All notable changes to this project are documented in this file.

1.4.0

Release date: 2024-09-27

This minor release comes with various bug fixes and improvements.

kustomize-controller in sharded deployment configuration now supports cross-shard dependency check. This allows a Kustomization to depend on other Kustomizations managed by different controller shards.

In addition, the Kubernetes dependencies have been updated to v1.31.1 and various other controller dependencies have been updated to their latest version. The controller is now built with Go 1.23.

Fixes:

  • Fix incorrect use of format strings with the conditions package. #1198

Improvements:

1.3.0

Release date: 2024-05-06

This minor release comes with new features, improvements and bug fixes.

The controller has been updated to Kustomize v5.4, please see the kubernetes-sigs/kustomize changelog for more details.

The Flux Kustomization API gains two optional fields .spec.namePrefix and .spec.nameSuffix that can be used to specify a prefix and suffix to be added to the names of all managed resources.

The controller now supports the --feature-gates=StrictPostBuildSubstitutions=true flag, when enabled the post-build substitutions will fail if a variable without a default value is declared in files but is missing from the input vars.

When using variable substitution with values that are numbers or booleans, it is now possible to covert the values to strings, for more details see the post-build documentation.

In addition, the controller dependencies have been updated to Kubernetes v1.30 and controller-runtime v0.18. Various other dependencies have also been updated to their latest version to patch upstream CVEs.

Lastly, the controller is now built with Go 1.22.

Improvements:

  • Implement name prefix/suffix transformers #1134
  • Add StrictPostBuildSubstitutions feature flag #1130
  • Document how to use numbers and booleans in post build substitutions #1129
  • Remove deprecated aad pod identity from API docs #1152
  • api: Refer condition type constants from fluxcd/pkg/apis #1144
  • Update dependencies to Kustomize v5.4.0 #1128
  • Various dependency updates #1155 #1121 #1139 #1122

Fixes:

  • Fix requeue warning introduced by controller-runtime #1090
  • Remove effectless statement #1091
  • Remove genclient:Namespaced tag #1092

1.2.2

Release date: 2024-02-01

This patch release comes with various bug fixes and improvements.

Reconciling empty directories and directories without Kubernetes manifests no longer results in an error. This regressing bug was introduced with the controller upgrade to Kustomize v5.3 and has been fixed in this patch release.

The regression due to which the namespaced objects without a namespace specified resulted in not found error instead of namespace not specified has also been fixed. And the regression due to which Roles and ClusterRoles were reconciled over and over due to the normalization of Roles and ClusterRoles has also been fixed.

In addition, the Kubernetes dependencies have been updated to v1.28.6. Various other dependencies have also been updated to their latest version to patch upstream CVEs.

Lastly, the controller is now built with Go 1.21.

Improvements:

1.2.1

Release date: 2023-12-14

This patch release comes with improvements in logging to provide faster feedback on any HTTP errors encountered while fetching source artifacts.

In addition, the status condition messages are now trimmed to respect the size limit defined by the API.

Improvements:

  • Update runtime to v0.43.3 #1031
  • Log HTTP errors to provide faster feedback #1028

1.2.0

Release date: 2023-12-11

This minor release comes with performance improvements, bug fixes and several new features.

The controller has been updated from Kustomize v5.0 to v5.3, please the see kubernetes-sigs/kustomize changelog for a more details.

Starting with this version, the controller will automatically perform a cleanup of the Pods belonging to stale Kubernetes Jobs after a force apply.

A new controller flag --override-manager has been added to extend the Field Managers disallow list. Using this flag, cluster administrators can configure the controller to undo changes made with Lens and other UI tools that directly modify Kubernetes objects on clusters.

In addition, the controller dependencies have been updated, including an update to Kubernetes v1.28. The container base image has been updated to Alpine 3.19.

