Senior DevOps / SRE [L2] Git resolve conflicts, then: Production Scenario [L2]

Q: Your company has multiple Git remotes — the primary on GitHub, a mirror on GitLab for CI, and a backup on an internal server. How do you manage pushing to all of them?

Production Solution & Architecture

Git supports multiple remotes natively. Set them up: Option 1: Push to each explicitly: Option 2: Configure a push URL group — add multiple push URLs to a single remote: Now git push origin main pushes to all three simultaneously. git pull still fetches from the first (fetch) URL. Option 3: CI-driven mirroring — a post-push webhook or CI job on GitHub that mirrors to GitLab and the internal server. This is the most reliable approach for teams because it's centralized and auditable. Verify your setup: Shows fetch and push URLs for each remote. Best practice: designate one remote as the "source of truth" (usually origin). Mirrors should be read-only replicas populated by automation, not by developers pushing manually, to avoid divergence.

git remote add github https://github.com/org/repo.git
git remote add gitlab https://gitlab.com/org/repo.git
git remote add backup git@internal-server:org/repo.git

⚡ 60-Second Elevator Pitch Talking Points

Immediate Triage: Git supports multiple remotes natively. Set them up:
Run targeted verification commands before modifying configuration.
Automate permanent guardrails (CI check, alerts, IaC policy) to prevent recurrence.
