Added

  • Added golangci-lint and codespell CI jobs using GitHub Actions.
  • Added CI for vendor directory, generated files, Go modules tidiness, Dockerfile etc.
  • Added missing documentation for all packages.
  • Added integration tests for pkg/updateengine.
  • Added unit tests for pkg/operator.

Changed

  • Updated used Go version to 1.16 and Alpine version for container images to 3.14.
  • Container images will be now published to ghcr.io/flatcar-linux/flatcar-linux-update-operator instead of
    quay.io/kinvolk/flatcar-linux-update-operator.
  • update-agent now use a dedicated Service Account with lower privileges than the operator.
  • update-agent now use a dedicated Pod Security Policy.
  • update-operator now use more strict Pod Security Policy, as it no longer needs permissions
    for agent related resources.
  • Flatcar Linux references has been changed to Flatcar Container Linux.
  • Migrated from glog to klog,
    which is a recommended logger for Kubernetes operators.
  • pkg/drain has been integrated into pkg/k8sutil.
  • Errors returned from operator and agent runs are now properly wrapped and can be unwrapped by the user.
  • Remaining CoreOS references has been replaced with Flatcar.
  • pkg/k8sutil.GetVersionInfo() will now return an error when /etc/flatcar/update.conf file is present,
    but not readable.
  • Marking node as Unschedulable should now be more robust on frequent Node object updates.
  • Renamed Go module from github.com/kinvolk/flatcar-linux-update-operator to github.com/flatcar-linux/flatcar-linux-update-operator, following the move of repository into new organization.

Fixed

  • Fixed various typos found by codespell.
  • Operator will no longer leak leader election goroutine, it will be now shut down when stop channel gets closed.
  • Operator will now internally gracefully return an error when leader election is lost, so process can be restarted
    to start a new leader election.

Removed

  • Removed no longer used Travis CI, Jenkins configuration files and build scripts.
  • Removed AttemptUpdate(), GetStatus() and RebootNeededSignal() functions from pkg/updateengine package.
  • Removed deprecated --manage-agent, --agent-image-repo and --analytics flags from update-operator.
  • Deprecated operator functionality to manage agent DaemonSet has been removed. Agent DaemonSet must be now deployed separately.
