## Context This is part of the work to upgrade and migrate the GitLab.com container registry to a new version backed by a metadata database and online garbage collection (https://gitlab.com/groups/gitlab-org/-/epics/5523). This will be achieved following the gradual migration plan detailed in https://gitlab.com/gitlab-org/container-registry/-/issues/374. For the gradual [Phase 1](https://gitlab.com/gitlab-org/container-registry/-/issues/374#phase-1-the-metadata-db-serves-new-repositories) (new repositories only) production rollout, we'll split the work into three portions, in this order: 1. **GitLab Org**: We'll start by testing with some custom-made container repositories under `gitlab-org/` and then allow all of its new container repositories to be handled by the metadata DB; 1. **General**: Following the GitLab Org rollout, we will proceed with a general percentage-based roll out for everyone, excluding major customers (see next); 1. **Major customers**: To reduce the risk of impacting users of the GitLab.com container registry that have large amounts of data, a very high activity, or very high availability/stability requirements, we will exclude these from (2) and handle them in this step with a manual gradual rollout, customer by customer. ## Task Perform general percentage-based rollout (2) for new container repositories. We will be doing this in stages. ### Stages The number of stages and the rate at which we move through them (i.e. percentage increments within the same stage) may change depending on how the deployment goes. 1. [x] [[1%, 10%]](https://gitlab.com/gitlab-org/container-registry/-/issues/467) 1. [x] [[11%, 20%]](https://gitlab.com/gitlab-org/container-registry/-/issues/468) 1. [x] [[21%, 30%]](https://gitlab.com/gitlab-org/container-registry/-/issues/470) 1. [x] [[31%, 50%]](https://gitlab.com/gitlab-org/container-registry/-/issues/471) 1. [x] [[51%, 70%]](https://gitlab.com/gitlab-org/container-registry/-/issues/472) 1. [x] [[71%, 100%]](https://gitlab.com/gitlab-org/container-registry/-/issues/473) We will update the percentage of actors (top-level namespaces) for which the [`container_registry_migration_phase1_allow`](https://gitlab.com/gitlab-org/gitlab/-/issues/335705) feature flag is enabled.
