How We Work

Project Management

Issue Tracking

The Cells Infrastructure team works across multiple GitLab projects such as gitlab-org/gitlab, gitlab-org/cells/http-router, gitlab-org/cells/topology-service, and gitlab-com/gl-infra/gitlab-dedicated/instrumentor. By default, you should open issues that will be owned by the team under the Cells Infrastructure Team Issue Tracker and apply the group::cells infrastructure label. Move issues for the Cells Infrastructure team from other projects to the team issue tracker when appropriate.
