Herald is a project that aims to monitor specified Kubernetes objects, and issue webhooks to a specified service based on a template string.
I am writing Herald because I had a need for this application, and because I have been looking for a legitimate project to cut my teeth on Rust. This app is an attempt to get better at writing Rust code while also providing a service that I need.
- a CRD (Watcher) is specified that lists a specific Kubernetes
kind, a labelSelector, one or more target namespaces, and finally a set of info about a webhook destination. - When Herald detects a modification to a kind, that matches the namespaces and labelselector,it will emit a webhook as specified to a remote service, e.g. slack or discord
