Title

OpenDaylight CI Pipelines using Containers

Status

APPROVED

Difficulty

HIGH

Description 

OpenDaylight's CI [1.] jobs are presently using Jenkins-job-builder (JJB) [2.] with the entire job configuration maintained as code in the releng/builder [3.], releng/global-jjb [4.] and common-packer [5.] repositories. The CI infrastructure has around 2k+ jobs that are written using yaml/shell/python many of which need to migrate to CI pipelines. The pipeline job prototype should be able to do a complete lifecycle (from code changes picked up from merged/staged job to be deployed and tested on containers images (these images are equivalent of VM image instance - mininet, devstack, etc presently built on the infrastructure). The work requires updating the packer files to build containers and converting the JJB/yaml code to CI pipelines.

Learning Objectives

The intern will gain experience contributing to OSS and OpenDaylight CI tools (not limited to Jenkins, pipelines, CI/CD, packer. etc).

Expected Outcome

  • Create Dockerfiles for all the VMs used in Jenkins (builder, robot, mininet, etc), also try to consolidate in few images (the less, the better).
  • Create Jobs that build and maintain container images (e.g. verify, merge, release).
  • Migrate existing jobs (VM based) to Jenkins pipeline jobs (container based) - bonus
