Someone on your team just asked for more storage for CI logs. Another needs direct object access for test artifacts. You sigh, open your terminal, and realize the fix is not more disks, it is smarter plumbing between Ceph and GitLab. The trick? Making identity, permissions, and pipelines talk to each other without duct tape.
Ceph is the backbone of distributed storage that actually scales. It shards, replicates, and heals your data across clusters without human babysitting. GitLab, on the other hand, runs the show for your code lifecycle. It builds, tests, and ships—all wrapped around access control and audit trails. When you link them right, you get infinite artifact storage and verifiable builds that still obey the same RBAC logic your compliance team loves.
Here is the idea: Ceph handles the blobs, GitLab handles the brains. The integration works best when GitLab runners authenticate to Ceph using tokens mapped from your main identity provider, such as Okta or AWS IAM. That way every job writes or reads from Ceph with traceable, ephemeral credentials. Pipeline secrets never linger. You get security parity across compute and storage.
A common configuration error is letting runners use static access keys. Instead, rotate S3-style credentials automatically with OIDC. Tie them to GitLab’s OAuth flow so each pipeline creates its own short-lived lease. If you ever need proof for SOC 2 or ISO audits, you can show when, where, and by whom data was accessed.
Quick answer: To connect Ceph to GitLab, use the Ceph Object Gateway (RGW) with S3-compatible endpoints. Point GitLab’s artifact or cache backend to that endpoint, and apply fine-grained IAM rules through OIDC tokens. This approach keeps artifacts durable, versioned, and secure.
