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)

Updates

machine-controller

• Update machine-controller to v1.57.6 (#3064, @ahmedwaleedmalik)

v1.6.6

Changelog since v1.6.5

Urgent Upgrade Notes

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

• Update operating-system-manager to v1.2.5. 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. (#3164, @xrstf)

Changelog since v1.7.1

Urgent Upgrade Notes

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

• Fix determining the CLUSTER_NAME environment variable for OpenStack CCM DaemonSet and OpenStack Cinder CSI Deployment. This fixes a regression where the cluster name was changed to kubernetes upon running kubeone apply two or more times after upgrading from KubeOne 1.6 to KubeOne 1.7. This regression might affect Octavia Load Balancers, making them fail to reconcile. Please check the known issues document to find if you're affected by this issue and what steps you need to take if you're affected (#2979, @kubermatic-bot)
