# Changelog

All notable changes to this project will be documented in this file.

## [Unreleased]

### Added

- Git sync: add support for CAs ([#1154]).
- Add support for specifying a `clientAuthenticationMethod` for OIDC ([#1178]).
  This was originally done in [#1158] and had been reverted in [#1170].
- Implement `Deref` for `kvp::Key` to be more ergonomic to use ([#1182]).
- Add `create_random_secret_if_not_exists` function, which create a random Secret in case it doesn't already exist.
  It notably also fixes a bug we had in trino and airflow-operator, where we created immutable Secrets,
  which lead to problems ([#1187]).

### Changed

- BREAKING: Add mandatory `provision_parts` argument to `SecretOperatorVolumeSourceBuilder::new` ([#1165]).
  It now forces the caller to make an explicit choice if the public parts are sufficient or if private
  (e.g. a certificate for the Pod) parts are needed as well. This is done to avoid accidentally requesting
  too much parts. For details see [this issue](https://github.com/stackabletech/issues/issues/547).

  Additionally, `SecretClassVolume::to_volume` and `SecretClassVolume::to_ephemeral_volume_source`
  also take the same new argument.

### Removed

- BREAKING: Remove unused `add_prefix`, `try_add_prefix`, `set_name`, and `try_set_name` associated
  functions from `kvp::Key` to disallow mutable access to inner values ([#1182]).

## [0.108.0] - 2026-03-10

### Removed

- Reverted support for specifying a `clientAuthenticationMethod` for OIDC ([#1170]).
  It can be added back after the SDP 26.3.0 release.

[#1170]: https://github.com/stackabletech/operator-rs/pull/1170

## [0.107.1] - 2026-03-10

### Added

- Add CRD established signal/helper ([#1167]).

[#1168]: https://github.com/stackabletech/operator-rs/pull/1168

## [0.107.0] - 2026-03-09

### Added

- Add support for specifying a `clientAuthenticationMethod` for OIDC ([#1158]).
- Added two new crate features: `crds` and `kube-ws` ([#1162]).

### Fixed

- BREAKING: Fix compilation failures when not enabling default features ([#1162]).
  This is achieved by removing the `clap`, `telemetry` and `versioned` features, which were previously enabled by default.
  They have been removed as the stackable-operator code actually always requires them.

[#1158]: https://github.com/stackabletech/operator-rs/pull/1158
[#1162]: https://github.com/stackabletech/operator-rs/pull/1162

## [0.106.2] - 2026-02-26

  multiple concurrent tasks/futures ([#1147]).

[#1146]: https://github.com/stackabletech/operator-rs/pull/1146

[#1121]: https://github.com/stackabletech/operator-rs/pull/1121

## [0.102.0] - 2026-01-14

### Added

- BREAKING: Add `objectOverrides` field to `ListenerSpec` ([#1136]).

### Added

- Support `objectOverrides`, a list of generic Kubernetes objects, which are merged into the objects created by the operator.
  Alongside, a `deep_merger` module was added, which takes a Kubernetes object and a list of overrides and merges them into the provided object ([#1118]).

### Changed

- Bump stackable-webhook to 0.8.0, refer to its [changelog](../stackable-webhook/CHANGELOG.md) ([#1117]).
- BREAKING: `ClusterResources` now requires the objects added to implement `DeepMerge`.
  This is very likely a stackable-operator internal change, but technically breaking ([#1118]).
- Depend on the patched version of kube-rs available at <https://github.com/stackabletech/kube-rs>,
  ensuring the operators automatically benefit from the fixes ([#1124]).

### Added

- BREAKING: Add a new CLI flag/env to disabling CRD maintenance: `--disable-crd-maintenance` ([#1085]).

### Removed

- BREAKING: Remove the Merge implementation for PodTemplateSpec ([#1087]).
  It was broken because the instance was overridden by the given defaults.
  This function is not used by the Stackable operators.

### Fixed

- Don't default the `termination_grace_period` of the `ProbeBuilder` to 0, as this is an invalid value ([#1090]).