Improvements:

  • Update source-controller to v1.2.2 #1024
  • build: update Alpine to 3.19 #1023
  • Update Kustomize to v5.3.0 #1021
  • Support additional Field Managers in the disallow list #1017
  • Add test for Namespace custom resource #1016
  • Update controller to Kubernetes v1.28.4 #1014
  • Disable status poller cache by default #1012
  • Tweak permissions on various created files #1005
  • Cleanup pods when recreating Kubernetes Jobs #997
  • Update SOPS to v3.8.1 #995

1.1.1

Release date: 2023-10-11

This patch release contains an improvement to retry the reconciliation of a Kustomization as soon as the source artifact is available in storage. Which is particularly useful when the source-controller has just been upgraded.

In addition, the controller can now detect immutable field errors returned by the Google Cloud k8s-config-connector admission controller and recreate the GCP custom resources annotated with kustomize.toolkit.fluxcd.io/force: Enabled.

Improvements:

  • Update fluxcd/pkg dependencies #983
  • Bump github.com/cyphar/filepath-securejoin from 0.2.3 to 0.2.4 #962

Fixes:

  • fix: Retry when artifacts are available in storage #980
  • fix: Consistent artifact fetching retry timing #978

1.1.0

Release date: 2023-08-23

This minor release comes with performance improvements, bug fixes and several new features.

The apply behaviour has been extended with two policies IfNotPresent and Ignore. To change the apply behaviour for specific Kubernetes resources, you can annotate them with:

Annotation Default Values Role
kustomize.toolkit.fluxcd.io/ssa Override - Override
- Merge
- IfNotPresent
- Ignore		 Apply policy
kustomize.toolkit.fluxcd.io/force Disabled - Enabled
- Disabled		 Recreate policy
kustomize.toolkit.fluxcd.io/prune Enabled - Enabled
- Disabled		 Delete policy

The IfNotPresent policy instructs the controller to only apply the Kubernetes resources if they are not present on the cluster. This policy can be used for Kubernetes Secrets and ValidatingWebhookConfigurations managed by cert-manager, where Flux creates the resources with fields that are later on mutated by other controllers.

This version improves the health checking with fail-fast behaviour by detecting stalled Kubernetes rollouts.

In addition, the controller now stops exporting an object's metrics as soon as the object has been deleted.

Lastly, this release introduces two controller flags:

  • The --concurrent-ssa flag sets the number of concurrent server-side apply operations performed by the controller. Defaults to 4 concurrent operations per reconciliation.
  • The --interval-jitter-percentage flag makes the controller distribute the load more evenly when multiple objects are set up with the same interval. The default of this flag is set to 5, which means that the interval will be jittered by a +/- 5% random value (e.g. if the interval is 10 minutes, the actual reconciliation interval will be between 9.5 and 10.5 minutes).

Improvements:

  • Add --concurrent-ssa flag #948
  • Add IfNotPresent and Ignore SSA policies #943
  • controller: jitter requeue interval #940
  • Enable fail-fast behavior for health checks #933
  • Bump fluxcd/pkg/ssa to improve immutable error detection #932
  • Update dependencies #939
  • Update Source API to v1.1.0 #952

Fixes:

  • Handle delete before adding finalizer #930
  • Delete stale metrics on object delete #944

1.0.1

Release date: 2023-07-10

This is a patch release that fixes spurious events emitted for skipped resources.

Fixes:

  • Exclude skipped resources from apply events #920

1.0.0

Release date: 2023-07-04

This is the first stable release of the controller. From now on, this controller follows the Flux 2 release cadence and support pledge.

Starting with this version, the build, release and provenance portions of the Flux project supply chain provisionally meet SLSA Build Level 3.

This release includes several bug fixes. In addition, dependencies have been updated to their latest version, including an update of Kubernetes to v1.27.3.

1.0.0-rc.2

Release date: 2023-05-09

This release candidate fixes secrets decryption when using Azure Key Vault.

In addition, the controller dependencies have been updated to their latest versions.

