1.5.0

Changes

The only change in this version is the transference of all specialized support nodes previously included with this platform engine into their own repositories. This change seeks to improve maintainability of the platform engine, separation of the support nodes issues, requirements and enhancements from those of the platform and, finally, endorse shared ownership of the nodes.

The new home for those support nodes are:

OpenSwitch support node:

https://github.com/HPENetworking/topology_docker_openswitch

Open vSwitch support node:

https://github.com/HPENetworking/topology_docker_openvswitch

P4Switch support node:

https://github.com/HPENetworking/topology_docker_p4switch

Ryu Controller support node:

https://github.com/HPENetworking/topology_docker_ryu

1.4.0

New

• The binds attribute can now be injected and extended by users. If you require to add a new bind directory to a node you may now specify the attribute binds (and thus, also use attribute injection) separating the pair of binded directories with a ;. For example:

  /host/a:/container/a;/host/b:/container/b

• OpenSwitch support node will now notify the container when the setup of the interfaces is done. This fixes many potential race conditions on container initialization. To be able to use this new feature an OpenSwitch image of a date greater than March 4 2016 is required.

Changes

• Set topology minimal version to 1.5.0.

• Internal docker exec shell layer migrated to Topology’s new shell API, available since 1.4.0 and improved in 1.5.0.

Fixes

• OpenSwitch support node will now ignore the bonding_masters interface when creating setting up the ports.

• Fixed a race condition in OpenSwitch support node caused by a slower than normal db schema setup in ovsdb. This race conditions caused an IndexError when setting up the image, causing the topology build to rollback.

1.3.0

Changes

• Node’s/Container’s hostname can now be set using the hostname attribute in the SZN description. OpenSwitch will always enforce the switch hostname for all nodes of this type.

• Docker-py’s will now use the server’s API version, instead of the latest. With this it will no longer required to update the Docker daemon to run topology tests.

• Set topology minimal version to 1.2.0.

1.2.0

Changes

• Refactored node loading logic to use topology.platforms.utils.NodeLoader instead.

1.1.0

New

• Added Dockerfiles for Ryu and P4.

Changes

• The Open vSwitch node will now check that the openvswitch kernel module is loaded. It is supposed to work in user space, but we discovered many race conditions without the kernel module. Check the documentation of the openvswitch node for more information.

Fixes

• Improved openswitch’s vtysh prompt regular expression to avoid false positives matches.

• Fixed a bug on shell management that caused the echo of the command to be included in the output, and thus interpreted as failed.

1.0.0

• Initial public release.
