⚠ kOps 1.21 has not been released yet! ⚠
This is a document to gather the release notes prior to the release.
kOps now supports extending the control plane with dedicated apiserver nodes. These nodes run in dedicated instance groups that can be scaled horizontally.
In 1.21, this feature is behind a feature flag as node role name, labels, taints, and domains can change based on feedback from the community.
- Protokube now runs as a systemd process rather than a docker container.
- Support for Kubernetes versions 1.15 and 1.16 are deprecated and will be removed in kOps 1.22.
- Support for launch configurations has been removed in favour of launch templates.
