v1.4.0

[gardener-extension-provider-azure]

Action Required

• [OPERATOR] ⚠️ This version is not compatible with Gardener < v1.2. (#46, @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

• [OPERATOR] The gardener-extension-provider-azure now offers a validating webhook which checks shoot resources of type azure in the core.gardener.cloud group. Operators should register this webhook in the Garden cluster to further prevent invalid modifications on azure shoots. (#45, @timuthy)

Improvements

• [USER] Gardener Azure provider extension support now Shoot cluster which have an Azure NatGateway attached to its worker subnet. (#50, @dkistner)
• [USER] The Infrastructure deletion does now succeed in case it never created anything but the cloud provider secret does not contain the correct credentials. (#49, @rfranzke)
• [USER] The Worker deletion does now succeed in case the cloud provider credentials were changed. (#49, @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. (#40, @mvladev)
• [OPERATOR] The Azure provider now allows Gardener to restart the Cloud-Controller-Manager and the Machine-Controller-Manager (see gardener/gardener#2098 for more information). (#63, @timuthy)
• [DEVELOPER] Fix nil pointer when applying machine class chart (#51, @mvladev)

[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.

• [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)

v1.3.0

[gardener-extension-provider-azure]

Improvements

• [USER] Azure Shoot cluster can now be configured with an user assigned managed identity which can be used to authenticate to other Azure service.