Improvements:

  • Fix SOPS azkv envCred #838
  • Update dependencies #853

1.0.0-rc.1

Release date: 2023-04-03

This release candidate promotes the Kustomization API from v1beta2 to v1. The controller now supports horizontal scaling using sharding based on a label selector.

In addition, the controller now supports Workload Identity when decrypting secrets with SOPS and Azure Vault.

Highlights

This release candidate requires the GitRepository API version v1, first shipped with source-controller v1.0.0-rc.1.

API changes

The Kustomization kind was promoted from v1beta2 to v1 (GA) and deprecated fields were removed.

A new optional field called CommonMetadata was added to the API for setting labels and/or annotations to all resources part of a Kustomization. The main difference to the Kustomize commonLabels and commonAnnotations, is that the controller sets the labels and annotations only to the top level metadata field, without patching the Kubernetes Deployment spec.template or the Service spec.selector.

The kustomizations.kustomize.toolkit.fluxcd.io CRD contains the following versions:

  • v1 (storage version)
  • v1beta2 (deprecated)
  • v1beta1 (deprecated)

Upgrade procedure

The Kustomization v1 API is backwards compatible with v1beta2, except for the following:

  • the deprecated field .spec.validation was removed
  • the deprecated field .spec.patchesStrategicMerge was removed (replaced by .spec.patches)
  • the deprecated field .spec.patchesJson6902 was removed (replaced by .spec.patches)

To upgrade from v1beta2, after deploying the new CRD and controller, set apiVersion: kustomize.toolkit.fluxcd.io/v1 in the YAML files that contain Kustomization definitions and remove the deprecated fields if any. Bumping the API version in manifests can be done gradually. It is advised to not delay this procedure as the beta versions will be removed after 6 months.

Sharding

Starting with this release, the controller can be configured with --watch-label-selector, after which only objects with this label will be reconciled by the controller.

This allows for horizontal scaling, where kustomize-controller can be deployed multiple times with a unique label selector which is used as the sharding key.

Full changelog

Improvements:

  • GA: Promote Kustomization API to kustomize.toolkit.fluxcd.io/v1 #822
  • Add common labels and annotations patching capabilities #817
  • Add reconciler sharding capability based on label selector #821
  • Support Workload Identity for Azure Vault #813
  • Verify Digest of Artifact #818
  • Move controllers to internal/controllers #820
  • build(deps): bump github.com/opencontainers/runc from 1.1.2 to 1.1.5 #824

0.35.1

Release date: 2023-03-20

This prerelease comes with a fix to error reporting. The controller will now reveal validation errors when force applying resources with immutable field changes.

In addition, the controller dependencies have been updated to their latest versions.

Improvements:

  • Update dependencies #814

0.35.0

Release date: 2023-03-08

This prerelease adds support for disabling the cache of the kstatus status poller, which is used to determine the health of the resources applied by the controller. To disable the cache, configure the Deployment of the controller with --feature-gates=DisableStatusPollerCache=true.

This may have a positive impact on memory usage on large clusters with many objects, at the cost of an increased number of API calls.

In addition, klog has been configured to log using the same logger as the rest of the controller (providing a consistent log format).

Lastly, the controller is now built using Go 1.20, and the dependencies have been updated to their latest versions.

Improvements:

  • api: update description LastAppliedRevision #798
  • Update Go to 1.20 #806
  • Update dependencies #807 #811
  • Use logger.SetLogger to also configure klog #809

0.34.0

Release date: 2023-02-17

This prerelease adds support for parsing the RFC-0005 revision format produced by source-controller >=v0.35.0.

Improvements:

  • Support RFC-0005 revision format #793
  • Update dependencies #796

0.33.0

Release date: 2023-02-01

This prerelease comes with support for recreating immutable resources (e.g. Kubernetes Jobs) by annotating or labeling them with kustomize.toolkit.fluxcd.io/force: enabled.

