Re-exports from kube-runtime Common components for building Kubernetes operators

This crate contains the core building blocks to allow users to build controllers/operators/watchers that need to synchronize/reconcile kubernetes state.

Newcomers are recommended to start with the Controller builder, which gives an opinionated starting point that should be appropriate for simple operators, but all components are designed to be usable á la carte if your operator doesn’t quite fit that mold.

Modules

• controller
  Runs a user-supplied reconciler function on objects when they (or related objects) are updated
• events
  Publishes events for objects for kubernetes >= 1.19
• finalizer
  Finalizer helper for Controller reconcilers
• reflector
  Caches objects in memory
• scheduler
  Delays and deduplicates Stream items
• utils
  Helpers for manipulating built-in streams
• wait
  Waits for objects to reach desired states
• watcher
  Watches a Kubernetes Resource for changes, with error recovery

Structs

• Config
  Accumulates all options that can be used on a Controller invocation.
• Controller
  Controller for a Resource K

Traits

• Predicate
  A predicate is a hasher of Kubernetes objects stream filtering
• WatchStreamExt
  Extension trait for streams returned by watcher or reflector

Functions

• applier
  Apply a reconciler to an input stream, with a given retry policy
• finalizer
  Reconcile an object in a way that requires cleanup before an object can be deleted.
• metadata_watcher
  Watches a Kubernetes Resource for changes continuously and receives only the metadata
• reflector
  Cache objects from a watcher() stream into a local Store
• scheduler
  Stream transformer that delays and deduplicates Stream items.