[#1085]: https://github.com/stackabletech/operator-rs/pull/1085
[#1087]: https://github.com/stackabletech/operator-rs/pull/1087
[#1090]: https://github.com/stackabletech/operator-rs/pull/1090

- Re-export `stackable-certs` and `stackable-webhook` crates ([#1074]).
- BREAKING: Add two new required CLI arguments: `--operator-namespace` and `--operator-service-name`.
  These two values are used to construct the service name in the CRD conversion webhook ([#1066]).
- Re-export `stackable-certs` and `stackable-webhook` crates ([#1074]).

### Changed

- BREAKING: The `ResolvedProductImage` field `app_version_label` was renamed to `app_version_label_value` to match changes to its type ([#1076]).
- BREAKING: Rename two fields of the `ProductOperatorRun` struct for consistency and clarity ([#1066]):
  - `telemetry_arguments` -> `telemetry`
  - `cluster_info_opts` -> `cluster_info`
- BREAKING: Some modules have been moved into the `stackable-shared` crate, so that they can also be
  used in `stackable-certs` and `stackable-webhook` ([#1074]):
  - The module `stackable_operator::time` has moved to `stackable_operator::shared::time`
  - The module `stackable_operator::commons::secret` has moved to `stackable_operator::shared::secret`

### Fixed

- BREAKING: Fix bug where `ResolvedProductImage::app_version_label` could not be used as a label value because it can contain invalid characters.
  This is the case when referencing custom images via a `@sha256:...` hash. As such, the `product_image_selection::resolve` function is now fallible ([#1076]).

## [0.94.0] - 2025-07-10

### Added

- The default Kubernetes cluster domain name is now fetched from the kubelet API unless explicitly configured ([#1068], [#1071])
  This requires operators to have the RBAC permission to `get` `nodes/proxy` in the apiGroup "", an example RBAC rule could look like:

  ```yaml
  ---
  apiVersion: rbac.authorization.k8s.io/v1
  kind: ClusterRole
  metadata:
    name: operator-cluster-role
  rules:
    - apiGroups: [""]
      resources: [nodes/proxy]
      verbs: [get]
  ```

  In addition, they must be provided the environment variable `KUBERNETES_NODE_NAME` like this:

  ```yaml
  env:
  - name: KUBERNETES_NODE_NAME
    valueFrom:
      fieldRef:
        fieldPath: spec.nodeName
  ```

[#947]: https://github.com/stackabletech/operator-rs/pull/947

## [0.84.0] - 2025-01-16

### Added

- BREAKING: Aggregate emitted Kubernetes events on the CustomResources thanks to the new
  [kube feature](https://github.com/kube-rs/controller-rs/pull/116). Instead of reporting the same
  event multiple times it now uses `EventSeries` to aggregate these events to single entry with an
  age like `3s (x11 over 53s)` ([#938]):
  - The `report_controller_error` function now needs to be async.
  - It now takes `Recorder` as a parameter instead of a `Client`.
  - The `Recorder` instance needs to be available across all `reconcile` invocations, to ensure
    aggregation works correctly.
  - The operator needs permission to `patch` events (previously only `create` was needed).
- Add `ProductSpecificCommonConfig`, so that product operators can have custom fields within `commonConfig`.
  Also add a `JavaCommonConfig`, which can be used by JVM-based tools to offer `jvmArgumentOverrides` with this mechanism ([#931])

### Changed

- BREAKING: Bump Rust dependencies to enable Kubernetes 1.32 (via `kube` 0.98.0 and `k8s-openapi` 0.23.0) ([#938]).
- BREAKING: Append a dot to the default cluster domain to make it a FQDN and allow FQDNs when validating a `DomainName` ([#939]).

## [0.83.0] - 2024-12-03

### Added

- Added cert lifetime setter to `SecretOperatorVolumeSourceBuilder` ([#915])

### Changed

- Replace unmaintained `derivative` crate with `educe` ([#907]).
- Bump dependencies, notably rustls 0.23.15 to 0.23.19 to fix [RUSTSEC-2024-0399] ([#917]).