The caching of Secret and ConfigMap resources has been disabled to improve memory usage. To opt-out from this behavior, start the controller with: --feature-gates=CacheSecretsAndConfigMaps=true.

In addition, the controller dependencies have been updated to Kubernetes v1.26.1 and controller-runtime v0.14.2. The controller base image has been updated to Alpine 3.17 (which contains CVE fixes for OS packages).

Improvements:

  • Allow force apply to be configured in metadata #787
  • Disable caching of Secrets and ConfigMaps #789
  • build: Enable SBOM and SLSA Provenance #787
  • build: Update Alpine to 3.17 #786

  • build: update dockertest to Go Mod compatible v3 #776

0.31.0

Release date: 2022-11-18

This prerelease comes with improvements to the manifests generation component. The Kustomize overlay build logic has been factored out into github.com/fluxcd/pkg/kustomize so that both the controller and the Flux CLI (flux buid kustomization) share the same code base.

In addition, the controller dependencies have been updated to Kubernetes v1.25.4 and controller-runtime v0.13.1. The Azure Vault SDK used for secrets decryption has been updated to match the latest stable release from upstream.

Improvements:

  • Refactor: Generate manifests with flux/pkg/kustomize #763

0.30.0

Release date: 2022-10-21

This prerelease comes with new status condition named Reconciling which improves the observability for the actions performed by the controller during a reconciliation run. The Kustomization.status.conditions have been aligned with Kubernetes standard conditions and kstatus.

In addition, the controller memory usage was reduced by 90% when performing artifact operations and can now better handle the reconciliation of large sources in-parallel.

Improvements:

  • API: allow configuration of h unit for timeouts #749
  • Update dependencies #750

0.29.0

Release date: 2022-09-29

This prerelease comes with strict validation rules for API fields which define a (time) duration. Effectively, this means values without a time unit (e.g. ms, s, m, h) will now be rejected by the API server. To stimulate sane configurations, the units ns, us and µs can no longer be configured, nor can h be set for fields defining a timeout value.

In addition, the controller dependencies have been updated to Kubernetes controller-runtime v0.13.

⚠️ Breaking changes:

  • .spec.interval new validation pattern is "^([0-9]+(\\.[0-9]+)?(ms|s|m|h))+$"
  • .spec.retryInterval new validation pattern is "^([0-9]+(\\.[0-9]+)?(ms|s|m|h))+$"
  • .spec.timeout new validation pattern is "^([0-9]+(\\.[0-9]+)?(ms|s|m))+$"

Improvements:

  • api: add custom validation for v1.Duration types #731
  • Build with Go 1.19 #733
  • Update dependencies #735

Fixes:

  • Fix health checking for global objects #730

0.28.0

Release date: 2022-09-12

This prerelease comes with improvements to reconciling Kubernetes class type objects, SOPS decryption and fuzzing. In addition, the controller dependencies have been updated to Kubernetes controller-runtime v0.12.

⚠️ Breaking change: The controller logs have been aligned with the Kubernetes structured logging. For more details on the new logging structure please see: fluxcd/flux2#3051.

Improvements:

  • Align controller logs to Kubernetes structured logging #718
  • Reconcile Kubernetes class type objects in a dedicated stage #720
  • Sort SOPS masterkeys so offline decrypt methods are tried first #726
  • SOPS: Update the AWS SDK for KMS #721
  • Refactor Fuzzers based on Go native fuzzing #723
  • Fuzz optimisations #722
  • Update dependencies #724

0.27.1

Release date: 2022-08-29

This prerelease comes with panic recovery, to protect the controller from crashing when reconciliations lead to a crash.

In addition, the controller dependencies have been updated to Kubernetes v1.25.0.

Improvements:

  • Enable RecoverPanic option on reconciler #708
  • Update Kubernetes packages to v1.25.0 #714
  • Add file path to sops decryption errors #706
  • Update doc on target namespace #712

In addition, the controller has been updated to Kubernetes v1.24.3 and Kustomize v4.5.7.

