Hi everyone,

This is a quick reminder that the /apps/segmentrouting and /apps/t3 modules are being moved into their own Gerrit/git repositories as part of the 2.5.0 release. The work to do this has started and the removal of these modules from the main ONOS code-base will be done as a last step.

In the interest of reducing conflicting patches, please refrain from making changes to this code unless you coordinate with Charles or Pier who are leading this effort. Thanks in advance.

More information on how to work on these modules in their own repos will be available at a later time.

Cheers!

Thomas

Hi everyone,

We have completed the separation of Trellis-specific apps (segmentrouting and t3).

What have we done?

• segmentrouting is now hosted in trellis-control repo in ONOS gerrit. You can download the source code by running
  git clone https://gerrit.onosproject.org/trellis-control
  There is also a mirror repo set up on github
  https://github.com/opennetworkinglab/trellis-control
• t3 is now hosted in trellis-t3 repo in ONOS gerrit. You can download the source code by running
  git clone https://gerrit.onosproject.org/trellis-t3
  There is also a mirror repo set up on github
  https://github.com/opennetworkinglab/trellis-t3
• Jenkins verification jobs have been set up accordingly for the new repos.
• Documentation in https://docs.trellisfabric.org is also updated. You need to switch to master branch from the default 1.12 branch.
• New artifacts of segmentrouting and t3 are published on Sonatype. We haven't done an official release of segmentrouting and t3 yet. We plan to do that in early Q3, and when we do, those will be available on maven central as well.
• /apps/segmentrouting and /apps/t3 have been completely removed from ONOS master branch.
• New Trellis app starts with 3.x version number, in order to avoid confusion of the past 1.x and 2.x when Trellis was still part of ONOS.

How does it change the way we build/run ONOS and Trellis?

• ONOS still needs to be built/installed in the same way. You can download the source and build by bazel, or run the published docker container directly.
  
• New build and installation process for segmentrouting: https://github.com/opennetworkinglab/trellis-control/blob/master/README.md
• New build and installation process for t3: https://github.com/opennetworkinglab/trellis-t3/blob/master/README.md
• Code reviews should still go through gerrit, not github
  

Feel free to let me know if you face any issue.

Thanks,