## [0.82.0] - 2024-11-23

### Fixed

- Fixed URL handling related to OIDC and `rootPath` with and without trailing slashes. Also added a bunch of tests ([#910]).

### Changed

- BREAKING: Made `DEFAULT_OIDC_WELLKNOWN_PATH` private. Use `AuthenticationProvider::well_known_config_url` instead ([#910]).
- BREAKING: Changed visibility of `commons::rbac::service_account_name` and `commons::rbac::role_binding_name` to
  private, as these functions should not be called directly by the operators. This is likely to result in naming conflicts
  as the result is completely dependent on what is passed to this function. Operators should instead rely on the roleBinding
  and serviceAccount objects created by `commons::rbac::build_rbac_resources` and retrieve the name from the returned
  objects if they need it ([#909]).
- Changed the names of the objects that are returned from `commons::rbac::build_rbac_resources` to not rely solely on the product
  they refer to (e.g. "nifi-rolebinding") but instead include the name of the resource to be unique per cluster
  (e.g. simple-nifi-rolebinding) ([#909]).

[#909]: https://github.com/stackabletech/operator-rs/pull/909
[#910]: https://github.com/stackabletech/operator-rs/pull/910

## [0.81.0] - 2024-11-05

### Added

- Add new `PreferredAddressType::HostnameConservative` ([#903]).

### Changed

- BREAKING: Split `ListenerClass.spec.preferred_address_type` into a new `PreferredAddressType` type. Use `resolve_preferred_address_type()` to access the `AddressType` as before ([#903]).

[#903]: https://github.com/stackabletech/operator-rs/pull/903

## [0.80.0] - 2024-10-23

### Changed

- BREAKING: Don't parse `/etc/resolv.conf` to auto-detect the Kubernetes cluster domain in case it is not explicitly configured.
  Instead the operator will default to `cluster.local`. We revert this now after some concerns where raised, we will
  create a follow-up decision instead addressing how we will continue with this ([#896]).
- Update Rust dependencies (Both `json-patch` and opentelemetry crates cannot be updated because of conflicts) ([#897]):
  - Bump `kube` to `0.96.0`,
  - `rstest` to `0.23.0` and
  - `tower-http` to `0.6.1`

### Fixed

- Fix Kubernetes cluster domain parsing from resolv.conf, e.g. on AWS EKS.
  We now only consider Kubernetes services domains instead of all domains (which could include non-Kubernetes domains) ([#895]).

[#896]: https://github.com/stackabletech/operator-rs/pull/896
[#897]: https://github.com/stackabletech/operator-rs/pull/897

## [0.79.0] - 2024-10-18

### Added

- Re-export the `YamlSchema` trait and the `stackable-shared` crate as the `shared` module ([#883]).
- BREAKING: Added `preferredAddressType` field to ListenerClass CRD ([#885]).
- BREAKING: The cluster domain (default: `cluster.local`) can now be configured in the individual
  operators via the ENV variable `KUBERNETES_CLUSTER_DOMAIN` or resolved automatically by parsing
  the `/etc/resolve.conf` file. This requires using `initialize_operator` instead of `create_client`
  in the `main.rs` of the individual operators ([#893]).

### Changed

- BREAKING: The `CustomResourceExt` trait is now re-exported from the `stackable-shared` crate. The
  trait functions use the same parameters but return a different error type ([#883]).
- BREAKING: `KeyValuePairs` (as well as `Labels`/`Annotations` via it) is now backed by a `BTreeMap`
  rather than a `BTreeSet` ([#888]).
  - The `Deref` impl now returns a `BTreeMap` instead.
  - `iter()` now clones the values.

### Fixed

- BREAKING: `KeyValuePairs::insert` (as well as `Labels::`/`Annotations::` via it) now overwrites
  the old value if the key already exists. Previously, `iter()` would return _both_ values in
  lexicographical order (causing further conversions like `Into<BTreeMap>` to prefer the maximum
  value) ([#888]).

### Removed

- BREAKING: The `CustomResourceExt` trait doesn't provide a `generate_yaml_schema` function any
  more. Instead, use the high-level functions to write the schema to a file, write it to stdout or
  use it as a `String` ([#883]).