Features:

  • Add support for OCIRepository sources #684

Improvements:

  • Update dependencies #704

0.26.3

Release date: 2022-07-13

This prerelease adds a retry mechanism for "not found" errors when downloading artifacts and recovers from SOPS store panics. Some dependencies have also been updated to patch upstream CVEs.

Fixes:

  • decryptor: recover from SOPS store panic #691

Improvements:

  • Retry downloading artifacts on not found errors #689
  • Update dependencies #692 #696
  • build: Upgrade to Go 1.18 #694

0.26.1

Release date: 2022-06-08

This prerelease comes with documentation improvements on how to generate image pull secrets from SOPS encrypted .dockerconfigjson files.

In addition, the controller has been updated to Kubernetes v1.24.1.

Improvements:

  • docs: Add example section and dockerconfigjson encryption #675
  • Update dependencies #676
  • Update fluxcd/pkg dependencies #677

0.26.0

Release date: 2022-06-01

This prerelease comes with support for configuring the authentication to AWS KMS, Azure Key Vault and GCP KMS on multi-tenant clusters. A tenant can create a secret in their namespace with their KMS credentials and supply it to Flux using Kustomization.spec.decryption.secretRef. For more details on how to configure SOPS decryption with KMS, see the docs.

Starting with this version, the controller conforms to the Kubernetes API Priority and Fairness. The controller detects if the server-side throttling is enabled and uses the advertised rate limits. When server-side throttling is enabled, the controller ignores the --kube-api-qps and --kube-api-burst flags.

In addition, Kustomize has been updated to v4.5.5 which comes with significant performance improvements for OpenAPI parsing.

Improvements:

  • Update Alpine to v3.16 #661
  • Update go-yaml to v3.0.0 #665
  • Update source-controller/api to v0.25.0 #671

Fixes:

  • Set digests in image override #655

0.25.0

Release date: 2022-05-03

This prerelease adds support for disallowing remote bases in Kustomize overlays using --no-remote-bases=true (default: false). When this flag is enabled on the controller, all resources must refer to local files included in the Source Artifact, meaning only the Flux Sources can affect the cluster-state. Users are encouraged to enable it on production systems for security and performance reasons.

In addition, support has been introduced for defining a KubeConfig Secret data key in the .spec.kubeConfig.SecretRef.key (default: value or value.yaml), and dependencies have been updated.

Improvements:

  • Support defining a KubeConfig Secret data key #615 #645
  • Disallow remote bases usage in Kustomize overlays #638
  • decryptor: improve detection of in and out formats for Secret data fields #644

0.24.4

Release date: 2022-04-28

This prerelease ensures we recover from Kustomize build panics to guarantee continuity of operations when running into invalid object data.

In addition, handling of file formats while decrypting Secret generator entries with SOPS has been improved to ensure encrypted files in format A can be decrypted to target format B.

Fixes:

  • Use Secret generator keys for SOPS format hint #636

Improvements:

  • generator: recover from kustomize build panics #637

0.24.3

Release date: 2022-04-22

This prerelease allows for configuring the exponential back-off retry, already introduced in other Flux controllers. It can be configured with the new flags: --min-retry-delay (default: 750ms) and --max-retry-delay (default: 15min). Previously the defaults were set to 5ms and 1000s.

Fixes:

  • Ensure generated temp dir is absolute on all OSes #630

Improvements:

  • feat: flags to configure exponential backoff retry #631
  • Update source-controller to v0.24.1 #632

0.24.2

Release date: 2022-04-21

This prerelease updates the Go golang.org/x/crypto dependency to latest to please static security analysers (CVE-2022-27191).

Fixes:

  • Update golang.org/x/crypto #628

0.24.1

Release date: 2022-04-20

This prerelease fixes a regression bug introduced in #620, which prevented remote build directories from being reachable within the FS.

