Duffy is the middle layer running ci.centos.org that manages the provisioning, maintenance and teardown / rebuild of the Nodes (physical hardware for now, VMs coming soon) that are used to run the tests in the CI Cluster.
Community Platform Engineering team (of Red Hat) is working on revamping this project and thus, have cleaned this repository by marking other branches stale and creating new branches for development. In order to see the current deployed version of Duffy in CentOS CI Infra, please check stale/master branch.
