CAPVCD Releases

  • CAPVCD releases releases cloud-director-36.0.0

    Changes compared to v35.1.1

    Components

    • Kubernetes from v1.35.8 to v1.36.5
    • os-tooling from v1.34.0 to v1.35.0

    Apps

    • cert-exporter from v2.12.0 to v2.12.1
    • cilium from v1.5.1 to v1.6.0
    • coredns from v1.32.0 to v1.33.0
    • etcd-defrag from v1.2.10 to v1.2.12
    • network-policies from v0.2.0 to v0.3.1
    • node-exporter from v1.20.13 to v1.21.0
    • observability-bundle from v3.3.1 to v3.5.0
    • security-bundle from v2.3.0 to v2.4.0
    • teleport-kube-agent from v0.11.1 to v0.12.0

    cert-exporter v2.12.0…v2.12.1

    Fixed

    • A cert file that cannot be read no longer aborts the scan of its whole cert path. Previously one unreadable file (such as a root-only 0600 ca.crt on an AKS node, where the exporter runs as an unprivileged user) stopped the walk, silently dropping every file sorting after it from the metrics. Unreadable files are now logged and skipped individually.

    cilium v1.5.1…v1.6.0

    Changed

    • Upgrade Cilium to v1.20.1 from v1.19.7. Please review the upstream 1.20 upgrade notes before rolling this out.
    • Serve the ztunnel image from gsoci.azurecr.io/giantswarm/cilium-ztunnel instead of pulling it from upstream. Cilium v1.20 moved this image from docker.io/istio/ztunnel to quay.io/cilium/ztunnel:v1.0.0, and our mirror carries exactly that digest, so it no longer has to be allow-listed in sync/unmirrored-images.txt. Only used by encryption.type=ztunnel, which we do not support.

    Removed

    • Upstream removed these long-deprecated Helm values in v1.20. None of them are set by this chart’s defaults, and because the chart’s values.schema.json does not reject unknown keys, leftovers in existing values are silently ignored rather than rejected — check your values before upgrading:
      • encryption.strictMode.{enabled,cidr,allowRemoteNodeIdentities} → use encryption.strictMode.egress.*
      • encryption.ipsec.encryptedOverlay
      • clustermesh.enableMCSAPISupport → use clustermesh.mcsapi.enabled (MCS-API is now stable upstream)
      • clustermesh.apiserver.tls.{server,admin,remote}.{cert,key} and clustermesh.apiserver.tls.enableSecrets → enable auto-generation or pre-create the secrets
      • hubble.redact.kafka.apiKey → Kafka-aware L7 policy support and proxylib were removed upstream
      • preflight.tofqdnsPreCache → the preflight FQDN poller was removed upstream
      • hubble.ui.backend.{livenessProbe,readinessProbe}.enabled
    • sync/patches/certgen/. Cilium v1.20 ships the certgen.enforceCAValidityThroughoutLeavesDuration value and wires --ca-enforce-validity-throughout-leaves-duration into both certgen job specs itself, so the Giant Swarm patch that added them became a no-op (it detected this and skipped). The default stays true and the rendered job specs are unchanged, so two more patches drop out of diffs/.

    coredns v1.32.0…v1.33.0

    Changed

    • Update coredns image to 1.14.6.
    • Run the E2E test suites automatically on release PRs by adding .github/release-pr-body.md.

    Fixed

    • Honor the deprecated configmap.log, loadbalancePolicy and configmap.cache again. Since 1.31.0 coredns.<zone>.log, coredns.<zone>.loadbalance and coredns.<zone>.cache.success.ttl shipped defaults that shadowed them, so the old keys were silently ignored. They are now unset by default, restoring the documented fallback chain. Rendering with default values is unchanged.

    etcd-defrag v1.2.10…v1.2.12

    Changed

    • Chart: Update dependency ahrtr/etcd-defrag to v0.45.0. (#136)
    • Chart: Update dependency ahrtr/etcd-defrag to v0.44.0. (#129)

    network-policies v0.2.0…v0.3.1

    Added

    • Add keywords to Chart.yaml.
    • Declare the io.giantswarm.application.audience (all) and
    • Add optional denyEgressToIMDS policy denying pod egress to the instance metadata service. Disabled by default.
    • Add apptest-framework e2e test suite.