Fixes:

  • generator: ensure remote build dirs can be reached #626

0.24.0

Release date: 2022-04-19

This prerelease matures the Kustomize decryptor service, which handles the actual decryption of SOPS' encrypted Secrets, and now allows decrypting file sources referenced in Kustomization files.

In addition, Kustomize now operates using our own file system implementation, and dependencies have been updated to their latest versions.

Improvements:

  • controllers: improve decryptor and add tests #619
  • controllers: use own Kustomize FS implementation #620
  • Update dependencies #621 #622

0.23.0

Release date: 2022-04-05

This prerelease adds some breaking changes around the use and handling of kubeconfigs files for remote reconciliations. Implements health checks for kubernetes jobs and updates documentation.

SOPS implementation was refactored to include various improvements and extended code coverage. Age identities are now imported once and reused multiple times, optimising CPU and memory usage between decryption operations.

Breaking changes:

  • Use of file-based KubeConfig options are now permanently disabled (e.g. TLSClientConfig.CAFile, TLSClientConfig.KeyFile, TLSClientConfig.CertFile and BearerTokenFile). The drive behind the change was to discourage insecure practices of mounting Kubernetes tokens inside the controller's container file system.
  • Use of TLSClientConfig.Insecure in KubeConfig file is disabled by default, but can enabled at controller level with the flag --insecure-kubeconfig-tls.
  • Use of ExecProvider in KubeConfig file is now disabled by default, but can enabled at controller level with the flag --insecure-kubeconfig-exec.

Improvements:

  • Add kubeconfig flags #593
  • sops: various improvements and tests #607
  • docs/spec/v1beta2: fix recommended settings typo #609
  • Implement health check for Kubernetes jobs #608
  • Update KubeConfig documentation #611

0.22.3

Release date: 2022-03-29

This prerelease fixes a compatability issue between SOPS' Azure Key Vault integration, and the controller's. In addition, Kustomize has been updated to v4.5.4 to address an issue with ConfigMap and Secret generators.

Fixes:

  • sops/azkv: ensure compatibility with upstream #604
  • Update Kustomize to v4.5.4 #606

0.22.2

Release date: 2022-03-25

This prerelease fixes a regression bug where the SOPS keyservice would not properly fall back to the default server for Azure Key Vault decryption requests.

In addition, Kustomize has been updated to v4.5.3 to address an issue with YAML anchors.

Improvements:

  • Update Kustomize to v4.5.3 #594
  • Update source-controller API to v0.22.3 #596

Fixes:

  • sops/keyservice: properly fallback to default #597

0.22.1

Release date: 2022-03-24

This prerelease fixes a regression bug where alerts are sent for every reconciliation run.

Fixes:

  • Ensure event annotations are prefixed with Group FQDN #591

0.22.0

Release date: 2022-03-21

This prerelease introduces a new annotation kustomize.toolkit.fluxcd.io/ssa: merge for allowing kustomize-controller to patch cluster addons such as CoreDNS without removing the kubectl managed fields.

The source-controller dependency was updated to version v0.22 which introduces API v1beta2 and deprecates v1beta1.

In addition, various dependencies where updated to their latest versions, and the code base was refactored to align with fluxcd/pkg/runtime v0.13 release.

Improvements:

  • Allow shared ownership of in-cluster objects applied with kubectl #581
  • Update pkg/runtime and apis/meta #575
  • Update dependencies #584
  • SOPS: Add support for Azure Key Vault credentials #495

0.21.1

Release date: 2022-02-23

This prerelease comes with a workaround for an upstream bug in Kubernetes, where the keys set in a Secret with stringData are not removed from the cluster when the keys are deleted from the manifest.

Improvements:

  • Convert stringData to data before applying Secrets #576
  • Update dependencies #574

0.21.0

Release date: 2022-02-16

This prerelease comes with support for making the Kubernetes Secrets and ConfigMaps referenced in postBuild.substituteFrom optional. When substituteFrom.optional is set to true, the controller will ignore not found errors, and will substitute the variables with their default values.