## [0.78.0] - 2024-09-30

### Added

- Add Kerberos AuthenticationProvider ([#880]).

[#880]: https://github.com/stackabletech/operator-rs/pull/880

## [0.77.1] - 2024-09-27

### Fixed

- Fix always returning an error stating that volumeMounts are colliding. Instead move the error
  creation to the correct location within an `if` statement ([#879]).

[#879]: https://github.com/stackabletech/operator-rs/pull/879

## [0.77.0] - 2024-09-26

### Fixed

- Fix the logback configuration for logback versions from 1.3.6/1.4.6 to 1.3.11/1.4.11 ([#874]).
- BREAKING: Avoid colliding volumes and mounts by only adding volumes or mounts if they do not already exist. This makes functions such as `PodBuilder::add_volume` or `ContainerBuilder::add_volume_mount` as well as related ones fallible ([#871]).

### Changed

- BREAKING: Remove the `unique_identifier` argument from `ResolvedS3Connection::add_volumes_and_mounts`, `ResolvedS3Connection::volumes_and_mounts` and `ResolvedS3Connection::credentials_mount_paths` as it is not needed anymore ([#871]).

[#871]: https://github.com/stackabletech/operator-rs/pull/871
[#874]: https://github.com/stackabletech/operator-rs/pull/874

## [0.76.0] - 2024-09-19

### Added

- BREAKING: Add `HostName` type and use it within LDAP and OIDC AuthenticationClass as well as S3Connection ([#863]).

### Changed

- BREAKING: The TLS verification struct now resides in the `commons::tls_verification` module, instead of being placed below `commons::authentication::tls` ([#863]).
- BREAKING: Rename the `Hostname` type to `DomainName` to be consistent with RFC 1123 ([#863]).

### Fixed

- BREAKING: The fields `bucketName`, `connection` and `host` on `S3BucketSpec`, `InlinedS3BucketSpec` and `S3ConnectionSpec` are now mandatory. Previously operators errored out in case these fields where missing ([#863]).

[#863]: https://github.com/stackabletech/operator-rs/pull/863

## [0.75.0] - 2024-09-19

### Added

- Add `Hostname` and `KerberosRealmName` types extracted from secret-operator ([#851]).
- Add support for listener volume scopes to `SecretOperatorVolumeSourceBuilder` ([#858]).

### Changed

- BREAKING: `validation` module now uses typed errors ([#851]).
- Set `checkIncrement` to 5 seconds in Logback config ([#853]).
- Bump Rust dependencies and enable Kubernetes 1.31 (via `kube` 0.95.0) ([#867]).

### Fixed

- Fix the CRD description of `ClientAuthenticationDetails` to not contain internal Rust doc, but a public CRD description ([#846]).
- `StackableAffinity` fields are no longer erroneously marked as required ([#855]).
- BREAKING: `ClusterResources` will now only consider deleting objects that are marked as directly owned (via `.metadata.ownerReferences`) ([#862]).

## [0.74.0] - 2024-08-22

### Added

- Add `iter::reverse_if` helper ([#838]).
- Add two new constants `CONFIG_OVERRIDE_FILE_HEADER_KEY` and `CONFIG_OVERRIDE_FILE_FOOTER_KEY` ([#843]).

### Changed

- BREAKING: Replace `lazy_static` with `std::cell::LazyCell` (the original implementation was done in [#827] and reverted in [#835]) ([#840]).
- BREAKING: Swap priority order of role group config and role overrides in configuration merging to prioritize overrides in general ([#841]).

## [0.73.0] - 2024-08-09

### Added

- Rollout tracker for `StatefulSet` ([#833]).

### Changed

- Reverted [#827], in order to restore Rust 1.79 compatibility for now ([#835]), re-opened in ([#840]).

### Fixed

- Invalid CRD schema for `StackableAffinity` contents. This was caused by the fields being optional and defaulting to `null`, while the custom schema marked the field as required ([#836]).

