datumctl not approachable for a naïve user.

[ecv]

I am an infrastructure engineer of long experience. To me, datumctl feels weird and unapproachble.

Here's a log of my attempt to use it. Summary of issues:

• running without a login produces a stack trace bomb; the user should never, ever see one of these
• i am told to 'login' but 'login' is not a functional verb, produces same error message
• '--help' is a forty-year-old GNU standard, doesn't work, must work
• 'help' is the oft-seen equivalent, and also does not work

These are usability-blocking errors, as the user cannot discover a path forward.

Hello! Thanks @ecv to report your issues. I think they all make a lot of sense. I will work at each of them!

Can you report the stack trace as well? We know there is an issue with token refresh but for the nature of the issue it takse some time to reproduce. I feel like this is a different one.

i am told to 'login' but 'login' is not a functional verb, produces same error message

Sounds like something we can fix for sure

Related to help and --help we are trying to be as compliant as possible to what kubectl offers since a lot of what datum produces is somehow following the Kubernetes way of doing things. Your report allowed me to realize that we have run authentication at the wrong time I think because technically both --help and help work, but authentication runs too early, and it practices it makes authentication requited. I did not notice that, but it is something to fix for sure.

I think many of the bugs related to this issue should be fixed. @ecv do you mind doubling check?
I am sure there are other bugs but those should work as expected now
