It still has a bunch of unnecessary features, but with the correct configuration it's possible to disable these. As a bonus, it nicely adds some extra info to the notifications (called enrichments). It's intended to run alongside prometheus, b... (more) |

A: What is a .gitkeep file? They are not a part of git the way `.gitignore` files are. It's just a convention to add empty directories to git repositories.

Mostly interested in failing pods, so notifying on certain kubernetes event types would be sufficient. This really shouldn't need an additional database like prometheus). Id... (more) |

A: Why does this work? .collect() automatic conversion to function return type You're very much on the right track. std::iter::FromIterator trait This trait is indeed what makes it work. In particular, both functions' return types implement the trait: `std::result::Result` implements it if `A` implements it.[^result] And here `A = std::Vec`. `std::Vec` implements ... (more) |

A: Do the elements of 'required' array need to be defined in 'properties' dictionary in JSON schema?
