Maintainers

Cilium is governed by a group of maintainers and committers documented in MAINTAINERS.md. Project governance lives at cilium/community/GOVERNANCE.md. Special Interest Group ownership is in cilium/community/sigs.yaml.

This page maps the major subsystems in this repo to recent contributors. Where a subsystem has explicit CODEOWNERS (see the CODEOWNERS file at the repo root, ~38 KB), those entries are authoritative; the table below is derived from MAINTAINERS.md and recent git log.

Author and committer ladder

The contributor ladder in cilium/community/CONTRIBUTOR-LADDER.md defines how Reviewers and Committers are nominated. New committers are added by majority vote of existing committers. Emeritus committers — listed in MAINTAINERS.md — are recognised for past contributions.
