Skip to main contentRecommended upgrade strategy to ensure zero downtime and safe production rollouts.
Rolling updates
- Deploy new service replicas alongside existing ones
- Gradually shift traffic to the updated replicas
- Retire older replicas only after health checks pass
Database migrations
- Always test migrations in a staging environment before production
- Prefer backward-compatible schema changes
- Avoid dropping or renaming columns while serving live traffic
Rollbacks
- Retain previous Docker images to allow quick rollback
- Revert database changes using rollback or down migration scripts when required
- Validate application behavior and data integrity before restoring full traffic
