v1.7.5

Changelog since v1.7.4

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

• Update operating-system-manager to v1.3.6. The latest Ubuntu 22.04 images on Azure have modified the configuration for cloud-init and how it accesses its datasource in Azure, in a breaking way. If you're having an Azure cluster, it's required to refresh your machines with the latest provided OSPs to ensure that a system-wide package update doesn't result in broken machines. (#3171, @xrstf)

Changes by Kind

Bug or Regression

• Do not put multiple identical tolerations on the CoreDNS deployment (#3299, @kubermatic-bot)
• Load the CA bundle before any addon installations to resolve issues with untrusted TLS connections in environments with self-signed cerificates (#3246, @kubermatic-bot)

Updates

machine-controller

• Update machine-controller to 1.57.9. This update includes support for IMDSv2 API on AWS for the worker nodes managed by machine-controller (#3324, @xrstf)

Terraform Configs

v1.8.1

Changelog since v1.8.0

Changes by Kind

Feature

• Add support for Kubernetes 1.30 (#3215, @kubermatic-bot)
• Refactor the cluster upgrade process to adhere to the Kubernetes recommendations by updating ConfigMaps used by Kubeadm instead of providing the full config to Kubeadm itself. This change should not have any effect to cluster upgrades, but if you encounter any issue, please create an issue in the KubeOne repository (#3253, @kubermatic-bot)
• KubeOne now runs kubeadm upgrade apply without the --certificate-renewal=true flag. This change should not have any effect to the upgrade process, but if you discover any issue, please create a new issue in the KubeOne repository (#3242, @kubermatic-bot)
• Add default VolumeSnapshotClass for all supported providers as part of the default-storage-class addon (#3275, @kubermatic-bot)

Bug or Regression

• Fix snapshot-webhook admitting non-supported objects (VolumeSnapshots and VolumeSnapshotContents). This fixes an issue that caused inability to create new VolumeSnapshots (#3275, @kubermatic-bot)
• Ensure apparmor-utils package is installed on Ubuntu as it's required for kubelet to function properly (#3235, @kubermatic-bot)
• Load the CA bundle before any addon installations to resolve issues with untrusted TLS connections in environments with self-signed certificates (#3247, @kubermatic-bot)
• Fix deletion issues for local Helm charts (#3268, @kubermatic-bot)

v1.8.0

We're happy to announce a new KubeOne minor release — KubeOne 1.8! Please consult the changelog below, as well as, the following two documents before upgrading:

• Upgrading from KubeOne 1.7 to 1.8 guide
• Known Issues in KubeOne 1.8

Changelog since v1.7.0

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

• Refactor example Terraform configs for Hetzner to randomly generate the private network subnet in order to support creating multiple KubeOne clusters (#3152, @xmudrii)
• The example Terraform configs for Azure have been migrated to use the Standard SKU for IP addresses. This is a breaking change for existing setups; in which case you should continue using your current SKU. Manual migration is possible by dissociating IP from the VM and LB, the migrating it, and assigning it back, however please consider all potential risks before doing this migration (#3149, @kron4eg)
• Credentials defined in the credentials file now have precedence over credentials defined via environment variables. This change is made to match the behavior that's already documented in the KubeOne docs. If you use both the credentials file and the environment variables, we recommend double-checking your credentials file to make sure the credentials are up to date, as those credentials will be applied on the next kubeone apply run (#2991, @kron4eg)
• kured has been removed, you have to re-enable it back in form of helmRelease (#3024, @kron4eg)
• OSM: The latest Ubuntu 22.04 images on Azure have modified the configuration for cloud-init and how it accesses its datasource in Azure, in a breaking way. If you're having an Azure cluster, it's required to refresh your machines with the latest provided OSPs to ensure that a system-wide package update doesn't result in broken machines. (#3172, @xrstf)
• Support for Docker is removed; containerRuntime.docker became a no-op. (#3008, @kron4eg)

v1.7.4

Changelog since v1.7.3

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

• Update operating-system-manager to v1.3.5. The latest Ubuntu 22.04 images ship with cloud-init 24.x package. This package has breaking changes and thus rendered our OperatingSystemProfiles (OSPs) as incompatible. It's recommended to refresh your machines with the latest provided OSPs to ensure that a system-wide package update, that updates cloud-init to 24.x, doesn't break the machines. (#3163, @xrstf)

Changes by Kind

Bug or Regression

• Clean yum cache upon configuring Kubernetes repos. This fixes an issue with cluster upgrades failing on nodes with an older yum version (#3147, @kubermatic-bot)
• Deploy user defined addons before the external CCM initialization. This fixes an issue with cluster provisioning for users that use both external CCM and external CNI (#3068, @kubermatic-bot)
• Fix cluster upgrades on Debian hosts with deprecated Kubernetes repositories (#3084, @kubermatic-bot)
