What different Exit Codes mean?

[TheDevarshiShah]

Dear Team,

I am trying to integrate Kubelinter in my GitLab pipeline; so first of all, thank you creating this wonderful tool!

I have a query for the exit codes though.

When the Kubelinter lint fails, it gives non zero exit code (1). However, is there any other exit codes that kubelinter supports (other than 0 and 1)? And if so, what are those.

Basically I would like to design the pipeline in a manner, that when

1. there is no issues -> exit with code 0
2. there are syntactical issues -> exit with code 1 (let say)
3. there are issues which kubectl apply might not be able to find, but are logical errors -> exit with code 2 (let say)

Thanks, Devarshi.