Features:

  • Tolerate absence of resources in post-build substitution #570

0.20.2

Release date: 2022-02-10

This prerelease comes with an update to the sigs.k8s.io/kustomize/api package, bringing the controller on par with the Kustomize v4.5.2 release.

Kustomize v4.5.2 contains a regression bug fix for pseudo git HTTP URLs.

Improvements:

  • Update controller to kustomize v4.5.2 #567
  • Clarify spec.path in API docs #566
  • Fix typo in API docs #564

0.20.1

Release date: 2022-02-07

This prerelease comes with an update to the sigs.k8s.io/kustomize packages, bringing the controller on par with the Kustomize v4.5.1 release.

Improvements:

  • Update controller to kustomize v4.5.1 #559

Fixes:

  • Transfer ownership of the kubectl managed fields #562

0.20.0

Release date: 2022-02-01

This prerelease comes with security improvements for multi-tenant clusters:

  • Platform admins can enforce impersonation across the cluster using the --default-service-account flag. When the flag is set, all Kustomizations, which don't have spec.serviceAccountName specified, use the service account name provided by --default-service-account=<SA Name> in the namespace of the object.
  • Platform admins can disable cross-namespace references with the --no-cross-namespace-refs=true flag. When this flag is set, Kustomizations can only refer to sources (GitRepositories and Buckets) in the same namespace as the Kustomization object, preventing tenants from accessing another tenant's repositories.

The controller container images are signed with Cosign and GitHub OIDC, and a Software Bill of Materials in SPDX format has been published on the release page.

Starting with this version, the controller deployment conforms to the Kubernetes restricted pod security standard:

  • all Linux capabilities were dropped
  • the root filesystem was set to read-only
  • the seccomp profile was set to the runtime default
  • run as non-root was enabled
  • the user and group ID was set to 65534

Breaking changes:

  • The use of new seccomp API requires Kubernetes 1.19.
  • The controller container is now executed under 65534:65534 (userid:groupid). This change may break deployments that hard-coded the user ID of 'controller' in their PodSecurityPolicy.
  • When both spec.kubeConfig and spec.ServiceAccountName are specified, the controller will impersonate the service account on the target cluster, previously the controller ignored the service account.

Features:

  • Allow setting a default service account for impersonation #550
  • Allow disabling cross-namespace references #549
  • SOPS: Add support for HashiCorp Vault token-based authentication #538

Improvements:

  • Publish SBOM and sign release artifacts #541
  • Drop capabilities, enable seccomp and enforce runAsNonRoot #539
  • docs: Add var substitution operator escape syntax #537
  • Update development documentation #540
  • Refactor Fuzz implementation #536

Fixes:

  • Revoke kubectl managed fields ownership #527
  • Ensure object are finalized under impersonation #552
  • Use patch instead of update when adding finalizers #535
  • Fix preflight validation #544
  • Fix the missing protocol for the first port in manager config #547

Release date: 2021-11-12

This prerelease comes with artifact integrity verification. During the acquisition of an artifact, kustomize-controller computes its checksum using SHA-2 and verifies that it matches the checksum advertised in the Status of the Source.

The controller dependencies has been updated to match kustomize v4.4.1.

Improvements:

  • Verify artifacts integrity #489
  • Update controller to kustomize v4.4.1 #488

0.17.0

Release date: 2021-11-09

This prerelease comes with support for ignoring changes made to in-cluster resources by annotating them with:

kustomize.toolkit.fluxcd.io/reconcile: disabled

When the kustomize.toolkit.fluxcd.io/reconcile annotation is set to disabled, the controller will no longer apply changes from source, nor will it prune the resource. To resume reconciliation, set the annotation to enabled or remove it.

The controller dependencies has been updated to match kustomize v4.4.0 which restores the usage of YAML anchors.

Breaking changes

  • Namespaced objects must contain metadata.namespace, defaulting to the default namespace is no longer supported. Setting a namespace for all objects reconciled by a Kustomization can be done with spec.targetNamespace.