[#833]: https://github.com/stackabletech/operator-rs/pull/833
[#835]: https://github.com/stackabletech/operator-rs/pull/835
[#836]: https://github.com/stackabletech/operator-rs/pull/836

## [0.72.0] - 2024-08-05

### Changed

- BREAKING: Replace `lazy_static` with `std::cell::LazyCell` ([#827], [#835], [#840]).
- BREAKING: Convert `podOverrides` and `affinity` fields to take any arbitrary
  YAML input, rather than using the underlying schema. With this change, one of
  the larger CRDs, like the Druid CRD went down in size from `2.4MB` to `288K`
  (a 88% reduction). One downside is that user input is not checked to be a
  valid `PodTemplateSpec`, `PodAffinity`, `PodAntiAffinity` and `NodeAffinity`
  any more. However, checks can be re-added by using validation webhooks if
  needed. This change should not be breaking for the user and is a preparation
  for CRD versioning. ([#821]).

[#821]: https://github.com/stackabletech/operator-rs/pull/821
[#827]: https://github.com/stackabletech/operator-rs/pull/827

## [0.71.0] - 2024-07-29

### Added

- Added support for logging to files ([#814]).

### Changed

- Changed OPA Bundle Builder Vector config to read from the new log-to-file setup ([#814]).

[#814]: https://github.com/stackabletech/operator-rs/pull/814

## [0.70.0] - 2024-07-10

### Added

- Added `ProductImage::product_version` utility function ([#817], [#818])

### Changed

- BREAKING: Bump `kube` to 0.92.0. This required changes in a unit test, because
  the `kube::runtime::watcher::Event` enum introduced new and renamed some
  variants. Also see the following additional resources ([#804]).
  - [Blog Post - Breaking Change](https://kube.rs/blog/2024/06/11/watcher-memory-improvements/#breaking-change)
  - [kube#1494](https://github.com/kube-rs/kube/pull/1494)

- Upgrade opentelemetry crates ([#811]).
- Bump rust-toolchain to 1.79.0 ([#822]).

### Fixed

- Product image selection pull request version override now only applies to pull requests ([#812]).
- OPA bundle builder logs without a log message are marked with the
  error "Message not found." instead of "Log event not parsable" ([#819]).

### Added

- Derive `strum::Display` for `LogLevel`([#805]).

[#805]: https://github.com/stackabletech/operator-rs/pull/805

## [0.69.0] - 2024-06-03

### Added

- Add functionality to convert LogLevel to an OPA log level ([#798]).
- BREAKING: Add labels to listener volume builder. `PodBuilder::add_listener_volume_by_listener_class`, `PodBuilder::add_listener_volume_by_listener_name` and `ListenerOperatorVolumeSourceBuilder::new` now require you to pass the labels for the created volumes ([#799]).

[#772]: https://github.com/stackabletech/operator-rs/pull/772
[#782]: https://github.com/stackabletech/operator-rs/pull/782

## [0.67.0] - 2024-04-25

### Changed

- Bump kube to 0.89.0 and update all dependencies ([#762]).
- BREAKING: Bump k8s compilation version to `1.29`. Also bump all dependencies.
  There are some breaking changes in k8s-openapi, e.g. PVCs now have `VolumeResourceRequirements` instead of `ResourceRequirements`,
  and `PodAffinityTerm` has two new fields `match_label_keys` and `mismatch_label_keys` ([#769]).

### Removed

- BREAKING: Remove `thiserror` dependency, and deprecated builder exports ([#761])

## [0.66.0] - 2024-03-26

### Changed

- Implement `PartialEq` for most _Snafu_ Error enums ([#757]).
- Update Rust to 1.77 ([#759])

### Fixed

[#728]: https://github.com/stackabletech/operator-rs/pull/728

## [0.62.0] - 2024-01-19

- Added `Option::as_ref_or_else` to `utils` ([#717]).
- Add `iter()` methods to `KeyValuePairs<T>`, and delegate iter() for `Labels`, and `Annotations` ([#720]).
- Implement `IntoIterator` for `KeyValuePairs<T>`, `Labels` and `Annotations` ([#720]).
- Added `ListenerOperatorVolumeSourceBuilder::build_pvc` ([#719]).

