Kubernetes Version Compatibility

The daemon image contains a 1.17.x k8s.io/client-go and kubectl binary for the purposes of maintaining the lock and draining worker nodes. Kubernetes aims to provide forwards & backwards compatibility of one minor version between client and server, so this should work on 1.1[678].x.

Tested in minikube on 1.16.9, 1.17.5, 1.18.2.

Kured 1.3.0

This release has been a longer while coming - thanks for hanging in there everyone. Most importantly it adds support for newer k8s client tools and updates other internal build builds, adds Slack channel name configuration (#87) and an option to only reboot within a configured time window (#66).

Improvements

• Use newer version of k8s client tools (#111)
• add development docs (#112)
• Update go.mod and go.sum after 'go mod vendor' (#86)
• Upgrade to latest alpine (#100)
• Ad Slack channel name configuration (#87)
• Reboot only within time window specified on commandline (#66)

Kubernetes Version Compatibility

The daemon image contains a 1.15.x k8s.io/client-go and kubectl binary for the purposes of maintaining the lock and draining worker nodes. Kubernetes aims to provide forwards & backwards compatibility of one minor version between client and server, so this should work on 1.15.x and 1.17.x.

Tested in minikube on 1.15.10, 1.16.7 and 1.17.3.

Kured 1.2.0

Improvements

• Support for blocking reboot of individual nodes based on the presence of pods with specific labels

Kubernetes Version Compatibility

The daemon image contains a 1.13.x k8s.io/client-go and kubectl binary for the purposes of maintaining the lock and draining worker nodes. Kubernetes aims to provide forwards & backwards compatibility of one minor version between client and server, so this should work on 1.12.x and 1.14.x.

Tested in minikube on 1.12.8, 1.13.6 & 1.14.1.

Kured 1.1.0

Improvements

• RBAC support
• Use the systemctl in the host mount namespace to effect reboots, reducing image size and eliminating the potential for incompatibility
• Notify Slack on drain in addition to reboot
• Pass through log output from invoked kubectl commands
• Tolerate NoSchedule taint on node-role.kubernetes.io/master
• Fixed reversal of daemonset name/namespace arguments and comments in the manifest

Kubernetes Version Compatibility

The daemon image contains a 1.12.x k8s.io/client-go and kubectl binary for the purposes of maintaining the lock and draining worker nodes. Kubernetes aims to provide forwards & backwards compatibility of one minor version between client and server, so this should work on 1.11.x and 1.13.x.

Tested in minikube on 1.11.4, 1.12.1 & 1.13.0-alpha.2.
Tested in production on 1.11.2 & 1.12.2.

Kured 1.0.0

Kubernetes Version Compatibility

The daemon image contains a 1.7.x k8s.io/client-go and kubectl binary for the purposes of maintaining the lock and draining worker nodes. Whilst it has only been tested on a 1.7.x cluster, Kubernetes typically has good forwards/backwards compatibility so there is a reasonable chance it will work on adjacent versions; please file an issue if this is not the case.
