Changelog

[Unreleased]

Added

  • Cleanup stage added where systemd units without corresponding pods are removed on startup (#312).

Changed

  • Changed the version reported by the Stackable Agent in nodeInfo.kubeletVersion of the Node object in Kubernetes from the version of the Krustlet library to the Stackable Agent version (#315).
  • Restart agent on all crashes (#318).
  • Agent will now request content type "application/gzip" in package downloads and reject responses with content type that is not one of either "application/gzip", "application/tgz" or "application/x-gzip" (#326)
  • Agent now also accepts "application/x-tgz" as content_type when downloading packages (#337)

Fixed

  • Agent deletes directories from failed install attempts (#326)

[0.6.1] - 2021-09-14

Changed

  • Changed the binary location for APT packages from /opt/stackable-agent/stackable-agent to /opt/stackable/stackable-agent/stackable-agent (#304).

[0.6.0] - 2021-09-08

Added

  • Prints self-diagnostic information on startup (#270).
  • Check added on startup if the configured directories exist and are writable by the Stackable agent (#273).
  • Missing directories are created (#274).
  • Annotation featureRestartCount added to the pods to indicate if the restart count is set properly (#289).

Changed

  • Lazy validation of repository URLs changed to eager validation (#262).
  • certificates.k8s.io/v1 used instead of certificates.k8s.io/v1beta1 so that the Stackable Agent is now compatible with Kubernetes v1.22 but not any longer with versions prior to v1.19 (#267).
  • Error message improved which is logged if a systemd unit file cannot be created (#276).
  • Handling of service restarts moved from the Stackable agent to systemd (#263).

Removed

  • Check removed if a service starts up correctly within 10 seconds. systemd manages restarts now and the Stackable agent cannot detect if a service is in a restart loop (#263).

Fixed

  • Systemd services in session mode are restarted after a reboot (#263).

[0.5.0] - 2021-07-26

Added

  • hostIP and podIP added to the pod status (#224).
  • Environment variable KUBECONFIG set in systemd services (#234).

Fixed

  • Invalid or unreachable repositories are skipped when searching for packages (#229).
  • Access rights of the private key file restricted to the owner (#235). The permissions are set when the file is created. On existing installations the permissions must be set manually, e.g. with chmod 600 /etc/stackable/stackable-agent/secret/agent.key.

[0.4.0] - 2021-06-23

Added

  • Annotation featureLogs added to the pods to indicate if logs can be retrieved with kubectl logs (#188).

Changed

  • Restart setting in systemd units removed because the agent already monitors the units and restarts them according to the restart policy in the pod spec (#205).

Fixed

  • Pods with restart policy Never handled correctly (#205).

[0.3.0] - 2021-05-27

Added

  • Artifacts for merge requests are created (#169, #173).

Changed

  • Structure of the documentation changed so that it can be incorporated into the overall Stackable documentation (#165).

Fixed

  • Deadlock fixed which occurred when multiple pods were started or stopped simultaneously (#176).

[0.2.0] - 2021-05-20

Added
