Kubernetes v1_30 support via k8s-openapi 0.22

Please upgrade k8s-openapi along with kube to avoid conflicts.

Unstable Stream Sharing

A more complete implementation that allows sharing watcher streams between multiple Controllers (for #1080) has been added under the unstable-runtime feature-flag in #1449 and #1483 by @mateiidavid. This represents the first usable implementation of shared streams (and replaces the older prototype part in #1470). While some changes are expected, you can check the shared_stream_controller example for a high-level overview.

What's Changed

Added

• Add shared stream interfaces by @mateiidavid in #1449
• Allow to create non-controller owner reference for resource by @Danil-Grigorev in #1475
• feat(runtime): support for owned shared streams by @mateiidavid in #1483

Changed

• Upgrade k8s-openapi to 0.22 and bump MK8SV to 1.25 by @clux in #1485

Removed

• Remove abandoned StreamSubscribe implementation by @clux in #1470

Fixed

• Include inner error message in Display for SerdeError by @XAMPPRocky in #1481
• Remove invalid uniqueItems property from CRDs when Sets are used by @sbernauer in #1484

Upgrading hyper and http to 1.0 and MSRV to 1.75.0

This release completes the hyper & http ecosystem upgrade #1351 via #1438. In particular, this change includes upgrades to http, http-body, tower-http, hyper, hyper-openssl, hyper-rustls, hyper-socks2, hyper-timeout, tame-oauth, tokio-tungstenite, tower-http, rustls, rustls-pemfile, as well as adopting the new hyper_util and http_body_util to make the change.

While this change constitutes significant internal churn (and a new kube::client::Body), our external api remains largely unchanged. Some minor changes are necessary for custom clients, and for integration testing using tower_mock. See the controller-rs upgrade pr or the examples folder in this commit for details.

Headlines

k8s-openapi 0.20 for Kubernetes v1_28

Please note upstream api removals.
As usual, upgrade k8s-openapi along with kube to avoid issues.

Default TLS stack changed to rustls

With last year's upstream changes from rustls (closing all our existing rustls issues - see #1192), this is now the better choice for security, features, and ease of building. The previous default openssl stack can still be used with default-features = false plus the openssl-tls feature.

Controller Configuration

A controller Config has been added to allow tweaking two behaviour parameters (debouncing in #1265 and concurrency limits in #1277) of the Controller. Huge thanks to @aryan9600 for his work.

Streaming Lists

The sendInitialEvents alpha feature is now supported, and is quickly testable in the pod_watcher example when using the feature gate. This will help optimise the memory profile of controllers when the feature becomes generally available. Amazing work by first time contributor @casualjim.

What's Changed

Added

• add controller::Config and debounce period to scheduler by @aryan9600 in #1265
• adds watch-list implementation without breaking changes by @casualjim in #1255
• allow configuring controller's concurrency by @aryan9600 in #1277

Changed

• Change default TLS stack to rustls-tls by @clux in #1261
• Bump k8s-openapi to 0.20.0 by @clux in #1291

Fixed

• core: omit invalid resource version parameters when doing paged requests by @goenning in #1281

• @casualjim made their first contribution in #1255
• @ymgyt made their first contribution in #1290

• @jdockerty made their first contribution in #1269

Full Changelog: 0.84.0...0.85.0

0.84.0

Highlights

Stream Improvements

On the runtime side, the Controller now delays reconciles until the main Store is ready (via a new Store helper from #1243). The stream selection for owned resources is more efficient (#1240), and the underlying watcher streams now all paginate (#1249). There are also many new WatchStreamExt helpers ( #1246 + #1228 + #1232) as a continued work towards the more customisable streams-api (#1080).

On the client-side; streaming logs are now easier to deal with as an AsyncBufRead #1235.

OIDC Refresh

Optional OIDC refreshable token support was introduced in #1229 under kube/oidc for out-of-cluster Client configuration. Previously, refresh support was limited to non-OIDC tokens from the GcpOuth provider (kube/oauth) or through arbitrary exec calls / TokenFile loading.

What's Changed

Added

• Add Predicate trait to allow combination + fallbacks by @clux in #1228
• Added refreshing OIDC ID token as an optional feature by @Razz4780 in #1229
• Add WatchStreamExt::default_backoff shorthand by @clux in #1232
• Derive PartialEq on core params structs by @danrspencer in #1237
• Track store readiness by @nightkr in #1243
• Add WatchStreamExt::modify() to modify events by @aryan9600 in #1246
• Add default pagination to watcher by @clux in #1249

Changed

• Bump MSRV from 1.63 to 1.64 by @clux in #1233
• Change Api::log_stream to return AsyncBufRead by @aryan9600 in #1235

Fixed

• Make Controller::owns use metadata_watcher internally by @clux in #1240