## [0.61.0] - 2024-01-15

### Added

- Add `TryFrom<[(K, V); N]>` implementation for `Annotations` and `Labels` ([#711]).
- Add `parse_insert` associated function for `Annotations` and `Labels` ([#711]).
- Add generic types for `TryFrom<BTreeMap<K, V>>` impl ([#714]).
- Add `TryFromIterator` trait, which tries to construct `Self` from an iterator. It is a falliable version of
  `FromIterator` ([#715]).
- Add `TryFromIterator` impl for `Labels` and `Annotations` ([#715]).

### Changed

- Adjust `try_insert` for `Annotations` and `Labels` slightly ([#711]).

[#715]: https://github.com/stackabletech/operator-rs/pull/715

## [0.60.1] - 2024-01-04

### Fixed

- Let `ldap::AuthenticationProvider::add_volumes_and_mounts` also add the needed TLS volumes. This functionality was removed in [#680] and causes kuttl tests to fail, as the ca-cert volume and mount where missing. This patch restores the previous behavior (of adding needed TLS volumes) ([#708]).

[#708]: https://github.com/stackabletech/operator-rs/pull/708

## [0.60.0] - 2024-01-03

### Added

- Add LDAP AuthenticationClassProvider `endpoint_url()` method so each operator doesn't have to construct it. ([#705])

[#705]: https://github.com/stackabletech/operator-rs/pull/705

## [0.59.0] - 2023-12-21 🌲

### Added

- Add `stackble_operator::kvp` module and types to allow validated construction of key/value pairs, like labels and
  annotations. Most users want to use the exported type aliases `Label` and `Annotation` ([#684]).

### Changed

- Move `stackable_operator::label_selector::convert_label_selector_to_query_string` into `kvp` module. The conversion
  functionality now is encapsulated in a new trait `LabelSelectorExt`. An instance of a `LabelSelector` can now be
  converted into a query string by calling the associated function `ls.to_query_string()` ([#684]).
- BREAKING: Remove legacy node selector on `RoleGroup` ([#652]).

[#684]: https://github.com/stackabletech/operator-rs/pull/684
[#652]: https://github.com/stackabletech/operator-rs/pull/652

## [0.58.1] - 2023-12-12

### Added

- More CRD documentation ([#697]).

[#697]: https://github.com/stackabletech/operator-rs/pull/697

## [0.58.0] - 2023-12-04

### Added

- Add `oidc::AuthenticationProvider`. This enables users to deploy a new `AuthenticationClass` for OIDC providers like
  Keycloak, Okta or Auth0 ([#680]).
- Add a common `ClientAuthenticationDetails` struct, which provides common fields and functions to specify
  authentication options on product cluster level. Additionally, the PR also adds `ClientAuthenticationConfig`,
  `oidc::ClientAuthenticationOptions`, and `ldap::ClientAuthenticationOptions` ([#680]).

### Changed

- BREAKING: Change the naming of all authentication provider structs. It is now required to import them using the
  module. So imports change from `...::authentication::LdapAuthenticationProvider` to
  `...::authentication::ldap::AuthenticationProvider` for example ([#680]).
- BREAKING: Move TLS related structs into the `tls` module. Imports need to be adjusted accordingly ([#680]).

### Fixed

- Fixed appVersion label in case container images contain a hash, such as `docker.stackable.tech/stackable/nifi@sha256:85fa483aa99b9997ce476b86893ad5ed81fb7fd2db602977eb8c42f76efc109`. Also added a test-case to ensure we support images containing hashes. This should be a rather cosmetic fix, images with hashes should have worked before anyway ([#690]).

[#690]: https://github.com/stackabletech/operator-rs/pull/690

## [0.57.0] - 2023-12-04

### Changed

- BREAKING: The `CustomResourceExt` functions now take the Operator version as an argument.
  It replaces `DOCS_BASE_URL_PLACEHOLDER` in doc strings with a link to URL base, so
  `DOCS_BASE_URL_PLACEHOLDER/druid/` turns into `https://docs.stackable.tech/home/nightly/druid/`
