v1.6.0

[gardener-extension-provider-aws]

Action Required

• [USER] The AWS extension does now support shoot clusters with Kubernetes version 1.18. You should consider the Kubernetes release notes before upgrading to 1.18. Please note that the AWS EBS CSI driver will be used for 1.18 shoots. It is compatible with the legacy volume provisioners, however, you might want to update your storage classes and volume handling accordingly. Please find more information about CSI in the official Kubernetes documentation. (#64, @rfranzke)

Improvements

• [OPERATOR] kube-controller-manageer no longer has access to blocked CIDRs. (#69, @mvladev)
• [OPERATOR] g/gardener-extensions does now require the g/[email protected]. (#57, @ialidzhikov)

[cloud-provider-aws]

Improvements

• [OPERATOR] k8s.io/legacy-cloud-providers is now updated to v1.18.0. (gardener-attic/cloud-provider-aws@87ca4e4)

[gardener-extensions]

Improvements

• [OPERATOR] Add Separate sidecar controller to save worker state under Worker.Status.State (gardener-attic/gardener-extensions#600, @vlvasilev)
  • Add Worker.Status.State restoration functionality
  • Add migration functionality
• [OPERATOR] The machine.sapcloud.io CRDs applied by the ./pkg/controller/worker package do now get a protection label for accidental deletion. See also: gardener/gardener#2066 (gardener-attic/gardener-extensions#625, @rfranzke)

[terraformer]

Action Required

• [OPERATOR] The Terraformer does now lookup the relevant data stored in ConfigMaps or Secrets live from the system instead of relying on mounted volumes. This is a breaking change as the volume mount approach does no longer work, please adapt your manifests according to the examples. The rationale behind it is to not rely on potentially stale kubelet cache while it mounts the volume which may, in rare cases, cause state loss. (gardener/terraformer#37, @rfranzke)

Improvements

• [OPERATOR] nsxt and random providers are now removed from the terraform bundle. (gardener/terraformer#38, @ialidzhikov)
• [OPERATOR] terraformer does no longer ignore the termination signals sent to PID 1. It does now send a termination signal to the terraform process itself and waits for its completion. This should prevent rare cases in which the terraformer was not storing the state of created infrastructure resources. (gardener/terraformer#36, @ialidzhikov)

v1.5.0

[gardener-extension-provider-aws]

Action Required

• [OPERATOR] ⚠️ This version is not compatible with Gardener < v1.2. (#42, @georgekuruvillak)
  • The controlplanebackup webhook is removed as of gardener/gardener#1762. The controlplaneexposure webhook that was previously targeting StatefulSets is now targeting Etcd resources of the druid.

Most notable changes

• [DEVELOPER] A new integration test for infrastructure reconciliation and deletion has been added. (#54, @rfranzke)

Improvements

• [USER] The VPC gateway endpoints provided in the infrastructure configuration are now correctly provisioned. (#54, @rfranzke)
• [USER] The Infrastructure deletion does now succeed in case it never created anything but the cloud provider secret does not contain the correct credentials. (#44, @rfranzke)
• [USER] The Worker deletion does now succeed in case the cloud provider credentials were changed. (#44, @rfranzke)
• [USER] Do not mutate kube-apiserver exposure resources which Gardener marks as managed by it with core.gardener.cloud/apiserver-exposure: gardener-managed label. (#37, @mvladev)
• [OPERATOR] The AWS provider now allows Gardener to restart the Cloud-Controller-Manager and the Machine-Controller-Manager (see gardener/gardener#2098 for more information). (#65, @timuthy)
• [OPERATOR] The eth0 interface name is no longer hard-coded, instead the non-virtual network interface names are now dynamically detected. (#50, @vpnachev)
• [OPERATOR] The infrastructure controller does no longer release the finalizer of Infrastructure CR if it cannot find a given output variables. This allows terraform destroy to be invoked even when there is no output variables in the terraform.tfstate. (#49, @ialidzhikov)
• [OPERATOR] Now it is possible to modify the gateway endpoints list networks.vpc.gatewayEndpoints after the shoot is created. (#41, @tareqhs)
• [DEVELOPER] Fix nil pointer when applying machine class chart (#46, @mvladev)

[cloud-provider-aws]

Improvements

• [OPERATOR] k8s.io/legacy-cloud-providers is now updated to v0.17.4. (gardener-attic/cloud-provider-aws#2, @ialidzhikov)

[gardener-extensions]

Improvements

• [USER] An issue in the machine reconciliation has been fixed that caused the reconciliation being stuck in some cases where a previously broken worker configuration (e.g., due to the specification of machine types that are not available in certain availability zones) has been corrected. (gardener-attic/gardener-extensions#626, @rfranzke)
• [USER] Allow force deletion of machines incase of cluster hibernation (gardener-attic/gardener-extensions#609, @prashanth26)
• [OPERATOR] An issue causing running terraformer container to leak on the Node without associated Pod resource is now fixed. This will prevent multiple containers to execute apply/destroy commands simultaneously in some cases (especially for long running terraformer Pods). (gardener-attic/gardener-extensions#605, @ialidzhikov)
• [OPERATOR] Credentials used by machine-controller-manager are now updated during worker deletion. (gardener-attic/gardener-extensions#606, @EmoinLanyu)

• [OPERATOR] Improves the machine-creation and machine-deletion flow by listing and verifying the state of the machines before actual creation and deletion. (gardener/machine-controller-manager#432, @hardikdr)
• [OPERATOR] MCM now dynamically maps the node-objects with machines if Status.Node is not set. (gardener/machine-controller-manager#432, @hardikdr)
• [OPERATOR] Sort active machines by creation timestamp (gardener/machine-controller-manager#429, @prashanth26)
• [OPERATOR] Openstack: When a Server creation ERRORs, provide formatted Fault information (gardener/machine-controller-manager#427, @zuzzas)
• [OPERATOR] Set deleteOnTermination flag to true while deleting the VMs in AWS. (gardener/machine-controller-manager#420, @prashanth26)
• [OPERATOR] Skip eviction during drain if ForceDeletePods is enabled. (gardener/machine-controller-manager#416, @amshuman-kr)
• [OPERATOR] Openstack: Print API request/response debug when verbosity is set to 6 (gardener/machine-controller-manager#412, @kayrus)
• [OPERATOR] Azure: VM deletion checks any orphan dependant resources and tries to delete them if exists. (gardener/machine-controller-manager#406, @dkistner)

Improvements

• [OPERATOR] The AWS validator only validates configured zones in the InfrastructureConfig against available zones in the referring CloudProfile when shoots are created or the zone information in InfrastructureConfig is updated. This prevent immediate breakage of already running shoots clusters whose zones were removed from the CloudProfile. (#32, @timuthy)
• [OPERATOR] The AWS validator now checks that zone orders in a shoot resources is retained (only additions are allowed). (#30, @timuthy)
• [OPERATOR] Now it is possible to define VPC Gateway Endpoints for AWS shoots. The new list "gatewayEdnpoints" inside "vpc" sections is a list endpoint service names. Each item is mapped to a vpc gateway endpoint for a service "com.amazonaws..", region being the shoot region. (#17, @tareqhs)
