Thank you! ❤️

@yuri1969 maybe it could be better to have as a configuration variable?
I don't think people will want to have a different value for the same instance?
WDYT?

@tchiotludo At first, I thought the same - to have the cluster identify itself under a name (a config property => /api/v1/configs). Then I realized this was a similar situation to a GUI DB client (think of DBeaver) where you name/label/colorize your connections locally. So it is set locally.

Would there be any other use of the name on the backend/API?

Personally, I have no preference of either choice.

...and now I've discovered the possibility of having a (quirky) environment label is already present as kestra.webserver.html-head.

There seems to be a decision bottleneck here - @tchiotludo can you check how can we move forward to get this merged?

[tchiotludo]

I didn't see other needs than the environments for this one.

I think the best can be both!

• a global configuration by default
• a setting that allow people to change it based on their needs ?
  WDTY ?

I've added the global setting and made some adjust, thanks for the contributions 👏