    Changed

    • Always exclude the karpenter and aws-load-balancer-controller namespaces from denyEgressToIMDS.
    • Move the team annotation from the legacy application.giantswarm.io/team key to

    node-exporter v1.20.13…v1.21.0

    Added

    • disableSystemdCollector value to turn the systemd collector off, mirroring the existing disableConntrackCollector and disableNvmeCollector toggles. The collector needs a D-Bus connection to the host, which is refused on nodes where AppArmor mediates D-Bus (such as AKS Ubuntu nodes running under the default containerd profile), making it fail on every scrape. Defaults to false, so behaviour is unchanged.

    observability-bundle v3.3.1…v3.5.0

    Added

    • Point kube-prometheus-stack’s control-plane ServiceMonitors at the alloy-metrics token Secret.

    Changed

    • Update alloy apps to 0.23.1 (Alloy v1.19.2).
    • Update prometheus-operator-crd to 24.0.0 (Prometheus Operator CRDs v0.94.0).
    • Update kube-prometheus-stack to 24.0.0 (chart 91.2.3, Prometheus Operator v0.94.0).
    • Values: Update Prometheus Operator CRD and Kube Prometheus Stack to v23.0.0.

    Fixed

    • KSM custom resource state: Set the Gateway API TCPRoute and UDPRoute collectors to v1, which is the version the API server serves.

    security-bundle v2.3.0…v2.4.0

    Added

    • Add e2e scenarios covering trivy-operator VulnerabilityReport creation, starboard-exporter metrics for that report, kyverno restricted PSS enforcement, and kyverno-policy-operator PolicyException translation.

    Changed

    • Update exception-recommender (app) to v0.3.0.
    • Update falco (app) to v0.13.0.
    • Update jiralert (app) to v0.1.4.
    • Update kubescape (app) to v0.1.1.
    • Update kyverno-policies (app) to v0.27.1.
    • Update policy-api (app) to v0.0.12.
    • Update starboard-exporter (app) to v1.2.15.
    • Update trivy (app) to v0.18.0.
    • Update trivy-operator (app) to v0.15.0.

    Removed

    • Remove gel (app).

    Fixed

    • Give kubescape a 15m install and upgrade timeout. It does not finish installing within Flux’s 5m default, so it failed with context deadline exceeded and then retried indefinitely.
    • Set createNamespace on every app in the bundle, so each one creates its target namespace instead of relying on another app to have created it first. Previously kubescape failed with namespaces "kubescape" not found, and the apps targeting security-bundle could only install after kyverno-policy-operator had created it.

    teleport-kube-agent v0.11.1…v0.12.0

    Changed

    • Updated teleport-kube-agent to upstream version v18.10.7.
  • CAPVCD releases releases cloud-director-35.1.1

    Changes compared to v35.0.1

    Components

    • cluster-cloud-director from v7.0.0 to v7.3.1
    • cluster from v8.0.0 to v8.3.1

    cluster v8.0.0…v8.3.1

    Added

    • Add the app.kubernetes.io/component label with the app name to the resources rendered per app, so they can be listed together.
    • Add preKubeadmCommandsTemplateName and postKubeadmCommandsTemplateName hooks under providerIntegration.controlPlane.kubeadmConfig and providerIntegration.workers.kubeadmConfig. They name a provider template that renders a YAML list of additional kubeadm commands, once for the control plane and once per node pool for workers.
    • Add internal.advancedConfiguration.kubelet.evictionHard values. Providers need them to tell autoscalers such as Karpenter how much of a node’s resources is allocatable.
    • SELinux: Add global.components.selinux.writablePolicyStore value (default true) to allow loading additional SELinux policies.

    Changed

    • Cilium: Replace the catch-all - operator: Exists toleration on the hubble-relay, hubble-ui and certgen components with an explicit list.
    • Enable the ClusterTrustBundle and ClusterTrustBundleProjection feature gates (Kubernetes 1.33+) and the PodCertificateRequest feature gate (Kubernetes 1.35+) by default on kube-apiserver, kube-controller-manager and kubelet.
    • SELinux: Keep AVC audit logs (required for SELinux policy generation).
    • SELinux: Relabel the whole filesystem except read-only /usr (previously only /etc/kubernetes).
    • SELinux: Correctly label CA certificates in /etc/ssl/certs for mounting into containers.
    • App to HR Migration: Skip v35.0.0 pre-releases and update docker-kubectl to v1.36.4.
    • Chart: Rework HelmRelease clean-up job.
  • CAPVCD releases releases cloud-director-35.0.1

    Changes compared to v34.5.0

    Components

    • cluster-cloud-director from v3.2.3 to v7.0.0
    • cluster from v5.3.2 to v8.0.0
    • Added containerd v2.3.2
    • Flatcar from v4593.2.4 to v4593.2.5
    • Kubernetes from v1.34.10 to v1.35.8
    • os-tooling from v1.33.1 to v1.34.0

    cluster-cloud-director v3.2.3…v7.0.0

    Added

    • CI: Run the full set of E2E test suites automatically on release PRs, via .github/release-pr-body.md. Towards https://github.com/giantswarm/roadmap/issues/4334
    • Add support for network.giantswarm.io/wildcard-cname-target annotation on the Cluster CR via global.connectivity.dns.wildcardCnameTarget.

    Changed

    • Chart: Migrate Apps to HelmReleases.
    • Ensure the API server address is added to the no_proxy list.
    • cert-manager: Fix version assignment.
    • Make: Fix application variable.

    Removed

    • Values: Remove dead container registry cache schema.
    • Chart: Remove unused cluster-shared library chart dependency.

    Fixed

    • Bump HelmRelease resources from the removed helm.toolkit.fluxcd.io/v2beta1 API to helm.toolkit.fluxcd.io/v2 so cluster apps render on management clusters running current Flux.
    • Fix ntpd failing permanently on boot due to systemd rate limiting (node rolling).

    cluster v5.3.2…v8.0.0

    Added

    • Add cert-manager-crossplane-resources HelmRelease.
    • Feature Gates: Add support for defining maximum Kubernetes version.
    • Apps: Add External DNS Crossplane Resources.
    • Apps: Deploy cluster-autoscaler inCluster in Azure.
    • MachineDeployment: Add CAPI autoscaler annotations (cluster-api-autoscaler-node-group-min-size/max-size) when minSize/maxSize are set on a node pool (only in Azure).
    • Apps: Add Cluster Autoscaler Crossplane Resources.
    • Control Plane: Add Kamaji control plane support with KamajiControlPlane resource, Kamaji etcd HelmRelease, automation RBAC, and cleanup jobs. (#740)

    Changed

    • Chart: Migrate Apps to HelmReleases.
    • Migrate coredns HelmRelease values to the new coredns-app zone-aware interface.
    • Rename the internal coredns control plane helper to align with the controlPlane values key.
    • Updated cert-manager to v4.0.0 and migrated the values to match the new chart’s schema.
    • Support templating on the global.apps.<name>.extraConfigs.name field.
    • Add support for AKS clusters
    • Add support for disabling the external autoscaler annotation (cluster.x-k8s.io/replicas-managed-by: "external-autoscaler") on MachinePools.
    • Refactor providerIntegration.resourcesApi.machinePoolResourcesEnabled into an object providerIntegration.resourcesApi.machinePoolResources and move externalAutoscaler under it (now providerIntegration.resourcesApi.machinePoolResources.externalAutoscaler).
    • Bump Flux OCIRepository version to v1.
    • Control Plane: Remove handling of clusterRole resources for kamaji Datastore CRs and create kamaji-etcd polex here.
    • Control Plane: Make etcd image tag configurable. (#841)
    • Chart: Require global.release.version if using Releases to give a better rendering error message.
    • Chart: Fix validation errors.
    • Configure observability-bundle with the management cluster name.
    • Apps: Skip kyverno-crds dependency for cluster-autoscaler when deployed inCluster.
    • Apps: Add cluster-probes HelmRelease to deploy ServiceMonitors for probing workload cluster API server endpoint from the management cluster. Configurable via global.apps.clusterProbes with default module http_2xx_insecure for self-signed certificates.
    • Helpers: Use .Chart.AppVersion in app.kubernetes.io/version label.
    • Cluster API: Migrate to API v1beta2.

    Removed

    • Cluster API: Remove strategy.rollingUpdate.deletePolicy from node pools.

    Fixed

    • Control Plane: Ensure components start correctly when SELinux is set to enforcing.

    Apps

    • cert-exporter from v2.10.1 to v2.12.0
    • cert-manager from v3.13.0 to v4.1.1
    • cilium from v1.4.3 to v1.5.1
    • cilium-servicemonitors from v0.1.4 to v0.2.0
    • cloud-provider-cloud-director from v0.5.0 to v0.5.2
    • coredns from v1.30.0 to v1.32.0
    • etcd-defrag from v1.2.6 to v1.2.10
    • net-exporter from v1.23.1 to v1.24.0
    • network-policies from v0.1.3 to v0.2.0
    • node-exporter from v1.20.11 to v1.20.13
    • observability-bundle from v2.8.0 to v3.3.1
    • Added rbac-bootstrap v0.3.0
    • security-bundle from v1.17.1 to v2.3.0
    • teleport-kube-agent from v0.10.8 to v0.11.1

    cert-exporter v2.10.1…v2.12.0

    Added

    • Regression tests covering the v2.11.1 metrics endpoint fix: concatenated and repeated certificates in secrets and files, and an endpoint level test asserting /metrics keeps returning 200 and serving the remaining metrics when a duplicate series is emitted.
    • ATS: End to end test for a TLS secret whose tls.crt holds a concatenated certificate chain.

    Changed

    • ATS: cert_gen now sets a certificate serial number, which defaulted to 0 for every generated certificate.
    • Go: Update dependencies.
    • Templates: Move PolicyException to kube-system namespace.
    • Build and publish a multi-arch (linux/amd64 + linux/arm64) container image. Required so the cert-exporter daemonset can run on Graviton/arm64 nodepools without exec format error.

    Fixed

    • Add a serialnumber label to the cert_exporter_not_after and cert_exporter_secret_not_after metrics so concatenated certificates no longer collide into identical series. The collision made the registry fail Gather(), which blanked out the entire /metrics endpoint (regression from v2.10.1).
    • Serve /metrics with ContinueOnError so a single problematic metric can no longer fail the whole scrape.

    cert-manager v3.13.0…v4.1.1

    Changed

    • Upgrade docker-kubectl image to support arm64 architecture
    • Updated cert-manager to upstream version v1.20.3.
    • Notes: cert-manager-edit ClusterRole no longer grants create on challenges.acme.cert-manager.io, nor create/patch/update on orders.acme.cert-manager.io.
    • Improved proxy settings by adding a proxy ConfigMap and setting upstream envFrom values for controller, webhook and cainjector.
    • Breaking: Helm values to be passed to the upstream cert-manager chart will now need to use the cert-manager path instead of root. For example, the value crds.enabled: true must now be set with cert-manager.crds.enabled: true.
    • Moved vendored chart to helm/cert-manager/charts/ and adapted sync scripts to follow new structure.

    cilium v1.4.3…v1.5.1

    Added

    • sync/verify-images.sh, run as the last step of sync/sync.sh and therefore in CI: renders the chart across four scenarios covering every image-bearing component and fails the sync unless each image is served from gsoci.azurecr.io/giantswarm/ or is explicitly listed in sync/unmirrored-images.txt. It also asserts that every configured image actually appears in a render, so a scenario that stops covering an image fails instead of silently narrowing the check. This replaces the removed patch’s fail guards, which were the only thing that made image drift visible on an upstream bump.

    Changed

    • Upgrade Cilium to v1.19.7.
    • Run the E2E test suites automatically on release PRs by adding .github/release-pr-body.md.
    • Upgrade Cilium to v1.19.6.
    • Switch Hubble TLS certificate provisioning from hubble.tls.auto.method: helm to cronJob (giantswarm#37201). The helm method minted certificates once and never renewed them, deterministically breaking hubble-relay when the leaf certs (1 year) or the CA (3 years) expired. With the cronJob method a hubble-generate-certs CronJob re-issues the leaf certificates every 4 months. On upgrade, the Helm-owned cilium-ca, hubble-server-certs and hubble-relay-client-certs secrets are deleted and re-created by a one-shot certgen job with a fresh 3-year CA; agents and hubble-relay hot-reload the new certificates without restarts.
    • Wire certgen’s --ca-enforce-validity-throughout-leaves-duration flag (new value certgen.enforceCAValidityThroughoutLeavesDuration, default true): the certgen job now fails roughly one year before the CA would no longer cover new leaf certificates, instead of silently issuing leafs that outlive the CA. certgen never rotates an existing CA on its own (cilium/certgen#500).
    • Relax hubble-relay podAffinity to preferredDuringSchedulingIgnoredDuringExecution so Karpenter can drain the last cilium-agent-bearing node during upgrades/consolidation instead of getting stuck on a required co-location with cilium.
    • Upgrade Cilium to v1.19.5.
    • Upgrade Cilium to v1.19.4.

    Removed

    • Removed the image.registry value and the sync patch behind it (roadmap#3264). The registry is now part of each image’s repository value, exactly as upstream ships it, so the chart no longer patches upstream’s cilium.image/cilium.operator.image helpers into a (list $ <image>) signature and no longer rewrites all 35 call sites with sed. helm/cilium/templates/_helpers.tpl and helm/cilium/templates/cilium-operator/_helpers.tpl are now byte-identical to upstream, and 15 template patches disappear from diffs/.

    Fixed

    • Fix four image references that were rendered as unpullable double-prefixed paths, because their repository already carried a registry while the removed patch prefixed image.registry on top: gsoci.azurecr.io/ghcr.io/spiffe/spire-server, .../spire-agent, .../docker.io/library/busybox (SPIRE mutual authentication) and .../docker.io/istio/ztunnel (encryption.type=ztunnel). All four now resolve. Latent until now because both features are disabled by default.
    • Fix rendering of the certgen job specs (hubble/tls-cronjob and clustermesh-apiserver/tls-cronjob): the image reference was not converted to the Giant Swarm cilium.image helper signature because the image-registries sync patch only processed *.yaml templates, so enabling the cronJob method failed with required list, but got "map".
    • Add NetworkPolicies allowing the hubble-generate-certs and clustermesh-apiserver-generate-certs certgen pods egress to the Kubernetes API.

    cilium-servicemonitors v0.1.4…v0.2.0

    Added

    • Add per-monitor enabled flag for the agent, hubble and operator.

    Changed

    • Switch all monitors from ServiceMonitor to PodMonitor.

    cloud-provider-cloud-director v0.5.0…v0.5.2

    Changed

    • Helpers: Replace + in version.
    • Nothing - this release is purely meant for pushing the chart to our OCI registry.

    coredns v1.30.0…v1.32.0

    Added

    • Wire up the full set of CoreDNS forward, cache, and kubernetes block parameters in the structured zone config:
      • forward: maxIdleConns, maxConnectAttempts, dohMethod, tls, tlsServername, next, nextOnNodata, failfastAllUnhealthyUpstreams, failover, resolver.
      • cache: zones, serveStale.verifyTimeout, disable.successZones, disable.denialZones.
      • kubernetes: endpoint, tls, kubeconfig, apiserverQPS, apiserverBurst, apiserverMaxInflight, namespaceLabels, fallthroughZones, multicluster, startupTimeout.

    Changed

    • Chart: Make tolerations configurable.
    • Rebuild with app-build-suite 2.2.0 (via architect orb 9.6.0): the packaged chart now carries Artifact Hub metadata (artifacthub.io/license and a Support link). No functional chart changes.
    • Standardize values.yaml comments to the # @schema / # -- (helm-docs) convention and remove section-header dividers, so values.schema.json and the chart README.md are generated from the values file. Rendered manifests are unchanged.
    • Update coredns image to 1.14.4.
    • update CoreDNS icon to light version
    • Update coredns image to 1.14.3.

    Fixed

    • Render the health directive in only the . server block. The health plugin is process-wide and can be enabled in just one Server Block, so emitting it in every zone block was invalid. ready is kept in every block (its readiness is aggregated across blocks).
    • Correct the coredns.*.cache.serveStale.refreshMode schema enum to immediate/verify (was immediate/background), matching the CoreDNS cache plugin.

    etcd-defrag v1.2.6…v1.2.10

    Changed

    • Chart: Update dependency ahrtr/etcd-defrag to v0.43.0. (#125)
    • Chart: Update dependency ahrtr/etcd-defrag to v0.42.0. (#120)
    • Chart: Update dependency ahrtr/etcd-defrag to v0.41.0. (#108)
    • Chart: Update dependency ahrtr/etcd-defrag to v0.40.0. (#94)

    net-exporter v1.23.1…v1.24.0

    Changed

    • Build and publish a multi-arch (linux/amd64 + linux/arm64) container image. Required so the net-exporter daemonset can run on Graviton/arm64 nodepools without exec format error.
    • Bump docker-kubectl init container from 1.25.4 to 1.36.0.

    network-policies v0.1.3…v0.2.0

    Added

    • Add support for AKS selector labels.

    Changed

    • Deprecated the .Values.kamaji in favour of the more generic .Values.konnectivityAgent to control the behaviour for the konnectivity-agent.

    node-exporter v1.20.11…v1.20.13

    Changed

    • CircleCI: Do not override app version.
    • Chart: Move PolicyException to kube-system namespace.

    observability-bundle v2.8.0…v3.3.1

    Added

    • Add KSM metrics for Gateway API ListenerSet and ReferenceGrant resources.
    • Add Backstage audience annotations.
    • Add managementCluster: "" as a top-level value (populated from the cluster chart via defaultValues)
    • Moves full KSM metricRelabelings ownership from kube-prometheus-stack-app into observability-bundle

    Changed

    • Values: Generate schema for Alloy PodLogs CRDs.
    • Values: Add Cilium as dependency for Alloy apps & Kube Prometheus Stack.
    • Values: Update Alloy apps to v0.21.2.
    • Update Gateway API KSM configs to v1 for Gateway, GatewayClass, HTTPRoute, GRPCRoute, TLSRoute and BackendTLSPolicy.
    • Update kube-prometheus-stack and prometheus-operator-crd to 22.0.0
    • Update alloy-app to 0.21.0
    • HelmReleases: honor the App platform priority field (1-150, default 25) on extraConfigs entries. spec.valuesFrom now reproduces the App platform merge order — all configMaps before all secrets (a secret always overrides a configMap), each kind ordered by priority around the user-config layer — preserving the App CR merge semantics after the migration. (giantswarm#36096)
    • Migrate sub-apps from App CRs to Flux HelmRelease CRs.
    • Remove ‘cluster-values’ ConfigMap reference from HelmReleases.
    • Add new alloy-podlogs-crds chart.
    • Update alloy-app to 0.20.0
    • Update dependency kube-prometheus-stack-app and prometheus-operator-crd to v21.0.0
    • Update alloy-app to 0.19.0

    Removed

    • Values: Remove unused catalog.

    rbac-bootstrap v0.3.0

    Added

    • Add io.giantswarm.application.managed chart annotation for Backstage visibility.
    • Add optional cluster-reader ClusterRole (off by default, enabled via clusterReader.enabled: true) that aggregates into the built-in view ClusterRole and grants read access (get/list/watch) on cluster-scoped resources.

    Changed

    • Migrate chart metadata annotations to OCI-compatible format.

    • Update trivy (app) to v0.15.0.
    • Update falco (app) to v0.12.0.
    • HelmReleases: honor the App platform priority field (1-150, default 25) on extraConfigs entries. spec.valuesFrom now reproduces the App platform merge order — all configMaps before all secrets (a secret always overrides a configMap), each kind ordered by priority around the user-config layer — preserving the App CR merge semantics after the migration. (giantswarm#36096)
    • Migrate sub-apps from App CRs to Flux HelmRelease CRs.
    • No longer pass the ‘cluster-values’ ConfigMap to the applications inside the bundle.
    • Update kyverno (app) to v0.24.2.

    • cilium from v1.4.3 to v1.5.1

    • security-bundle from v1.17.1 to v2.3.0
    • teleport-kube-agent from v0.10.8 to v0.11.1

    cert-exporter v2.10.1…v2.12.0

    Added

    • Regression tests covering the v2.11.1 metrics endpoint fix: concatenated and repeated certificates in secrets and files, and an endpoint level test asserting /metrics keeps returning 200 and serving the remaining metrics when a duplicate series is emitted.
    • ATS: End to end test for a TLS secret whose tls.crt holds a concatenated certificate chain.

    Changed

    • ATS: cert_gen now sets a certificate serial number, which defaulted to 0 for every generated certificate.
    • Go: Update dependencies.
    • Templates: Move PolicyException to kube-system namespace.
    • Build and publish a multi-arch (linux/amd64 + linux/arm64) container image. Required so the cert-exporter daemonset can run on Graviton/arm64 nodepools without exec format error.

    Fixed

    • Add a serialnumber label to the cert_exporter_not_after and cert_exporter_secret_not_after metrics so concatenated certificates no longer collide into identical series. The collision made the registry fail Gather(), which blanked out the entire /metrics endpoint (regression from v2.10.1).
    • Serve /metrics with ContinueOnError so a single problematic metric can no longer fail the whole scrape.

    cert-manager v3.13.0…v4.1.1

    Changed

    • Upgrade docker-kubectl image to support arm64 architecture
    • Updated cert-manager to upstream version v1.20.3.
    • Notes: cert-manager-edit ClusterRole no longer grants create on challenges.acme.cert-manager.io, nor create/patch/update on orders.acme.cert-manager.io.
    • Improved proxy settings by adding a proxy ConfigMap and setting upstream envFrom values for controller, webhook and cainjector.
    • Breaking: Helm values to be passed to the upstream cert-manager chart will now need to use the cert-manager path instead of root. For example, the value crds.enabled: true must now be set with cert-manager.crds.enabled: true.
    • Moved vendored chart to helm/cert-manager/charts/ and adapted sync scripts to follow new structure.

    cilium v1.4.3…v1.5.1

    Added

    • sync/verify-images.sh, run as the last step of sync/sync.sh and therefore in CI: renders the chart across four scenarios covering every image-bearing component and fails the sync unless each image is served from gsoci.azurecr.io/giantswarm/ or is explicitly listed in sync/unmirrored-images.txt. It also asserts that every configured image actually appears in a render, so a scenario that stops covering an image fails instead of silently narrowing the check. This replaces the removed patch’s fail guards, which were the only thing that made image drift visible on an upstream bump.

    Changed

    • Upgrade Cilium to v1.19.7.
    • Run the E2E test suites automatically on release PRs by adding .github/release-pr-body.md.
    • Upgrade Cilium to v1.19.6.
    • Switch Hubble TLS certificate provisioning from hubble.tls.auto.method: helm to cronJob (giantswarm#37201). The helm method minted certificates once and never renewed them, deterministically breaking hubble-relay when the leaf certs (1 year) or the CA (3 years) expired. With the cronJob method a hubble-generate-certs CronJob re-issues the leaf certificates every 4 months. On upgrade, the Helm-owned cilium-ca, hubble-server-certs and hubble-relay-client-certs secrets are deleted and re-created by a one-shot certgen job with a fresh 3-year CA; agents and hubble-relay hot-reload the new certificates without restarts.
    • Wire certgen’s --ca-enforce-validity-throughout-leaves-duration flag (new value certgen.enforceCAValidityThroughoutLeavesDuration, default true): the certgen job now fails roughly one year before the CA would no longer cover new leaf certificates, instead of silently issuing leafs that outlive the CA. certgen never rotates an existing CA on its own (cilium/certgen#500).
    • Relax hubble-relay podAffinity to preferredDuringSchedulingIgnoredDuringExecution so Karpenter can drain the last cilium-agent-bearing node during upgrades/consolidation instead of getting stuck on a required co-location with cilium.
    • Upgrade Cilium to v1.19.5.
    • Upgrade Cilium to v1.19.4.

    Removed

    • Removed the image.registry value and the sync patch behind it (roadmap#3264). The registry is now part of each image’s repository value, exactly as upstream ships it, so the chart no longer patches upstream’s cilium.image/cilium.operator.image helpers into a (list $ <image>) signature and no longer rewrites all 35 call sites with sed. helm/cilium/templates/_helpers.tpl and helm/cilium/templates/cilium-operator/_helpers.tpl are now byte-identical to upstream, and 15 template patches disappear from diffs/.

    Fixed

    • Fix four image references that were rendered as unpullable double-prefixed paths, because their repository already carried a registry while the removed patch prefixed image.registry on top: gsoci.azurecr.io/ghcr.io/spiffe/spire-server, .../spire-agent, .../docker.io/library/busybox (SPIRE mutual authentication) and .../docker.io/istio/ztunnel (encryption.type=ztunnel). All four now resolve. Latent until now because both features are disabled by default.
    • Fix rendering of the certgen job specs (hubble/tls-cronjob and clustermesh-apiserver/tls-cronjob): the image reference was not converted to the Giant Swarm cilium.image helper signature because the image-registries sync patch only processed *.yaml templates, so enabling the cronJob method failed with required list, but got "map".
    • Add NetworkPolicies allowing the hubble-generate-certs and clustermesh-apiserver-generate-certs certgen pods egress to the Kubernetes API.

    cilium-servicemonitors v0.1.4…v0.2.0

    Added

    • Add per-monitor enabled flag for the agent, hubble and operator.

    Changed

    • Switch all monitors from ServiceMonitor to PodMonitor.

    cloud-provider-cloud-director v0.5.0…v0.5.2

    Changed

    • Helpers: Replace + in version.
    • Nothing - this release is purely meant for pushing the chart to our OCI registry.

    coredns v1.30.0…v1.32.0

    Added

    • Wire up the full set of CoreDNS forward, cache, and kubernetes block parameters in the structured zone config:
      • forward: maxIdleConns, maxConnectAttempts, dohMethod, tls, tlsServername, next, nextOnNodata, failfastAllUnhealthyUpstreams, failover, resolver.
      • cache: zones, serveStale.verifyTimeout, disable.successZones, disable.denialZones.
      • kubernetes: endpoint, tls, kubeconfig, apiserverQPS, apiserverBurst, apiserverMaxInflight, namespaceLabels, fallthroughZones, multicluster, startupTimeout.

    Changed

    • Chart: Make tolerations configurable.
    • Rebuild with app-build-suite 2.2.0 (via architect orb 9.6.0): the packaged chart now carries Artifact Hub metadata (artifacthub.io/license and a Support link). No functional chart changes.
    • Standardize values.yaml comments to the # @schema / # -- (helm-docs) convention and remove section-header dividers, so values.schema.json and the chart README.md are generated from the values file. Rendered manifests are unchanged.
    • Update coredns image to 1.14.4.
    • update CoreDNS icon to light version
    • Update coredns image to 1.14.3.

    Fixed

    • Render the health directive in only the . server block. The health plugin is process-wide and can be enabled in just one Server Block, so emitting it in every zone block was invalid. ready is kept in every block (its readiness is aggregated across blocks).
    • Correct the coredns.*.cache.serveStale.refreshMode schema enum to immediate/verify (was immediate/background), matching the CoreDNS cache plugin.

    etcd-defrag v1.2.6…v1.2.10

    Changed

    • Chart: Update dependency ahrtr/etcd-defrag to v0.43.0. (#125)

    net-exporter v1.23.1…v1.24.0

    Changed

    • Build and publish a multi-arch (linux/amd64 + linux/arm64) container image. Required so the net-exporter daemonset can run on Graviton/arm64 nodepools without exec format error.
    • Bump docker-kubectl init container from 1.25.4 to 1.36.0.

    network-policies v0.1.3…v0.2.0

    Added

    • Add support for AKS selector labels.

    Changed

    • Update alloy-app to 0.21.0
    • HelmReleases: honor the App platform priority field (1-150, default 25) on extraConfigs entries. spec.valuesFrom now reproduces the App platform merge order — all configMaps before all secrets (a secret always overrides a configMap), each kind ordered by priority around the user-config layer — preserving the App CR merge semantics after the migration. (giantswarm#36096)
    • Migrate sub-apps from App CRs to Flux HelmRelease CRs.
    • Remove ‘cluster-values’ ConfigMap reference from HelmReleases.
    • Add new alloy-podlogs-crds chart.
    • Update alloy-app to 0.20.0
    • Update dependency kube-prometheus-stack-app and prometheus-operator-crd to v21.0.0
    • Update alloy-app to 0.19.0

    Added

    • Add io.giantswarm.application.managed chart annotation for Backstage visibility.
    • Add optional cluster-reader ClusterRole (off by default, enabled via clusterReader.enabled: true) that aggregates into the built-in view ClusterRole and grants read access (get/list/watch) on cluster-scoped resources.

    Changed