  • The logs, events and alerts that report Kubernetes namespaced object changes are now using the Kind/Namespace/Name format instead of Kind/Name.

  • The minimum required version of Kubernetes has changed to:

    Kubernetes version Minimum required
    v1.16 >= 1.16.11
    v1.17 >= 1.17.7
    v1.18 >= 1.18.4
    v1.19 and later >= 1.19.0

Features and Improvements

  • Being able to wait for all the applied resources to become ready without requiring users to fill-in the health check list.
  • Improve performance (CPU, memory, network, FD usage) and reduce the number of calls to Kubernetes API by replacing kubectl execs with a specialized applier written in Go.
  • Detect and report drift between the desired state (git, s3, etc) and cluster state reliably.
  • Improve the overall observably of the reconciliation process by reporting in real-time the garbage collection and health assessment actions.
  • Reconcile empty sources including pruning of all the resources previously applied.
  • Mask secrets data in logs, events and alerts.

API changes

Additions, deprecations and removals:

  • .spec.patchesStrategicMerge deprecated in favour of .spec.patches
  • .spec.patchesJson6902 deprecated in favour of .spec.patches
  • .spec.validation deprecated and no longer used (server-side validation is implicit)
  • .spec.wait added (when enabled, will wait for all the reconciled resources to become ready)
  • .status.snapshot replaced by .status.inventory

Updating the manifests in Git to v1beta2 can be done at any time after the kustomize-controller upgrade. All users are encouraged to update the manifests as the deprecated fields will be removed when the next API version will be released.

0.14.1

Improvements:

  • Mask the Kubernetes Secrets data from dry-run and apply logs #420

0.14.0

Release date: 2021-08-26

This prerelease comes with improvements to garbage collection. When pruning is enabled, the controller will skip the deletion of objects with ownerReference.BlockOwnerDeletion=true, as they are subject to Kubernetes GC.

The controller dependencies has been updated to match kustomize v4.3.0.

Improvements:

  • Update controller to kustomize v4.3.0 #416
  • Skip garbage collection of objects with owner references #411

0.13.0

Release date: 2021-06-14

This prerelease brings the controller on a par with Kustomize v4. The Kubernetes and controller-runtime dependencies have been updated to match the Kubernetes 1.21 release.

The Kustomization API has been extended with support for generic in-line patches.

Starting with this version, the controller uses an annotation instead of a label to keep track of removed manifests from source. Please consult the garbage collection docs for more details.

Breaking changes:

  • Due to the removal of hashicorp/go-getter from Kustomize v4, the set of URLs accepted by Kustomize in the resources filed is reduced to only file system paths or values compatible with git clone. This means you can no longer use resources from archives (zip, tgz, etc).
  • YAML anchors are no longer supported in Kustomize v4, see kustomize/issues/3675 for more details.
  • Due to a bug in Kustomize v4, if you have non-string keys in your manifests, the controller will fail with json: unsupported type error.

Features:

Features:

  • Support SOPS age encryption #309

Improvements:

  • Move Kustomize patch tests to Go test suite #313
  • Detect and replace empty err output on apply #312

0.10.0

Release date: 2021-03-26

This prerelease comes with a breaking change to the leader election ID from 7593cc5d.fluxcd.io to kustomize-controller-leader-election to be more descriptive. This change should not have an impact on most installations, as the default replica count is 1. If you are running a setup with multiple replicas, it is however advised to scale down before upgrading.

Fixes:

  • Fix reconciliation retry scheduler #256

0.7.0

Release date: 2021-01-22

This is the seventh MINOR prerelease.

An optional field was added spec.retryInterval that allows users to requeue a failed reconciliation at a different interval than spec.Interval.

The LocalObjectReference from the Kubernetes core has been replaced with our own, making Name a required field. The impact of this should be limited to direct API consumers only, as the field was already required by controller logic.

Improvements:
