[v0.8.0] - 2021-05-03

This release coincides with Cilium 1.10 and has support for new API additions added in Cilium. Some of the new API features include support for agent and debug events (#537), as well as prelimary support for the experimental Hubble Recorder API (#530). Both of these features are currenlty only available via the local unix domain socket. Other API features include filtering by TCP flags (#461), IP version (#505) and node name (#412).

Hubble CLI 0.8 also comes with improvements to the CLI utility, such as reading flows and filtering flows from stdin (#524), more flexible timestamp format printing (#509), support for Apple silicon (#488), as well as miscellaneous flag improvements and additions (#411, #420, #421, #443). It also contains a new hubble list subcommand which, when targeting Hubble Relay, lists all Hubble enabled nodes (#427).

Breaking Changes

In accordance with semver 0.x releases, this release contains a few breaking changes to the Hubble command-line interface:

  • The new default Hubble API endpoint (specified with --server) is now localhost:4245 to ease usage with Hubble Relay. To connect to the local unix domain socket, use --server unix:///var/run/cilium/hubble.sock or set the HUBBLE_SERVER environment variable (default within a Cilium container) (#535)
  • The new default output format is now always compact regardless of being in follow-mode or not. To obtain the old table output in the hubble observe command, use --output=table (#536)
  • The source of reply packets is now printed on the left side in the compact output format. Such flows are indicated with a <- arrow instead of ->. Flows with an unknown direction now use the <> arrow in the compact output (#533).
  • The hidden hubble peers watch command has been renamed to hubble watch peers (#542)

  • Add basic support for agent events (#442, @tklauser)
  • Add subcommands for agent and debug events (#537, @tklauser)
