may be needed there, feel free to ask @JPinkney help

P.S.

W: The repository 'deb.nodesource.com/node_14.x stretch Release' does not have a Release file.

probably that's temporary unavailability of package repo

It looks like the CI is failing because of: nodesource/distributions#1266. Not much we can do on our side until the kubernetes client gen updates their Dockerfile. I'll open a PR there later today that will hopefully fix the issue
