Changelog

0.4.0 (2017-06-26)

  • Added new chaos functionality. When used, blockade will randomly select containers to impair with partitions, slow network, etc. Contributed by John Bresnahan (@buzztroll) of Stardog Union.
  • Added an event trail that logs all blockade events that are run against a blockade over its lifetime. This can be helpful in correlating blockade events to application errors. Contributed by John Bresnahan (@buzztroll) of Stardog Union.
  • Substantially improved overall performance by using a cached container for all host commands.
  • #62: Fixed bug with using blockade commands against a restarted container. Contributed by John Bresnahan (@buzztroll) of Stardog Union.
  • Updated Docker SDK and API version. Contributed by Vladimir Borodin (dev1ant).

0.3.1 (2016-12-09)

  • #43: Restore support for loading from blockade.yml config file.
  • #26: Improved error messages when running blockade without access to the Docker API.
  • #25: Improved error messages when determining container host network device fails.
  • #40: Fixed kill command (broken in 0.3.0).
  • #1: Fixed support for configuring Docker API via DOCKER_HOST env.
  • #36: Truncate long blockade IDs to avoid iptables limits.
  • Switched to directly inspecting /sys for container network devices instead of via ip. This means containers no longer need to have ip installed.
  • Improved Blockade Python API by returning names of the containers a command has operated on. Contributed by Gregor Uhlenheuer (@kongo2002).
  • Fixed Vagrantfile to also work on Windows. Contributed by Oresztesz Margaritisz (@gitaroktato).
  • Documentation fix contributed by Konrad Klocek (@kklocek).
  • Added new version command that prints Blockade version and exits.
  • Added cap_add container config option, for specifying additional root capabilities. Contributed by Maciej Zimnoch (@Zimnx).

0.3.0 (2016-10-29)

  • Reworks all network commands to run in Docker containers. This allows Blockade to be run without root privileges, as long as the user can access Docker.
  • Introduces a REST API and daemon mode that allows creation and management of blockades remotely.
  • Adds ability to add a container to a running blockade, via add command.
  • Adds support for Docker user-defined networks to allow any-to-any communication between containers, without links. Contributed by Stas Kelvich (@kelvich).
  • Adds ability to configure DNS servers for containers in a blockade. Contributed by Vladimir Borodin (@dev1ant).
  • Adds a generic --random flag for many commands to allow easier randomized chaos testing. Contributed by Gregor Uhlenheuer (@kongo2002).
  • Introduces a new kill command for killing containers in a blockade.
  • Fixed links to Docker documentation. Contributed by @joepadmiraal.
  • Fixed links of named containers. Contributed by Gregor Uhlenheuer (@kongo2002).

0.2.0 (2015-12-23)

  • #14: Support for docker >1.6, with the native driver. Eliminates the need to use the deprecated LXC driver. Contributed by Gregor Uhlenheuer.
  • #12: Fix port publishing. Breaking change: the order of port publishing was swapped to be {external: internal}, to be consistent with the docker command line. Contributed by aidanhs.
  • Introduces new duplicate command, which causes some packets to a container to be duplicated. Contributed by Gregor Uhlenheuer.
  • Introduces new start, stop, and restart commands, which manage specified containers via Docker. Contributed By Gregor Uhlenheuer.
  • Introduces new random partition behavior: blockade partition --random will create zero or more random partitions. Contributed By Gregor Uhlenheuer.
  • Reworked the blockade ID generation to be more like docker-compose, instead of using randomly-generated IDs. If --name is specified on the command line, this is used as the blockade ID and is prefixed to container names. Otherwise the blockade name is taken from the basename of the current working directory.
  • Numerous other small fixes and features, many contributed by Gregor Uhlenheuer. Thanks Gregor!

0.1.2 (2015-1-28)

  • #6: Change ports config keyword to match docker usage. It now publishes a container port to the host. The expose config keyword now offers the previous behavior of ports: it makes a port available from the container, for linking to other containers. Thanks to Simon Bahuchet for the contribution.
  • #9: Fix logs command for Python 3.
  • Updated dependencies.

0.1.1 (2014-02-12)

  • Support for Python 2.6 and Python 3.x

0.1.0 (2014-02-11)

  • Initial release of Blockade!
