Added
- Example manifests use new
node-role.kubernetes.io/control-planetolerations in addition to legacynode-role.kubernetes.io/master. - Added release pipeline which will be building release container images from now on.
- Added compatibility with Kubernetes versions v1.24+.
kustomization.yamlfile has been added to example manifests to enable using them withkustomize.
Changed
- Moved from
github.com/flatcar-linux/flatcar-linux-update-operatortogithub.com/flatcar/flatcar-linux-update-operator. This also means that the docker images will be now available atghcr.io/flatcar/flatcar-linux-update-operator. The0.8.0image is still available at the old location, but no new images will be pushed there. - Everything is now built using Go 1.19.
- Updated all Go dependencies.
- Dropped dependency on
github.com/flatcar-linux/locksmith. - In example manifests use Role resource instead of ClusterRole where possible to limit scope of permissions.
- Limited operator access to config maps only to one used for leader election in example manifests.
- Improved agent responsiveness to context cancellation.
- Agent code is now covered with tests and some initial refactorings has been performed.
- Container images now use Alpine Linux version v3.15 as a base image.
- Draining pods is now done using Eviction API when possible.
- Capitalization of log messages and formatting of produced errors is now more consistent.
latesttag for container images will no longer be used. Users are recommended to use specific versions.
Fixed
- Publishing leader election events by operator.
- Agent main loop leaking goroutine when agent is stopped.
- Used service account by agent in example manifests.
Removed
- Unused RBAC permissions from agent and operator example manifest.
- Unreachable agent code.
- Deprecated
--auto-label-flatcar-linuxflag has been removed from operator. - Pod Security Policies has been removed from example manifests, as their support has been removed in Kubernetes 1.25.
