Added

  • Expose Prometheus metrics for Agent and Controller using the "/metrics" apiserver endpoint; "enablePrometheusMetrics" must be set to true in configuration.
  • Add documentation for deploying Prometheus and scraping Antrea metrics, along with sample YAML manifest.
  • Install portmap CNI by default in order to support Pods with "hostPort" set.
  • Support configurable ports for Agent and Controller apiservers.
  • Set default CPU resource requests for Antrea components in YAML manifest.
  • Add "/ovsflows" API endpoint to Agent to query OVS flows and "antctl get ovsflows" command; flows can be filtered by Pod / NetworkPolicy / OVS Table.
  • Improvements to "/networkpolicies" API endpoint and "antctl get networkpolicies" command:
    • namespace and name parameters to filter policies
    • ability to get NetworkPolicies applied to a Pod (Agent API only)
  • Add object type aliases to antctl (plural form and short alias).
  • Document known issues when deploying Antrea on Photon OS or CoreOS.

Changed

  • Add authentication to Agent apiserver to enable external access (from outside of Agent Pod), and generate bearer token for local access instead of delegating authentication to K8s apiserver.
  • Send Agent and Controller logs to /var/log/antrea/ on the host as well as stderr.
  • Make "table" output format the default for antctl get commands.
  • Use custom formatter for logs originating from ofnet / libOpenflow (which use the logrus module) to mimic K8s log format.
  • Use Go cross compilation support for "make bin": Antrea Linux binaries can now be built on other OS's.
  • Ensure that OVS bridge datapath type is correct when Agent starts.

Fixed

  • Acquire xtables.lock before executing iptables-restore in Agent to avoid initialization error when kube-proxy uses iptables concurrently.
  • Start ovs-vswitchd with flow-restore-wait config (only for OVS system datapath type) to avoid conntrack issues after antrea-ovs restarts; this could also reduce downtime during upgrades.
  • Fix monitoring CRDs update: recover gracefully from transient errors.
  • Handle DeletedFinalStateUnknown in NetworkPolicy Controller to avoid crashes when a watch deletion event is missed, e.g. because of a transient connectivity issue to the K8s apiserver.
