Release notes for kops 1.16 series

Breaking changes

• Support for Docker versions 1.11, 1.12 and 1.13 has been removed because of the dockerproject.org shut down. Those affected must upgrade to a newer Docker version.

• Please see the notes in the 1.15 release about the apiGroup changing from kops to kops.k8s.io

• A controller is now used to apply labels to nodes. If you are not using AWS, GCE or OpenStack your (non-master) nodes may not have labels applied correctly.

Significant changes

• If upgrading from 1.11 or earlier, please see the notes in previous releases about upgrading through kubernetes 1.12, with the etcd3 upgrade.

• A new component runs on the master nodes now: kops-controller. kops-controller currently labels nodes, but will likely perform additional functionality in future releases.

Required Actions

• If either a Kops 1.16 alpha release or a custom Kops build was used on a cluster, a kops-controller Deployment may have been created that should get deleted. Run kubectl -n kube-system delete deployment kops-controller after upgrading to Kops 1.16.0-beta.1 or later.

• Kubernetes 1.9 users will need to enable the PodPriority feature gate. This is required for newer versions of Kops.

To enable the Pod priority feature, follow these steps:

kops edit cluster
# Add the following section
spec:
  kubelet:
    featureGates:
      PodPriority: "true"

Deprecations

• Support for Kubernetes releases prior to 1.9 is deprecated and will be removed in kops 1.18.

• The kops/v1alpha1 API is deprecated and will be removed in kops 1.18. Users of kops replace will need to supply v1alpha2 resources.
